Latest Green Machine Mixed-Materials MRF online on Long Island
Green Machine, the New Hampshire-based manufacturer of recycling and solid waste processing equipment and systems, recently completed a mixed-materials MRF upgrade for Winters Bros. Waste Systems based out of West Babylon, (Long Island) New York at one of the company’s transfer and recycling centers. The processing equipment at the facility was originally built by Green Machine in 2003, for Winters Bros. The new upgrades include a new Green Eye hyper spectral optical sorting system, MSW sizing screen and magnetic separation technology.
“Our latest mixed materials MRF upgrade for Winters Bros., is designed to handle both mixed residential post-recycled MSW and mixed dry commercial waste,” explains John Green, president of Green Machine. “The commercial dry waste they are handling includes industrial loads that consist of 50-percent corrugated content, with the balance being trash and other recyclables.
“With the post-recycled MSW they receive, the material has already been collected and processed through a dual- or single-stream program. Winters Bros. is able to valuable materials from the waste stream prior to shipping materials off the Island for disposal.”
“For mixed MSW, Winter Bros. is now able to processing between 35 and 50 tons per hour,” says Green. “With dry commercial waste, it is more along the lines of 20 tons per hour.”
Winter Bros. operates 13 transfer stations, 8 recycling centers and multiple collection operations, across Long Island, New York and in Connecticut.
“On Long Island, there are no landfills for MSW,” said Bill Brennan, Vice President of Transfer and Recycling Operations for Winters Bros. Waste System. “Almost all of the commercial waste that is generated on Long Island is shipped off the island to landfills in upstate New York, Pennsylvania and Ohio.”We have always been committed to enhanced recovery of recyclables from the waste stream for the betterment of the environment and to decrease the amount of MSW volume that needs to be transported off the island to costly landfills.
“The newly installed, Green Machine allow us to be efficient in the handling of both bulky dry waste and MSW.
Green Machine’s patented Green Eye optical sorter is also a key technology on this upgrade. The Green Eye uses artificially intelligent hyper spectral technology to automatically identify and sort a wide range of materials, offering very clean output and efficient recovery of valuables, reducing labor costs while increasing throughput.
“Our Green Eye gathers information based on an object’s molecular structure,” says Green. “This technology is like no other sorter, and is solving a multitude of industry material processing challenges with efficiencies exceeding 94 percent, at ever-increasing sort speeds.”
With the new MSW separation screen, additional magnetic separation and the addition of the Green Eye optical sorter, the amount of recyclables that Winters Bros. will recover from their residential MSW stream has increased dramatically, sending less waste to landfills.
“Green Machine’s theory of mixed waste separation is one in which, ideally, there is limited capital expenditure on the equipment, high throughput, lower maintenance and decreased labour required,” says Green.
“In mixed materials MRF applications, operators should be looking to collect the ‘low-hanging’, high-value recyclables, with limited labour. With a system like Winters Bros.’, running 50 tons an hour, the number of sorters required would be about 10. With additional optical sorting, we could remove even more sorters and increase throughput.”
“We are the biggest and best recyclers on Long Island,” said Billy Brennan of Winters Bros. “We are always looking to enhance the effectiveness of our facilities. The new technology from Green Machine makes it possible to recover even greater amounts of recyclables from the waste steam resulting in higher recycling rates and less trash to ship to distant landfills. With these system upgrades by Green Machine, we are confident that we will remain the #1 recycler on Long Island as we work to preserve and protect our environment in a cost effective and environmentally sound manner.”
