A team of scientists have been researching on a new technique where orange peels and newspapers could be used to run your vehicles in the near future. Now it is based on the concept of bio-fuel like using these to produce ethanol as fuel. However the ethanol produced by food causes more CO2 emissions.
This technique not only reduces the CO2 emissions compared to ethanol but it would not require food-based products to produce it unlike bio-fuel. This will benefit cause there are no chances of global food shortages or spiraling food costs.Food-based products are not used for this process such as sugarcane, corn, starch etc. It basically reuses waste products. Although research is still been done to verify the findings.
