GJF launches anti-contamination container
Skip manufacturer GJF Fabrications has launched a container to reduce contamination of recyclable materials at Household Waste Recycling Centres.
The Qualitainer Hooklift has been designed by GJF in light of an increased focus from local authorities and contractors on improving the quality of recyclable materials from municipal collections.
GJF’s managing director, David Gillett, said: “The Qualitainer Hooklift has been developed after listening to municipal recycling site managers and site staff across the UK.
“They widely report persistent problems of contamination dumped in Hooklift containers for recyclable materials, even on sites where budgets still allow them to be well populated with staff.”
The Qualitainer Hooklift has wide aperture mesh sides that allow the contents of the Hooklift container to be seen along its full length and full height from both sides, so that any contamination dumped in with recyclate can be identified and removed before it spoils the entire load.
Local authority officers at the Local Authority Recycling Advisory Committee (LARAC) Conference and Exhibition were among the first to see the Qualitainer first hand this month, with GJF having offered an advanced preview of the container at the event (see letsrecycle.com story).
Initial shipments of the product are expected from 12 December.
Goudsmit re-designs non-ferrous separator
The complete line of Eddy-Current non-ferrous separators from Goudsmit Magnetic Systems BV has been redesigned for reduced cost and technical improvements.
The aim of the redesign was to improve ease of use, durability and return on investment, the company says. Special focus was placed on the frame, accessibility for service and magnetic rotors.
According to Goudsmit, the technology offers same grade/recovery performance and high level of quality at a “considerably lower” purchase price.
Applications of Eddy-Current separators include: household waste (shredded), incinerator slags from household waste, WEEE scrap, glass recycling, heavy and light shredder residues (e.g. Auto Shredder Residue), wood and/or chipboard recycling.
Ribbex installs grit removal system
Commercial waste firm Ribbex UK Ltd has expanded its waste handling capabilities with the installation of a CD Enviro S Grit removal system, the G:MAX.
Ribbex’s investment in the G:MAX, allows for a much more diverse range of waste streams to be handled, the company says. As a result Ribbex can take on a much higher volume of materials allowing them to double their current capacity by 2017.
The modified version of the G:MAX screening and grit recovery equipment will see a larger screen installed to allow Ribbex to handle increased dry solid loading. The G:MAX’s dual stage washing and recycling capability also enables it to efficiently remove particles that would otherwise wear and damage downstream processes.
The waste services originally carried out by The Honeywagon Company Ltd was recently incorporated into the more diverse waste management solutions of Ribbex, after formal acquisition in September 2015.
The G:MAX was installed at Ribbex’ Welwyn Garden City treatment plant, which handles in excess of 1,000 tonnes of waste each month.
Shredding technology boosts Ecogen capacity
Confidential document destruction and shredding capacity at Hampshire-based Ecogen Recycling has jumped sevenfold following a £90,000 investment in new technology.
The investment allowed the installation of a custom-made conveyor system, developed by waste recycling machinery specialist Middleton Engineering, feeding an AXO-704 shredder with prototype ‘hard head’ technology.
The Middleton solution, which is designed to optimise material feed to and from the shredder, is capable of handling seven tonnes per hour and is designed to minimise floor space.
Ecogen Recycling handles commercial waste recyclables from commercial clients in retail, manufacturing and distribution across the UK with a national collection service.
With the new facility in full operation, Ecogen Recycling is currently processing around 100 tonnes a week of secure document shredding.
Ecogen commercial director James Lewis explains: “This £90,000 investment has future proofed this part of our business taking shredding capacity from one tonne to seven tonnes per hour. That’s equivalent to 28 fully laden artic trailers a week.”
ETW Energietechnik upgrades biogas to RNG
German company ETW Energietechnik GmbH has optimized Pressure Swing Absorption (PSA) technology – a process for gas upgrading in large scale industrial applications – for the biogas upgrading process.
The technology, which upgrades methane from biogas to renewable natural gas (RNG), was developed by a team of adsorption specialists, plant builders and mechanical engineers.
ETW’s biomethane plant can automatically adjust pressure swing cycles to a varying inlet gas quality and volume flow. This enables total operator control over the outlet gas purity (over 99%) or the desired heating value, the company says.
According to ETW, operators of waste or sewage plants who deal with changing biogas quality and flow, or those who want to shift between the electricity and/or RNG markets to maximize income, in particular can benefit from the process control system.
