Flex banners made of poly-vinyl chloride are a serious environmental and health hazard. They can cause cancers and infertility.
Municipal authorities and the Pollution Control Board have failed to prevent people from burning flex banners thrown in dustbins and at dump-yards. The city produces lakhs of flex banners as politicians and commercial establishments prefer them for advertising and every street has them.
An engineer and environment activist, who is also member of the AP Environment Connect, says, “Flex banners deliver high-quality digital prints, but they are not bio-degradable and when they burn, they emit toxic fumes that have serious effects on health.” He added, “The toxins released when the flex banners are burnt are carcinogenic. These days there is excessive usage of the flex banners by the politicians. We find them even in villages.”
Recycling post-consumer PVC is difficult because vinyl products are mixtures of PVC and additives.
