As Per Customer Requirement |
Our Environment: We care!
We believe that Natural resources like fresh water, clean air and vegetation provide sustenance and a foundation for social and economic development.
We have supported this by not only voluntarily incorporating State of the Art Technologyfor taking care of its polluting sources but also by implementing the ISO 14001:2004EMS. We intend to Protect and conserve the quality of air, land, water and other resources, while fostering economic development & a healthy and safe work environment. To validate its support to resource conservation, MCAL has adopted the practice o f rainwater harvesting to meet its water requirements
The company also practices a zero discharge policy. Effluent is treated & reused in process/irrigation. ZnO and dross is filtered from emissions & molt respectively. Hazardous waste like used oil, sludge, dross and ZnO are dealt by CPCB/MOEF authorized recyclers.
MCAL has acknowledged its environmental obligations by operating over & above the requirements of the Consent to Operate under both the Water (Prevention and Control of Pollution) Act, 1974 and the Air (Prevention and Control of Pollution) Act, 1981 , as well as the Authorization of Hazardous Wastes Management & The Registration of Recyclers under the Hazardous Wastes (Management and Handling) Rules, 2003.
Also, as required under the Environment Protection Act 1986 an Environmental Statement is submitted at the end of every financial year thus facilitating comprehensive look at its industrial operations, which further facilitates understanding of material flows and focus on areas where waste reduction and consequently savings in input costs is possible. |
