US: Geocycle North America has received a new Untha XR mobil-e waste shredder at its plant in Dorchester, South Carolina. The mobile unit with 2 x 177hp motors, will process non-hazardous post-industrial waste to produce refuse-derived fuel (RDF) for LafargeHolcim’s Holly Hill cement plant. The shredder is currently configured to manufacture 10t/hr of RDF and the plant aims to generate 35,000 – 40,000t/yr of the fuel. Untha says that the new product replaces a previous shredder from another manufacturer.

US: The Rhode Island Fiberglass Vessel Recycling pilot project (RIFVR) has completed its first major delivery of boat-hull materials to a cement producer in South Carolina. The project is a collaboration between the Rhode Island Sea Grant and the Rhode Island Marine Trades Association (RIMTA) to dispose of fibreglass recreational boats in a sustainable manner, according to the Providence Business News newspaper. The program will now look into how it could expand its network model.

US: RePower South has starting processing materials at its new 0.2Mt/yr waste processing plant at Moncks Corner in South Carolina. The unit uses equipment supplied by Bulk Handling Systems (BHS) as part of its BHS FIberPure process that utilises screen, air, optical and artificial intelligence (AI)-powered robotic sorters. It also uses seven NRT optical sorters and nine Max-AI Autonomous Quality Controls (AQC). The plant can process up to 50t/hr of mixed waste to produce a fuel feedstock.

The plant also produces ReEngineered Feedstock (REEF) from non-recyclable papers and plastics. This fuel product is sold to industry, cement, and utility customers to replace coal in production processes. The fuel system uses a Loesche Energy Systems RocketMill to dry, purify and size the REEF.

Belarus/Hungary/US: Italy’s Entsorga is working on alternative fuel projects for cement plants in the US, Belarus and Hungary. In the US it has signed a contract to supply a Pelican feed line at Argos Cement’s Martinsburg plant in West Virginia. It follows a long-term off take agreement in place with the cement producer to supply alternative fuels. The 60,000t/yr feed station is similar to a feed station already delivered in 2016 in Nazareth, Pennsylvania.

In Belarus the waste engineering company plans to install an alternative fuel feed line at the Krasno cement plant. Local subsidiary EntsorgaFin will define the material acceptance standards and provide the design for the fuel feed station and feed line.

In Hungary Entsorga was awarded a contract for the supply of an alternative fuels automated handling and feeding system in January 2019 with an unnamed global cement producer. It will provide its Spider and Pelican products to the end user. Commissioning of the plant is scheduled for early 2020.

US: BioHiTech Global started operations at a waste treatment plant in Martinsburg, West Virginia in March 2019. It has completed the first phase of plant commissioning including the facility's reception area, overhead bridge cranes, and its primary mechanical sorting equipment. It has begun the next phase of plant commissioning and progressing operations, which includes receiving limited amounts of waste and beginning runs of its mechanical and biological treatment process for producing solid recovered fuel (SRF). The limited processing runs are expected to result in the production of SRF in the coming weeks with the facility reaching full operations in the second quarter of 2019. The unit uses Entsorga Italia’s proprietary high efficiency mechanical and biological treatment process (HEBIOT)

The majority of the waste, to be delivered as feedstock to the facility, is covered under a ten year agreement with a local waste hauler owned by Gold Medal Group, a regional waste management services company. The SRF will be supplied to cement producer Argos USA under a similar ten-year deal.

"The initiation of revenue generating operations at this first facility of its kind in the US is a pivotal moment for our company and an important step forward in the movement to lessen the environmental impact of waste management,” said Frank E Celli, the chief executive officer (CEO) of BioHiTech Global.

BioHiTech is the largest owner of the Martinsburg SRF plant through a majority owned subsidiary company with a 78% controlling interest in its operations. Gold Medal Group owns the remaining minority stake in the subsidiary.

US: LafargeHolcim’s Ravena cement plant in New York is considering burning tyres as an alternative fuel. Environmental Director Kevin G Bretz told Coeymans town officials that the cement producer has ‘developed relationships’ and held ‘preliminary discussions’ with potential tyre suppliers, according to the Times Union newspaper. The cement producer was hoping to use an approval by the state Department of Environmental Conservation granted in 2006 that gave permission for it to burn up to 4.8 million tyres annually at the plant. However, this Beneficial Use Determination (BUD) expired in mid-2018.

US: Lehigh Cement’s is preparing to co-process ‘raggertail’ at its Glens Falls plant in New York state. The state Department of Environmental Conservation (DEC) has prepared a draft air pollution permit for the unit. It is accepting public comments until late December 2018.

Raggertail is derived from non-recyclable ‘raggertail’ residuals processed by Frontier Fiber from Norampac and Greenpac recycled paper mills in Niagara Falls. It consists of approximately 60% plastic and 40% fibre (biomass). Emissions testing performed at the plant while burning the alternative fuel on a trial basis demonstrated that its use will not cause ambient impacts above State guideline concentrations. At present the cement plant’s kiln is powered by natural gas and coal.

US: The city of Fort Myers in Florida is planning to send 30,000t of ‘toxic’ sludge for disposal at LafargeHolcim’s Theodore cement plant in Alabama. The waste will be transported by truck to LafargeHolcim quarry north of Crystal River for pre-treatment and then onto the Theodore plant, according to the Citrus Country Chronicle newspaper. The company hopes to start the removal process in October 2018 and complete it by the end of the year. Permit application for the removal process are still on-going. The ‘toxic’ sludge came from the city’s water plant. It was dumped in fields in Fort Myers from the 1960s to the 1990s.

US: RePower South (RPS) has reached an agreement with Montgomery, Alabama to operate the city’s materials recovery facility (MRF). RPS will invest US$12m in the City of Montgomery Recycling and Recovery Facility. RePower South has partnered with Bulk Handling Systems (BHS) and Loesche Energy Systems to upgrade the existing recycling system to also produce refuse-derived fuel (RDF) to be sold to cement, power stations and other industrial customers.

The system will process 45t/hr of mixed waste to capture cardboard, metals, paper, plastics and produce fuel. New equipment joining the existing BHS screen, Nihot air and NRT optical sorting technologies include a primary reducer, two NRT optical sorters for fuel cleanup, a Loesche fuel system reducer and PAAL Dokon baler. In total, the system features 10 optical sorters, ensuring the positive recovery of fibre and containers and removal of contamination from fuel.

Repower South holds an exclusive regional license from Accordant Energy for the development, manufacture and sale of ReEngineered Feedstock fuel.

US: Cadence Environmental Energy has promoted Ted T Reese to Executive Vice President. Cadence provides technology for waste fuel recycling and emission reduction technology to the cement industry and is the exclusive supplier of waste-derived fuels for Ash Grove Cement. As part of the company’s succession plan founder Ted J Reese plans to hand over the presidency to Ted T Reese in 2019.
