In the industry, 50% of the produced waste heat is low-temperature heat which is usually released to the environment. Re-use of this residual heat is often not economically viable due to the low Carnot efficiency. With the pressing importance of climate action in our industry in mind, the ALTA GROUP was able to develop several technologies to convert the low-temperature waste heat into high temperature heat, electricity or refrigeration, supported by an attractive business model. This way, businesses can contribute to climate action while still keeping their business model economically viable.
