Investigation of the effect of municipal solid waste fragmentation to gaseous formation
Abstract
Municipal Solid Waste disintegration and size reduction are often used in the material recovery sector under integrated solid waste management, ie in recycling. Historically, the benefits of size reduction are examined under three headings. The first of these is the separation of the waste pile into the main components of raw municipal solid waste paper, plastic and glass packages to make material recovery and separation more efficient. The second is the reduction of the Municipal Solid Waste fragmentation to an easier size for any equipment or personnel that follows the average grain size. Finally, and most importantly for material recovery facilities, the disintegration process enables automatic material separation processes such as air classifiers, sieves and optical separators by producing different size distributions for different municipal solid waste components. Prior to 1985, the main principle used in the design of a dimension reduction device was focused solely on the application of impact force. The results of such an idea were larger and heavier machines, which led to an increase in capital and operating costs. The composition of municipal solid waste is so diverse that machines designed for municipal solid waste must be strong enough to handle both soft and ductile materials, as well as hard and durable materials such as metals and dense plastics.
