Material recovery facility , material reclamation facility , material recycling facility or multi reuse facility ( MRF , pronounced "murf") is a specialized plant that receives, separates and prepares recyclable materials for marketing to end-user producers. Generally, there are two different types: clean and dirty material recovery facilities.

Membersihkan MRF
A clean MRF receives recycled recycled materials that have been separated at the source from municipal waste generated by residential or commercial sources. There are various clean MRFs. The most common is a single stream in which all recyclable materials are mixed, or double flow MRF, in which separable recyclable sources are delivered in a mixed container stream (usually glass, ferrous metals, aluminum and other non-ferrous metals, PET [No.] and HDPE plastics [No.2]) and a mixed paper flow including corrugated cardboard boxes, newspapers, magazines, office paper and junk mail. Materials are sorted into specifications, then released, shredded, crushed, compacted, or prepared for shipment to market.

Mixed waste treatment facility (MWPF)/MRF Dirty
A mixed waste treatment system, sometimes referred to as a dirty MRF, receives a mixed solid waste stream and then begins to separate the designated recyclable materials through manual and mechanical sorting combinations. Recyclable materials can be further processed as needed to meet the technical specifications set by the final market while the balance of the mixed waste stream is delivered to a disposal facility such as a TPA. Currently, MWPF attracts new interest as a way to address low participation rates for separate source recycling collection systems and prepare fuel and/or raw materials for conversion technology. MWPF can provide people with the opportunity to recycle at a much higher rate than has been demonstrated by roadside or other garbage collection systems. Technological advances make today's MWPF different and, in many ways better, than older versions.
The percentage of residual (recyclable or non-recoverable non-recoverable) material from a properly operated MRF supported by an effective public and educational outreach program shall not exceed 10% of the total weight of the delivered stream and in many cases may be significantly under 5% of gross MRF recovered between 5% and 45% of material entering as recyclable material, then the rest is dumped or disposed of. A dirty MRF can have a higher recovery rate than clean MRF, as it ensures that 100% of the waste stream is sorting through, and can target more material for recovery than it usually can be accommodated by sorting at the source. However, the dirty MRF process results in greater contamination from recycling, especially paper. In addition, facilities that receive mixed solid waste are usually more challenging and more expensive to the site. Operational costs may be higher because they are more labor intensive.
MRF Wet
Around 2004, the new mechanical biological treatment technology started using wet MRFs . It combines a dirty MRF with water, which acts to solidify, separate and clean out the output stream. It also hydrocrushes and dissolves the organic biodegradable in solution to make it suitable for anaerobic digestion.
History
In the United States, the modern MRF began in the 1970s. Peter Karter founded Resource Recovery Systems, Inc. in Branford, Connecticut, "the first material recovery facility (MRF)" in the US.
