Unlike first-generation biofuels from crops like corn, soybeans and potatoes which takes away good arable land ...using biofuels from processed urban waste is a better way to reduce carbon emissions and end fossil fuel dependency, the study states. Countries produce enough waste to reduce their carbon dioxide emissions by up to 80 percent and end their dependence on fossil fuels, states a recent study reported by Red Orbit.
According to a study made by Swiss and Singaporean scientists, processed waste can be a source of second-generation biofuels, production of which does not compete with food.
The study compares data from the United Nation's Human Development Index in computing the waste production of 173 countries and Earthtrends' information on the gasoline consumption of the same countries.
The replacement of gasoline with the biofuel derived from such waste can reduce carbon emissions by 29.2 percent to 86.1 percent per unit of energy generated, the study says.
