Bioenergy is the making of fuel from living organisms such as plants, animals, and microorganisms. Wooden furniture, crops, food waste, used fried oil and animal waste are some examples and can be applied which is a great advantage.

City garbage and sewage, marine life biomass and others of such nature are also researched for use as renewable energy sources. It is said that Carbon dioxide which is generated out during the decomposition process is almost as same as burning them.

For converting energy from biomass, there are basically two technologies that currently exist. The known technology is a method called direct combustion reaction which is a method that directly burns biomass to get heat. Also, there are biological conversion methods such as pyrolysis, high-pressure liquefaction, and gasification. Thus, this is the method for us to be able to gain biogas, bioethanol, biodiesel, methanol, hydrogen and more from the biomass.

In the case of Sweden, a bioenergy trade association (SVEBIO) has been established and focuses its development on bioenergy for vehicles. Each year, 25% of its R&D budget is reinvested for this field. Sweden uses 18% of its energy source from bioenergy. Sweden used to have plenty of natural resources. However, with a lack of fossil fuel, Sweden took strong policy to develop the domestic market for bioenergy.

The food waste generated by Koreans is far more than one can imagine. According to the MBC news today magazine, 15,000 tons of food waste is thrown out every day. And on an average 150,000KRW is spent per ton for processing this waste either by disposing of them in landfills or recycling them. Annually anywhere between 8 hundred billion to 1 trillion Korean Won for just processing food waste is spent. If we use this food waste in a productive way, we can obtain natural gas and thermal energy. Furthermore, the remains of processed food waste can be used as either fertilizers or feed of animals. These days, Chung Ju and Busan are places that actually have facilities for processing bioenergy from food waste. It is believed that taking advantage of this valuable bioenergy will reduce fossil fuel.

The Korean domestic bioenergy is still developing. However, it is foreseen that with continuous research and development, and good policymaking by the government and efforts, the industrialization of this energy source would be readily available to consumers.
