Solid Waste Management

The company pursues the policy of three R’s- Recycle, Reduce and Reuse- for managing its waste.

I. Industrial Solid Waste

The company pursues the policy of three R’s -- Recycle, Reduce and Reuse – for managing its waste. Many projects have been implemented for solid waste utilisation.

Some of the plans undertaken for effective solid waste management are:

Power generation from coal rejects fines and middling in AFBC boilers.
Slag generated from blast furnace is 100% reused in cement manufacturing and brick making.
Tailor made sinter plant to utilise 100% mill scale and flue dust generated in mills and blast furnace.
SMS slag after granulation is used for road making.
Fly ash generated is used for brick manufacturing and cement manufacturing.

II. Ash utilisation

A captive brick plant has been established to produce around 4.0 lakh brick products/day for manufacturing of fly ash bricks. All construction activities of the company are done through these fly ash bricks. Measures have already been taken to achieve a level of 100% utilisation of fly ash. The ash is partly used for brick making, ash dyke rising, road and embankment construction, cement manufacturing.

Stock of ash available

III. Bio-degradable Waste

A 3 tonnes/day capacity bio-methanation plant has been installed in association with Bhabha Atomic Research Centre (BARC), Mumbai for bio-gas production.
Bio-degradable waste from residential areas is collected, segregated before feeding in the digester. It is a one-of-its-kind plant in the entire Chhattisgarh.
The vermi-compost plant allows conversion of organic waste to manure by using earthworms. The resultant manure is used for the purpose of gardening.
Paper recycling unit has also been installed by at Angul plant.
