The North Delhi Municipal Corp is targeting cement companies with an all-India tender inviting industrial units to utilise the RDF recovered from biomining of the Bhalswa Landfill located in the city, according to the Hindustan Times.

The Solid Waste Management rules established in 2016 state that RDF should form at least five per cent of the fuel mix of units that have a landfill within 100km.

"We have a pre-bid meeting for it tomorrow (Tuesday) and will see how many companies from across the country come and decide what the financial dynamics of the project would be," said Varsha Joshi, north corporation commissioner.

While 20,000t of waste has been segregated, there are concerns that the material may need to be transported to states further away. "Delhi-NCR doesn’t have any cement kilns while coal-based thermal power plants here, Badarpur and Indraprastha, have been shut. The nearest cement plants we have are in Kotputli (Rajasthan) and Bilaspur (Himachal Pradesh)," said an official.
