Management of organic waste is a major dilemma for developing countries. It generates unpleasant odors and helps rats, flies, bugs and mosquitoes multiply and spread diseases. As it decomposes, organic waste generates methane, a gas that contributes significantly to global warming. Last year Daniel Hoornweg, Perinaz Bhada-Tata and Chris Kennedy predicted in an article in the magazine Nature that the global rate of solid waste generation is expected to triple by 2100. This is bad news because if the investment for solid waste management in developing countries remains as low as it is today, the world is at risk of irreversible environmental deterioration.
