new Delhi. The rising level of pollution has become a challenge for the whole world. According to a report, seven percent of greenhouse gases emit more due to roads made of concrete. Every country in the world is trying to reduce its level so that the environment can be made safe for future generations. In this series, preparations are being made in Australia to make the world's first waste from industrial waste.
Preparations are underway to build roads in the Australian city of Sydney from coal-fired power plants and waste from industries engaged in steel production. Its purpose is to reduce the level of green gases in the atmosphere from the concrete used in road construction. The University of South Wales and the Cooperative Research Center for Low Carbon Living (CRCLCL) are engaged in preparing guidelines for industries for geopolymer concrete.
Road monitoring for 5 years Stephen Foster, head of the School of Civil and Environmental Engineering, says that the road prepared from industrial waste will be monitored for the next five years. In the beginning 3 to 12 months, its capacity will be known on the basis of which improvements and changes can be made.
Then why not in India? After the construction of industrial waste roads in Australia, now the entire focus is on India, why it is not possible to build such roads here? There are a total of 43,936 industrial units across the country from which about 7 million tonnes of polluted waste comes out. According to an Assocham report 1.4 million tonnes of waste is being generated every day. In this, 10 to 15 percent of the waste is fatal, which is directly affecting the environment and humans.
In 2018, a total of 4.1 billion tonnes of cement were produced in the world, according to a study involving 3.5 billion tonnes of CO-tocarbon emissions in 2018. This led to emission of about 3.5 billion carbon dioxide. According to the researchers, the geopolymer made from coal-fired furnaces emits about 300 kg of carbon dioxide in the production of one ton of cement. At the same time, 900 kg from the cement that is made by mechanization. Carbon dioxide is emitted. Coal technology is also effective in saving electricity. This will save electricity used in an average of two weeks in a house.
Targeting to reduce carbon emissions by 2030, policy makers and environmentalists at the United Nations Climate Change Conference said that by 2030, carbon emissions from cement would have to be reduced by 16 percent. Sydney Mayor Clover Murray says that if the ongoing trial of road construction from Geopolymer is successful, the carbon emission rate will be much lower in the future. He said he was also talking to concrete suppliers to reduce carbon emissions in Sydney to reduce pollution and greenhouse gas emissions during road construction.
