Global demand for meat, milk and eggs has tripled in the past four decades and is expected to double by 2050. Increased global livestock production has great impacts on the environment and increases global warming. A major new European research project at the University of Copenhagen aims to identify and develop innovative solutions and technologies to handle and utilise the huge quantities of animal waste from livestock production. In Denmark, 34 million tons of animal manure are produced annually. Livestock production in agriculture requires enormous inputs of resources such as land, energy, water and nutrients. New research and innovation will pave the way for the development of technologies and systems to make agriculture more resource-efficient. The principal coordinator for the major new European research project ReUseWaste, Professor Lars Stoumann Jensen from the Department of Agriculture and Ecology at the Faculty of Sciences, explains:
"The ambition of the research project is to generate new knowledge that can help agriculture to contribute to a much more resource-efficient society. The demand for resources is rapidly increasing at the global scale, so we urgently need to think innovatively in order to ensure sustainable agricultural production in the future - it will be absolutely critical for the food and energy security at the global level."
The research project will focus on extracting bio-energy from waste in order to reduce consumption of fossil energy, increasing the recycling of nutrients in order to decrease the use of artificial fertilisers and conserving soil quality by returning organic matter to agricultural land.
In Denmark, 34 million tons of animal manure are produced annually. The project will concentrate on these three focus areas, nutrients, energy and organic matter in agricultural production.
"We believe that these three parameters are key to increasing sustainability," says Lars Stoumann Jense. "As an example, manufacture of artificial fertilisers is extremely energy-intensive and one of the nutrients involved, phosphorus, is a limited resource. By developing technologies for recycling, we can obtain multiple benefits. The ambition is to create a great deal of new knowledge and to develop sustainable technologies that will make agriculture more resource-efficient."
