The possibility of complex processing was analyzed and an improved technology of low-temperature pyrolysis of mixed polymer waste (high-density polyethylene 50 % + low-density polyethylene 50 % (HDPE 50 % + LDPE 50 %)) was developed by adding to the main processing technology additional technological processes of processing the received pyrocarbon (production of plastic lubricants and fuel briquettes). The pyrolysis of a mixture of polyethylene waste (HDPE 50 % + LDPE 50 %) according to the basic technology was carried out in a reactor without the access of the air oxygen in the temperature range of 240…395 °С within 3.5 hours. At the same time, pyrolysis products consisted of: pyrolysis liquid — 85.57 % wt., pyrolysis gas — 5.57 % wt. and pyrocarbon — 3.83 % wt. Processing of the obtained pyrocarbon for the purpose of obtaining plastic lubricants was carried out according to the technology, which includes the purification of the used I-40A oil from water and mechanical impurities, its regeneration and mixing with other components: Konstalin-1, polysulfide, oleic acid and a special technological additive (I-40A + BTA 0.1 %) until its complete homogenization. Processing of the obtained pyrocarbon in order to obtain fuel briquettes was carried out according to the technology, which includes obtaining a homogeneous water-colloidal pulp from water and corrugated cardboard and mixing it in a reactor-disperser with the calculated amount of pyrocarbon and wood sawdust. The formed homogeneous pulp was fed to a mechanical or electromechanical press and fuel briquettes of the RUF type were obtained. The developed and improved technology of polymer waste processing enables more complete and effective use of the generated alternative energy sources of pyrolysis liquid, pyrolysis gas and pyrocarbon.
