Global vinyl fruition over 30 million tons per year , and 75 of PVC is order to building applicationsPVC has contributed a signifi placet portion of the benignant macrocosm s burden of persistent toxic pollutants and endocrine-disrupting chemicals - including dioxin and phthalates - that atomic number 18 now u niversally present in the environment and the human population (Greening Divisions ,.45 When its wide life cycle is taken into narration , it becomes appargonnt that this ostensibly innocuous plastic is one of the about environmentally uncertain consumer materials produced . For this reason , HBN is committed to shift the demand of the multi-billion clam building materials market toward PVC-free products and policies (PVC-Free Pipe for Purchasers Report ,90Building MaterialWhile the many problems associated with PVC throughout its lifecycle far outweigh the benefits , the construction industry has been unaw be of its authorized cost and long considered it a cheap genial material Piping , vinyl siding , and vinyl take aback are the largest and most familiar uses of PVC . Roof membranes suck up been a growing area (Update on the Environmental Health ,. 5 . It is also used in electrical cable insulant , conduit , junction boxes , wall coverings , carpet backing window and accession frames , shades and blinds , sho! wer curtains , furniture flues , gutters , down spouts , waterstops , insulate , wink moldings and elsewhere . Fortunately , for each of these uses , there exist a wide range of cost effective alternative materials that ready less of a health hazard to workers and the worldly concern at large (The Economics ,.

2Environmental assessmentPVC is the worst plastic from an environmental health perspective posing major hazards in its manufacture , product life and disposal (Greening Divisions ,. 6 . Toxic Manufacturing Byproducts acknowledge Dioxin (the most potent carcinogen known , ethylene dichloride and vinyl chloride are unavoidably created in production of PVC and can father severe hea lth problems , including (The Economics ,. 7CancerEndocrine disruptionEndometriosisNeurological damageBirth defects impaired pip-squeak developmentReproductive and tolerant system damageIn the US , PVC is manufactured predominantly near low-income communities in Texas and Louisiana . The toxic impact of befoulment from these factories on these communities has made them a focus in the environmental judge movement . Dioxin s impact doesn t stop there . As a persistent bioaccumulative toxin (PBT , it does not breakdown rapidly and travels roughly the bollock , accumulating in fatty tissue and concentrating as it goes up the provender chain . Dioxins from Louisiana manufacturing plants migrate on the winds and revolve around in Great Lakes fish (PVC-Free Pipe for Purchasers Report ,. 78 . Dioxins are even found in hazardous concentrations in the tissues of whales and arctic bears and in Inuit mother s breast milk .
