Cambi awarded contracts in Beijing


28th May 2015

Beijing Drainage Construction Company Ltd has awarded Cambi three new major contracts for the Cambi Thermal Hydrolysis Process (CambiTHP™). These follow contracts for Beijing’s two largest wastewater treatment plants, Gaobeidian and Xiaohongmen.

The new contracts are for three Cambi Thermal Hydrolysis Plants to be built at the Qinghe II and the Huaifang Water Reclamation Plants, and at a new greenfield sludge center at Gaontun. All plants will be owned and operated by the Beijing Drainage Group.

When all these five sludge plants are operating, approximately 1,200 metric tons dry solids a day will be treated by CambiTHP™ in Beijing, serving 20 million people.

The three new projects are for sludge treatment centers. Qinghe II Wastewater Reclamation Plant is located in North and Northeast areas of Beijing. The Qinghe II treatment center will have a capacity of 163 metric tons dry solids a day. The Huaifang WRP will import sludge from several plants nearby and cover part of the South and Southwest areas of Beijing. The Huaifang WRP will have a capacity of 244 metric tons dry solids a day. The Gaoantun sludge treatment center will be the largest Cambi plant built to date, with a capacity of 367 metric tons dry solids a day. The majority of the sludge to be processed at Gaoantun will be imported from four other plants nearby in the East and Northeast areas of Beijing.

Cambi’s Chief Executive Officer Atila Mellilo states that the CambiTHP™ technology will help Beijing and China on their way to achieve a highly efficient and robust sludge treatment with huge environmental and economic benefits.

By using CambiTHP™ advanced digestion, the plants will achieve sludge stabilization with optimal organic degradation and biogas production. The massive sludge volume reduction cuts sludge handling costs significantly. The final product, which is Class-A fertilizer for direct land application, gives a safe and efficient recycling of bio-resources back to land.

Shi Lei, General Manager, Beijing Drainage Construction Company Ltd, expresses: “Over the past years, we reviewed many competing technologies and found Cambi’s to be most technologically advanced, most economical, and more importantly, the most ecological solution for sludge management.”

Beijing Drainage Construction Company Ltd is the leading provider of process turnkey solutions, design, and engineering services for wastewater treatment plants in China.

Cambi is the leading provider of technologies for conversion of biodegradable material to renewable energy and valuable bio-fertilizer resources, based on its patented thermal hydrolysis process (CambiTHP™).
