Our project, named REHEATZ, wants to recycle heat that is currently wasted during the production and preparation of meat in Zambia. The aim is to reduce the energy, cost and carbon dioxide emissions of food products. Large volumes of hot water are used producing meat and preparing meat-based food. Most of the energy in this hot clean water at 40-50 C is discarded.
We want to recycle that energy instead through the development of wastewater heat recovery technology (WWHR). With WWHR, the energy used to heat the cold water for food service use will be brought back into the local heating system, lowering the cost of food production and reducing energy and carbon dioxide emissions. REHEATZ offers a viable developing country solution for Zambia as it develops low-cost technology for the benefit of the local community.
