It describes the problems from the depletion of primary material resources, the role and current level of
Waste management encompasses a multidisciplinary approach that integrates engineering principles, economics, urban and regional planning, management techniques, and social sciences. Its objective is to minimize the overall wastage within the system under consideration. A systematic waste management approach should address
The digital image processing technology has been widely used in many scopes such as solid waste management, food engineering, environment and medical care and so on []. The secret of selecting image processing in this work rather than another related technology like machine learning, deep learning is since the input image, SWB,
Solid-waste management - Collection, Recycling, Disposal: Proper solid-waste collection is important for the protection of public health, safety, and environmental quality. It is a labour-intensive activity, accounting for approximately three-quarters of the total cost of solid-waste management. Public employees are often assigned to the task,
This document discusses various material separation and processing techniques used in waste management. It begins with an introduction to waste separation and its purposes. It then outlines different separation processes like picking, screening, magnetic separation, air classification, optical separation, eddy current methods, and
Volume reduction is a type of waste processing where the nature of the waste is altered physically. It is one of the essential steps in waste management system. Proper waste processing will improve the efficiency of solid waste management, facilitate recovery of resources and energy conversion. Volume reduction is defined as handling or

Municipal Solid Waste (MSW) Processing. Municipal solid waste (MSW), also known as trash or garbage, is non-hazardous refuse generated by households, institutions, hospitals, and businesses. It comprises waste, compostable, and recyclable materials, with the municipality overseeing its disposal.
The extent to which MSW is pre-treated and processed before thermal processing or WTE incineration depends on factors such as the inherent requirements of the post-processing technology, local regulations, cost of landfill dumping and MSW composition, and in general pre-treatment may not be globally advantageous. 5.2.

An incinerator can be used for both concepts in MSW management, either processing or disposal of solid waste. Regardless of the incinerator''s construction or intended use, the by-product of the incinerator must eventually be disposed of in a landfill. Landfilling is regarded as an effective method of waste management.
Technologies based on the thermal decomposition (pyrolysis) of MSW can be considered as innovative alternatives to the direct combustion of MSW (Sipra et al., 2018; Jahiral et al., 2022).
