The Municipal Administration Department has indicated to the National Green Tribunal that dumpyards in 10 urban civic bodies in the State would soon be closed in a scientific manner.

Proposals from private companies have been invited for this purpose. The companies, through appointment of consultants, would be asked to produce detailed project reports for the scientific closure of yards in places including Cuddalore, Poonamalle and Tiruvannamalai.

The information was provided to the NGT in the hearing of cases relating to illegal dumping of garbage on water bodies across the State last week.

The department said latest scientific processes such as use of geo-synthetic liners and polyethylene membranes would be used to close the yards. The reclaimed lands would then be converted to parks and playgrounds.
