OUR APPROACH
Given the tight financial constraints presented by the cement industry Dastur Energy takes a holistic approach that combines the following strategies to maximize business impact while reducing overall carbon intensity of the process.

The type of kilns and energy sources required for cement production result in high CO2 emissions (~0.6 tonne of CO2 per tonne of cement produced).
There are sourcing and compatibility challenges when considering alternative fuels (such as biomass, waste-derived fuels, and non-recyclable plastics).
There is a need to invest in techniques such as – waste heat recovery, use of preheaters and precalciners, and optimizing grinding processes to improve energy efficiencies
Carbon Capture and Storage (CCS) technologies offer a good low-carbon solution, but low operating margins present a key challenge to their financial viability.
Dastur Energy has prepared a techno-economic feasibility report for decarbonization of cement plant with over 95% carbon capture from flue gas for one of the largest cement player in North America.
Feedstock formulation enabled through blending and other preprocessing strategies allows low-cost, low-quality biomass to be blended with higher cost and higher quality to achieve the in-feed specifications at the conversion facility.
