Recycling of plastic waste in paving stones and in ecological houses
Urban and Public Design
Madagascar is famous for its beaches and biodiversity, but it is also famous for its plastic waste. 1,500 tons of household waste are evacuated daily in the capital and 30% of this waste consists of plastic waste. They are one of the most bulky household waste and very slow to degrade so that the community controls it most often through practices that do not respect the environment such as incineration in the open air, burial in the soil which makes the land uncultivable and the chemical elements of its waste reach the water table by their leaching. it is from this that we had the idea of recycling its waste in an ecological way and in order to create jobs for women and young people. Unlike some methods of recycling or disposing of plastic waste by fire, that of the MIHARI-SOA association includes the treatment of smoke released during cooking. The treatment process uses lime as a gas absorber, it filters the emission of toxic fumes at 90%. On this, M’IHARI-SOA then produces paving stones for the construction of alleys and the construction of houses in plastic bottles.
