A plant manufacturing tiles and blocks from Kota stone slurry was inaugurated in Kota on Sunday.

First of its kind in the country, the plant has been established by the Kota Stone Traders Association with the help of Rajasthan State Pollution Control Board (RSPCB) and Rajasthan Industrial Investment Corporation (RIICO). It will help in gainful utilisation of the Kota stone slurry, which has proved to be an environmental hazard so far.

“The plant will reuse Kota stone slurry. So, it is an eco-friendly plant and will prove to be a milestone in environment conservation, city development and generating employment,” said Gaurav Goyal, the district collector of Kota, while inaugurating the plant.

The plant will manufacture the slurry-based floor and wall tiles, paver blocks and cellulose lightweight concrete (CLC) blocks.

Pashan Welfare Foundation (PWF) direcor Mukesh Kumar Tyagi said that in 2014, the National Green Tribunal (NGT) had imposed a fine of Rs 5 lakh each on a large number of Kota stone traders for improper disposal of the Kota stone slurry. The traders had then assured the tribunal of gainful utilisation of the slurry, after which the NGT had waived off the fines.

Meeting the promise, PWF has set up the plant under the start-up project of Rajasthan government, for which RPSCB has provided free-of-cost technique. Rs 53 lakh has been spent on the project including Rs 13 lakh grants from the RPSCB. RIICO provided 12,537 square metre land for the plant set up in the industrial area of Kota.

“PWF would urge government for using the tiles and other building material manufactured from slurry in government development projects,” Tyagi said.

Amit Kumar Sharma, regional officer, RPSCB, said that the board had carried out a study through Central Building Research Institute of the IIT Roorkee, which later developed and provided the technique to RSPCB. Around 50 Kota stone traders have attached themselves with the slurry project, he said. “The plant has the capacity to manufacture 8,000 flooring tiles, 3,500 rough paver and 5,000 bricks daily from the slurry,” he said.

The products made from the Kota stone slurry are around 30% cheaper than the conventional tiles and blocks. So, RPSCB has written to the state and union government for addition of this slurry-based products in the basic schedule of rates (BSR) of state and central government. “Since Kota Stone slurry is an insulating material, so use of slurry in building construction can also keep the temperature of the constructed building low,” he said.

According to the RSPCB data, around 200 to 250 tonne of Kota stone slurry is generated per day at around 250 Kota stone processing units in Kota city alone.

Earlier, fly ash generated from the Kota Super Thermal Power Station (KSTPS) posed a similar problem till a decade ago. Later, use of the fly ash in manufacturing of bricks and cement transformed it into a profitable business.
