While optical sorters commonly are used to sort paper in material recovery facilities (MRFs) that handle single-stream commercial material, their use on residential fiber sort lines is increasing for a variety of reasons, according to industry source.
For MSS Inc. in Nashville, Tennessee, contamination is one of the greatest factors to consider when adding optics on the fiber lines of residential MRFs. This is because, Sales Director Felix Hottenstein says, “on the residential side, we’re using it to clean up news or mixed paper, not to sort higher grades.”
Residential MRFs that use MSS optical sorters have two things in common: high volumes and high contamination levels. However, he adds, “You need to have the right volume and material coming in that’s not too contaminated, or else you won’t get a higher grade.”
Optical sorters typically are installed in residential MRFs when they operate at 25 tons to 30 tons per hour with an average material stream composition. If the tonnage is lower, installing an optical sorter isn’t justifiable unless the material is extremely contaminated.
Hottenstein says MSS customers using optical sorters on their residential fiber lines offer three reasons for doing so: improved technology, reduction of manual labor and improved material quality.
Hottenstein says eight hand sorters on a line can make about 400 picks per hour, but optical sorters can make about 2,000 picks in that same time
“The savings on the manual labor is the last reason,” he says of MRF operators objectives when adding optical sorting on their residential fiber lines.
While optical sorters normally are used to sort plastic bottles, MSS can replace the sensor head and reroute the conveyor to sort fiber.
Hawn suggests moving from the VIS-NIR (visible near-infrared) spectroscopy typically found in MRFs to either a SWIR (short-wave infrared) or IR (infrared) spectroscopy to segregate fiber, but he says some suppliers are using IR thermography to sort by grammage (thickness).
“For that technique to work, you need to have control on your infeed material’s temperature and humidity,” he says.
While making the plunge to install an optical sorter on a residential MRF’s fiber line can be intimidating, Hottenstein says the advancing technology makes the justification undeniable.
“I think we made quite a big step in the last two years, especially in the last two to three months,” he says. “It’s a matter of whether you save enough labor to justify it. New specifications and the need for cleaner paper from the China situation may cause more need for optical sorters, especially on the residential side. Bigger machines are more expensive, but you have to do what you have to do. You either have to save money or make money.”
Technologically Advanced Single Stream and Commercial Recycling System
FRESNO, CA (May 31, 2016) – Mid Valley Disposal, a family owned recycling and hauling company, announces the grand re-opening of its Mid Valley Disposal Elm MRF in Fresno, California. Designed and manufactured by San Diego, California-based CP Group, the recycling system processes 35 tons an hour of residential and commercial material. The system start-up was April 26, 2017.
“We are pleased to have partnered with CP Group and reinvested in the San Joaquin Valley,” says Jonathan Kalpakoff, VP of Mid Valley Disposal. “Increased processing capacity and the recovery of more recyclables will help with our commitment to increase diversion for the communities we serve. We selected CP Group because of their commitment to quality and being a California family business like us.”
The original system was installed in 2001 and processed 20 tons an hour. Due to needs for increased capacity and better recovery, Mid Valley turned to CP Group, who supplied all the new processing equipment. The bunkers, silos, baling system and tip floor pit from the original system were reused in the existing building.
“This system includes some of our latest recovery technologies, including glass processing and optical sorting technology,” says Ashley Davis, Director of Sales and Marketing at CP Group. “We are honored to work with Mid Valley on this project and bring this modern facility to Fresno. It is an integral part of the recycling capabilities offered to the county.”
The advanced material recovery facility features three MSS optical sorters. The CIRRUS® FiberMax™ is used to remove film and other contaminants out of the fiber stream, while the two CIRRUS® PlasticMax™ units separate HDPE, PET, and Mixed Plastics. The system also features proprietary CP disc screening technology, including CP’s steel-disc OCCScreen™, Scalping Screens, and Glass Breaker Screens, along with 1 NewScreen™ and 2 CPScreens™. An air drum style glass cleaner is used to remove the lights from the glass. The system recovers cardboard, mixed paper, glass, PET, and both color and natural HDPE.
“Like myself, the Kalpakoff brothers are third generation in the waste industry. It is rewarding to work with another family-owned company and see recycling progress through the generations,” says Davis.
With its fleet of 165 trucks, Mid Valley serves 89,000 households in Fresno and the surrounding counties. The MRF processes recyclables for half of the City of Fresno, and also for 75,000 households from 3rd party haulers in the counties of Madera, Tulare, King, and San Luis Obisbo.
System is Most Modern Recycling Facility in the Country of Argentina
The City of Buenos Aires, in partnership with San Diego-based CP Group, opened the most advanced recycling system in the country of Argentina. The new 10 TPH residential single stream recycling system began running last October in Villa Soldati, a neighborhood of Buenos Aires. Since then it has helped the city achieve its sustainability goals.
“It’s the most modern recycling center in Argentina,” announced the Head of Government of Buenos Aires, Horacio Rodríguez Larreta, at the inauguration of the plant in October 2016. “The city has improved a lot in the separation and treatment of recyclable waste,” he continued. “4 or 5 years ago nothing was separated. Today, this system is recovering 400 tons of dry materials per week, and that amount is expected to double to 800 tons per week in 2019.”
The system features CP separation equipment, including the CPScreen™ for 2D/3D separation, MSS Aladdin™ optical sorter, CP Metering Drum, CP OCCScreen™, and CP Glass Breaker Screen with patented Cam-Discs™.
The recycling system is part of the city’s Green Center, a program involved with recovering recyclable materials and providing education about waste treatment processes and its importance in Buenos Aires.
“Throughout the entire process, the City of Buenos Aires has demonstrated environmental leadership as well as a long term commitment to developing a sustainable solution for capturing the valuable recyclables and diverting them from the landfill,” says Dirk Kantak, International Sales Director for CP Group.“Between the City of Buenos Aires, and our local Distributor (Coinsa Construcciones), we could not have asked for two better partners on this successful project.”
The materials recovery facility (MRF) began running October 2016. During the training and commissioning period, CP Group worked closely with the Spanish-speaking local staff to operate and maintain the MRF.
Allows users to walk through full recycling systems using virtual reality
SAN DIEGO, CA (May 9, 2017) – CP Group, recycling solutions provider and equipment manufacturer based in San Diego, CA, unveil the Virtual MRF today at Waste Expo in New Orleans, LA.
The Virtual MRF is a virtual reality simulation that uses two hand held controls and a virtual reality headset. The simulation allows users to explore every inch of a life-size computer-generated model of a material recovery facility (MRF) in real time.
“This unlike anything that has been done before in our industry,” says Ashley Davis, Director of Sales and Marketing for CP Group. “Our Virtual MRF uses the most cutting-edge tech to provide our customers with a very concrete sense of what their facility will be like before anything is actually built. This technology has a lot of potential, not only for our sales force, but for our engineers, and we’re proud to be the first to bring it into the recycling equipment manufacturing industry.”
CP Group will be running Virtual MRF demonstrations at their booth #3647 throughout Waste Expo, May 9-11.
CP Manufacturing, headquartered in San Diego, CA is proud to celebrate 40 years of supplying equipment and processing solutions to the recycling industry.
“At CP Manufacturing, we’ve always been driven by the simple goal of providing high-performance recycling machinery that last,” says Bob Davis, second generation and owner of CP Manufacturing. “For 40 years, CP has been a pioneer in the recycling industry, and we will continue to drive the industry forward for the next 40.”
CP Manufacturing, a family-owned business, was born out of the scrap metals industry. CP’s sister company, IMS Recycling, was founded in 1954 by Charles M. Davis who invented the world’s first aluminum can flattener in the early 1970’s. Later, the CP2000 Can Flattener revolutionized the scrap industry and helped pioneer the era of recycling.
After the aluminum can had become a common beverage container, CP Manufacturing was formed in 1977 in response to the growing demand for aluminum flatteners and densifiers. Since then, the company has developed dozens of patents and expanded its equipment and solutions portfolio as recycling and waste handling evolved.
In the 1980’s and 1990’s, CP recognized that the trend was turning toward curbside recycling. As the United States and other countries worked to increase the effectiveness of recycling by making it easier for consumers to participate and more cost effective to implement, CP dedicated their research and development efforts to assist in this effort.
Since 2003, CP Manufacturing has acquired several other top recycling equipment manufacturers and solutions providers, including MSS, Inc., Krause Manufacturing, and Advanced MRF. This family of companies, known as CP Group, was founded to provide one-stop-shop turn-key recycling systems for a variety of recycling and waste diversion operations.
Today, CP is an award-winning, industry-recognized provider of some of the largest and most advanced material recovery facilities in operation. CP has built over 450 MRFs worldwide and continues to invest heavily in R&D and automation technology to stay ahead of the changing material streams. And true to its family roots, the company still offers the original can densor product lines.
“We are and always have been a family-owned and operated company,” says Ashley Davis, third-generation family-owner and Sales and Marketing Director of CP Group. “What sets us apart is that we treat our customers like family. Their success is our success. We’re with them for the long haul.”
