Global waste generation has risen sharply over the past decade. In 2023, the world produced 2.3 billion tons of municipal solid waste, a number projected to reach 3.8 billion tons by 2050. This growth is driven by population increase, urbanization, industrial activity, the rising consumption of goods, and a lack of effective waste management systems. On average, a person generates about 0.74 kg of waste daily, with figures ranging from 0.11 to 4.5 kg. Without proper waste management and recycling, the environmental and economic consequences could be severe. To address this, several technologies now support sustainable waste handling. Material recovery facilities collect and sort waste for recycling using both manual and mechanical methods. Composting and gasification help convert organic waste into valuable products. Robotics and AI are also being integrated for more precise material sorting. Turning waste into energy offers a promising path to sustainability. Municipal and agricultural wastes can be used in anaerobic digestion to extract methane, which is then used for electricity generation. Landfill technologies also contribute to energy recovery in eco-friendly ways. Moreover, waste can be transformed into fertilizers rich in macro-nutrients through solvent extraction techniques. These fertilizers benefit agriculture by providing essential nutrients. Some urban waste is even repurposed for road construction, using recovered plastics and soil-like materials. While these innovations mark progress, further research, and development are crucial to improving resource recovery methods. Advancing these technologies will play a key role in creating a cleaner, more sustainable future.
