Biomass Solutions For Greener And Cheaper Energy

By Serena Price


Biomass solutions for greener and cheaper energy became more important in the last few years. Although people mostly think about crops and vegetable derived materials, this term applies also to animal derived material. Renewable energy sources are finally recognized and appreciated. The best thing is that these sources will be there as long as people continue growing their food, and these sources can satisfy all people's energy needs.

All kinds of materials can be used to generate this renewable form of energy. This includes all types of agricultural and non-agricultural residues and matter. And so many things usually get wasted, and they could be so easily transformed into a real, live energy. This includes different industry waste as well, for example paper or textile industry waste.

Energy crops is the term used for different types of plants that are grown for biomass production only. Some food plants such as sugar cane, as well as wheat or maize are often used for making bio ethanol or even combustion fuel. All oil crops contain high percentage of oils and are really great for producing bio fuels and similar products.

Non agricultural sources such as forestry by products and different waste and residues created as a by product in specific industries, or even consumer waste, all that can become valuable biomass, and be transformed in some kind of energy. Instead being wasted, all these materials are put into good use once again.

Biomass products, such as bio ethanol, bio fuel and bio gas produce considerably lower quantities of pollutants, and are considered as low carbon fuels. Animal digestion transforms it into methane, and it is used for heating farms, for example. In short, biomass can be used as a source for numerous energy producing materials and become very useful.

Most fossil fuels are expensive. They have to be transported on long distances, and there are limited reserves of all these fuels. They all emit high carbon dioxide levels, especially coal. Coal is still quite cheap, even cheaper than using bio fuels, but really pollutes the air. On the other hand, most crops are grown locally, and easy accessible. The costs are additionally lowered thanks to that.

In process of production of energy, bio fuels and other biomass products emit some carbon dioxide, but in lower concentrations. Besides, this carbon dioxide will be used by plants in the next cycle. The plants will, using sun and photosynthesis, transform this carbon dioxide into valuable nutrients and, in the end, in energy. This means that plants will first absorb it during growth, and than release it in the air again, in never ending cycle. Sustainable growth methods lower the final carbon emission additionally.

Considering the fact that natural gas and oil reserves are limited, biomass solutions become more important. With lower expenses and unlimited supply, this green and renewable energy source is absolutely needed today. The only problem with agricultural waste is that it is seasonal, and reliability of supply is uncertain. This problem is solved using dedicated energy crops such as perennial grasses. These fast growing grasses are easily grown in areas unsuitable for food crops.
