Policy support for biogas purification

Untreated biogas has high methane content and low purification cost. This is mainly due to the increase of energy production, and the total cost is related to higher energy level. The cost can be reduced by improving efficiency (reducing energy consumption per unit output) and using raw biogas with high calorific value to reduce actual energy consumption.
