The article presents a project of an innovative technological line for producing stretch foil. The technological innovation consists of the fact that the foil is produced from a material composed of primary raw material and up to 80% recyclate. The new product cannot be used differently from the traditional one, as it is produced 100% from primary raw material. Additionally, recyclate is produced from waste originating mainly from agriculture. The production line includes systems allowing the use of materials contaminated with organic particles without needing a thorough cleaning. Another innovation is the use of low-temperature waste heat in the production process. It comes from the cooling of the first calender roll. Until now, this heat has dissipated in the atmosphere. Low-temperature waste heat was transformed into high-temperature heat and used in the technological process to prepare the raw material. A heat recovery line was designed based on two cascaded, hydraulically coupled compressor heat pumps to transform low-temperature waste heat into high-temperature technological heat. The designed system can be expanded and adapted to current production needs. The developed technological line solves several problems. It helps to manage difficult-to-manage post-production waste from agriculture and other sectors of the economy. It reduces energy consumption and raw materials from non-renewable sources, significantly reducing CO2 and other greenhouse gas emissions. This is in line with the assumptions of the European Green Deal, which implements a circular economy and is based on renewable energy sources. Currently, the technology is being developed and implemented.
