Techniques of Waste Heat Recovery Waste heat recovery is being more used more and more often today as it is becoming more effective‚ due to increasing energy prices‚ technological developments and a decrease in equipment costs. Heat recovery can be classified into three main strategies: recycling energy back into the process‚ recovering the energy for other onsite use and using it to generate electricity in combined heat and power systems. Once the system has been made as efficient as possible before

world‚ different kinds of waste were produced continuously. In the early years‚ the common wastes produced were biodegradable. There are no major problems with this since it will decompose over time. As the number of population increases and new inventions were made‚ the kind of waste produced by humans also increases. Some of these wastes include plastics‚ glass‚ metal‚ papers and many more. Some of waste scattered in the surroundings are recyclable. But due to improper waste management‚ these are not
