The multitine grab excels in terms of exceptional load-bearing capacity, resistance and durability.
Liebherr, a European construction and scrap handling equipment manufacturer, has launched the multitine grab GMM 50-5.
According to a news release from Liebherr, the multitine grab excels in terms of exceptional load-bearing capacity, resistance and durability. The equipment features a comprehensive portfolio of buckets and a wide selection of optional equipment, meaning diverse materials can be handled efficiently and economically in recycling and scrap handling. The GMM 50-5 is available for material handlers with an operating weight of between 35 to 55 metric tons.
The components of the GMM 50-5 are made of sturdy cast steel as well as low-wear, high-strength steel sheets. The consistent use of high-quality materials guarantees extreme stability and resistance for the toughest applications and material handling scenarios, and the special shape of the tine support and the buckets was developed based on state-of-the-art calculation and simulation software.
The company says it paid special attention to maximizing service life in the design phase. To split the high torque, the slewing drive, for example, was equipped as standard with two motors. Both rotary transmission and the reinforced slewing drive are sealed multiple times to give maximum protection against external factors such as dust and water.
Large and flow-optimized oil ducts ensure fast work speeds and efficient machine operation. The sealed, anti-twist piston rod protection for hydraulic cylinders is also included with the grab as standard. The latter comes with new cylinder kinematics, which guarantees a long-lasting and good closing mechanism when the tines become worn.
As the lubrication points are arranged ergonomically, the GMM 50-5 is supplied with the lubrication in a short space of time. Perfect tolerances and generously dimensioned bearing surfaces lead to a smooth interplay of the individual components, according to the company.
Due to the optional motor and hose protection, damage to rotary motors and hydraulic lines is minimized. An optional central lubrication system assumes regular, automatic lubrication of all central points. The GMM 50-5 can be equipped with shackles to protect magnetic plates. The tines can be equipped with a reinforcement set of wear-resistant sheets.
The GMM 50-5 is designed especially for optimal grabbing of mixed and shredder waste as well as chippings or shavings with content of up to 1.10 cubic meters. The arrangement and shape of the tines are optimized for perfect penetration and holding of bulky, loose material.
There is a choice of three different tines for handling diverse materials. The version with open tines can handle large-size and bulky scrap objects. The version with semiclosed tines handles medium-sized, mixed materials and shredding waste. Small, fine materials and chippings or shavings can be handled most effectively with closed, heart-shaped tines.
The company says the results of an independent carbon dioxide equivalent life cycle assessment show expected emissions savings were 60 percent.
Vancouver-based Northstar Clean Technologies, Inc. has announced the results of a second independent carbon dioxide equivalent (CO2e) life cycle assessment. The LCA, completed by Burgess Environmental Ltd. and based on modeling from the front-end engineering design (FEED) completed by BBA Inc., assessed the impacts and benefits of reprocessing asphalt shingles at Northstar’s Calgary Empower Facility. These findings were compared with the impacts and benefits related to the disposal of discarded or defective asphalt shingles in landfills and virgin production of asphalt shingles.
The assessment, Northstar says, found that the Calgary Empower Facility will have lower CO2e emissions than landfilling and virgin production.
According to Northstar, the facility would produce 77 kilograms of CO2e per metric ton of feedstock. Virgin production and landfill disposal, on the other hand, was found to produce a combined total of 195 kilograms of CO2e per metric ton of feedstock. The company says net savings come to a total of 117 kilograms of CO2e per metric ton of feedstock or about 60 percent in savings.
Net estimated CO2e emissions savings are expected to be in the range of 3,500 metric tons to 4,700 metric tons of CO2e per year depending on production volume.
In addition, each metric ton of feedstock processed is expected to reduce water consumption in the range of 18,000 cubic meters to 24,000 cubic meters per year and avoid land disturbance in the range of 13,800 square meters to 18,400.46 square meters per year.
“The completion of the LCA is another step toward the development of our Calgary Empower Facility and builds on the momentum of the completion of the FEED design and awarding of non-dilutive grant funding from Alberta Innovates. This analysis quantifies how our operations in Alberta can support our customers and industry partners in delivering circular and ‘green’ renewable asphalt produced with significantly lower carbon intensity,” says Aidan Mills, president, CEO and director of Northstar.
Northstar says future revenue and margins from carbon credits could potentially arise from CO2e emissions benefits depending on the regulatory and legislative framework.
Construction on the Calgary Empower Facility is slated to begin in the second half of 2022 with operations beginning in the first half of 2023 according to Northstar’s website.
Gateway will supply 10 million tires annually to Wastefront’s Sunderland, England, facility.
Wastefront AS, a waste tire recycling company based in Oslo, Norway, has announced an agreement with Dubai-based tire company Gateway Resources guaranteeing the complete supply of end-of-life tires (ELTs) for Wastefront’s Port of Sunderland plant in England.
“Our agreement with Gateway Resources is a key part of our mission, tackling the scourge of ELTs at scale and pace, whilst creating a truly circular economy in tandem,” says Vianney Valès, CEO of Wastefront. “We cannot continue with our dependency on new and scarce materials whilst continuing to burn existing materials with devastating and immediate environmental consequences. To solve the problem, Wastefront is proposing a solution that is both circular and at scale.”
Backed by energy giant Vitol, Wastefront secured planning permission in January to build the $1.26 million tire recycling plant in Sunderland, which is set to be commercially operational by 2024. Once at full capacity, the plant will manage 20 percent of the United Kingdom's total ELTs through processing 80,000 metric tons annually. Gateway Resources will supply Wastefront with about 10 million tires every year.
Additionally, this figure corresponds to a substantial volume of the total tires currently exported from the U.K. abroad yearly. Today’s announcement will play a crucial role in eliminating the U.K.’s waste tires export altogether, by creating a local solution to a global problem. Gateway Resources will work in conjunction with suppliers to supply ELTs to Wastefront.
Wastefront says the announcement also paves the way for overdue domestic progress on cement kiln burning. Though the burning of ELTs in cement kilns was a step forward for the U.K., creating crucial supply chains for ELTs, it remains one of the most polluting forms of manufacturing. This is because burning tires in cement kilns pollute the air with dangerous chemical particles, aromatics and CO2.
Wastefront says it will use commercial operating technologies to convert the ELTs received from Gateway into commodities, including biofuels and recovered carbon black. These are then reintroduced into the supply chain and utilized in processes such as alternative fuel or raw materials to produce new tires or other products. Wastefront’s recovered carbon black will result in an 80 percent reduction in total emissions by replacing virgin carbon black in tire production. The company says tire manufacturers have shown interest in purchasing this recycled material.
Following the supply agreement for the Port of Sunderland plant, Wastefront and Gateway have also signed a memorandum of understanding to work together toward implementing an additional ELT supply agreement for a potential Wastefront plant in continental Europe, which is under review.
“We have long been engaged with regulators to find a local, more sustainable solution, to replace our existing shipping routes for ELTs across the world,” says Soham Khemka, Gateway Resources director. “Wastefront is the first player to tackle the ELT problem at scale across Europe, with the significance of their plans having a massive impact on the industry. Wastefront is going head-on with the necessary evils of exporting waste, finally rendering it unnecessary and truly building a circular economy both at home and abroad.”
The contractor will provide engineering, procurement and construction services.
S&B Engineers and Constructors has signed a multiyear master service agreement to provide engineering, procurement and construction (EPC) services for New Hope Energy’s plastics pyrolysis unit. This partnership will initially focus on New Hope Energy’s expansion in Tyler, Texas, which S&B says will add 420 metric tons per day of capacity to convert plastic waste to chemical feedstocks in the exiting facility.
With this expansion, S&B says the Tyler plant will be able to divert more than 300 million pounds of plastic waste from landfills annually. According to S&B, the project represents a long-term alliance between the two companies.
“We look forward to the long-term program and collaborative partnership with S&B and its highly developed supply chain as we grow our advanced chemical recycling systems to create a circular economy that moves the U.S. toward a sustainable future,” says Ron Nussle, chief operating officer and president of New Hope Energy.
Full EPC services will be provided by S&B using the Lummus New Hope plastic pyrolysis technology to process plastic waste into renewable chemical feedstocks.
“We’re excited to partner with New Hope to boost its advanced recycling capacity to create solutions for plastic waste,” says Ray Sherman, president of S&B’s energy transition, power and industrial business unit.
Can maker and Manna Capital will build aluminum melt shop and rolling mill in New Mexico.
Ball Corp. and Louisville, Kentucky-based Manna Capital Partners have announced an alliance in which Manna will construct and operate a recycled-content aluminum can sheet rolling mill and melt shop in Los Lunas, New Mexico.
Ball, based in Westminster, Colorado, will enter into a long-term supply agreement and also intends to take a minority equity position in the mill, says the maker of aluminum beverage cans and bottles. Manna, which describes itself as a minority-owned business enterprise and investment firm, says the announcement demonstrates both companies’ “commitment to creating a more robust and sustainable domestic supply chain for the growing beverage packaging market.”
Global aluminum can demand is expected to increase significantly by 2030, Ball Corp. says, with North America estimated to account for a sizeable part of the growth. Since 2016, industry demand for beverage cans in North America has grown 24 percent from 107 billion units to approximately 133 billion units in 2021, adds the firm.
While the industry in North America sometimes imports aluminum can sheet coils to meet demand, “alliances like this one will allow Ball and its key customers to access more domestically produced aluminum can sheet,” the firm says.
“At Manna, we are always looking for new ways to invest in companies that are doing good for the planet and people, while improving opportunities that support minority owned-business enterprises,” says Ulysses L. “Junior” Bridgeman, managing partner of Manna Capital Partners. “We look forward to partnering with Ball, a leader in the beverage packaging industry, to improve supply chain efficiencies through domestic production of more sustainable aluminum."
Ball Corp. President and CEO Dan Fisher says, “Further increasing recycled content in our products is key to boosting our sustainability and securing domestic supply of our key raw material. This alliance complements the significant manufacturing investments Ball has made across the Southwest United States since 2020 to meet growing demand for sustainable beverage packaging, and we look forward to teaming up with Manna and its management team to help create a truly circular economy for aluminum can sheet, bring skilled jobs to the region, and help our customers meet their sustainability commitments.”
