Economic and Environmental Impacts of Biogas

Abstract

Renewable energy resources have been drawing attention in many countries in recent years. One of them is biogas that is particularly important in rural areas. Developed and developing countries and some international organizations headed towards to biogas and other renewable energy sources because of many reasons, such as Renewable, Economic, Environmental Pollution, Global Warming, Greenhouse Effect , and Public Health etc. It is expected that fossil-based energy resources will run out after a short period. Nowadays, efficient of existing resources has not been considered as possible. These have forced to use more efficient and more widespread of renewable energy sources. In biogas systems, all kinds of organic waste have been processed and produced electrical energy in biogas production plants. In addition to the production of biogas electricity, formation of environment and air pollution caused by waste is also reduced to the minimum. Remaining waste of biogas is called bio-fertilizer. It is very efficient plant fertilizer, which is used in sustainable agriculture. Electricity generation from Biogas has been increasing rapidly in recent years. Generated electricity is given to the public power network. Besides, heat that occurred during this process is used to warm the facilities, which are located close to plants, such as greenhouses and housing.
