CLEANTECH is a strategic Enviro-management tool developed by Ashok Sharma, a renowned international expert on clean production technologies, aiming at zero-emission through minor process modifications and low cost innovations, i.e., pollution control beyond compliance levels at profit rather than at cost. The concept focuses on "source reduction" and segregation of effluent streams for in-process recycling, by-product manufacturing or disposal as usable raw material for other processes.Implementation of CLEANTECH helps build up an organizational culture of productivity, efficiency and voluntary compliance providing a competitive edge to the enterprises. It also leads to an easy acquisition of Eco-labels and conformance to ISO 9000 & 14000 environment management systems.
