Machinex technology to produce RDF while maximizing recyclate recovery at Scottish power plant

MRF to process 42 tonnes per hour of MSW and commercial & industrial waste

In March 2015 Machinex was appointed by major global engineering and construction company, M+W Group, to provide a Material Recovery Facility (MRF) for the Energy from Waste (EFW) project for Levenseat Renewable Energy Limited in Lanark, Scotland. Last May, Machinex started the installation of this first-of-kind facility and expects the front-end sorting facility should be completed and operational in early 2017. The addition of the drying solution is scheduled to be operational in mid 2017 to complete the project.

The system is an RDF & SRF preparation plant designed to process 42 tonnes per hour of commercial & industrial waste along with municipal solid waste. The Materials Recovery Facility will produce a minimum of 100,000 tonnes per annum of high quality Refused Derived Fuel (RDF) as a feedstock for the Levenseat Power Plant, while also maximizing both the recovery of high value recyclates (such as paper, cardboard, plastics, metals and wood) and the waste diversion from landfill. The system will also produce a Solid Recovered Fuel (SRF) stream from the super-light and high calorific non-recyclable waste commodities.

To meet the objectives of the plant, Machinex is employing the latest technologies including four shredders, one Machinex trommel, one waste screen, three air separators, two MACH Ballistic separators, three MACH Hyspec optical sorting units, one belt dryer and two Machinex single ram balers. One of the balers will be used for recycling commodities, while the second baler will be dedicated to handle RDF & SRF bales. This baler was developed by Machinex specifically for the waste to energy industry to handle RDF baling. This machine incorporates plastic strapping and bale wrapping as part of the RDF solution.

To increase and assure the quality of RDF recovered from the stream of fines, which includes wet organic waste, belt drying technology was also selected. The continuous dryer is self-sustainable and will use heat generated by the waste to energy plant adjacent to the MRF.

According to Machinex, the installation is progressing as scheduled and the customer is pleased to see the project come to life. “We have been very impressed with Machinex as a company, they were more than willing to work with us to find an appropriate, robust and creative solutions for our project," said Angus Hamilton, Director at Levenseat Ltd. "They have been very professional and have shown a dedication to not only completing the project on time but also making sure we were satisfied throughout. Above all we felt Machinex really listened to and understood our requirements and worked with us to produce a design that aligned perfectly with what we were aiming to achieve.”

King County building on significant increase in tonnage

The recently upgraded Bow Lake Recycling and Transfer Station manages more than one third of all solid waste handled in Washington State’s King County

The King County Solid Waste Division, located in the Puget Sound region in western Washington State, saw a 41 percent increase in recycling tonnage at its network of transfer/recycling facilities and rural drop box stations in 2016, compared to 2015. According to King County, the increase is the result of an expansion of services and types of recyclable materials accepted, infrastructure upgrades, revamped signage and additional employees available to answer customer questions about recycling at all of its facilities. All of this has meant a jump in the number of customers who brought their sorted recyclable and compostable materials to King County facilities.

Maximizing Revenue at the City of Hamilton

Machinex' Mach Hyspec optical sorter at the City of Hamilton MRF.

After completing an efficiency and effectiveness (mass balance) audit on its container line in 2014, the City of Hamilton set to work on implementing a series of upgrades to improve its capture rates and revenue earning potential. The initial audit, commissioned by Ontario's Continuous Improvement Fund (CIF) and performed by a private consulting firm, estimated that the City of Hamilton could obtain approximately $700,000 in additional revenues annually if all of the material entering the container line were correctly sorted to appropriate grades.

The Cortex (aka Clarke) is a robotic unit developed by AMP, using optical scanning and specialized grippers that allow it to differentiate and pick up material from moving belts

Sorting of food and beverage cartons is a challenge for most MRFs in the recycling industry. It's a tough job that is today mostly done by human pickers who need to move fast and quickly recognize the products going past on the line before separating them from the overall waste stream.

Former excavator operator right at home with purpose-built SENNEBOGEN material handler

Chris Zwicky has spent much of his life operating excavators. But, only a few months after climbing into the spacious cab of a purpose-built material handler, he's already sold on the advantages that the SENNEBOGEN 818 M offers his family's busy earthmoving, processing and biomass production business in eastern Pennsylvania. Zwicky Processing & Recycling, part of W.D.

Connecting Supply with Demand

On a global basis only about 14 percent of plastic packaging is collected for recycling, and across the healthcare sector these rates are significantly lower. As noted in the World Economic Forum's 2016 white paper, The New Plastics Economy: Rethinking the Future of Plastics: "Today's plastics economy is highly fragmented. The lack of standards and coordination across the value chain has allowed a proliferation of materials, formats, labelling, collection schemes, and sorting and reprocessing systems, which collectively hamper the development of effective markets. The development and introduction of new packaging materials and formats across global supply and distribution chains is happening far faster and is largely disconnected from the development and deployment of corresponding after-use systems and infrastructure."
