Environmental Protection in Niger Recycling of waste

The refinery in Niger has designed and constructed landfills for solid wastes in accordance with the most advanced standard in China; it treats household garbage through harmless landfill or waste incineration, and hires special recycling companies to deal with recyclable wastes like woods and steel plates. We have also built monitoring sites and monitoring wells around the refinery to monitor changes of atmosphere and water quality.

Soil Restoration by Using Microorganism Repair Technology

To protect the ecological environment where we operate and minimize the impact of our activities on land resources, we have made great efforts in exploring the use of microorganism repair technology in soil restoration and achieved remarkable progress.

Given the local climate and soil conditions, a research team at Jilin Oilfield tested the microbial restoration method using renewable, low-cost materials and screened out a group of microorganisms for high-efficiency hydrocarbon degradation. Follow-up evaluation indicated that after a restorative cycle of eight weeks, the microorganisms could degrade the polluted soil to a degree of above 80%, making it ready for phytoremediation. At Southwest Oil and Gas Field, microorganism repair technology was used in a trial treatment of solid wastes of two old wells, rehabilitating a 2,000 square meters land which was once used as solid wastes pool. Unlike traditional treating methods, the technology can transform harmful substances in wastes into carbon dioxide and water and make the soil cultivable again with the metabolites from microbial growth.

In the years to come, we will continue to develop and improve this technology and promote its wide application.
