GreenTracker| Researchers from the National University of Singapore created a model to assess the possibility of creating biofuel from wastepaper and cardboard. Using exact data from 70 countries, researchers extrapolated their assumptions into an additional 100 countries.
The scientists concluded that around 83 billion litres of ethanol could be produced from waste paper, replacing 5% of the world’s global petrol demand. In addition, the wastepaper energy emits fewer greenhouse gases than the same amount of petrol — anywhere from 29 to 86% less. via Cosmos Magazine
