Japanese industrial and engineering firm, Hitachi Zosen Corp., has designed a system to use waste heat from a waste to energy plant to desalinate water.
According to a report by the Nikkei Asian Review the system has been targeted at the water-scarce Middle Eastern nations.
The system was said to generate potable water using distillation or reverse osmosis –two alternative technologies used in desalination facilities.
The report said that when used with distillation based desalination plant the system uses heat from a waste to energy plant to generate steam from seawater and spin a turbine.
According to the Nikkei Asian Review applied to a reverse osmosis plant the turbines generate electricity to power the process.
I was claimed that 1 tonne of waste generates 600 kWh of electricity or roughly 100 tonnes of.water.
Hitachi Zosen was reported be ready to market versions use one or both processes and the construction of such a plant would cost around the same as building to both separate pieces of infrastructure.
An international competition to design a 5000 tonne per day waste to energy plant in Shenzhen, China – the largest in the world – has been won by a pair of Danish architect firms, Gottlieb Paludan Architects and Schmidt Hammer Lassen Architects.

A five month test program to capture carbon emissions from the municipality operated Klemetsrud waste to energy plant in Oslo, is being undertaken by Aker Solutions, a Norwegian supplier of products, systems and services to the oil and gas industry.
Danish waste to energy technology manufacturer, Babcock & Wilcox Vølund, has been awarded a contract for more than $90 million to design, manufacture and build a waste to energy power plant near Haresfield, Gloucestershire, UK.
