| Waste |
| Last year we enhanced the breadth of our reporting by including waste arising from cartridges, tyres and drum. This year we are pleased to report that there has been a remarkable decrease in the consumption of cartridges, tyres and drums. |
|
| The process of reducing of waste cannot survive in isolation. It has to be complemented with a robust process of reusing and recycling. |
|
| Most of our waste is sold to third party contractors for disposal. A large percentage of non-hazardous waste disposed in this manner is eventually recycled or reused. Hazardous waste finds its way to authorised Common Hazardous Waste Collection, Treatment, Storage and Disposal Facilities after which it is incinerated or put in a landfill. |

| Note: The inconsistent increase or decrease in the absolute waste generation is mainly due to the
reasons like: |
| (a) |
Waste disposal is scheduled to optimize transportation cost without compromising on legal compliance especially for drums and containers. |
| (b) |
Useful life of a particular material e.g. Batteries, Cartridges, Oil filters, E-waste, tyres, etc; |
| (c) |
Increase or decrease in the business activities e.g. MWC, MTWL; |
| (d) |
Utilization of Waste generated in one process into another e.g. MLDL uses the solid waste for pavements and reclamations. |
|
| |
| |
Employees were trained in waste identification which resulted in a tremendous improvement in waste sorting. |
|
| |
Reduction of paint & thinner consumption resulted in 7% reduction of hazardous waste generation and a saving of INR 5.2 million |
|
| |
Recycling of flush paints, achieved cost savings of INR123,925/month and reduction of 500 kg/month in paint sludge generation. |
|
| |
Reuse of hazardous waste by converting it into Alternate Fuel helped replace @ 120 tonnes of coal/annum. |
