Statement of the Problem: Waste recovery is an extremely important operation. It not only makes it possible to reduce the consumption of products of natural origin such as petroleum and metals, but it also makes it possible to limit discharges and emissions in different phases. Therefore, environmental protection and economic growth are at least the two advantages of waste recovery. Methodology & Theoretical Orientation: This work aims at the recovery of hazardous waste by the process of pyrolysis followed by combustion. The transformation of pyrolyzed waste into a usable energy source aims to enhance the economic potential of the waste. A process for pyrolysis of waste and desalination of water and drying of agricultural products has been designed, implemented and tested. Conclusions & significance: The process implemented makes it possible to produce more than 100,000 m3 / day of pure water by Humidification-Dehumidification Desalination process and to dry more than 3,000 kg of solids per day. Natural resources such as oil and gas are replaced by pyrolyzed hazardous waste. This process promotes sustainable development and the circular economy.
