UK: Austrian shredder producer Lindner has released details about the installation of a Polaris 1800 shredder on the island of Guernsey in the English Channel. The machine was installed in early 2019 on behalf of Island Waste, part of the Guernsey Recycling Group, to produce solid recovered fuels (SRF). Upon delivery challenges had to be overcome including limited availability of hoisting equipment. At present he shredder processes around 8t/hr of municipal waste into SRF.

Australia: Focus Enviro, a waste and organic equipment specialist, has secured an exclusive agreement with Austria’s Untha, making it the distribution partner for Untha’s shredding technology in Australia. Focus has its headquartered in New South Wales and it has a presence in Victoria, Queensland and the west of the country.

Untha’s director for global business development, Gary Moore, described Australia as one of the most exciting energy from waste markets in the world despite alternative fuel production being less developed than in Europe. “Landfill rates are rising, environmental pressures are mounting, China’s landmark movement has forced a new direction for the country’s waste framework, and a number of international waste operators, with a presence in Australia, are driving a global knowledge transfer programme to strengthen resource security,” said Moore.

South Korea: Austria's A Tec is installing two RM 2.50 Rocket Mills at Ssangyong Cement’s plants in Donghae and Yeongwol. The mills will be used to shred municipal and industrial waste to produce solid alternative fuels for use in the plant’s kilns. No commissioning dates have been released.

Poland: Sweden’s NextFuel AB plans to launch NextFuel, a briquette fuel made from elephant grass, at the 24th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP24) taking place in Katowice. The company says that its product is cheaper than and oil and coal in most markets and could be used to replace some or all of the coal normally used by a cement plant, coal plant or a steel plant. Its first operational plant is based in Austria.

The first NextFuel project is expected to reduce the CO₂ footprint of a cement factory in East Africa by 105% compared to the coal it is using at present. The cement plant also expects to cut its energy costs in half by using NextFuel instead of coal imported from South Africa. It will be able to grow Elephant Grass, the source of the fuel, next to the plant to reduce its fuel transportation costs.

Elephant Grass is a perennial tropical plant that can produce several crops in a year. Once the grass has been harvested, NextFuel says its technology requires ‘very little’ energy to produce a briquette. The company asserts that due to a quick carbon cycle and the storage of carbon, less CO₂ is released into the atmosphere when the fuel is burned than was captured from the atmosphere a few months earlier when the grass was growing. NextFuel says that annually the carbon cycle becomes negative.

After the grass is harvested, it is dried and fed into a patented reactor. This is a rotary drum, indirectly heated and operated with a low oxygen atmosphere. While inside that drum, volatile elements are separated from the grass, and the physical properties together with the energy content are transformed in less than 30 minutes. The reactor also drives out the off-gases from the grass. They are used as surplus energy to produce heat or electricity to power the facility. After the reactor is finished, the fuel is densified and turned into briquettes that are cooled. These briquettes are ready to use directly as a CO₂ negative fossil fuel substitute both in industrial and electricity production.

NextFuel plans to scale by licensing its technology to companies all around the world.

Austria: Saubermacher Dienstleistungs has ordered a XR3000C shredder from Untha for the single-stage processing of commercial and household waste at a sorting plant in Vienna. The Styrian-based waste and recycling company produces refuse-derived fuel (RDF) for the cement industry. The company’s main requirement was that the RDF should have a particle size of less than 80mm and be produced by means of a single-stage shredding process, rather than a two-stage shredding process with coarse and fine shredding. Saubermacher Dienstleistungs wanted a machine with a throughput of at least 20t/hr. It also chose the XR3000C model for its energy efficiency.

Austria: A Tec has launched a mobile version of its grinding mill. The semi mobile A Tec Rocket Mill 2.00 single is a compact version installed in a container. The mill consists of one grinding chamber with approximately a 2m diameter and 315kW installed power at the main drive. This will give roughly the half capacity of the double chamber Rocket Mill 2.50. The throughput when producing refuse derived fuel (RDF) for the main burner (90% < 50mm) is about 10 - 12t/hr.

Japan: Austria’s Lindner-Recyclingtech has entered into a sales partnership with the Japanese company Ryohshin in Toyama to strengthen its presence in the region. The Japanese recycling technology company will assume responsibility for selling Lindner shredding products to the local waste management industry.

‘The Japanese shredder market is characterised by high demand and fierce competition, with a focus on replacing older systems, upgrades and expanding existing capacities. To succeed in this environment in the long term, we choose our partners worldwide according to very strict criteria,” said Osamu Kono, the chief executive officer of Ryohshin.

Austria: A Tec has commissioned a Rocket Mill RM 2.50 for ASA at its waste treatment plant in Wiener Neustadt. The mill has a capacity of 7 – 40t/hr and is equipped with two grinding chambers, which can be independently loaded. Each one has a main drive with 315kW. Due to the grinding technology, it also has an additional drying effect of approximately 10%. The mill is designed to produce refuse-derived fuels (RDF) with an output size of 5 - 80mm from pre-sorted and shredded household and commercial waste. It was principally built at A Tec’s plant in Eberstein.

Austria: UNTHA Shredding Technology is currently working on proposals for more than 250 global prospects, eager to reap the benefits of its innovative new XR-C waste shredder. European orders in the last six months stand at Euro5m, with Holcim and SITA the most recent clients to invest in the machine.

The robust XR Cutter is able to produce high-quality solid recovered fuel (SRF) in a single pass, with double the output per tonnage of competing machines. Input material can include bulky untreated waste. When comparing like-for-like tonnages, the XR uses 50% less power consumption than traditional static electro-hydraulic shredders.

The power savings are due to UNTHA's new high-torque, slow-speed 'Eco Drive' concept. Modern water-cooled synchronous motors work continuously without overheating, ensuring minimal disruption and downtime. This also keeps running and maintenance charges minimal, with typical wear costs significantly less than Euro1/t.

"The beauty of the XR machine is its flexibility," said Peter Streinik, UNTHA's head of shredding solutions for waste. "The cutting concept is completely configurable, enabling alternative fuel producers to manufacture SRF with a homogenous pre-determined particle size of 100 - 400mm, or a precise SRF with a 30mm fraction or less. Load-dependent speed controls also enable the XR's RPM and torque to be adjusted and optimised, in order to achieve throughputs of up to 70t/hr."
