Cue for India? Australia conducts world’s first trial to create roads with industrial waste

A brilliant infrastructural initiative to lower pollution levels! Sydney, the most densely populated city in Australia, is conducting the world’s first ever trial to construct roads using industrial waste from the coal-fired power stations as well as steel manufacturing plants.

According to a recent PTI report, this initiative has been taken with an aim to lower the pollution levels and the greenhouse gases emitted during the production of concrete for construction of roads. The concrete contributes around 7 per cent of all greenhouse gas emissions in the atmosphere. In the year 2018, about 4.1 billion tonnes of cement was produced across the world which contributed about 3.5 billion tonnes of carbon dioxide emissions, according to researchers.

Researchers explained that ‘geopolymer’ which is made from fly ash and blast furnace slag, generates just about 300 kilograms of carbon dioxide per tonne of cement, as compared with the 900 kilograms generated from the traditional cement production. Read More
