Biomass energy is produced through the combustion of plant and animal wastes. While being a renewable sources it also pollutes the environment. Some examples of biomass energy sources include, wood such as branches or tree stumps. Waste from paper manufacturing facilities can also be used to produce biomass energy. A variety of other plants that can be burned to produce energy such as hemp, corn sugarcane and bamboo. In Brazil, the eucalyptus plant is burned fro the production of energy. The problem with burning plant crops that are also used for food is that it increases their prices making it expensive to those in developing countries. There has been much ethical debate on this topic of using food crops for biomass energy.
One unique biomass energy production method suggested by a Toronto cattle farmer involves the use of methane. Methane gas is collected from the livestock and is combusted to produce energy for the farm. The farm runs on its own energy and does not need any electricity from the grid to operate. The farm also sells organic turkey which it carries in its meat store. Waste meat and fats is also used to produce energy to sustain the farm operation.
Biomass energy also provides higher incomes to struggling farmers as the value of crops used for energy production are valued higher than food crops. According to the UCSCSA , tripling the use of biomass energy in the United States can provide $20 billion to farmers and reduce global warming. It is important to note that all the byproduct waste from biomass energy is easily disposed of and biodegradable.
