What is Bioenergy?
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.
So, Why do we produce Bioenergy?
One reason governments
: 당질계, 전분질(녹말)계 바이오매스
Ex) 사탕수수, 고구마, 옥수수, 콩 등
- 식량으로 사용할 수 없는 리그닌, 셀룰로오스, 헤미셀룰로오스를 포함하고 있는 목질계 바이오매스
Ex) 나무, 볏짚, 기타 농임산 폐기물
Biomass energy 기술: Biomass로부터 생산된 원료(Feed-stock)로부터 석유에서 는 기술
2. 2. Extraction
After the fermentation, the microorganisms(Alcaligenes latus) are filled with PHB in their body. These PHBs have to be separated from microorganisms to make final product. To separate PHBs from biomass, they are extracted from biomass by using solvent. These PHB extracted solvent will experience washing and drying process. After that, PHB can be precipitated as white powder.
The process of removing carbon from the atmosphere and depositing it in a reservoir.
Geo-engineering technique for long-term storage of carbon dioxide or other forms of carbon to either mitigate or defer global warming.
Way to slow the atmospheric and marine accumulation of greenhouse gases, which are released by burning fossil fuels.

2) 바이오 연료
바이오 연료(Biofuel)는 바이오매스(Biomass)로부터 얻는 연료로 살이 있는 유기체뿐 아니라 동물의 배설물 등 대사활동에 의한 부산물을 모두 포함한다. 바이오 연료는 화석연료와는 다른 신재생 에너지이다. 대중에게는 주로 바이오 연료는 바이오알코올과 바이오디젤을 합해 지칭하는 말
