Heat utilization is one of the biggest wins for any industry. And big industries waste much heat from the water, gas, and other sources. Research focuses on optimizing the wasted heat in industry and making it reusable for further uses. This utilizes the wasted heat and ensures that folds increase the productivity of the overall industry. Moreover, limiting the usage of energy impacts less in the environment less. The heat generated from the wasted washing or dyeing water is stored and run through copper pipes to a tank. Several pipes are inserted inside the tank to maintain cold water flow. The cold water passing through the lines will regain the heat of the default dyeing water inside the tank, which will heat the cold water. This assures the saving of heating appliances and wasted water and ensures the utilization of wastewater in an ETP plant to a great extent. To ensure the validity, practicality, and full proof of the research, Quality function deployment (QFD), Functional Decomposition, Black Box, Cluster Diagram, and apparent surveys among the most prominent and most renowned industrialists have been implemented. The best of the materials through a proper testing test, observation, and validation have been selected; all the selected materials and method implementations are of verified reliability. The equipment can also withstand the environmental conditions in which it is used. More or less, 80% of the efficiency is ensured through the process, and the amount of waste throughout the operation is less than 5%.
