    Incineration of solid waste produces millions of tonnes of waste fly ash in Europe each year, that most commonly ends up in landfill. But this ash often contains significant amounts of precious metals, such as zinc. A unique method developed by researchers at Chalmers University of Technology, Sweden, can now help extract these precious metals, potentially leading to reductions in environmental pollution, landfill and transport.
    During waste incineration, the released flue gases are purified and the small particles present are separated, leading to the formation of fly ash. This fly ash contains toxic substances, such as dioxins, and so is normally classified as hazardous waste and landfilled. But it also contains valuable metals, such as zinc, which are thereby lost.
    But a new method from Chalmers University of Technology, tested at pilot scale and detailed over several years of research, involves treating this waste with an acid wash, also separated from the flue gases, to separate the zinc from the fly ash. The zinc can then be extracted, washed and processed into raw material. 
    “In our pilot study, we found that 70 percent of the zinc present in fly ash can be recycled. The zinc is not extracted as a pure metal, which would be a much more intensive process, but instead as a zinc-rich product, which can be sold to the metal industry and processed further in currently existing industry production lines,” says Karin Karlfeldt Fedje, Associate Professor at Chalmers University of Technology, and researcher at the recycling and waste management company Renova AB.

    Ash Turned Into Useful Material
    In further refinement to the method, the researchers have been able to significantly reduce the level of toxicity.
    “After extraction, we incinerate the residual ash again to break down the dioxins. Ninety percent of this is then turned into bottom ash, which can be used as a construction material, for example,” explains Karin Karlfeldt Fedje.
    Internationally, the prevalence of waste incineration is varied, but the need to handle large amounts of ash after the process is widespread. In Sweden, incineration of household waste in waste-to-energy plants is common, and results in around 250,000 tonnes of fly ash every year that could potentially be treated in this way. The rest of Europe accounts for around ten times that amount.  
    Although it is hard to estimate how many tonnes of zinc are currently lost through landfill in Sweden and beyond, the method developed by the Chalmers researchers can be of great interest to all waste management actors. It offers great potential for recovering these metals in a relatively simple way and could have a significant impact on the profitability of waste incineration, as well as its role in the circular economy.
    “The technology for extracting zinc from fly ash could have several positive effects, such as reducing the need for mining virgin zinc raw material, lower levels of toxicity in the ash, and greatly reduced landfill contributions. It can be a vital contribution to society's efforts towards a more circular economy,” says Sven Andersson, Adjunct Professor at Chalmers and R&D Manager at flue gas cleaning supplier Babcock & Wilcox Vølund AB.

  • CASE Wins Prestigious Good Design Award for Design of “Project Zeus”

    CASE Wins Prestigious Good Design Award for Design of Project Zeus

    CASE Construction Equipment has earned a 2020 Good Design Award from the Chicago Athenaeum Museum of Architecture and Design and Metropolitan Arts Press for “Project Zeus”: the CASE 580 EV (electric vehicle) backhoe loader — the world’s first electric backhoe. The award recognizes “the most innovative and cutting-edge industrial, product, and graphic designs produced around the world."
    This is the third CASE design to win in four years. CASE G Series wheel loaders were honored in 2017, and the methane-powered concept wheel loader, Project Tetra, won in 2019.
    The award recognizes the matching of CASE brand heritage via a product line that originated in 1957 with sustainability anchored in both clean operation (no emissions/elimination of diesel fuel) and the sharp and clean design of the machine itself. “Project Zeus” was also noted for its innovative lighting/backlighting design elements; its rugged and clean lines and contouring; a specialized metallic “Power Tan” color scheme; and a modern and intuitive user experience that combines traditional backhoe operation with specialization related to electrification.
    “The theme is born from combining the essence of CASE heritage and the mission of sustainability into a clean and simple design,” says David Wilkie, head of the CNH Industrial Design Center. “It is extremely practical and built around function while delivering distinctive design elements that communicate strength and progress. From the lighting to the color and the way that the operator interacts with the machine. “Project Zeus” represents the sustainability and forward-thinking of our industry.”    
    “The electrification of construction equipment, and the focus on sustainable power sources and machine ownership/operation, are all driving forces for public and private fleet owners around the world,” says Leandro Lecheta, head of construction — North America, CNH Industrial. “The CASE 580 EV accomplishes this through the elimination of emissions, diesel and other fluids and components, while also delivering a machine design anchored in trusted CASE backhoe performance — and our CNH Industrial Design Center tied it all together with a clean, modern aesthetic that stopped people in their tracks when we introduced the machine at CONEXPO 2020.”
    From an operational perspective: the power and performance of the CASE 580 EV is equivalent to diesel-powered backhoes in the CASE product line and provides considerably lower daily operating costs while also producing zero emissions — a motivating factor for utility and government contractors incentivized to work with equipment that leverages alternative fuels and lowers emissions. City governments and municipalities will also benefit from the elimination of emissions for working in urban environments and close to other buildings/people, as well as the reduced noise generated by the equipment. The machine has since gone on to win numerous industry awards and accolades as one of the best and most important construction equipment introductions of 2020.

  • Puck Rolls Out Long Reach Agi: First-Of-Its-Kind Agitation Trailer

    First-Of-Its-Kind Agitation Trailer

    Stirring up the nutrient application market, Puck announces it will officially be launching its most compact and versatile agitation trailer to date–the Long Reach Agi. Designed for the evolving needs of nutrient applicators and liquid transfer operators alike, Long Reach Agi is fitted with the industry's first-ever telescoping boom. 
    "This is one of our most ambitious designs yet. The truly unique qualities of the Long Reach Agi add new capabilities that customers can utilize to meet nearly every agitation demand on the job site," Jeremy Puck, CEO of Puck Enterprises. "Long Reach Agi completely shifts the old status quo of liquid agitation towards a new mindset: how can I get more done with less."
    Designated as Agi 1708 X, Puck developed the Long Reach Agi to be the end-all-be-all solution for flexible agitation needs. This revolutionary piece of equipment can mix a wider variety of pits and slurry stores without the need to crane in an agitation boat. By freeing up the need for additional equipment on-site, applicators save time and money. 
    To accomplish these objectives, the company equipped Long Reach Agi with the first-ever telescoping boom. This game-changing boom has an unprecedented length of 50 feet–once its two stages are fully extended. The incredible boom span means that Long Reach Agi lives up to its name by having a maximum slurry store clearance height of 25 feet and a mixing reach of up to 25 feet. The boom's intuitive telescoping functionality allowed Puck to create an overall compact trailer design and machine footprint. When retracted, the two boom stages contract to a length of just 15ft. 
    "It's an ideal balance of functionality and performance," added Luke Potthoff, General Manager of Puck Enterprises. “Customers can expect to find that Long Reach Agi is built to our uncompromising standards and will be an indispensable piece of equipment.”
    Advantages of Long Reach Agi don't stop there. The boom turret has a 105-degree rotation of moment. Agitation nozzles boast 180 degrees of movement and have independent hydraulic gate valves. The tailer's outflow gate makes the process of switching from agitation to transfer mode easy and doesn't require operators to shut down the engine. An auxiliary hose reel is mounted to the trailer for added hose availability–if needed. 
    Puck also focused on making maintenance more manageable and more streamlined. Better placement of greasable end pins allows for better access during routine upkeep. Boom cable carriers feature plastic disks that aim to reduce the chances of having carriers size up. Nylon skid pads throughout Long Reach Agi increase durability and don't require greasing (reducing maintenance costs). 

    Additional specifications include:

  • Precious Cargo: Strengthening The Vaccine Cold Chain From Start To Finish

    Strengthening The Vaccine Cold Chain From Start To Finish
    Real-time monitoring capability is especially important with pharmaceutical products, because there is no visible indication when a pharmaceutical product has deviated from a set temperature. Data can provide confidence that the efficacy and integrity of the product have remained intact, and that the medicine will be safe and effective for patients.

     

    The development of a COVID-19 vaccine is in high gear, with the global pharmaceutical industry racing to deliver a viable medicine to slow the spread of the virus. Getting this vaccine to billions of people all over the world will create never-before logistical challenges.
    Earlier this year, Trane Technologies’ leadership team created a dedicated global task force to help strengthen the cold chain in anticipation for a COVID vaccine. The team has been engaging pharmaceutical and transport companies, policymakers, regulators and other industry partners to discuss the complexities and potential challenges of the global distribution of a temperature-sensitive vaccine.
    “The global community has been working tirelessly to help stop the spread of COVID, and we know that Thermo King® can contribute in a meaningful way,” shares Francesco Incalza, president of Thermo King Europe, Middle East and Africa. “While there remain many unknowns, our team is focused on identifying potential risks in the cold chain and proactively finding solutions so that our customers can quickly and safely get the vaccine into the hands of our healthcare professionals.”

    Complex Logistics With Precious Cargo
    One of the key complexities in the pharmaceutical supply chain is the need for refrigeration technology. Vaccines require precise temperature control to ensure the product remains stable. Many of the COVID-19 vaccine candidates need to be stored and transported at sub-zero temperatures. And this temperature control needs to be maintained for the entire journey, including during storage and transport from the point of manufacture to the point of use. This is known as the cold chain.
    If there is a break in the cold chain, and a temperature-sensitive product falls outside of the required temperature range, the result could be the loss of an entire load of high-value, life-saving medicine. That is why maintaining the cold chain and protecting these products is so important.
    “Temperature control will play a critical role in safeguarding a vaccine,” Karin De Bondt, president of Thermo King America confirms. “Given the urgent, global need for a COVID-19 vaccine, we need to be prepared to meet obstacles in the cold chain head-on, and ensure that the medication is protected from the moment it leaves the manufacturer to when it arrives to the patient.”
    Safeguarding against breakdowns in the cold chain can quickly become a very complex operation from a logistics standpoint. And this is made even more complex when you consider the circumstances around a COVID-19 vaccine. Imagine devising a logistics plan to deliver as many as 15 billion vaccines globally as fast as possible, not knowing exactly where the manufacturing points will be, the volume of doses, or how cold the vaccine will need to be kept.
    One vaccine in development will require a constant temperature of -70 degrees Celsius (-94 Fahrenheit) - and that temperature will need to be maintained while the vaccine travels thousands of miles between manufacturing locations, trucks, planes and consolidation facilities, and then on to the final point of administration to a patient at a hospital or clinic. This must all happen without delay, across multiple touchpoints and with many parties coordinating handoffs.
