The polyvinyl chloride debate: Why PVC remains a problematic material

Polyvinyl chloride production is associated with the use and generation of chemicals of concern.9 The final product is nearly 60% chlorine by weight.10 The chlorine is obtained through an energy-intensive process that splits sodium chloride (NaCl) from seawater or brackish underground water into chlorine gas and caustic soda (sodium hydroxide

Poly-Vinyl Chloride - Toxic Enforcement ¡ª As You Sow

PVC production results in the creation of several highly toxic chemicals including dioxin, ethylene dichloride, and vinyl chloride. These can cause severe health problems, including: cancer, endocrine disruption, endometriosis, neurological damage, birth defects, impaired child development, and reproductive and immune system damage.

Toxic Pollutants from Plastic Waste- A Review

Incineration of plastic waste in an open field is a major source of air pollution. Most of the times, the Municipal Solid Waste containing about 12% of plastics is burnt, releasing toxic gases like Dioxins, Furans, Mercury and Polychlorinated Biphenyls into the atmosphere. Further, burning of Poly Vinyl Chloride liberates hazardous halogens and
