Singapore -- Singaporean and Swiss scientists say using trash to produce biofuels might help solve the world's growing energy crisis and also reduce carbon emissions.
The researchers said current biofuels produced from crops require an increase in crop production, which has its own severe environmental costs. However, second-generation biofuels, such as cellulosic ethanol derived from processed urban waste, might offer dramatic emissions savings without the environmental catch.
"Our results suggest that fuel from processed waste biomass, such as paper and cardboard, is a promising clean energy solution," said Associate Professor Hugh
