A Material Recovery Facility (MRF) is a building to receive, sort, process and store recyclable materials to be shipped and marketed to end-users. A materials recovery facility accepts materials, whether source separated or mixed, and separates, processes and stores them for later use as raw materials for remanufacturing and reprocessing.
The main function of the MRF is to maximize the quantity of recyclables processed, while producing materials that will generate the highest possible revenues in the market. MRFs can also function to process wastes into a feedstock for biological conversion or into a fuel source for the production of energy.
MRFs serve as an intermediate processing step between the collection of recyclable materials from waste generators and the sale of recyclable materials to markets for use in making new products. There are basically four components of a MRF facility: sorting, processing, storage, and load-out.
Any facility design plan should accommodate all these activities which promote efficient and effective operation of a recycling program. MRFs may be publicly owned and operated, publicly owned and privately operated, or privately owned and operated.
There are basically two types of MRFs: dirty and clean. A “dirty” MRF receives mixed waste material that requires labor intense sorting activities to separate recyclables from the mixed waste. A “clean” MRF is a facility that accepts source separated or commingled recyclable materials. A “clean” MRF reduces the potential for material contamination.
Small MRFs (less than 10 tons per day)
Each MRF in operation vary in size and configuration. Most counties, cities and non-profit organizations that operate MRFs are small; less than 10 tons recyclables handled daily and less than 15,000 square feet of building space. Total capital costs to construct the facility could be anywhere between $500,000 and $1,000,000.
The difference in cost is attributed to building materials used, site purchase and preparation, entrance doors and size. Many of these facilities are not highly automated. Manual labor is used instead of sorting equipment. The type of processing equipment is basic, such as a vertical or horizontal baler, forklift, glass crusher, can blower, etc.
Large MRFs (larger than 500 tons per day)
Large facilities operate more than 100 tons per day, are fully operated, often located in very large cities, and often owned and operated by the private sector. Such MRFs are equipped with highly automated equipment in state of the art facilities and may need several millions of dollar to build.
A major cost to consider in planning for a MRF, in addition to land, construction and permitting costs, is the purchasing of equipment to process the recyclables. The equipment needed will depend somewhat on how the material is brought to the facility. If any material is commingled, sorting lines may be needed. However, if all material is source separated, less sophisticated methods for removing contaminants could be used. The following is a list of some of the equipment that would be needed to operate a MRF.
Pre-processed Material Handling Equipment
- Magnetic Separators and Screens
Size Reduction Equipment
- Can Densifier
- Can Flattener
- Glass Crusher
- Plastics Granulator
- Plastics Perforator
Processed Material Handling Equipment
- Skid Steer Loader
- Dust Collection System
- Noise Suppression Devices
- Odor Control System
- Heating, Ventilating, & Air Conditioning (HVAC)
- Fixed Storage Bin
- Floor Scale for Pallet or Bin Loads
- Truck Scale
- Belt Scale
Bee'ah's Material Recovery Facility in Sharjah
Bee’ah’s Material Recovery Facility is the largest in the Middle East and ranks the third largest in the world. This specialized facility sorts and separates recyclable materials from municipal solid waste, through mechanical and manual processes. With an annual capacity of 500,000 tonnes, the MRF is currently processing 900 tonnes of general waste, of which an estimated 60% can be recycled and thus diverted from the landfill. One of the highest contributors has been plastic – including PET and mixed plastic, with a 700% increase from March 2010 to 2011, paper and cardboard second at 366%, followed by a 135% increase in aluminum recycling for the same period.
Very good artilcle and learnt more about MRF.
Thanks & regards

Usually in the bigger plants, automatic sorters are placed to ensure highest purity and production capacity.
¿What does this MRF in Bee’ah do with the organic waste and other non recyclable materials?
Keep on with these articles!
very good article 🙂
“Bee’ah’s Material Recovery Facility in Sharjah is the largest in the Middle East and ranks the third largest in the world.”
That’s great to know, and a great motivator for those of us living in or near the UAE to step up our own recycling efforts.
Excellent write ups. Congratulations to authors.
Thanks for your kind and encouraging words.
Hope you liked other articles on our website also.
Are there any large processing facilities that take baled plastic waste in and discharge viable plastic products out ( decking matrerial, jetty building blocks, railroad ties, buoys, etc., etc,) ? Thanks
