Plastic Texture

Recycling plastic windows

Window frames are made from various materials, probably the biggest competitors
include wood and uPVC - unplasticized polyvinyl chloride, a type of plastic that does
not contain Bisphenol A and phthalates. While some argue that using timber
contributes to deforestation, an extensive study a couple of years ago found
interesting outcomes. When comparing the entire life of different timber frames with
uPVC ones, they discovered that the latter has unquestionably the worst
environmental impact in almost all categories (e.g. human toxicity, global warming,
ozone layer depletion). This is the result of a process in which uPVC is made, mainly
thanks to higher levels of energy consumption. Moreover, this material does not
decompose.


However, vinyl windows are widely used and popular, primarily because of low price
and maintenance requirements. They also have great insulating properties, are
sturdy and durable. As the material does not decay, the best option to avoid
disposing uPVC windows to the landfill is to recycle them. First, the material is
collected and ground into small particles. These can be then separated by colour,
followed by multiple stages of removing impurities, such as metals or silica. The
by-products of this process can be used for other building-related applications.
Lastly, clean granulated material may be further ground into a powder or pelletized
and used for the production of new windows, doors, pipes and so on.


Recycled plastic windows are much more considerate to the environment and
support the circular economy. Reused material serves as a raw material, thus,
prevents consumption of other valuable natural resources. Additionally, recycling
uPVC requires less energy, and as it
