Description
Common waste LDPE plastics include plastic bags, agricultural films, and various types of packaging bags. The treatment process represented by this dataset includes shredding, washing, dewatering, and melt extrusion granulation of waste LDPE plastics. Electric heating is used for the heating process. No dleaning agent is used during washing; the washing wastewater is settled in a sedimentation tank and then reused. Sludge from the sedimentation tank is naturally dried and then transported off-site for disposal. Activated carbon is used to adsorb volatile organic compounds emitted during production. Particulate matter generated during production is collected by dust collectors, with fugitive emissions released into the atmosphere. Spent activated carbon and waste filters are treated as hazardous waste and handed over to qualified enterprises for disposal. Dried sludge and sorted waste are transported and treated by environmental sanitation agencies.
Activity Description
This dataset represents the process of producing recycled plastic pellets by high-temperature melting of waste LDPE plastic. It includes energy and auxiliary material consumption, waste generation, and atmospheric pollutant emissions during the production of recycled plastic pellets.
