PVC Truths

“There is absolutely no evidence that vinyl damages human health or the environment.
PVC is durable, low maintenance recyclable and performs well in LCA tests”
– Dr Patrick Moore, founding member of Greenpeace (2006)

“We should learn to live with this rather wonderful plastic”
Dr John Emsley, University of Cambridge,

The Truth about PVC
PVC is made up of two main elements
  • Chlorine (57%)
    The non fossil fuel derived content of PVC (approximately 57%) is predominately chlorine, derived from salt (Sodium Chloride), one of the most common materials in the earth’s crust. Chlorine performs many useful functions. For example, it is used to purify water supplies to prevent the spread of disease. Salt itself has an estimated 14,000 uses. It is used for road safety, in agriculture, pharmacology, and it makes chips taste great. Reserves of salt are estimated at 10 million, billion tonnes. Obviously we are unlikely to run out any time soon.
     
  • Fossil Fuel (Oil 43%)
    The fossil fuel content of PVC-U is approximately 43%. When oil is refined it can yield a number of useful chemicals, one of which is ethylene – the chemical used in the manufacture of PVC. Some have claimed that it takes eight tonnes of oil to make one tonne of PVC, the inference being that the remainder is wasted. Obviously this is untrue.
    Fossil fuel resources are finite. Estimates as to how long they will last vary and frequently change. According to predictions made in the 60s we should have run out by now. Additional deposits keep being discovered and they are being extracted and used more efficiently.
    More important perhaps is that it has been demonstrated that ethylene can be derived from renewable organic feedstocks.
