Materials recovery facility

A materials recovery facility, materials reclamation facility, materials recycling facility or Multi re-use facility (MRF, pronounced "murf") is a specialized plant that receives, separates and prepares recyclable materials for marketing to end-user manufacturers. Generally, there are two different types: clean and dirty materials recovery facilities. In the United States, there are over 300 materials recovery facilities. The total market size is estimated at $6.6B as of 2019. As of 2016, the top 75 were headed by Sims Municipal Recycling out of Brooklyn, New York. Waste Management operated 95 MRF facilities total, with 26 in the top 75. ReCommunity operated 6 in the top 75. Republic Services operated 6 in the top 75. Waste Connections operated 4 in the top 75. In 2018, a survey in the Northeast United States found that the processing cost per ton was$82, versus a value of around $45 per ton. Composition of the ton included 28% mixed paper and 24% old corrugated containers (OCC). Prices for OCC declined into 2019. Three paper mill companies have announced initiatives to use more recycled fiber. Glass recycling is expensive for these facilities, but a study estimated that costs could be cut significantly by investments in improved glass processing. In Texas, Austin and Houston have facilities which have invested glass recycling, built and operated by Balcones Recycling and FCC Environment, respectively. Robots have spread across the industry, helping with sorting. Waste enters a MRF when it is dumped onto the tipping floor by the collection trucks. The materials are then scooped up and placed onto conveyor belts, which transports it to the pre-sorting area. Here, human workers remove some items that are not recyclable, which will either be sent to a landfill or an incinerator. Between 5 and 45% of "dirty" MRF material is recovered. Potential hazards are also removed, such as lithium batteries, propane tanks, and aerosol cans, which can create fires. Materials like plastic bags and hoses, which can entangle the recycling equipment, are also removed.
