THE TWIN CHALLENGE : TOWERING WASTE VOLUMES ; DWARFING RESOURCES
While our natural resources are fast depleting, another glaring crisis facing our world today is the challenge of disposing the vast quantities of waste generated, in an environmentally friendly and safe manner.
THE PANACEA FOR THE TWIN CHALLENGE: CO-PROCESSING OF WASTE IN CEMENT KILN •Geocycle India provides sustainable waste management solutions through co-processing of waste in cement kilns. • The use of waste as raw material, or as a source
of energy, or both to replace natural mineral resources (material recycling) and fossil fuels such as coal and petroleum (energy recovery) in industrial processes, mainly in energy intensive
industries (EII) such as cement is called coprocessing. •The co-processing of wastes in cement kiln, in addition to the safe disposal of wastes, also decreases the environmental impacts of wastes, reduces greenhouse gas emissions; curtails waste handling costs, and conserves natural resources.
MECHANISM OF WASTE DISPOSAL IN CEMENT KILN •The organic constituents are completely destroyed due to
high temperatures, long residence time and oxidizing conditions in the cement kiln. •Acid gases such as HCL and SO2 are absorbed and neutralized by the freshly formed lime and other alkaline materials within the kiln. •The inorganic constituents reacts with the raw materials while heavy metal becomes immobilized in clinker matrix •Concrete made from cement manufactured using alternative fuels and raw
materials has the same construction and environmental properties as concrete made from cement manufactured using fossil fuels and traditional raw materials .
What do we do in Geocycle?
Waste assessment
Pre-processing
Waste analysis
Waste transportation
Co-processing
CEMENTING A GREEN FUTURE: TRIPLE BOTTOMLINE BENEFITS OF THE INITITATIVE People – •Effective contribution to waste management at local and regional levels. •Regional job creation in waste collection and pre-treatment facilities. •Saving of public funds otherwise needed to build additional incinerators as the infrastructure (cement kilns) is already in place. Planet•Co-processing is a zero residue waste management solution •Cement Kiln co-processing respects waste management hierarchy. It undertakes waste management only after the options of Reduce, Reuse and Recycle are exhausted and avoids the options of resource destruction by way of incineration and containment by way of landfill that do not promote sustainable development. •Co-processing of waste in cement kilns saves precious raw materials and fuels. •Reduces the environmental impacts of the extraction (mining or quarrying), transporting, and processing of raw materials & reduces GHG emissions Prosperity•Substitution of traditional fossil fuels and/or traditional raw materials. •Performance and competitiveness of cement industry is boosted. •Support is provided to regional economic development
