One of the most common materials that have affected all areas of human life is plastic. Various polymers nowadays have become indispensable due to their relatively low cost and the large number of products that are made from them. They are relentlessly pushing aside glass, metal, and paper. At the same time, from all waste, plastic is the most convenient and easy to recycle. For example, plastic bottles and bags can be recycled completely. Also, the ability to endlessly send plastic for recycling saves the consumption of oil from which it is originally produced.
We have known plastic glazing for a long time. The windows of the “first wave” were of insufficient quality. They were often installed incorrectly due to little experience in installation. In this regard, many owners of problematic glazing are interested in the issue of disposability. Europe has long studied all the ins and outs of the problem and found a solution: Since plastic isn’t subject to rapid decomposition and significantly pollutes the environment, it should be recycled.
Since there are really few processing plants, and they cannot be found in every locality, the issue of recycling old windows is very acute. Companies involved in the installation of glazing don’t undertake recycling. Therefore, the issue of what to do with the old PVC windows and doors is worth considering in advance.
A radical solution to the problem of polymer waste, according to some experts, is the creation of biodegradable polymers that decompose into substances harmless to animate and inanimate nature. First, polymers were created to withstand environmental influences. Nowadays, the concept has changed: now we need polymers that maintain working characteristics during their usage period (consumption) and then undergo transformations under the influence of environmental factors and are included in the natural process of exchange.
Currently, the problem of recycling polymer waste materials is becoming relevant not only due to environmental protection but also due to the shortage of polymer raw materials. From 1 kg of waste (polyethylene terephthalate, polypropylene, low-density polyethylene, high-density polyethylene), 0.8 kg of secondary raw materials are obtained. The popularity of plastic is explained by its lightness, economy, ease of use. Also, the production of plastic requires 21% less energy than the production of glass.
