Co-processing in cement industry as a preferential mechanism

April 8, 2016
How the Indian government is making a strong push through policy

The Indian government has made significant changes to its policy on hazardous waste as part of efforts to encourage re-use and safe disposal of hazardous waste (HW) – an effort that can be attributed in part to IIP, the Cement Manufacturers Association (CMA) of India, cement companies, and a specially-organized Forum of Regulators.

The new rules for hazardous waste, which were announced by the Indian Ministry for Environment, Forests and Climate Change this month, are designed to ensure that re-use and disposal of HW occur in an environmentally-friendly manner.

Co-processing of hazardous waste – with the end goal of turning it into resources or recovering energy – is stated to be a preferential mechanism over disposal in the new rules. The government has also banned the import of certain types of hazardous wastes, streamlined processes, and declared it will set up new recycling centers to facilitate the reuse of materials.

IIP Executive Director, Jigar V. Shah, says IIP, CMA, cement companies and the Forum of Regulators convened by IIP and CMA, played a key role in influencing the government to adopt the new rules.

“India is the second-largest cement producer in the world. There is a major untapped opportunity for co-processing that can help save fossil fuel and mitigate greenhouse gas emissions,” he said.

In December 2014, the Forum of Regulators published a compendium of five white papers on AFR use in cement manufacture. These papers outlined how the Hazardous Waste Management Rules 1989 needed to be amended to include co-processing in cement plants as a disposal option; set out technical guidelines for setting up environmentally-sound pre-processing facilities to prepare homogenous waste mixes suitable for co-processing in cement kilns; developed emission standards for co-processing in cement kilns; and presented guidelines for the transport and storage of hazardous waste.
