Use of Waste PVC Flex Banner in Building Construction Material

Flex banner have combination of Poly Vinyl Chloride (PVC) and fibres. Flex banners have resistivity to temperature and rain water and have a property to made it possible to develop a wide range of properties in flexible PVC. This has been responsible for the growth of flexible PVC over the years. Unfortunately, used flex banners became a part of municipal solid waste and increase over the years. Waste flex banners contribute carcinogenic materials in leachate. The manufacture, use, and disposal of PVC, causes substantial and unique environmental and human health hazards. Across the world, governments, companies, and scientific organizations have come to recognize the hazards of PVC. PVC Flex Banner are used in large quantity for various advertising purposes. These banners are made in various steps which are Ethylene and Chlorine gas production, Feedstock production, Polymerization, Compounding or Formulation, Moulding. After the manufacturing of flex and their usage, these flex are to be disposed, which is the main problem. As these flex are non-biodegradable and when burnt it emits various harmful gases which is a hazard to the environment. The present research work seek the scope of used flex in building construction material like Bricks. It was found that in burnt clay bricks addition of fly ash did not affected the compressive strength by large difference it increased till the concentration reached to 2.5% and then decreased with the further increase in flex concentration. The bricks made by adding shredded flex showed positive results in increase in the performance.
