The organization through extensive R & D activities has identified various solid wastes that could be used as productive inputs. The company pursues the policy of three R’s -- Recycle, Reduce and Reuse – to managing its waste. Many innovative projects under “Wealth from Waste” have been implemented for solid waste utilization. The main objective of the company is to transform solid waste into wealth in order to benefit from it.
The Parsada dump yard of JSPL stores solid waste on a temporary basis and then for further re-use, the solid waste is transported to the sinter plant.
Some of the plans undertaken by JSPL to effectively control solid waste are as follows:
- Power is generated from coal rejects, fines and middlings in AFBC boilers.
- Slag generated from blast furnace is 100% reused in cement manufacturing and brick making.
- Tailor made Sinter plant to utilize 100% mill scale and flue dust generated in mills and blast furnace.
- SMS slag is used for road making.
- In order to generate bio-gas from cow dung, two bio-gas plants have been constructed. It is mainly used for cooking and other domestic purposes.
- The Vermi-compost plant allows conversion of organic waste to manure by using earthworms. The resultant manure is used for the purpose of gardening.
- A modern and state-of-the-art health-care centre allows scientific collection of bio-medical waste and its effective disposal to an authorised recycler.
- Captive brick plant to produce around 4.0 lakh brick products/ day for manufacturing of fly ash bricks.
- All construction activities of the company are done through fly ash bricks.
Recently BMP (bio-methanation plant) was installed in association with BARC, Mumbai for bio-gas production. Bio-degradable from residential area is collected, segregated and fed in this 3 TPD BMP. It is the only plant of its kind in whole of Chhattisgarh.
As per the Fly Ash Notification Law, which came into effect from 1999, JSPL has attained Fly Ash Utilisation Status. Steps have already been taken to achieve a level of 100% utilization of the same. The ash is partly used for brick making, ash dyke rising, road and embankment construction, cement manufacturing and land filling.
A separate brick making plant has also been constructed to utilise the fly ash generated from the power plant. The plant capacity of 60,000 bricks on a daily basis has already been met.
