A revised law on the prevention and control of environmental pollution by solid waste is to take effect on September 1, pledging a gradual ban on solid waste imports.

In order to push for garbage classification, the Central Government will formulate general principles and local governments will make regulations based on local conditions, said the revised law.

It will place construction, agricultural, as well as hazardous wastes under a stricter management system and impose more stringent penalties on offenders.
