Sludge-to-energy Plant Construction
Doosan Heavy Industries announced on August 7 that Doosan Enpure, its subsidiary in the United Kingdom, signed a 30 billion won ($26.55 million) deal with a British water supplier Severn Trent Water Authority to build a sewage sludge-to-energy plant in the country. Sewage sludge refers to the residual, semi-solid material that is produced as a by-product during sewage treatment of industrial or municipal wastewater.
Under the contract, Doosan Enpure plans to build an eco-friendly plant that transforms waste into energy. Utilizing its latest energy technology in heat and pasteurized process, the plant will reduce the amount of sewage sludge and produce bio gas with sludge by-products at the same time and provide some 1 megawatt worth domestic electricity and heat. It will be built in Stoke-on-Trent, Staffordshire, 70 kilometers south from Manchester, England, and the delivery is scheduled in 2019.
An official from Doosan Heavy said, “It is meaningful in that the company is taking part in the sludge-to-energy market which is an eco-friendly new renewable energy sector, beyond the existing seawater desalination and water treatment plant sectors. Based on our technologies and performance in the water treatment projects, we will aggressively target the environmentally friendly water treatment market as well.”
According to water treatment market researcher Global Water Market, the global water treatment market is expected to show an annual growth rate of 3 percent from 880 trillion won (US$778.76 billion) in 2017 to 940 trillion won (US$831.86 billion) in 2020.
