Technical Specification for Pollution Control of Plastic Waste
1 Scope
This Standard specifies the technical requirements for pollution control in the process of plastic
waste generation, collection, transportation, storage, pretreatment, recycling and disposal.
This Standard is applicable to pollution control and environmental management in the process
of plastic waste generation, collection, transportation, storage, pretreatment, recycling and
disposal; and can be used as the technical basis for environmental impact assessment, design of
environmental protection facility, environmental protection acceptance of completion,
pollution discharge permit management, and clean production audit for the plastic waste
recycling and disposal.
This Standard does not apply to degradable plastic wastes.
