As the fourth type of energy, biomass energy has many advantages: wide distribution, large quantity, being renewable, clean, storable and transportable and so on. By adopting thermo-chemical and biochemical technologies, biomass energy can be converted to high quality solid, liquid and gaseous energy products, and provide convenient heat and power energy for human being’s production and daily life. This paper presented the status quo of biomass power generation industry in China and also introduced briefly the future development models.展开更多

It is a product, process, or activity management system aimed at minimizing environmental and socio-economic burdens associated with an organization＇s product or process during its entire life cycle and value chain. LCM＇s application is gaining wider acceptance both in the corporate and governmental organizations as an approach to reduce ecological footprints and to improve the sustainability of human activities. But where and how can it be used in agricultural engineering applications？ This study highlights the potential areas of LCM application in agricultural and allied sectors and how it can be utilized. The study revealed that LCM tools such as design for environment and life cycle analysis can be used to evaluate the environmental impacts of-and to improve the products, equipment, and structures produced by biosystems engineers as well as the processes used to generate them.展开更多

There are also other challenges such as： low overall level of industry development; not having yet established a complete biomass energy industry system; high production costs; weak market competition; lack of investment in research and technology; low level of market admittance threshold; and disorder of industry development. Therefore, proposed policies aimed at promoting the healthy and rapid development of the biomass energy industry are as follows： improving the policy and regulatory system to enable the biomass energy industry to develop; greater evaluation of biomass energy material resources; accelerating the development of biomass energy conversion and use technologies; establishing the demonstration bases of biomass energy industry.展开更多
