Using only waste as raw materials, NTU scientists have found a way to create biocement, making the alternative to regular cement even greener and more sustainable.<\/p>\n\n\n\n

This biocement is already being used in trials to strengthen the sand on Singapore\u2019s shorelines and to restore rock carvings in China.<\/p>\n\n\n\n

The NTU scientists used two common waste materials, industrial carbide sludge and urea\u2014from the urine of mammals\u2014to create this renewable form of cement.<\/p>\n\n\n\n

When bacteria is added into the mix, and the resulting solution sprayed onto soil or sand, a hardening reaction takes place that binds the soil particles into a solid block.<\/p>\n\n\n\n

The researchers say their biocement can potentially become a sustainable and cost-effective method for soil improvement, reducing dust or wind erosion in the desert, or building freshwater reservoirs on beaches or in the desert.<\/p>\n\n\n\n

A big advantage of the NTU team\u2019s method in formulating biocement is the solution is colourless. When applied to soil, sand or rock, their original colour is preserved.<\/p>\n\n\n\n

This makes it useful for restoring old rock monuments and artifacts. The biocement has been used to restore broken-off pieces, such as the fingers of a Buddha\u2019s hands from the Dazu Rock Carvings, a UNESCO World Heritage Site in China.<\/p>\n\n\n\n

The biocement-making process requires less energy and generates fewer carbon emissions compared to traditional cement production methods. Biocement is produced at room temperature without burning anything, and is thus a greener, less energy demanding, and carbon-neutral process.<\/p>\n","protected":false},"excerpt":{"rendered":"
