Fate of PVC polymer, plasticizers, and stabilizers
Landfill simulation assays demonstrated the long-term behavior of PVC products and the fate of additives under landfill conditions. The PVC polymer was found to be stable. A loss of plasticizers may occur in case of insufficient compatibility with the PVC compound coupled with microbial consumption at the PVC product surface.
Fate of PVC polymer, plasticizers, and stabilizers
Journal of Vinyl and Additive Technology is a peer-reviewed technical publication for new work in the fields of polymer modifiers and additives, vinyl polymers and selected review papers. Abstract End-of-life PVC products are predominantly disposed of with construction waste or with municipal solid waste in sanitary landfills.

Fate of PVC polymer, plasticizers, and stabilizers
End‐of‐life PVC products are predominantly disposed of with construction waste or with municipal solid waste in sanitary landfills. This waste management option is currently subject to debate because of environmental issues. A material and substance flow analysis was conducted to estimate the quantitative relevance of PVC products and their constituents in municipal solid waste. Landfill
Production, use, and fate of all plastics ever made | Science
Similarly, in 2015, PVC accounted for 11% of nonfiber plastics production (38 Mt) and only 6% of nonfiber plastic waste generation (16 Mt). By the end of 2015, all plastic waste ever generated from primary plastics had reached 5800 Mt, 700 Mt of which were PP&A fibers. There are essentially three different fates for plastic waste.
- Does PVC polymer deteriorate in landfills?
- The PVC products and their additives underwent the characteristic stages of landfill development, being subject to leaching and biodegradation. No degradation of the PVC polymer was observed during the extensive observation period in landfilled waste.
- Are plasticisers released from landfilled PVC products?
- It is uncertain whether plasticisers are released from landfilled PVC products or if they originate from other waste streams. Plasticisers are applied in construction materials and products other than PVC, such as polyurethane (PU) joining foams (BBP, DEHP).
- Should end-of-life PVC products be disposed in sanitary landfills?
- End-of-life PVC products are commonly disposed in sanitary landfills. However, the safety of this disposal method is a subject of debate due to uncertainties and risks associated with landfills and their long-term behavior. Therefore, the fate and potential environmental impact of PVC products and their additives in landfills has been a topic of public discussion.
- Are PVC products harmful to the environment?
- The long-term behavior of PVC products and their additives in landfills is a source of uncertainty and risk. There has been public debate about the possible environmental impact of PVC products degrading into vinyl chloride (VC) in landfills. Landfills are a potential concern for the fate of PVC products.
- What is the fate of flexible PVC compounds and plasticisers (phthalates) in landfills?
- The fate of flexible PVC compounds and plasticisers (phthalates) in landfills is marked with an asterisk *. Possibly relevant contributions of PVC products and their additives to emission patterns are also discussed in the section 'Fate of stabilisers, heavy metals and organotin compounds'.
- Does PVC polymer contribute to the substance inventory in waste?
- The contribution of PVC products to the substance inventory in landfills is determined, followed by a description of the fate of the PVC polymer and its additives. Since the transformation of substances in the landfill body plays a role, potential emissions are discussed.
