Recyclers match their MRFs to the size and style of the local market.
A materials recovery facility (MRF) serving a growing Texas city does not necessarily have a lot in common with one serving a seasonal resort region in Colorado.
In an operations workshop at Recycling Today’s June Recycling Conferences entitled “Tale of Three MRFs,” attendees gained insight into the considerations that went into the design of three very different MRFs.
The people of Summit County, Colo., who live in a Rocky Mountain ski resort area, voted to fund a residential recycling program in a county with just 30,000 year-round residents.
According to Kevin Berg of the county’s solid waste and recycling agency, the voter-approved funding allowed his agency to site 30-yard collection roll-offs throughout the county and build a 10,500-square foot MRF.
The collection bins accept OCC, ONP, mixed paper, steel and aluminum cans, #1 and #2 plastic bottles and glass containers. Materials are kept separate. “We mix very little; we really want to keep things separated,” says Berg.
The MRF features a tip floor and a Nexgen two-ram baler that is tasked with quickly preparing incoming material for shipment. “We do very little storage,” notes Berg, “and we can’t afford to play the market.”
In East Syracuse, N.Y., Mark Naef and Naef Recycling are trying to keep a dual-stream system in place at the company’s 48,000-square foot MRF.
With haulers encouraging single-stream collection however, his company has been faced with the need to do more paper sorting than it would prefer.
A team of eight sorters and a star-screen help Naef Recycling produce an ONP grade that is often shipped loose to an AbitibiBowater mill in Ontario.
A steel-belted conveyor leads bottles and cans past another dozen sorting employees. Glass is run through a trommel screen and crushed and eventually emerges clean enough to be shipped to bottle-making plants.
Naef Recycling’s Logemann Brothers Co. baler produces one-ton bales of OCC, aluminum and steel, while its plastic bales weigh in at around 1,700 pounds. “It’s an older machine, but we love the way it works.
There are not so many older machines to see at the El Paso, Texas, MRF that has just been built by Friedman Recycling. The company’s Morris Friedman detailed how the MRF was built after the company secured a 15-year contract to process the curbside materials collected through El Paso’s new program.
El Paso introduced its program in 2007, going from virtually no residential collection to providing 96-gallon containers to most households. The program accepts OCC, mixed paper, ONP, #1 and #2 plastic, aluminum and steel cans, but not glass.
A Bollegraaf system at the 55,000 square foot MRF features a variety of single-stream sorting and conveying equipment, including a drum feeder, double-deck screens, magnets and eddy currents and an air system.
Crediting an aggressive public education campaign, the facility has been inundated with material from the start and is now processing some 200 tons per day from the city’s homes. “The citizens of El Paso really embraced this program,” said Friedman.
Recycling Today’s 2008 June Conferences were held at the Hyatt Regency O’Hare June 22-24. Next year’s Conferences will be June 7-9 in Atlanta.
