WHAT IS BIOMASS? In the developed world biomass is becoming more important for dual applications such as heat and power generation. Biomass is a clean renewable energy resource derived from the waste of various human and natural activities. It excludes organic material which has been transformed by geological processes into substances such as coal or petroleum.The energy of biomass is extracted from three distinct sources: * Wood * Waste * Alcohol fuels * Crops * Landfill gases | |
Wood is the largest energy source of biomass: contributors include the timber industry, agricultural crops and raw materials from the forest.Waste energy is the second largest source of biomass energy. The main contributors are: municipal solid waste and manufacturing waste.Alcohol fuels is the third largest contributor and is derived mainly from corn.Any source can be used to fuel biomass energy production. We can use rubbish, animal manure, woodchips, seaweed, corn stalks and other wastes. Biomass is matter usually thought of as garbage. Some of the sources are just lying around: dead trees, left-over crops, woodchips, sawdust from lumber mills, even used tires and livestock manure will do.In California, USA, more than 60 million tons of energy sources for biomass energy are collected each year. If all these sources were used to create biomass energy, California could make up to 2000 megawatts of electricity. That is enough to make electricity for about 2 million homes. HOW DOES IT WORK? The harnessing of energy from biological mass (biomass) is a simple process. The waste wood and other sources are gathered in big trucks. The waste is then transported to a biomass plant. Here, the waste is fed into furnaces where it is burned. The heat created is used to boil water and the energy from the steam...
