Cyprus: Vassiliko Cement’s Vassiliko cement plant was the site of a tyre fire in an alternative fuel (AF) storage area on 11 June 2022. The Cyprus Mail newspaper has reported that the fire begun due to a mobile shredder malfunction. Enerco Energy Recovery operates the shredder at the 2.5Mt/yr cement plant. Local residents protested the incident at the site of the plant’s former quarry on 13 June 2022.

Germany: BHS-Sonthofen has launched the RAPAX pre-shredder. The supplier says that the shredder is able to handle various waste fractions including commercial, industrial and construction waste and metal fractions. It is available with shaft lengths of 1.2 – 3.2m. Shafts are able to move synchronously, asynchronously or in reverse.

Mechanical designer Ingo Schneeman said, “The input materials used by our customers can vary greatly, especially in the area of metal recycling. Whether it’s small electrical equipment or white goods, for example, our various programs ensure optimal shredding.”

Costa Rica: Geocycle Costa Rica has commissioned a XR3000C type shredder supplied by Austria-based Untha. The unit will be used to process locally sorted municipal solid waste (MSW) and hazardous and non-hazardous Industrial Solid Waste (ISW) into refuse-derived fuel (RDF) for use at Holcim Costa Rica’s integrated cement plant.

“Having worked with Untha in other countries, the XR3000C was chosen for its flexibility, high-capacity and single step alternative fuel capabilities. We also knew it would be supported by a world-class engineering team,” said Geocycle’s general manager Wilkie Mora Bolanos.

Geocycle is the waste processing subsidiary of Switzerland-based LafargeHolcim. There are currently over 20 Untha shredders in operation in Geocycle facilities worldwide.

Denmark: Norway-based Geminor has established a solid recovered fuel (SRF) production line with a capacity over 40,000t/yr at its Hub waste processing plant in Aalborg. The line will shred and mix municipal solid waste from the region. Geminor will supply 120,000t of SRF to Aalborg Portland Cement over a three year period starting from January 2021. The line includes a chain feeding conveyor supplied by Westeria, a Metso 4000-8 pre-shredder, a Steinert magnetic sorter and a Metso 3550 fine shredder. Aalborg Portland Cement is targeting a 75% SRF substitution rate at its Aalborg cement plant over the period.

South Korea: Finland-based BMH Technology has secured a contract to supply three waste shredding lines at Ssangyong C&E’s integrated cement plants at Donghae and Yeongwol. The lines will supply solid recovered fuel (SRF) for the units. Each line will include a Tyrannosaurus type FineScreen and Air Classifier for separating impurities. The full delivery will contain five Tyrannosaurus type FineShredders. The lines will be commissioned in the autumn of 2021.

Donghae plant will become one of the world’s largest SRF shredding plants producing alternative fuels for the cement industry once the order is complete. The unit will produce 80t/hr of SRF with a particle size under 25mm using two lines and four shredders. The cement plant is the world’s largest with a production capacity of 11.5Mt/yr.

Argentina: LafargeHolcim waste management subsidiary Geocycle has begun shredding waste at its Córdoba co-processing plant using a new Untha XR3000C one-step shredder supplied by Austria-based Untha. The shredder will produce refuse-derived fuel (RDF) for use at LafargeHolcim’s Córdoba cement plant. It is the 10th Untha shredder Geocycle has commissioned.

Director Mariano Bollo said, “Geocycle Argentina is no stranger to waste shredding for alternative fuel (AF) production. We previously used a dual-shaft machine manufactured by a competitor of Untha’s, but the capacity and reliability of our machine continued to cause us problems. Untha’s low speed, high torque drive means this is a powerful machine with impressive uptime, ease of maintenance and proven capabilities. This – combined with the shredder’s versatility – meant the business case to switch to an XR was strong. While we think carefully about every decision we make, to ensure each shredder we invest in has absolutely the right configuration for every single plant, we now run a number of Untha machines across our global group,” continued Mariano. “The whole life operating costs of this shredder are extremely low, which means we can consistently produce a profitable, environmentally-sound fuel. It therefore comes as little surprise that we’re looking to standardise the technology we use across our business. This has benefits when it comes to procuring and sharing spare and wear parts too. Working in collaboration with Untha’s local engineering specialists, Geocycle is now optimising the design and layout of the waste processing line to double throughputs in early 2021. This XR investment aligns with our global AF production strategy, which doesn’t just improve our cement manufacturing footprint worldwide – it transforms the environmental status of our local communities too.”

Germany: Vecoplan has launched the VRZ 2500 shredder and the VPC 1600 pre-shredder, which can be combined with the VHZ single-shaft shredder.

The new addition to the VRZ series is intended for recycling and reprocessing waste wood. The unit is equipped with sickle-shaped ripper teeth and is intended for minimal maintenance through the use of HiTorc direct drives. The drives have a capacity of 2 x 138kw and are resistant to tramp materials. They are also dynamic, offering improved start-up and reversing behaviour. “During the development of the new VRZ series shredder, we placed great emphasis on making it robust, resistant to intrusive materials, reliable and low-maintenance,” said Martin Baldus, Head of Industrial Shredding development at Vecoplan.

The VPC 1600 is a pre-shredder intended for use with voluminous objects and bulky wooden items such as pallets. Notably, the new version of this product can be combined with the VHZ single-shaft shredders (VHZ 1600 and VPC 1600) to increase throughput by up to 50% and to save space. With its working width of 1600mm, the 800mm-high VPC is designed to fit exactly onto the VHZ with a sliding frame connecting the shredder and the pre-shredder. The VPC is permanently fixed during operation but it is designed to be moved at other times if an operator has to change the counter-knives in the shredder. The filler port of the new pre-shredder measures 1605 x 1605mm and the drive power is 2 x 9.2kw. Sixteen counter-crushers have been integrated into the machine and it also has two independently running rotors, each with a speed of ten revolutions per minute.

Austria: Andritz has announced its upcoming line of ADuro primary and secondary shredders. The shredders, which it says are ‘for shredding refuse-derived fuels and municipal solid waste, as well as commercial or industrial waste,’ become available in July 2020. Andritz said, “The Andritz automation tools can be tailored to individual customer needs and provide powerful capabilities to monitor machine behaviour and improve plant reliability.”

Spain: Switzerland-based LafargeHolcim subsidiary Geocycle has commissioned an UNTHA XR3000C shredder at its Albox waste processing plant in Almeria. The 15,000t/yr shredder will process domestically-produced commercial and industrial waste, including oil- and solvent-contaminated textiles, plastics, paper and cardboard, into fuel suitable for co-processing at any of LafargeHolcim’s five Spanish cement plants. Geocycle Operations Manager Raúl Lannegrand said, “Co-processing is recognised by the United Nations Environmental Programme (UNEP) Basel Convention and the European Commission as a practical, cost-efficient, safe and environmentally-preferred waste treatment method, so it was important for us to make the most of the landfill diversion opportunity we had identified in Spain.”

Germany: Red Dot has awarded Vecoplan its Red Dot Design Award for the new Vecoplan VEZ 3200 pre-shredder for refuse-derived fuel (RDF). The prize ‘acknowledges the aesthetics and workmanship’ of the product, as well as its ergonomiocs and functionality. Vecoplan CEO Werner Berens said, “The design impacts on the machine construction, making the shredder easier to handle for operators.”
