Contract Awarded for Anyang Sewage Treatment Plant Project

Posco E&C, one of South Korea's largest EPC Turnkey contractors, has awarded Cambi (Norway) a contract for a Cambi B12 Thermal Hydrolysis Process plant (CambiTHP TM ) for the Anyang Sewage Treatment and co-digestion Project. The CambiTHP TM system will treat all the sludge from a new underground wastewater treatment plant serving 700,000 people in the municipality of Anyang, one of 15 satellite cities surrounding Seoul, the capital of South Korea.

The CambiTHP TM system is designed for a maximum capacity of 84 metric dry tons per day, and will co-digest about 27,000 dry tons of organic waste per year, of which 65 per cent is sewage sludge and 35 food waste. The biogas produced from the co-digestion plant will be turned into renewable energy, both as green electricity and as heat for the CambiTHP TM and digestion processes. The remaining high dry solids dewatered product after digestion will be dried and blended with millet grass to produce a renewable biomass fuel for co-firing in existing power plants. Due to the CambiTHP TM pre-treatment the biosolids is also pathogen free (Class-A) with low odour. It is therefore safe to handle by operators and can be land-applied as back-up to the co- firing solution.

The contract represents a major breakthrough for Cambi in South Korea. Cambi is proud of taking part in a project that not only solves a sludge problem, but also utilises food waste as a source for producing renewable energy.

Mr. Lim, Site Manager of POSCO E&C Anyang Bagdal, expresses that POSCO E&C expects a substantial sludge reduction and increased biogas production from the installation of CambiTHP TM technology. He strongly believes that the first THP project in Korea will be successfully executed through mutual cooperation between Cambi and POSCO E&C.

Cambi's chief executive officer Atila Mellilo welcomes POSCO's decision: "This greenfield project represents a unique opportunity to demonstrate in South Korea the full range of benefits provided by the CambiTHP TM system. In addition to operational and environmental benefits, the fact that the plant is located underground allows the Municipality of Anyang to benefit from a small footprint and substantial savings in capital expenditures associated with the construction of digesters. Cambi is proud to be part of this project and is fully committed to its success."
