A total of 228 plastic recycling plants have been closed by the Malaysia Government up to January, it has revealed.
Inspection agencies, government officials and the police have visited 405 plastic recycling plants in the country.
Of these, 182 were found to be operating illegally without an operating license, while a further 36 were closed for breaching the terms of their license.
Total fines of RM2.323 million (£432,500) were issued.
Inspections will continue of the plants that are still operating to ensure they keep meeting the rules.
The inspection programme is part of an overall strategy by the Malaysian Government to stop the country becoming a dumping ground for illegal waste.
As part of this it recently repatriated 150 containers of illegal plastic to countries including the UK.
