Hindustan Zinc’s Central Research and Development Laboratory (CRDL) received 6^th CII-Environmental Best Practices Award 2019 under the category – Innovative Environmental Project. The award was presented for CRDL project on ‘Material Conservation – Recovery of Antimony from Slag and Vanadium from Spent Catalyst’ during CII – Environmental Best Practices Award 2019 & GreenCo Summit 2019 events held from 3^rd – 5^th July 2019 at New Delhi.

About 172 case studies were submitted by 72 companies,  out of which 17 case studies were selected through a systematic assessment by independent CII assessors for presentation. The final round was evaluated by five members of CII GreenCo Rating System Assessment Panel.

Material Conservation project was awarded for developing two unique processes for generating value added products from residues and waste:

• Recovery of antimony from lead smelter slag as antimony trioxide of more than 96% purity  
• Recovery of vanadium as ammonium meta vanadate from spent catalyst, a hazardous waste presently disposed off in secured landfills
