Can Congress cut food waste? It depends on the success of this bill @codyboteler

(WASTE DIVE) by Cody Boteler: For decades, the federal government has regulated how landfills operate, how air and water are protected and how dangerous sites are cleaned up. However, the federal government has yet to implement a national policy on how to handle food waste.

The lack of federal guidance on food waste has left the U.S. with a patchwork of food waste solutions, with some states, like New Jersey, pursuing ambitious food waste goals — while others seem to all but ignore the issue. Now with the introduction of the Food Recovery Act (H.R. 3444), a vision of what could become the first national food waste policy is taking shape. A similar measure was introduced in 2015, but did not make it out of committee.

Rep. Chellie Pingree introduced the legislation at the end of June, and it has been referred to half a dozen House committees. Sen. Richard Blumenthal introduced the same legislation in the Senate a few days later. While some time may pass before either measure comes to a vote — especially since Congress is now in recess — even a trimmed-down version of the introduced measures would have wide-ranging implications for how the U.S. handles food waste. Featured here is a breakdown of some of the impacts of the legislation, if enacted into law. 

Implications for anaerobic digestion (AD)

One of the biggest implications from the bill is the new requirements it would put on anyone seeking a grant or a loan from the federal government to install an anaerobic digester. In order to qualify for the loan or grant, the AD operator would have to submit two items to the Department of Agriculture: a written agreement to adhere to the Environmental Protection Agency's (EPA) food recovery hierarchy and a written plan on what to do with the digestate that's left behind after biogas is produced from AD.

The law would also prohibit the Department of Agriculture from issuing loans to AD operations that use only manure, and require the department to give preference to AD operations that use "primarily" food waste. This requirement could prove to be a boon for energy production, as food scraps and other food waste have a much higher energy potential than manure from any animal.

Implications for schools

Schools will be encouraged — though not required — to purchase "lower-price, nonstandard-size or -shape produce." Put more simply: Schools will be encouraged to purchase ugly food for their nutritional programs.

"Ugly food," which is largely made up of misshapen or slightly damaged produce, is just as healthy and safe as conventional-looking produce. However it often goes to waste on a retail-level because grocery stores don't want to stock it and turn off customers. By introducing ugly food in schools, the education system would not only help combat the food waste issue, but would also expose a younger generation to accepting and eating food that may look unconventional.

Implications for the private sector

Date labels, a longtime bane of food waste advocates, would finally be standardized on the federal level. Under the legislation, if a labeler wants to include a "quality" label, they must use the phrase "BEST if Used By." Any food that could expire, or would otherwise require a safety label, will need to have the phrase "USE By." This mandated distinction will, ideally, lead to fewer consumers tossing out food if they're unsure whether it's safe to consume. An optional "Freeze By" label would also be permissible.

The Bill Emerson Good Samaritan Food Donation Act would be lightly amended to further protect those whom food is being donated to. The law would be amended to specify that "apparently fit" grocery products and "apparently wholesome" food meet "safety and safety-related" standards, not just "quality and labeling" standards as the law currently reads.

It would also become easier to donate food. The passage of the date on a date label would be codified as not being a barrier to legal protection after donating food.

DOE Announces Six Projects for Manufacturing of Biofuels, Bioproducts, Biopower

Energy Department Announces Six Projects for Pilot- and Demonstration-Scale Manufacturing of Biofuels, Bioproducts, and Biopower the selection of six projects for up to $12.9 million in federal funding, entitled, "Project Definition for Pilot- and Demonstration-Scale Manufacturing of Biofuels, Bioproducts, and Biopower." These projects, required to share the cost at a minimum of 50%, will develop and execute plans for the manufacturing of advanced or cellulosic biofuels, bioproducts, refinery-compatible intermediates, and/or biopower in a domestic pilot- or demonstration-scale integrated biorefinery. 

The projects will be evaluated in two phases. Award recipients will design and plan their facilities in Phase 1. In order to continue to Phase 2, projects will be evaluated on Phase 1 progress, as well as the ability to secure the required 50% cost share funding for Phase 2. DOE anticipates Phase 2 awards to be made in fiscal year 2018 to construct and operate the pilot- or demonstration-scale facility. Projects could receive additional federal funds of up to $15 million for pilot-scale facilities or $45 million for demonstration-scale facilities.   

The six Phase 1 projects will utilize thermochemical, biochemical, algal, and hybrid conversion technologies to generate the data required to enable future commercial-scale facilities.

Demonstration-Scale Integrated Biorefineries:

  • AVAPCO, LLC (Atlanta, Georgia): The AVAPCO, LLC ($3.7 million) project will develop a demonstration-scale integrated biorefinery that combines AVAPCO's biomass-to-ethanol process with project partner Byogy's alcohol-to-jet process to create an integrated process that produces jet fuel from woody biomass. In addition to the jet fuel primary product, the demonstration facility will also produce cellulosic renewable diesel and other bioproducts with another project partner, Genomatica. 
  • LanzaTech, Inc. (Skokie, Illinois): LanzaTech, Inc. ($4 million) has brought together a large team to design, construct, and operate an integrated demonstration-scale biorefinery that will use industrial waste gases to produce 3 million gallons per year of low-carbon jet and diesel fuels. LanzaTech and the Pacific Northwest National Laboratory have already successfully demonstrated their renewable jet fuel production technology.

Pilot-Scale Integrated Biorefineries:

  • Global Algae Innovations (San Diego, California): Global Algae Innovations ($1.2 million) has developed novel technologies that improve several stages of the algae production process. This project seeks to design a pilot-scale algae biofuel facility with improved productivity of open pond cultivation and more energy-efficient algae harvest. 
  • ThermoChem Recovery International, Inc. (Baltimore, Maryland): ThermoChem Recovery International, Inc. ($0.8 million) will work in collaboration with project partners to design a pilot-scale integrated biorefinery to produce transportation fuels from woody waste and agricultural feedstocks. The project proposes many improvements throughout the system, which in combination would allow for smaller, more cost-effective integrated biorefineries with increased liquid fuel yield. 

Pilot-Scale Waste-to-Energy Projects:

  • Rialto Bioenergy, LLC (Carlsbad, California): Rialto Bioenergy LLC ($2 million) plans to design the Rialto Advanced Pyrolysis Integrated Biorefinery facility that will have the capacity to convert 300 tons per day of biomass such as food extracted from municipal solid waste and wastewater treatment plant biosolids into a high-nutrient fertilizer and up to 6.4 megawatts of carbon-negative, renewable biopower. 
  • Water Environment & Reuse Foundation (Alexandria, Virginia): Water Environment & Reuse Foundation ($1.2 million) will design a pilot-scale integrated biorefinery that utilizes wastewater treatment plant sludge. This project will convert residual sludge and solids into biocrude oil, biogas, and fertilizer. The biocrude oil, when upgraded, is comparable to fossil-derived crude and can produce a variety of fuels including gasoline, jet fuel, and diesel with nearly zero net carbon emissions. The biogas produced by the system will be used to offset power needs elsewhere in the plant or will be sold to the grid.

Will California Climate Regulations Trump a Weak EPA? via @JessicaHrdcstle

(EnvironmentalLeader -Jessica Lyons Hardcastle) President-elect Donald Trump is expected to announce his pick to lead the EPA any day now. And assuming Trumpsticks to his campaign promises, the new EPA administrator will be spending more time dismantling all of President Obama's climate rules — such as the Clean Power Plan and Clean Water Rules — than enforcing the nation's air and water pollution regulations.

Meanwhile, California regulators are moving ahead with the most ambitious climate targets in North America.

On Friday, the California Air Resources Board (CARB) released its draft plan to reduce greenhouse gas emissions by40 percent below 1990 levels by 2030. The state plans to achieve these steep carbon cuts through a series of actions including low- and zero-emissions vehicles, cap-and-trade regulations, waste diversion from landfills and water conservation, and possibly a carbon tax.

"Now more than ever, the nation — and the world — are looking to California for leadership on climate change and air quality," said CARB chair Mary D. Nichols in a statement. "Denial is not an option. We must plan, invest and transform."

Days earlier, CARB rolled out its revised draft of the state's proposed short-lived climate pollutant strategy, aka the cow farts regulation. Senate Bill 1383, recently signed into law by Gov. Jerry Brown, requires the state to reduce super pollutants and targets a 40 percent methane emissions reduction below 2013 levels by 2030. The revised draft of the short-lived climate pollutant strategy outlines how regulators can work with the dairy industry and other stakeholders to make this happen.

Why should businesses outside of California care about any of this? The short answer is that many companies do business in California and other states so greenhouse gas emissions from their products and services sold outside of the golden state affect their overall carbon footprint. And despite a more lenient federal EPA under Trump, other states may follow California's lead in enacting tougher climate rules.

"All the US EPA does is set a standard," said attorney William Anaya, an officer in the environmental litigation group at Greensfelder, Hemker & Gale, in an interview. "States can be more stringent if they wish and they are — California being one of them — all up and down the West Coast. California will continue to be a leader, telling the rest of the world how to do that calculation: take less raw materials, create less waste and come up with more finished goods."

Dairy farms and other agriculture interests outside of California may face tougher methane emissions reductions under the short-lived climate pollutant strategy, said Todd Palmer, practice group chair of the environmental & natural resources and energy law practices at Michael Best.

"California's plan will likely culminate in a requirement that California dairies install anaerobic digestion systems [to reduce methane emissions,]" Palmer said in an interview. "Dairies located outside of the state may have installed anaerobic digestions systems on a voluntary basis to manage their manure and many of those non-California dairies have been participating in the California cap-and-trade program."

Palmer's clients include several of these non-California dairies. They participate in the state's cap-and-trade program because they receive carbon credits for implementing CARB-approved emission reduction equipment such as anaerobic digesters.

"Anaerobic digesters that currently exist outside of California will likely be grandfathered in," Palmer said. "But in other states when a dairy is looking at the capital expense and the operations and maintenance associated with an anaerobic digesters, one of the more significant revenue streams would be the credits from the cap and trade program. If those are no longer an option, that may affect whether or not those out-of-state digesters get built."

But it is not all bad news, Palmer says. The California short-lived climate pollutant strategy also sets aside state money in the form of grants and incentives to develop anaerobic digestion systems as well as infrastructure to pipe biogas from methane — a valuable low-carbon transportation fuel — throughout the state.

"I've talked to companies that provide services and engineering and products in that space, and they've been watching the development of California and that program because they see it as a market opportunity, a growth plan," he said.

Attorney Chris Carr, who chairs Morrison & Foerster's environmental and energy group, said he expects to see greater interest in emissions regulations and clean energy development at the state level once Trump takes office.

"We also anticipate there will likely be a raucous battle in the federal courts over the legality of strict state requirements, particularly when those requirements implicate interstate commerce," he said in an interview.

California's low-carbon fuel standard, for example, which was created under California's first-in-the-nation global warming law, AB 32, was previously challenged in court by big oil and out-of-state ethanol producers. The Ninth Circuit Court of Appeals in 2013 upheld the standard, which will reduce the amount of carbon pollution released from fuels sold in California by 10 percent by 2020. A year later, the US Supreme Court today denied petitions from these industry groups to review and reverse the appeals court's decision.

"Ultimately, those who believe their interests adversely effected by California emissions regulation can be expected to try to mount court challenges, whether those regulations involve fuel supply mix, shipping and fleet requirements, or engine standards," Carr said. "Once the vacancy is filled on the US Supreme Court, one should also expect renewed efforts to get the court to review the Ninth Circuit's jurisprudence that has so far blessed California's actions.

Biogas Unit for the Home

Jetson GreenJetson Green

cycle2

An Israeli startup has designed a biogas unit, which is small enough for personal use. It is capable of converting organic waste into gas and organic liquid fertilizer. The unit is called HomeBiogas device and looks pretty awesome.

cycle

The HomeBiogas unit can produce 5 to 8 liters of fertilizers and sufficient gas for 2-4 hours of cooking per day. What's more, the unit can also accept and convert dairy and meat, which is generally not recommended to be composted in the home. It can also take in 15 liters per day of animal manure, including pet waste, another substance not recommended for home composting.

sideview

This unit is primarily aimed at the suburban homeowners market as well as small home, off-grid, and eco-living enthusiasts. According to the developers 2.2 lbs (1 kg) of food waste can on average yield roughly 7 cubic feet (200 liters) of gas. To put it in perspective, this is enough for cooking on a high flame for one hour. So a daily input of 13.2 lbs (6 kg) of organic waste yields enough gas for meal preparation, while it also allows the household to get rid of a ton of organic waste per year, which offsets about 6 tons of CO2 annually, which would have been generated otherwise.

A HomeBiogas unit measures 48"x65"x39.4" (123cm/165cm/100cm) and can easily fit in most backyards or greenhouses. It weighs about 88lbs (44kg) so it can be moved around without much trouble. According to the company, they are easy to operate, and require very little maintenance. Though, to use the biogas the units produce on a normal stove at least one of the burners needs to be converted to accept it.

The company is currently raising funds though a crowdfunding campaign, so that they can begin full scale production. Backers can get a unit for a pledge of $890, while the full retail price will be $1500.

How to Make Biogas in 5 Easy Steps – #Renewable #Energy

MOTHER EARTH NEWS...The microscopic organisms that produce biogas, known as Archaea, are among the oldest life forms on Earth. They predate the planet's oxygen atmosphere — much less oxygen-breathing and CO2-absorbing plant life — by a cool 3.5 billion years. That's billion with a "B." Archaea are not bacteria, they are genetically closer to humans and other animals (eukaryotes), and form their own animal kingdom. As the Earth's atmosphere became predominantly oxygen about 500 million years ago, archaea became isolated in the few remaining airless places, such as stagnant swamps, deep oceans, caves and hot springs, and of course the stomachs of vertebrates. To create biogas, we must recreate the conditions in which Archaea thrive in nature.

5 Steps to Making Homemade Biogas

The following table outlines the five steps to creating flammable biogas and I will get into further detail with each one. Biogas is reproduced in a special airtight tank called an anaerobic digester. The design of the anaerobic digester determines the first three steps.

How To Make Homemade Biogas 

Step 1. Airtight Environment. A Ziploc baggie can be used for an anaerobic digester. The difficulty arises from trying to add fresh material without allowing oxygen into the system. The most common method of creating a continuous flow digester is the "teapot" or "P-trap" shape. Most biogas digesters are some variation of this teapot shape.

Homemade Biogas Gas Storage 

Step 2. Archaea love water. When loading a digester, the water content in the material put in it should be taken into consideration. A head of lettuce, for example, looks very solid to us, however, it is 98% water. Dried rice is only 14% water. Regardless of the size of your digester, the "40-50-10 Rule" is simple rule of thumb to follow to get the correct volume: Forty percent material, fill the rest of the digester with water except for 10% headspace.

Home Biogas Digester Contents 

Step 3. A good analogy to think about regarding temperature and anaerobic digestion is your temperature is like the gas pedal of your car. The more you step on it, the faster your digester will convert waste into gas. However, also just like stepping on the gas pedal, there are consequences for it. The warmer your digester is, the archaea that decompose your waste get more fragile and susceptible to an unexpected crash.

Home Biogas Generator Chart 

Temperature can be controlled a few different ways. In China, digesters are typically buried underground and built much larger than they need to be. This way they can be overloaded in winter months to maintain consistent gas production. Other designs employ a greenhouses or hoop house over them. More advanced systems integrate some kind of heat exchanger, which can be heated with solar collectors. Regardless of your design, avoid using biogas or any other fuel to heat your digester. Make sure energy you use is excess energy on its way to being wasted.

Step 4. Neutral pH is an important parameter in anaerobic digestion, just as it is for aerobic composting. If pH is measured at the inlet, it will be slightly lower than neutral — usually around 5.5 — as fresh material is converted into acids. The pH will neutralize as these acids are converted into methane gas. By the time the liquid biofertilizer comes out the digester, it should be 7. If the pH of the biofertilizer is lower than this, it is an indicator the digester has been over-fed and is at risk to "sour," or stop working due to low pH. If the pH at the inlet goes below 5.5, it is necessary to add some wood ashes or lime to buffer the digester. A soured digester has no bubble activity and instead of producing gas, instead it draws air into it. The top will be sucked in tightly against the surface of the liquid and if a brewer's airlock is being used, the water in the airlock will be sucked into the digester. Restarting a soured digester is time consuming, and in most cases it is simpler to dump it out and start over. 

Step 5. Biogas production is best at the same 25:1 C:N ratio as aerobic composting. The reason cattle manure is far and away the most common feedstock for biogas is cattle manure is naturally the perfect 25:1 carbon-to-nitrogen ratio. Cattle manure makes an excellent feedstock to begin experimenting with biogas with. Other wastes need to be combined as a compost pile is.

Best Biogas Materials Chart

After these five steps, it is important to know that for the first 48 hours for a small digester or up to a couple of weeks for a larger system, the digester will only produce carbon dioxide (CO2). Carbon dioxide is of course used in fire extinguishers. When you put a match to the gas to test for flammability, it will be blown out with an audible "hiss" and a wisp of black smoke. As the biogas begins to come on, the hiss and black smoke will be gone and you will smell the distinct "rotten eggs" scent of the hydrogen sulfide (H2S). This odor is the signal to begin capturing your gas, as it is either flammable or soon will be. This "CO2 Phase" has caused many people to abandon DIY projects that might have been flammable if they had waited a short time longer.

World’s First Carbon Neutral Poo Power Plant

World's First Carbon Neutral Poo Power Plant: Officials in the California community of Victor Valley on Friday unveiled the United States' first carbon-neutral wastewater treatment plant. Biogas produced from food waste and sewage powers the plant while keeping tons of garbage out of landfills. Officials at the Victor Valley Wastewater Reclamation Authority expect the system to operate independent of the power grid by 2015, diverting more than 1,400 tons of waste from the trash heap. "Why would we not want to recover the inherent energy in our waste to power this facility so that we're out of that Edison cycle of 'Well, here's your rate increase, here's your rate increase' every year?" Logan Olds, general manager of the high desert city, told the Daily Press.

From poop to power in California

Take Part - Officials in the California community of Victor Valley on Friday unveiled the United States' first carbon-neutral waste water treatment plant. Biogas produced from food waste and sewage powers the plant while keeping tons of garbage out of landfills.

Officials at the Victor Valley Wastewater Reclamation Authority expect the system to operate independent of the power grid by 2015, diverting more than 1,400 tons of waste from the trash heap.

"Why would we not want to recover the inherent energy in our waste to power this facility so that we're out of that Edison cycle of 'Well, here's your rate increase, here's your rate increase' every year?" Logan Olds, general manager of the high desert city, told the Daily Press. "It's a demonstration project and has not been done anywhere else. There are currently no other installations of this technology in the U.S." 

Called the Omnivore Biogas Renewable Energy Project, the system uses co-digestion technology provided by Ontario, Canada–based energy group Anaergia, which was able to retrofit three older digesters already on the plant.

The new system mixes high solids (such as solid food) with sludge (sewage) and uses anaerobic digestion technology to convert the waste into biogas. That biogas, which used to be burned and released into the atmosphere, is harnessed and turned into low-carbon fuel.

cryptogon.com » German Village Produces 500% of Its Energy from Renewable Sources

InhabitatWildpoldsried, a Bavarian village of about 2,600 residents, is leading the way in Germany's extraordinary renewable energy transformation. Over the past 17 years, the village has invested in a holistic range of renewable energy projects that include 4,983 kWp of photovoltaics, five biogas facilities, 11 wind turbines and a hydropower system. As a result, the village has gone beyond energy independence – and it now produces 500% more energy than it needs and profits from sales of the surplus power back to the grid.

RT via @Sustainablog - Coffee Processing Wastewater: a Great Source of Energy

SustainablogWhat do you do with your coffee waste? You may add the grounds to your compost bin, or put them directly onto your roses and other plants as a fertilizer. If you're in the business of coffee processing, though, you're dealing with much more waste… particularly wastewater. According to Dutch sustainable agriculture non-profit UTZ Certified, every cup of coffee we drink requires 140 litres (nearly 40 gallons) of water to process. After that water's used, it's full of organic material. If it simply gets discharged into other water sources, as it often does in the developing world, it's not only polluting water and putting wildlife and people at risk, but it's also creating methane emissions.

Not exactly the kind of guilt you want to deal with first thing in the morning, right? Of course, the people living near these facilities don't want their water dirtied up, either. UTZ Certified has been experimenting with a system that not only cleans up the water, but turns the methane into biogas that can be used by the facility, local farmers, and other nearby residents. After four years of testing in nineteen pilot sites around Central America, the organization has released its results… and they look good. Among the findings:

  • The wastewater treatment was able to dispose of 80-90% of water contamination;
  • Biogas production helped reduce firewood use for local communities, or, in the case of the largest facilities, power portions of the processing machinery;
  • Carbon emissions were decreased by 8-9 tons per community because of the shift away from firewood.

Not bad for initial efforts to deal with these environmental issues.  The experiment was als0 able to cut the amount of water needed for processing in half.

Needless to say, UTZ Certified feels pretty good about these findings, and is now introducing the technology into Peru and Brazil. With more funding, the organization would love to take the wastewater treatment system to coffee producing and processing regions in Africa and Asia.

No doubt, developing world coffee producers need the first shot at this technology: their options for fresh water are often limited. But I'd love to consider the potential for coffee processing here in the developed world, too… no doubt there's wastewater coming from our facilities that could be put to productive use.

Thoughts? Ideas? Share them with us in the comments.

Replacing coal with biogas #renewable #energy

RNE has a look at some CEFC programs to increase the use of biogas in Australia - Major beef processor turns to biogas to halve power bills.
One of Australia's largest meat processors – and a major regional employer, providing 830 jobs – is among the latest recipients of funding from the Clean Energy Finance Corporation, in a deal to co-finance a major on-site energy project at northern NSW-based Bindaree Beef.

The CEFC announced on Tuesday it would provide up to $15 million, together with additional bank finance and an Australian Government Clean Technology Investment Program grant, to fund the installation of a biodigester and energy efficient rendering facilities to improve the efficiency and competitiveness of operations at Bindaree Beef.

As well as the biodigester, the funding will go towards development of an electricity generation facility using biogas (produced by the biodigester) as fuel, and a new more energy efficient rendering plant to replace the existing coal-fired plant and eliminate the use of coal. Screen Shot 2014-07-22 at 10.37.13 AM

The new equipment is expected to halve the company's power bills and cut its annual carbon emissions by three quarters. The biogas plant will also create a new business revenue stream through sales of organic fertiliser – a by-product of the energy conversion process.

Bindaree Beef Director John Newton said securing finance from the CEFC – a $10 billion Labor government initiative, which remains on the Abbott government's chopping block – had been integral to securing the interest of additional private finance, which, along with the government grant, would cover the total project cost. ...

In March this year, the CEFC contributed $20 million to a funding deal with Quantum Power Limited – Australia's leading biogas company – to catalyse up to $40 million in biogas infrastructure aimed at helping farmers and manufacturers cut costs and boost productivity in the face of rising electricity prices.

Forging a path for #Biogas #Energy in Alberta, decade-long adventure into the somewhat unchartered waters of Canadian renewable energy.

hazmatmag.com/ There was a time not long ago when Stefan Michalski knew regulators were happy to see him leave their office. As much as they supported the concept of biogas and green energy, it was more of a technology left to the Germanys of the world, from where Michalski hails, not the wilds of Alberta.

Lethbridge Biogas LP

But now, more Stefan Michalskis are coming out of the woodwork, looking for answers from Canadian regulators, particularly in Alberta, where the feedstock-laden landscape is an anaerobic digester's dream.

Still, the question remains whether provincial officials will eventually craft legislation that deals directly with the burgeoning technology of biogas, or continue what Michalski calls a "one-off" approach—a kind of regulatory patchwork that pulls heavily from the traditional oil and gas sector, one that in some ways operates completely antithetical to the greener principles of a company like Lethbridge Biogas LP, Michalski's decade-long adventure into the somewhat unchartered waters of Canadian renewable energy.

From Poop to Pump for Half the Cost of Conventional Biogas

Whether you're turning lead into gold or farts into fuel, taking something that has no value and transforming it into the very thing that makes your economy run has been the dream of philosophers, alchemists, and scientists since humanity first started thinking of stuff. Recently, Spain launched an initiative to do just that- but the costs have been excessive.

Enter: the Green Cross Method.

This new method is being developed on a farm located just outside of Moscow, and is currently being used to process the manure and methane from about 200 cows into a commercially viable biogas. Derek Markham, over at our sister site, Ecopreneurist, has more on the story, below. Enjoy!

 

New Method Converts Manure to Biogas at Half the Cost

New Method Converts Manure to Biogas at Half the Cost (via Ecopreneurist)

One of the key pieces in building systems that are more sustainable is the idea of using waste as a resource, especially those waste products that aren't avoidable. It's one thing to reduce the amount of waste that gets produced from processes,…

Brookfield Wisconsin to generate electricity from sewage

With help from a $500,000 grant, city of Brookfield officials are crafting plans to use the biogas that comes from sewage to generate electricity for its wastewater treatment plant, the Fox River Water Pollution Control Center.

"We have to burn the biogas anyway to get rid of it, so now we're using it instead of wasting it," Public Works Director Thomas Grisa said. "We're being green in two ways — economically and environmentally.

The grant, accepted by the city's Water and Sewer Board on Dec. 10, is part of Focus on Energy's Renewable Energy Competitive Incentive Program, which is meant to encourage municipalities, schools, farms and companies to install renewable energy systems.

When the system is complete, by the summer of 2015, the biogas will be used in two ways. It will heat the plant's sewage digesters, which would otherwise need to be heated by natural gas, saving about $41,000 per year. It also will be burned to produce about 2 million kilowatt hours of electricity per year, saving about $164,000 annually. For perspective, the plant used about 7 million kilowatt hours last year.

Zero Waste #Energy breaks ground on organic waste to CNG fuel facility

Zero Waste Energy, LLC (ZWE) broke ground on an anaerobic digestion facility in South San Francisco, CA that will convert organic waste into compressed natural gas (CNG) and compost. The Blue Line Biogenic CNG facility will convert 11,200 TPY of food and green waste into 100,000+ diesel equivalent gallons of CNG fuel. The company estimates that each collection vehicle will gather enough organic waste during just one route to fuel it for an entire day, creating a closed-loop system.

The facility is scheduled to commence operation in the second quarter of 2014.

The Blue Line Biogenic CNG Facility is being developed in a partnership with Blue Line Transfer Inc., South San Francisco Scavenger Co., Inc., and Zero Waste Energy, LLC.

The project addresses numerous AB 32 requirements, diverting almost 95% of the organic waste feedstock from landfills. The project will include a SMARTFERM anaerobic digestion facility with 8 dry digesters that will transform 11,200 tons of food and green waste per year into compressed natural gas (CNG), produce 60 kW of electric power and heat to run the facility, an in-vessel composting system that will mitigate odor issues and provide digestate that will be matured into compost.

SMARTFERM is an advanced dry anaerobic digestion system that processes organic waste feedstocks and generates renewable energy. SMARTFERM systems can include biogas-processing technology for combined heat and power (CHP) generation as well as compressed natural gas (CNG). In addition, in-vessel composting options can provide partial or complete maturing of compost for the wholesale or retail market. SMARTFERM facilities can process 4,000 TPY to 100,000 TPY of almost any organic material.

State ruling keeps solar incentives suspended for rest of year

From  Thomas Content of the Journal Sentinel

Solar electric and solar hot water incentives for Wisconsin homes have been suspended for the remainder of the year by the Focus on Energy program.

Focus kept in place a temporary suspension announced in August, after the state Public Service Commission voted 2-1 not to change its stance on making funding for solar contingent on funds being allocated to more cost-effective bioenergy projects.

Renewable energy advocates and businesses had weighed in since then, with hundreds of letters asking the PSC to change its stance to allow more funding for solar energy projects.

In a notice posted on the Focus website, the statewide energy efficiency and renewable energy program said the PSC's decision "forces Focus on Energy to suspend incentives for Solar Thermal and Solar Photovoltaic technologies under the Residential Renewables and New Homes Programs for the remainder of 2013."

Funding remains for residential geothermal energy projects, Focus on Energy said.

Funding for solar projects has been criticized by the Republican majority on the state Public Service Commission is not cost-effective enough, in essence not a wise use of utility ratepayers' money that funds Focus.

The commission capped renewable energy projects at $10 million a year, and decided that funding for solar and wind projects be capped at 25% of funding. Because these projects are contingent on slower-to-develop bioenergy projects, and no more bioenergy funds have been spent, solar is now capped.

This marks the second time in three years that Focus has suspended solar energy funding. In 2011 the commission decided to halt renewables incentives because too much money was being spent on that and not enough on more cost-effective energy efficiency projects.

"No similar situation exists today," said PSC commissioner Eric Callisto, a Democrat, in a critique of the decision. "The commission's decision creates uncertainty in the renewables marketplace and penalizes entire classes of technologies without any compelling justification."

Businesses looking to add renewable energy systems will be able to submit applications under a request for proposals that will be posted on Tuesday on the Focus website, said Sarah Platt, Focus spokeswoman.

That request for proposals will be open to all kinds of renewable energy technologies, though Focus has in the past budgeted smaller incentives for solar and wind, a maximum incentive of $100,000, compared with a maximum of $200,000 for geothermal and $500,000 for biogas and biomass projects.

Wind Power Makes Hydrogen for German Gas Grid

Proposals to generate hydrogen using excess wind power have been blowing around for quite a few years now, with the hydrogen being a form of "energy storage" that can be subsequently burnt for heat and/or power.

Some systems are now appearing in the wild in countries as diverse as Morocco, Turkey, Argentina and Norway.

Greentech media reports that the Germans are getting in on the act as well, converting excess wind power to hydrogen and feeding it into the natural gas grid (perhaps the combination of hydrogen derived gas and biogas will eventually eliminate European dependence on gas from Russia and the middle east) - Wind Power Makes Hydrogen for German Gas Grid

For the first time on an industrial scale, hydrogen produced using wind power is being injected into the natural gas grid in Germany. It's a development that could enhance the value of wind power by making it useful no matter when it is produced.

E.ON said the P2G unit in Falkenhagen in eastern Germany, operated in a partnership with Swissgas AG, has a capacity of 2 megawatts and can pump out 360 cubic meters of hydrogen every hour. In a sign of the potential of the technology, its inauguration drew a crowd that included the German economics minister, members of the European parliament and high officials of Brandenburg state.

"One of the biggest challenges of transforming Germany's energy system is finding ways to integrate the increasing share of intermittent, renewable-source energy," Economics Minister Philipp Rösler said in the E.ON news release. "To ensure that Germany's power system remains stable and that our economy continues to have the energy it needs, we not only have to rapidly expand energy networks. We also need innovative solutions like the P2G unit here in Falkenhagen."

The Falkenhagen facility is essentially a way to store wind power. Instead of turning off the turbines at a nearby wind farm when demand is low (as it can be at night, when the wind tends to blow strongest), or using the power to move water up a hill (effective but site-specific and expensive pumped hydro) or charge a battery (expensive), or try to find a buyer for the power far away (requiring costly transmission), the power is used to turn water into hydrogen by electrolysis. The hydrogen is then shot straight into the area's natural gas system, displacing a fossil fuel.

What's especially interesting here is that last step: the use of the hydrogen in the natural gas pipeline. We recently reported on a study commissioned by the U.S. Department of Energy, "Blending Hydrogen Into Natural Gas Pipeline Networks: A Review of Key Issues," in which the authors sound a fairly optimistic note about the possibility of putting the country's extensive gas pipeline system to work for clean hydrogen's benefit. They don't give a 100 percent endorsement of the idea -- because of the nature of hydrogen, the natural gas system can only take small percentages without extensive reworking -- but their review of the issues says that the pluses appeared significant enough to warrant further study. So while the E.ON project in Germany is fairly small, it should provide valuable insight that will help guide subsequent approaches with the technology.

Other similar approaches include putting hydrogen produced from excess renewables to work in fuel cells, and reacting it with CO2 from bioenergy plants to produce a carbon neutral methane, sometimes known as "renewable methane" or synthetic methane. This synthetic methane could go directly into the natural gas pipeline without the limitations of hydrogen. A 25-kilowatt demonstration plant using just such a system is operating in Germany.

Free Webinar June 11th: Colony Collapse Disorder and What’s Being Done to Protect our Pollinators?

The decline of bees is getting global attention as we risk losing the ecosystem services these important pollinators provide.   On April 29, it was announced that the European Union will enforce the world's first near continent-wide ban on widely used insecticides found to present an unacceptable risk to bees when properly applying the precautionary principle.

Walter Haefeker, a beekeeper in Bavaria serving as the President of the European Professional Bee Keepers Association helped lead the European beekeeping community's efforts to support the EU Commission's proposal to restrict the use of 3 neonicotinoids (clothianidin, imidacloprid and thiametoxam) for seed treatment, soil application (granulate) and foliar treatment on bee attractive plants and cereals.

During this Webinar, Walter will speak about critical issues facing bees today including diseases, pesticides, genetically modified crops and intensive agricultural practices.  He will share his experience working in coordination with environmental NGOs and family farmers organizations towards more bee-friendly friendly production of food, textiles and energy. He will discuss the successful "Fair Milk" campaign where Walter worked together with independent German dairy farmers to use bee friendly methods of feed production and land management. He will also provide insights into a new cooperation with the German Biogas Producers organization to replace corn with flowering plants to produce renewable energy and honey while promoting biodiversity and regenerating soil. Finally, Walter will introduce a new international label developed and owned by the beekeeping community, which is designed to mobilize consumer demand for certified bee-friendly production.
