Robert Craggs (pictured below at right), solid waste and resource recovery manager at Burns and McDonnell, says, “The engineers at Green Machine devised a unique system design that incorporated all of the existing dual-stream equipment within their single-stream system upgrade. Their design efficiencies greatly enhanced their system cost and met the counties available budget.”
Donnie Hopp (pictured below at left), McLeod County material recovery facility (MRF) manager, says he is pleased with the single-stream system’s performance.
He says the volume of material the MRF is processing has increased by 20 percent since the county converted to single-stream recycling in the spring of 2015, adding that residents have responded well to the change and are keeping contamination at a minimum.
Hopp notified buyers of the MRF’s sorted recyclables that the county was switching to a single-stream system because he “didn’t want them to be surprised,” he says. “They haven’t even noticed that
The MRF continued operating throughout the installation of the new single-stream system from Green Machine because the county didn’t want to lose revenue and had no place to stockpile collected recyclables, Hopp says. “The installation was not easy and straightforward,” he adds.
Despite the challenges associated with this situation, Hopp says, “We were operating at promised production rates within one week of commissioning on schedule. The Green Machine system started up with very few hiccups.”
He adds, “We are now accepting both municipal and private hauler collected single-stream and industrial and commercial waste.”
John Green, president of Green Machine, says, “I feel that one of our strengths is our willingness to integrate existing site conditions and equipment into a simplistic system design. Cost savings realized through use of existing equipment enabled the deployment of new a metering bin feeder system, Z-Pan infeed system, presort, two-deck OCC screen with postsort, glass breaker, eddy current and single-sided container sort with automation of existing bunker systems.”
Hopp was impressed that Green, as the president of the company, took the time to visit the facility. “He was great to work with,” he says.
Regarding Green Machine and Burns and McDonnell, Hopp says, “I would definitely work with them again.”
