MRF ( Materials Recovery Facility )
A MRF (refer to as materials recovery facility, materials reclamation facility, materials recycling facility or Multi re-use facility) is a place where collected solid wastes are delivered to be sorted into different types (e.g. plastics, cardboard, paper, metal). When the materials are separated and sorted, they will be further shredded, compacted or baled and then sent to reprocessors and manufacturers for creating new products.
The main function of the MRF is to maximize the quantity of recyclables processed so as to reduce the use of new raw materials. MRF typically includes sorting line, baler, shredder, various separation devices like magnetic separation, air classification etc. as well as various conveyors that connect these equipments with each other.
The sorting line is comprised of an in-ground infeed conveyor which transport the solid waste after dumping by truck to a horizontal conveyor where sorting is performed manually by picking out recyclables from the stream of waste on the sorting conveyor.
Shredders are used for large items or organic material. The size-reduced materials have greater surface area to volume ratios, which increases decomposition, air exposure, reducing odors and promoting dryness.
Baling machines are utilized to increase the density of the materials so that the materials can be stored and transported with the highest cost efficiency through the maximization of volume in each load.
