Bayer Material Science Pvt Ltd has approached the Environment and Forests Ministry for environmental clearance to its expansion plans of its unit at Semmakuppam in Tamil Nadu\'s Cuddalore district.

In a letter to the ministry, the company said it wants to increase the production of thermoplastic polyurethane from 210 MTPM to 500 MTPM. It also wanted to install a system house for formulation of polyol blend with a capacity of 1500 MTPM which is used to produce cellular and non-cellular foams.

The total land area is 7.62 acres. The company said it will require Rs 800 lakh for the thermoplastic production enhancement project and Rs 2500 lakh for the formulation of polyol blend project.

The land area of the company is located in the \"special and hazardous industrial use zone\" as approved by the Housing and Urban Development department of the Tamil Nadu government.

The company said there are no historical places, archaeological sites, ancient monuments, wildlife sanctuaries or national parks within a 10 km radius from the project site.

The power requirement is 800 KVA and the water requirement is 97 cubic m daily.

The company said it concentrates on maintaining the greenbelt area, water pollution control, environmental monitoring and occupational health among other things.

The company said there is no chance of emission during addition of second line and for system house it is only a blending and no air pollutant is released.

The main noise generating sources are DG sets. The company said the impact of noise emission from the DG set is minimised by acoustic enclosures and the noise levels are limited to below 85 dB (A).

The generated waste water will be treated in the existing effluent treatment plant and ZLD implementation is under progress and it will be completed before May 2012.

According to the company, parameters like PM2.5, PM10, SO2 and NO2 are analysed twice in a week throughout the study period of 12 weeks for ambient air quality data collection.
