Krall Kunststoff-Recycling proves that the CO2 equivalents of their PMMA, PET and PC regrinds are up to 95% lower than those of corresponding virgin materials. As a pioneer in the recycling industry, Krall Kunststoff-Recycling can now prove that the CO2 equivalents of the PMMA, PET and PC regrinds produced there from post-industrial plastic waste are up to 95% lower than those of corresponding virgin materials. One key to this particularly high contribution to sustainability is the extensive use of solar energy generated in-house. The calculation of the carbon footprints, which was carried out at a renowned institute, was based on the international standards DIN EN ISO 14040 / 14044 on ”Life Cycle Assessment” and DIN EN ISO 14067 on ”Carbon Footprint of Products”. Company founder and managing director Markus Krall comments: ”The documentation of greenhouse gas savings gives our customers and partners a valuable aid for proving and evaluating their own environmental measures. The high values that apply specifically to our regrinds make a particularly positive contribution to this.” Variety of certifications strengthens

cutting mills with force feeding device for max. throughput at size reduction. (PET bottles, plastics bottles, canisters, packing materials, containers,...) TO INCREASE THE THROGHPUT OF A GRANULATOR A SCREW CONVEYOR IS UTILIZED FOR A TECHNICALLY NEUE HERBOLD Maschinen- und Anlagenbau GmbH, D-74889 Sinsheim-Reihen offers a large range of machines and plants for size reduction and recycling of plastics scrap, from production or waste collection. To increase the through-put rate of a granulator used for size reduction of loose, unpressed plastics a force feeding technique was developed. A screw conveyor is utilized for a technically optimized material feed. Via conveyor the material is fed in the feed hopper. The transport to the grinding chamber is now no longer only based on the principle of gravitation - in fact the material is now fed to the grinding chamber by one / or more vertically assembled screws. Depending on the required granulator size the number of screws, the rotation speed as well as the drive capacity can vary. A transport screw equiped with a load-dependent control as well as a frequency converter prevents

The Russell Finex Separator proves efficient and cost-effective for industrial tools and minerals company Diaber, a Belgian company specializing in industrial tools and minerals, has optimized its glass recycling process with the help of the Russell Finex Separator. Diaber uses Reglass Glasgrit, a product made from recycled materials, as a media in its sandblasting machines. To ensure optimal performance, the glass grit must have a defined particle size range without oversized or undersized grains. Previously, Diaber relied on sieves and separators to remove unwanted particle sizes. However, when setting up a new production facility, they turned to Russell Finex for an efficient and cost-effective solution. The Finex Separator proved to be the ideal machine for Diaber, enabling them to sieve recycled glass at a high capacity before cleaning, grinding, and packaging. This upgrade improved productivity and cost-effectiveness compared to outsourcing the glass sieving process. With the Finex Separator, processing 2-3 tonnes of glass per hour, outperforms traditional separators

Innovative all-rounder for measuring all types of bulk materials that combines all important features of a reliable measurement technology and is additionally very user-friendly The significance of the gear mechanism is not to be underestimated. Many a “simple” type of component can soon become a problem if it’s not working reliably. In situations where level monitoring is required, costly events such as over filling of the silo can be avoided. Sensors have to be designed with a high degree of compatibility for processes, so that they can be seamlessly integrated into installations ensuring the optimal solution. All-rounder single rod probe We are often asked whether there is one measurement principle, which works reliably in all bulk solids applications? Is there one sensor that can cope with low bulk density, bridging, caking, abrasiveness, corrosion, high tension and leverage forces, high and low process temperatures and pressures, low and fluctuating dielectric value as well as being able to offer a short reaction time? To date, the answer to this question has been “no”, there has not been any one measuring principle to solve

Dietmar Dieing, Sesotec Vice President Sales Plastics, in an interview about insights from the K 2022 and SOLIDS 2023 trade fairs as well as an outlook on FAKUMA 2023. What bulk solids technologies trends? Mr. Dieing, what trends did you notice at the K 2022 plastics trade fair and the SOLIDS 2023 trade fair for granulate, powder and bulk solids technologies? At both trade shows, it became clear that sustainability, circular economy, digitalization and process optimization are becoming increasingly important for the various industries. At K, for example, many companies presented solutions to improve the production and processing of plastics and to optimize recycling. With our trade show motto ”Economy meets Ecology” we have hit the bullseye, because we provide answers to the questions that move plastics manufacturers, processors and recyclers: How can circular and at the same time highly efficient production be achieved; so that economy, sustainability and environmental protection go hand in hand? How does Sesotec contribute to building a Circular Economy? As a supplier of foreign object detectors, material analysis
