Bioenergy is a renewable energy made available from materials derived from biological sources. In its most narrow sense it is a synonym to biofuel, which is fuel derived from biological sources. In its broader sense it includes biomass, the biological material used as a biofuel, as well as the social, economic, scientific and technical fields associated with using biological sources for energy. This is a common misconception, as bioenergy is the energy extracted from the biomass, as the biomass is the fuel and the bioenergy is the energy contained in the fuel (source: Wikipedia).
Any form of chemical energy from indirect or direct sunlight is called biomass. The one that includes agricultural products like woods, raw materials can be transform into biomass which leads to bioenergy.
Biomass also includes materials from biotic environment or living organisms which includes plants, animals and their by-products. Manure, garden waste and crop residues are all sources of biomass. Based from the carbon cycle, this is a very good source of renewable energy.
A good example of this is the waste that comes from animals also called as animal manure. This product can be used as fertilizers for plants and would help grow the crops.
There are also agricultural products being grown for biofuel production. These include corn and soybeans and to some extent willow and switchgrass on a pre-commercial research level, primarily in the United States; rapeseed, wheat, sugar beet and willow (15,000 ha in Sweden) primarily in Europe; sugar cane in Brazil; palm oil and miscanthus in Southeast Asia; sorghum and cassava in China; and jatropha in India. Hemp has also been proven to work as a biofuel (source: Wikipedia).
As mentioned from previous articles, biodegradable materials from industrial companies, forestry and agriculture and even through householders are beneficial either directly ir indirectly in producing bio gas or gasification to produce syngas or by direct combustion.
Biodegradable wastes materials as we all know includes manure, rice husks, sewage, straw and food waste (which is very rampant). These can contribute so much too on our waste management along with good source of fuel and helps in preserving our nature and climate change issues.
You can get bioenergy from almost everything, and yes, at the same time help save our environment. There are a lot more benefits that this bioenergy from waste materials can give us. All we need is an open-minded government to help develop this and if campaigns for information dissemination about the benefits of biomass are being distributed, even a simple householder can help save energy and our environment as well.
