Abstract
Overpopulation, industrial activities, construction and demolition and over-consumption of resources are the causes of waste production. Waste production is a major problem that is not only contaminating oceans and land, harming human health and environment but also affecting economy. In order to address these issues different approaches that convert waste into useful products (that are both environmentally and economically beneficial) are used. Waste has long been managed using traditional techniques. Due to their limitations, advance techniques such as pyrolysis, gasification, anaerobic digestion, and hydrothermal processing are used because they break down waste materials more effectively and with fewer emissions. By introducing emerging technologies like membrane separation, microbial electro-synthesis, plasma gasification, microbial electrochemical processing, and chemical recycling push the boundaries of waste management. These methods create a circular economy in addition to conserve resources and lower greenhouse gas emissions. It is clear from comparing the efficiency, influence on the environment, durability from an economic standpoint, and scalability of these various approaches that combining traditional and cutting-edge waste valorization techniques is essential. A circular economy is supported by this integration which opens the door to a more sustainable and profitable future.
Keywords: conventional methods, waste valorization, waste to energy conservation, resource conservation, sustainable waste management, circular economy.
