沼气工程存在和发展的必然WHY BIOGAS PLANTS

有机废弃物量大、面广;有些很集中

环保与能源:互为原因,或者此消彼长

Organic Wastes: huge, distributed, sometimes centralized

Env. Vs Enr. Need to be arefully handled

政策的关键作用CRUCIAL ROLE OF POLICIES

中国:政府主导型

政府制定政策(宏观)

重视建设

难以重视管理与运行效果

通过建设沼气工程盈利

China: Derived by governments

Policies but in general

Supporting construction

Difficult to monitor and evaluate

Earning money from biogas construction

欧洲:政府通过市场驱动加以主导

政府制定政策(宏观与可操作性)

建设成果

运行与成果接受市场评价

通过运行沼气工程盈利

EU: Derived by governments through market tools

Policies can be referred to by farmers

Supporting construction and management

Evaluated by market; well tech

Make benefit from management

德国沼气工程技术进入中国的捷径HOW GERMAN TECHNOLOGIES ENTER CHINA

  • 选择具有社会威望的合作伙伴

  • Partners in China: High reputation, Noon-profit.

  • 选择具有经济实力的用户

  • Clients in China: Big enough, capable of total cash investment

  • 进行充分的研究,掌握原料、气候、政策、客户等充分信息,掌握当地沼气工程存在的技术问题

  • Thorough study before taking action, have full information of feedstocks, climate, and local policies, as well as the client; have full information of local biogas plants problems
