Biofuel from waste could cut carbon emissions by 80%
Scientists in Singapore and Switzerland claim that converting the rubbish that fills the world’s landfills into biofuel may be the answer to both the growing energy crisis and to tackling carbon emissions.
New research reveals how replacing petrol with biofuel from processed waste could cut global carbon emissions by 80%.
Biofuels produced from crops have proven controversial because they 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, may offer dramatic emissions savings without the environmental catch.
The team found that 82.93 billion litres of cellulosic ethanol could be produced from the world’s landfill waste and that by substituting petrol with the resulting biofuel, global carbon emissions could be cut by figures ranging from 29.2% to 86.1% for every unit of energy produced.
