Co-generation involves the use of a heat engine or power system to simultaneously generate electricity and useful heat. It is procurement of two forms of energy from one fuel source. It is one of the leading technological advancements for achieving fuel efficiency. Under the right circumstances, power generation systems can achieve 50%-200% gains in efficiency or more over their current setup.

Subsequently, Hima Cement introduced a globally acclaimed co-processing technology that utilises waste to generate fuel. It disposes of more than 100,000 tons of waste per year and reduces carbon dioxide emissions by 67,000 tons. The company is currently using more than 50% of its fuel from biomass and the goal is to reach 80% use of green energy.
