A new $40 million facility in Tuas South will turn all the rubbish collected from Nanyang Technological University (NTU) into valuable resources like electricity and construction materials.
Launched yesterday by Minister for the Environment and Water Resources Masagos Zulkifli, the facility is supported by the National Research Foundation, National Environment Agency (NEA), Economic Development Board and NTU.
More than 11 tonnes of rubbish a day can be processed at the plant.
Waste materials are shredded, dried and converted into gas and other useful by-products.
This process is called gasification, where organic or fossil fuel-based materials are converted into carbon monoxide, hydrogen and carbon dioxide. As the waste is mixed with biomass charcoal, the furnace turns up the heat to 1,600 deg C.
In comparison, conventional mass burn incinerators operate at around 850 deg C.
The plant may one day be used to process medical and hazardous waste too, as its ability to burn at high temperatures is capable of killing harmful pathogens.
These same high temperatures convert rubbish to synthesis gas, or syngas - which is mostly composed of carbon monoxide and hydrogen.
Syngas can be used to produce electricity, and can also be converted into liquid fuel.
