Nothing is lost in nature! The production processes produce "clean" energy that can be reused. We have our own ways of doing that.
Recycled energy, is called "clean energy." This is the energy generated by production processes, which is treated as waste and released to the outside world, e.g., in the form of hot exhaust gases. By using technologies allowing for the recovery of this energy, we are able to reuse it. Not only does this offer the opportunity to generate savings, but if this energy is used locally for the plant, it can also contribute to reducing the carbon footprint and CO2 emissions.
