Cement, Iron and Steel Sector

Agrinergy has a strong track record in developing CDM projects for the cement sector – a major CO2 emitting industry. CO2 emissions from cement production arise from the calcinations of limestone in the cement kiln (CaCO3-> CaO + CO2) and fossil fuel combustion in the clinker kiln and in process electricity consumption.

Agrinergy has been at the forefront of developing and implementing a variety of projects in this sector: The company has successfully developed a methodology for blended cement production and has registeredprojects covering 15 cement plants.

Agrinergy partnered with the Associated Cement Companies (ACC) and Gujarat Ambuja Cements Limited (GACL), two of the largest cement manufacturers in India, to use the CDM to overcome barriers to increasing the blend of fly ash in cement over 12 plants. Agrinergy has been instrumental to these projects; having developed a new methodology based on an ACC plant, as well as identifying buyers.

Another source of potential projects in the cement sector revolves around waste heat recovery. The kiln gases in the cement manufacturing process can be tapped togenerate electricity through the use of waste heat recovery boilers. In the case of The India Cements Ltd, Agrinergy developed a 7.7MW waste heat recovery unit in its Rassi plant as a CDM. This project was registered as a CDM in January 2007.

As with cement, the iron and steel industry is energy intensive and a major source of CO2 emissions. Agrinergy has worked with a number of iron and steel companies in the SME sector and has assisted them to develop Waste Heat Recovery projects.

These companies are at the forefront of economic development in the rapidly industrialising developing countries – supplying the burgeoning demand for iron and steel in construction, manufacturing and infrastructure. As such, assisting these companies to reduce their CO2 emissions is fundamental to combating global warming and enabling economic development along a less CO2 intensive path.

With Shri Bajrang Power and Ispat Ltd, a sponge iron manufacturer in Chhattisgarh, Agrinergy developed the CDM aspects of a project which utilises the CDM to overcome barriers to electricity generation from waste heat gases. Agrinergy successfully developed the methodology, produced the PDD, developed the monitoring report, ensured issuance and marketed the CERs. By using waste heat gases to generate electricity, rather than coal, the project will reduce over 600,000 tonnes of CO2 emissions up to 2012.
