Vision
Make cement production easier, to, abate!
Problem
Cement, a mix of clinker and gypsum, causes ~7, 8% of CO2 emissions, over half from raw, material decomposition, not just fuel, making it hard, to, abate. Any solution must work at scale worldwide.
Solution
We scale LC3 using calcined clay and crushed limestone; it needs up to 50% less energy and existing technology, matching or beating traditional cement in over 90% of applications.
Potential
Using IIT Delhi's developments, LC3 can replace over 90% of global cement production without compromising performance, suitable for growing economies and easily adopted by developed ones.
Target Beneficiaries
Targets the cement and construction industries: cutting CO2 emissions and production cost, and strongly benefiting developing economies.
Current Users
Commercially produced in 10+ countries. In India, first produced by JK Cement (Rajasthan) and used in projects including Lodha's Palava City, Noida airport, and IIT Delhi's Sonipat campus.
