Positive effect of marine biodiesel for water resource protection

Situation of the serious water resource pollution in our country was introduced in this paper. Current water resource condition can't be able to keep sustainable development especially in water scarcity area just as Beijing and Tianjin. Beijing Jingzhong Sunlight Petrochemical Co. Ltd, located in Beijing, built marine biodiesel demonstration plant with abandoned waste oil as raw material to obtain biodegradable biodiesel which can replace petroleum diesel. The company also built oil plant supply base together with neighboring Inner Mongolia at Bayannaoer region. Biodiesel could play an important part in water resource protection if it was applied to water system for special environmental required river source, wetland and environmental protecting area. Using biodiesel to replace petroleum diesel in water system around Beijing has positive significance in the following three aspects: safeguard the capital for sustainable development, changing waste oil for good and greening subprime land.
