An important step in the acceleration of a circular economy, Selenis has scaled up its production of PETG resins with incorporated recycled content.
Now at full production volumes, the Eco Series was commercialised in October 2019, providing a sustainable version of Selenis’ product portfolio with up to 50 per cent post-consumer recycled content.
The Selenis process recovers monomers through chemical recycling. Glycolysis is used to break-up PET waste and reduce it to its polymer building blocks: monomers. Next, they are reintroduced to the value chain as recycled polyester raw materials.
Prior to polycondensation, the co-monomers are subjected to a fine filtration process to remove impurities. During polycondensation the final IV and properties are obtained.
NatureWorks’ new Ingeo 3D700 shown to provide significant reduction in warping, minimizing print failures.
A PLA biopolymer specially designed for large format additive manufacturing that boasts a significant reduction in warping that minimizes print failures is newly available from NatureWorks, Minnetonka, Minn. Moreover,Ingeo 3D700 has been evaluated by multiple global ‘industry partners’ for use in large-format fused filament fabrication (FFF) in the form of a monofilament, and direct resin-to-print processes in the form of resin pellets with positive results. This has included a shrink rate less than 0.25% in printed parts and obtainable lower print temperatures due to optimized melt viscosity and microstructure.
In large-format printing, the higher rate and volume of polymer deposition can quickly result in excessive warpage with materials such as ABS, or significant shrinkage as with some polyolefins or even some general-purpose PLA grades. This can result in failed prints as warping pulls the part away from the print bed or causes layer separation. With the longer print times and higher-volume material use in industrial applications, failure during production is costly. By controlling the polymer-microstructure, the resulting amorphous PLA grade, Ingeo 3D700, has a low material shrink rate which is critical for reducing warpage, improving gap fill and adhesion, and ensuring successful prints.
Company is studying feasibility of securing scrap feedstock for plant in Stenungsund, Sweden.
Vienna-based Borealis says it has initiated a new project to secure an increased supply of chemically recycled feedstock to produce base chemicals and polyolefin-based products. A feasibility study is now underway for a chemical recycling unit to be established at the Borealis production site in Stenungsund, Sweden, says the firm.
The study is being funded in part by a grant awarded by the Swedish Energy Agency and is being carried out with project partner Stena Recycling, which is based in Sweden. “Provided a successful feasibility study and final investment decision, operations are expected to begin in 2024,” says Borealis.
Pure Loop has commissioned an ISEC evo 302 machine at its Ipswich, USA facility for potential buyers to test their own material, a service already offered by its sister firm Erema in Ansfelden, Austria.
The shredder-extruder combination is built in modules so it can be configured to meet different requirements for degassing, filtration and other performance parameters.
“The USA and Canada are important markets for the in-house recycling segment that we serve with our local sales partners,” said Manfred Dobersberger, managing director of Pure Loop. “With this machine that our American customers can also use to carry out non-binding test runs with their material, we confirm the significance of this market.”
Trillium Renewable Chemicals to advance technology for production of such feedstocks as acrylonitrile for use in ABS and other plastics.
A new start-up company, Trillium Renewable Chemicals, Birmingham, Ala., plans to make chemicals from renewable feedstocks, including acrylonitrile for ABS with a net-zero footprint according to CEO Corey Tyree. “This technology can improve supply chain security and GHG (greenhouse gas) footprint of ABS makers,” he said, as one example.
The new start-up was jointly created by Belgium-based venture capital and investment firm Capricorn Partners and Southern Research (SR), an independent nonprofit, scientific research organization with more than 400 scientists and engineers working across three divisions: life science, engineering, and energy & environment. Headquartered in Birmingham, with additional laboratories and offices in Frederick, Md., and Houston, SR supports related industries with independent research on behalf of commercial and government clients, objectively assessing new technologies and providing process development support. It also pursues entrepreneurial and collaborative initiatives to develop and maintain a pipeline of intellectual property and innovative technologies that positively impact real-world problems.
Steer’s compounding technology for rice resin in Japan
In a bid to push for environment-friendly alternatives to oil-based plastics India-based extruder firm Steer Engineering has announced that its patented technology is now being deployed for the development of biomass resin. It adds that it recently supplied three units of its Omega 60 class extruders to Biomass Resin Holdings in Japan.
The extruders help accelerate development and commercialisation of compound materials of inedible rice with polyolefin resins, called “Rice Resin”. Using these compound materials, products such as trash bags, shopping bags, cutlery (plastic utensils), and toys, can be manufactured for end customers. In the long term, these products significantly reduce plastic waste through environment-friendly polymer.
Spain’s Valencian Innovation Agency (AVI) has funded a project that aims to use renewable sources to develop a biodegradable packaging system that includes barrier labels and antioxidant additives from avocado waste. The Guacapack Project plans to extend food shelf life by 15 per cent.
When avocados are processed for use in food items, the amount of waste produced can account for more than 45 per cent of the total weight of the avocado. In order to make use of this waste and extend the shelf life of prepared products, Aimplas, the Plastics Technology Centre, is to develop the project alongside lead company ITC Packaging and the Universidad de Alicante’s research group on Polymer and Nanomaterial Analysis.
The label will feature an oxygen barrier function that prevents the oxidation of food and extends the shelf life by 15 per cent. The incorporation of natural antioxidants extracted from the avocado itself also helps reduce the use of synthetic preservatives.
Swiss integrated machinery firm Maag Group says it has supplied its latest the art x6 class melt pump technology for the first fully integrated sugar-to-PLA (polylactic acid) plant in China. The plant is based on a Sulzer technology and key equipment for converting lactide into PLA. The lactic acid and lactide production is made from sugars (in this case won out of locally grown corn).
Maag says not only is the plant reducing the carbon footprint because of using plant-based resources instead of hydrocarbons, but by using its x6 class gear pump technology, the specific energy requirement is optimised furthermore.
MAAG Group’s pumps are used in the polymerisation reaction stage, making sure that the efficient Sulzer SMR reactors are working smoothly in all operating conditions. But they are also used in the devolatilisation stage, where, a minimum level is required when unreacted lactide is removed from the PLA melt to achieve a good product quality. In the last stage, Maag’s melt pumps are used to build up the necessary pressure to process the melt through the downstream equipment, up to the underwater pelletiser.
A key feature of the melt pump technology is the reduced back-flow to lower the energy consumption. The x6 class melt pump helps to save up to 50% energy and reduces material recirculation in the pump of about 50%.
While the reduction of 50% of energy is possible in exceptional cases and in extreme operating conditions only, the trend is true for all the applications when the x6 class technology is used.
Human necessity and intellect can extract anything from the plentiful resources available for our use on Earth.
We are engulfed by the inexhaustible clean-energy sources around us- the Sun, the Earth, the wind, the ocean, plants, atoms. However, the problem lies in the fact that technology and financial assistance needed for tapping the green energy forms, have lagged behind than expected.
But the need to find Energy forms for a hungry population cannot be jeopardized by this inability to exploit more. Therefore, we continue to test and conduct researches in order to discover an energy resource that can equally sustain the world’s insatiable and destructive appetite for energy as well as maintain the Nature’s critical balance.
Nuclear power has the capacity to facilitate this transition for world’s energy supply toward carbon neutrality.
