If cars ran on household waste

Imagine if cars ran on household waste, if gas tanks were filled with ethanol made from wood chips. Well, the technology to make it happen is already a reality and companies are now racing to bring this kind of fuel to a gas pump near you.

With the right processing, ethanol can be produced from pretty much any form of organic matter. Cellulosic ethanol is made from the cellulose found in waste materials like wood chips and the non-edible parts of food crops, or from purpose-grown grasses such as switchgrass and miscanthus.

These grasses can be grown on land unsuitable for food production, meaning they're not in competition with food crops, and the whole plant can be used to produce fuel, making them a more efficient use of land than traditional biofuels. read more
