VinyLoop
Open-knowledge reference entry
VinyLoop is a proprietary physical plastic recycling process for polyvinyl chloride (PVC). It is based on dissolution in order to separate PVC from other materials or impurities.
Background
A major factor of the recycling of polyvinyl chloride waste is the purity of the recycled material. In most composite materials, PVC is among several other materials, such as wood, metal, or textile. To make new products from the recycled PVC, it is necessary to separate it from other materials. Traditional recycling methods are not sufficient and expensive because this separation has to be done manually and product by product.
VinyLoop is a recycling process which separates PVC from other materials through a process of dissolution, filtration and separation of contamination. A solvent is used in a closed loop to elute PVC from the waste. This makes it possible to recycle composite structure PVC waste, which would normally be incinerated or put in a landfill site.
Process
The process consists of the following steps:
Pre-treatment: waste plastics are cleaned, ground and mixed
Dissolution: a specific solvent is used to selectively dissolve the PVC compound in a closed loop
Filtration: impurities which have not been dissolved are removed through filtration—they are separated by type of material by filtration, centrifugation and decantation.
“VinyLoop” enters the record as open-knowledge reference entry. Crown Archives preserves that source wording while asking what VinyLoop, Open-knowledge and entry can confirm, complicate or overturn.
Why this record matters
“VinyLoop” is worth following because a concise public description often conceals a longer documentary argument. Here, VinyLoop, Open-knowledge and entry provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 16, 2025. The linked authority identifier is Q906169. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
