Abstract
Municipal Solid Wastes (MSW) from the city of Boa Esperança, Minas Gerais, Brazil, were used to produce Solid Fuel Pellets (SFP). The MSW contain residues of the human society, including product packaging, bottles, batteries, organic wastes, fines, textile, health textile, plastics, glass, metals, among others. The following protocol was performed during the conversion of MSW in SFP: (i) the raw MSW were placed into a silo and conducted to a primary crusher using a metal conveyor belt, which reduced the particles size to 80 mm; (ii) the biomass was conducted to a selective waste collection platform by a rubber conveyor belt, being the recyclable waste, metals and glasses separated manually; (iii) residual metals were removed by a magnetic separator; (iv) the waste was conducted to a secondary crusher which reduces its particles size to 60 mm; (v) the waste passed through an airborne separator to remove materials with high density, such as: glass, stones and organic using a metallic conveyor belt; (vi) the particle size was reduced to 40 mm by a tertiary crusher; (vii) the non-ferrous metals, especially aluminum, from non-metallic materials, such as: plastic, paper, rubber, among others were separated using an Eddy current separator; (viii) the particle size was reduced to 25 mm using a quaternary crusher; (ix) the MSW was introduced into a rotary dryer using a metal conveyor belt, reducing the moisture content below 15%; (x) the solid fuel was compacted, pelletized and stored for use in thermochemical reactors to produce a combustible gas. In addition, the MSW and SFP were analyzed and the elemental composition and combustion characteristics were determined. On the basis of these results, the protocol evaluated was effective on conversion of MSW in SFP, which can be used as a source of renewable fuel.
