ABSTRACT
Engineering properties of materials includes friction coefficient and these properties are basic in design performance of various systems. This paper presents estimate of friction coefficient of municipal solid waste components. The components of the municipal solid waste include paper, plastic, organic and others. The friction coefficient is very important in design of handling tool for optimal design. Various types of handling tools and equipment are designed to be used at various stages of disposal and treatment of Municipal Solid Waste (MSW) and friction coefficient is one critical property. The estimation of the coefficient of friction of municipal solid waste was done using an inclino-tribometer. Waste from 16 sample locations were used with 6 different surfaces which are presumed to be of relevant in waste disposal systems. Site specific method was used in waste classification. It was estimated that Formica surface has the least coefficient of friction values and range from 0.269 and 0.312 with ?others? ? formica surface tribosystem being the least. It was also found out that painting a wooden surface with oil paint would increase friction as compared to painting the same wooden surface with emulsion. The study pointed out that polishing with vanish is the best way to reduce friction in wood surfaces. It was observed that painting metal surfaces with oil paint will increase the friction than when the same metal was left unpolished or unpainted.
