Description
Common waste HDPE plastics include shampoo bottles, plastic pipes, rigid plastic bags, etc. The treatment process represented by this dataset includes shredding, washing, dewatering, feeding, and melt extrusion granulation of waste HDPE plastics. The heating process uses electric heating. No dleaning agent is used during washing. The washing and cooling water are recycled after sedimentation in a settling tank, and the sludge from the settling tank is periodically removed and transported by the sanitation department. Activated carbon is used to adsorb volatile organic compounds emitted during the production process, while particulate matter generated during production is collected and released into the atmosphere. Spent activated carbon, waste lubricating oil, and waste filters are treated as hazardous waste and handled by qualified enterprises; non-utilizable solid waste generated from this process is sold to scrap recycling companies.
Activity Description
This dataset represents the process of producing recycled plastic pellets by high-temperature melting of waste HDPE plastic. It includes energy and auxiliary material consumption, waste generation, and atmospheric pollutant emissions during the production of recycled plastic pellets.
Process Description
Waste HDPE plastic is crushed, cleaned, and dried, then mixed with plasticizers and melted at high temperature to produce recycled HDPE plastic pellets.
