Interstate Waste Services ramps up New Jersey MRF

Teaneck, New Jersey-based Interstate Waste Services Inc. (IWS) has begun operating a new material recovery facility (MRF) in North Arlington, New Jersey, about 12 miles from New York City.

“We are super excited to announce that our new state-of-the-art recycling facility in North Arlington is officially open,” IWS writes in a late February post on the firm’s LinkedIn page.

The company adds, “This facility is more than just a technological marvel, it also represents our ongoing investment in the communities we serve.”

In February 2024, IWS and its Action Environmental Services business unit announced Action had been selected as an authorized waste and recycling hauler in 14 out of 20 New York City commercial waste zones as part of the city’s commercial waste hauling program.

“We look forward to building on our 25-year legacy of investing in innovative recycling technology, expanding operations and serving the people of New York City with efficiency and sustainability at the forefront of what we do,” IWS CEO Michael DiBella commented at that time.

Subsequent to the announcement, IWS has made two acquisitions it says will help support servicing the commercial zone contracts. Last year it acquired Connecticut-based Oak Ridge Waste & Recycling and Marangi Disposal of Middletown, New York.

In a 40-second video clip embedded in its LinkedIn post, equipment made by Canada-based Machinex Technologies is highly visible, including the technology provider’s SamurAI sorting robot and a Mach HySpec optical sorting unit.

Likely because of the MRF’s intake of discarded commercial materials, interior shots of equipment at work in North Arlington show a sizable percentage of old corrugated containers (OCC) and other packaging boards in the stream, including OCC bales being produced.

The same video clip denotes the new commercial MRF’s capacity as 350,400 tons per year.

LoCI Controls system demonstrates early methane capture success

Wareham, Massachusetts-based LoCI Controls, a developer of software technology for real-time monitoring and control for optimizing landfill methane capture, has announced results from its methane capture project at Loess Hills Regional Sanitary Landfill, owned and operated by Iowa Waste Services LLC, a subsidiary of Waste Connections Inc., The Woodlands, Texas.

Between 2021 and 2023, the project successfully captured and destroyed methane emissions with approximately 229,000 metric tons of carbon dioxide equivalent (CO2e), equal to removing more than 53,300 gasoline-powered cars from the road for one year, LoCI Controls says.

LoCI says these results demonstrate Loess Hills Regional Sanitary Landfill’s commitment to reducing greenhouse gas emissions and driving positive environmental change. 

Additionally, the sale of carbon credits from the CO2e captured, quantified via Ambitious Climate Results methodology, also offers a new revenue source and financial incentive to capture more methane than currently required by regulation.

“LoCI’s real-time data and actionable insights empower landfill operators to make informed decisions, whether it’s resolving daily operational challenges or planning long-term infrastructure investments,” says Peter Quigley, CEO and chairman of LoCI Controls. “Our partnership with Loess Hills Regional Sanitary Landfill and Waste Connections demonstrates how innovation can drive greater efficiencies and success for landfills and downstream beneficial use of the captured methane. We’re proud to support their efforts and remain committed to enhancing gas capture and operational excellence in the years ahead.”

Located in Malvern, Iowa, the Loess Hills Regional Sanitary Landfill implemented a voluntary methane collection and destruction system in 2021. In 2023, it added enhancements from LoCI Controls’ advanced gas automation and control technology, the company says.

With the deployment of the LoCI Controls system, in combination with the installation of landfill gas collection system infrastructure as an integral part of new cell construction projects, gas generated from new waste was collected earlier, more efficiently and more reliably, enabling methane capture in higher quantities and at more consistent quality, according to the news release.

The LoCI system provides frequent well monitoring and control in both inactive and active areas of the landfill, the company says, limiting air intrusion and maximizing methane gas capture. The system also enables operators at the site to capture and stabilize gas composition autonomously, resulting in greater efficiency and personnel safety.

Minnesota city commissions composting system

Creekside Soils, a municipal composting facility run by the city of Hutchinson, Minnesota, has commissioned a covered aerated static pile (CASP) composting facility designed by Green Mountain Technologies (GMT) to increase its food waste diversion program’s capacity and processing efficiency.

Hutchinson has operated a citywide curbside source-separated organics materials (SSOM) diversion program since 2001, making it one of the oldest SSOM diversion programs in Minnesota. Creekside also composts yard waste in turned windrows and produces landscape mulches. Its bagged soil and mulch products are sold over a 24-state area.

Since 2001, more than 4,000 single-family households in Hutchinson have been able to dispose of food waste and yard waste through year-round weekly curbside collections.

Compostables are delivered to Creekside for processing in the recently constructed six-zone, below-grade CASP composting system designed and commissioned by GMT, based in Bainbridge Island, Washington.

The CASP system at Creekside has an annual capacity of up to 1,500 tons, and each zone has an individual blower that is automatically controlled by GMT’s WebMACs control system, using a data probe inserted into each pile.

“When exploring options for a new system, cost and operational efficiency were the two main focal points,” says Andy Kosek, general manager of Creekside Soils, of the new system. “The GMT CASP system checked all the boxes.”

The CASP system allows Creekside Soils to produce high-quality compost with minimal operational demands by using temperature control feedback to keep pile temperatures at the setpoint needed to maintain optimal composting conditions at all times, GMT says.

Additionally, the below-grade aeration floor installed requires minimal operational interference between batches.The facility was designed and positioned to allow the system to be expanded to 3,000 tons per year at a later date.

Mavitec Green Energy expands in US market

Mavitec Green Energy, a Netherlands-based provider of food waste and depackaging solutions, says it is growing its U.S. presence after appointing Rutger Zweers as vice president of sales. The expansion includes introducing its Paddle Depacker 2.0 to the U.S. market and establishing warehouses to better support its North American customers.

With more than 25 years of experience in the waste industry, Zweers brings global expertise and a deep understanding of custom-engineered systems, according to Mavitec. Having worked in the North American market for two decades, he is well-positioned to drive Mavitec’s mission forward, the company says.

Mavitec is shipping three depackaging systems to projects across the eastern, Midwestern and western U.S. In addition, the company is setting up two central spare parts locations, one on the East Coast and one on the West Coast, to ensure fast and efficient support for existing and future clients. The first facility, in Salt Lake City, is expected to be stocked and operational by the end of April, according to the company.

Mavitec adds that its solutions will play a key role in a flagship renewable natural gas (RNG) facility in Indiana.

Widely used by European companies such as Veolia, Suez and PreZero, Mavitec says the Paddle Depacker is designed to efficiently separate organic material from packaging, producing clean organic output with roughly 99.7 percent purity, making it ideal for biogas production.

Mavitec says the system has numerous advantages, including heavy-duty construction, with a robust, reliable design for continuous operation; high processing capacity that delivers superior separation efficiency; user-friendly access thanks to hydraulic doors that offer quick cleaning and maintenance; and low noise because it is designed with insulation.

Mavitec Green Energy also offers additional solutions for further processing organics, including grit removal and plastic cleaning, according to the company.

The company’s Paddle Washer is designed to further purify output by washing and separating any remaining contaminants from the organics, enhancing overall quality. To further optimize purity, the Grit Cyclone removes sand, stones and other heavy particles from the organic slurry. By using centrifugal force, this system ensures a smoother digestion process and prevents wear and damage to downstream equipment, making it an essential addition for high-quality biogas production, Mavitec says.

“Expanding into the U.S. market is a major milestone for Mavitec Green Energy,” says Maco van Heumen, CEO of Mavitec. “By combining our industry expertise with a strong local presence, we are committed to delivering the highest-quality food waste processing solutions while supporting the growing demand for sustainable waste management.”

Russelectric spotlights paralleling systems for water, wastewater treatment facilities

Siemens business Russelectric, a Hingham, Massachusetts-based manufacturer of automatic transfer switches and power control systems, is spotlighting its Paralleling Systems to protect water and wastewater treatment facilities and the functions they perform.

The company says the systems are ideal for ensuring optimal power support for critical loads when transferring between live power sources in water and wastewater treatment facilities, whether for use in utility paralleling, prime power or open/closed transition emergency systems.

The Utility Paralleling system also can be configured for peak shaving, utility-sponsored load curtailment programs, exporting power to the grid and for a variety of combined heat and power applications, Russelectric says.

Russelectric paralleling systems incorporate dual, redundant, live synchronized programmable logic controllers (PLCs) for system control. Discrete hardwired components such as switches, meters and control devices are standard to allow for manual control capability in the unlikely event that both system PLCs fail, the company says. In addition, with a Russelectric Utility Paralleling System, users get soft loading transfer and phase lock synchronizing capabilities when paralleling with the utility, which reduces transients and controls the loading to the engine generators, according to the company.

All Russelectric paralleling systems are UL listed, the company says. Selector switches are provided for open/closed transition, automatic/manual paralleling of generators and utility sources and automatic/manual retransfer between both sources of power, where applicable.

The Utility Paralleling System offers a choice of either momentary paralleling with the utility or sustained paralleling for soft loading, Russelectric says.

Also available is paralleling of generator sets with the utility upon return of the utility source after power interruption.
