The world generates 2.01 billion tonnes of municipal solid waste annually, with at least 33 percent of that—extremely conservatively—not managed in an environmentally safe manner. Worldwide, waste generated per person per day averages 0.74 kilogram but ranges widely, from 0.11 to 4.54 kilograms. Adequate waste disposal or treatment

Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable

1. Introduction. Landfill is a convenient and low-cost method, the most commonly used waste treatment technology, especially in developing countries, in the control of municipal waste (Ren et al., 2022).However, fresh domestic waste usually needs to be stored at the waste transfer stations for 3 ∼ 7 days before landfilling, and a large

Management of municipal solid waste (MSW) in low and middle-income countries remains a challenging and neglected key issue. Especially in urban and peri-urban areas, the household waste often remains uncollected on streets and drains, thereby attracting disease vectors and causing water blockages [1, 2] pared to other waste
