In September the City of Bangor will formally move over to a new arrangement in which residents will throw all of their recycling in with their trash and leave the mixed waste to be picked up from the curbside every week, as now happens with trash.
Bangor will also close their local recycling station as part of the city’s switch to a new integrated waste conversion plant in Hampden developed by Coastal Resources of Maine with Fiberight technology. The new facility includes a materials recovery facility (MRF), organic processing, plastics processing, anaerobic digestion (AD) and wastewater treatment. The integrated technology is intended to increase recycling rates without the need for extensive outreach programs and is easier for customers to use. According to Coastal Resources of Maine, the benefits are:
The advanced technologies are undergoing final testing at the Hampden, Maine facility, and are already in use at automated material recovery facilities in the United States and in Europe. The end product is cleaner and provides more diverse types of materials that can then be reused to create new products.
The Hampden facility’s advanced MRF has a high degree of separation, recovery, and monetization of commodity products, and then employs additional processes for generating clean cellulose, engineered fuels, and biogas from traditionally non-recyclable materials. Hired for the firm’s technical expertise and experience planning large municipal solid waste and biogas programs and facilities, SCS provided an in-depth examination and analysis of the technologies, program sustainability, and potential economic impacts of the facility.
The facility will serve 116 municipalities and public entities represented by the Municipal Review Committee, a non-profit organization that currently manages the waste disposal activities in Eastern and Northern Maine. The facility is planning to start accepting waste from its municipal customers shortly.
“With the planning and cooperation of many, Fiberight’s providing a truly sustainable solution in Maine while solving several challenges when consumers separate their recyclable materials and eliminating contamination,” stated Bob Gardner, SCS Engineers Senior VP. “The facility is capable of reusing nearly 150,000 tons of what formerly went into a landfill, is processing more municipal solid waste into high-value commodities, and is helping local municipalities and private waste haulers offset the cost of recycling.”
Material recovery facilities (MRFs) are seeing many challenges that directly impact operations. Some of these challenges include: new recycled material quality standards from China, the ratcheting up of voluntary and mandatory local and state recycling goals, lower tolerance for worker injury, increasing volumes and a changing waste stream, disposal bans on organics in landfills, and high demand from emerging energy
markets for organics.
MRFs equipped with the latest technologies are able to meet tightening standards for traditional quality recycled materials and some are also starting to provide a separate, clean organics stream for downstream alternative energy projects. Many MRF operators are now benefitting from these new technologies, with increased throughput and quality of end product.
The article by Bruce Clark and Mike Kalish of SCS, provides an overview of the latest developments in MRF processing equipment systems that are helping owners and operators meet these challenges and at the same time helping maintain a healthy bottom line.
