The manufacturer of HDPE containers, drums and bottles, AST, is investing in a new centre of competence with a complete plastics recycling line. As a project partner, they are relying on Lindner. Erndtebrück (Germany), March 2021. The European manufacturer of plastic containers, drums and bottles, AST, has set a long-term target to increase the amount of recyclates used in its products and aims to supply their own ‘raw materials’. For this reason, AST is investing in a new centre of competence with a complete plastics recycling line to process post-industrial and post-consumer HDPE (high density polyethylene). As a project partner, they are relying on the expertise and a system solution from Lindner. Since 1977, AST Kunststoffverarbeitung GmbH has been producing high-quality packaging with approval for dangerous goods in Erndtebrück, Germany. Today, the company is a European market leader when it comes to plastic containers for chemical products or food, and it is working hard to increase the sustainability of its products by using recyclables. If you ask AST what the new centre of competence is all about, the complexity of the topic quickly becomes

When detecting fill and limit levels, sensors with high compatibility for different process vessels offer optimal support for a smooth process. Level detection at high process temperatures for wood power plants When detecting fill and limit levels, sensors with high compatibility for different process vessels offer optimal support for a smooth process. The material to be checked can be of very different properties depending on the processing stage and make different demands on the measurement technology to be used. The rotation principle for point level detection in silos and material processing processes has proven itself for many decades. Even under extreme conditions. An energy technology company was looking for modern, high-quality technologies for point level measurement in order to optimally equip its wood-based electricity systems. The wood gas is converted into electricity after gas processing in a combined heat and power plant. ° When things get hot. Rotary paddle detectors when generating electricity using biogenic solid fuels Rotary paddle detectors are known for their easy-to-use functional

In future, RHEWUM will use environmentally friendly water-based paints when painting its machines. This not only benefits our environmental balance (VOC balance), which can be reduced to up to 78%. In this way it is now possible, among other things, to significantly reduce the use of diluents. A high quality and resilient corrosion protection is of course guaranteed. And that even with lower layer thicknesses. In addition, the drying temperatures can be halved from the current 80 ° C to approx. 60 ° C and drying times from four to two hours. Would you like to find out more about RHEWUM and its products? Contact us, we look forward to your questions.

If inhouse waste and heavily contaminated post-consumer waste are added to the production process, foreign particles of various sizes and quantities are introduced into the melt flow. These have to be filtered out efficiently to ensure a consistent and high quality of the end product. At the same time, however, melt filtration must not have any disturbing influence on the production process. Several filtration systems require a production interruption when changing screens, cause process disturbances due to pressure spikes or even generate particles if deposited material comes off during screen changes. Disturbance-free production process thanks to permanently constant conditions In contrast, with the unique Gneuss Rotary Technology, the conditions in the melt flow are permanently constant, i.e. the pressure drop across the screen, respectively the amount of contamination on the screen, is kept constant, so that the line can always be operated in the optimum range. This is achieved by the rotating movement of the filter disk, with which the screens are transported through the melt channel. A control system ensures that the screen contamination

New pressure-resistant GKM screening machine KTS-VP2 600 for control screening in pneumatic conveying streams The majority of raw materials from various industries exist in the form of powder or granules, these are generally stored in transport or storage silos. As it is possible for the raw materials to contain impurities, agglomerates, or tramp material the unfortunate consequences of this are them finding their way into the process flow which in turn results in a loss of production due to machine & system emptying and clean down. The implication of this being – product rejection/recalls at the point when the impurities reach the end product. The use of check sifters/sieves is an effective way to police the powders & ultimately prevent these issues from occurring. As the typical transfer of such raw materials between silos or the loading and unloading of trucks is carried out by pneumatic conveying this can create an overpressure in the conveying system, this is why a gravity screening machine cannot be used for this purpose. In order to ensure smooth conveying,

Each metering line can be equipped with an individual shut-off

New recycling plant for opening up electronic waste and printed circuit boards. At the Mühlacker site in Baden-Württemberg, Germany the company MetReTec GmbH has built a new, modern recycling plant for recycling of electronic waste and circuit boards. The recycling plant is located Muehlacker, Germany, has a plant area of approx. 8000 m² and approx. 35 employees are operating the plant. A Turbo-Crusher type TQZ1200, from THM recycling solutions GmbH, is the first unit in the system and is used to shred and break up the input material. With a modern and comprehensive downstream separation system the crushed and open-up material, is separated into single-type fractions. The resulting pure materials, such as Copper, precious metals, plastics and steel are marketable materials that can be returned into the material cycle. Other material fractions that arise in this process can be refined or processed using other equipment.

What challenges and opportunities exist for recyclers, manufacturers and processors of plastics? Schönberg, March 2021 Sesotec GmbH from Schönberg recently published a comprehensive e-book on the topic of "Circular Economy" on its website. In it, recyclers as well as manufacturers and processors of plastics will find insights into the most important factors of the Circular Economy. In particular, the goal of creating a circular economy, which must be profitable not only for people and the environment but also for recyclers, manufacturers and processors of plastics, comes under consideration. The plastics industry is under pressure. Between climate change, excessive consumption of finite resources, and vast amounts of plastic waste in the world’s oceans, plastics are coming to be seen in a different light by politicians, businesses, and consumers alike. The urgency is becoming increasingly apparent: it is time to rethink plastics on a global scale. Such an overhaul must include legislation, the development of new kinds of plastic packaging, and innovative
