Wasteless technology for processing of plastic waste and food packaging polymer, which is based on the usage of mechanical recycling as the most environmentally friendly way of plastic waste recycling has been developed. The introduction of various kinds of plastic waste, including plastic packaging waste, into sand cement compositions, allows, on the one hand, to dispose millions of tons of plastic waste and at the same time to reduce the negative impact of the last ones on the environment and humans. On the other hand, it allows substituting expensive fibreboard fibres by substantially cheaper polymeric waste, preserving and improving the properties of concrete mixtures, to which they were administered. The resulting product can be used as filler in a cement-sand mixture, which can significantly improve the physicomechanical, thermal and rheological properties of the product made on the cement-sand based mixtures.
