New process for PUR rigid foam recycling

Gocreate plastic recycling04.10.2022 | In a cooperation, Krauss Maffei, Rampf, Remondis and BASF the plastic recycling of PUR rigid foams und schließen so den Materialkreislauf. Diese Post-Consumer-Abfälle stammen von Polyurethane (PUR) Dämmstoffen aus Alt-Kühlschränken.

So that refrigerators work energy-efficiently and as little CO as possible2 cause emissions, manufacturers around the world use the insulation performance of polyurethane in almost all devices. But what happens at the end of the life cycle when the refrigerators and thus the PUR rigid foam have had their day?

The EU directive 2012/19/EU stipulates for the disposal of waste electrical and electronic equipment (WEEE) that rigid foam is produced as regrind, which has so far mainly been used for energy generation. Although 30% of the energy used in the production of PUR is recovered, the carbon is not kept in the material cycle. The four cooperation partners will change that. Using a new chemical recycling process depolymerization, a recycled polyol is obtained. This raw material is to be used in the production of PUR in order to close the material cycle.

To date, there have mainly been processes for the chemical recycling of PU that are based on industrial waste, mostly from production. They have a high degree of purity, which makes recycling significantly easier. Much more complex to handle is the recycling stream that comes from post-consumer waste comes from, because these are heavily contaminated with foreign substances such as other types of plastic and metals.

The aim of the development is an industrial process that produces high quality recycled polyols supplies, which are comparable to polyols obtained from fossil primary raw materials.

Reading tip: Reaching CO2 neutrality with plastic recycling

The chemical testing and qualitative assessment of the recyclate obtained is carried out by the BASF Polyurethanes GmbH in Lemfoerde. The basic requirement for the recycling project is that the collection and dismantling of the old refrigerators and freezers work well, for which the Remondis Electrorecycling GmbH in Lünen. the Rampf Eco Solutions GmbH in Pirmasens makes its experience in the chemical recycling of polyurethane and PET residues available for the project. Krauss Maffei contributes with its technologies for the production and recycling as well as the sustainable use of plastics at the end of the life cycle.

Compounds of high-performance materials from scrap tires

22.08.2022 | Tire Recycling Solutions SA (TRS), Préverenges, uses Buss' Compeo technology to implement its Intelligent Compounding concept to convert powder products obtained from old tires into innovative and high-quality compounds for industry.

The high-performance materials are manufactured using a proprietary process in which TPE / TPU based plastics be compounded with recycled rubber powder. The range of possible applications is large: They can be found in seals, logistics, Automotive engineering, construction industry, shoe industry and 3D Print.

Compeo compounding technology is a unique combination of high-performance, low-shear mixing and a conical discharge pump (CDP) for pressure build-up. With Elastomer know-how and the possibility of pilot-scale production runs on the Pratteln campus, Buss supported TRS in the development and evaluation of the innovative products up to the commissioning of their compounding plant.

Both companies are working closely together to expand the product platform worldwide and to install further compounding systems under TRS license. The associated disposal of old tires makes ecological sense, and every year more than 1,5 billion worldwide. attack. In some countries, these are still disposed of in landfills and are often incinerated, releasing toxic smoke and pollutants into the environment. Mixing the obtained powder into TPE / TPU plastics reduces this waste. 

Shredding, washing, sorting for plastic recycling

Lindner plastic recycling

25.07.2022/XNUMX/XNUMX | As a specialist in plastics recycling, Lindner is presenting a new system solution which directly Post-consumer hard plastics processed in injection molding. Plastic should be kept in the cycle for as long as possible and is increasingly being recycled in the Food industry be used. The perfect coordination of the upstream processes Shredding - Washing - Sorting. For this purpose, Lindner offers complete solutions with which the individual process steps for the processing of hard plastics, foils and PET can be efficiently optimized.

The shredding of old plastic is at the beginning of the plastic recycling process. At the new one Jupiter BW series the focus is on the optimal processing of plastic films for the downstream NIR sorting process. In addition to the constant volume flow and the uniform lumpiness, the optimized particle size is particularly important for NIR sorting. "With a grain size of DIN A4 to A3, we were able to achieve improved performance of the NIR systems for our customers," reports Stefan Scheiflinger-Ehrenwerth, head of product management at Lindner. “Every shredding process generates a certain proportion of fines in addition to the ideally chunky grain. With the gentle Jupiter BW set-up, we have managed to reduce the generation of fines by 50%, which is also confirmed by manufacturers of NIR sorting devices.” 

Polyamide for electromobility and industrial applications

The washing process is also an essential quality criterion for the high-quality regranulate production. Because plastics are increasingly being recovered from waste streams and, in this way, heavily soiled input materials are increasingly finding their way into plastics recycling, this is no easy task. “We know the problem only too well. But we also have the right solutions,” says Harold Hoffman, Managing Director of Lindner Washtech.

"We have ours patented pre-wash of the Rafter type adapted to the new requirements. The residence times can be increased by using a larger rotor, which of course has a positive effect on the degree of cleaning. In addition, we were able to sustainably increase the throughput, 3 t/h for films and 5 t/h for hard plastics, and we will be presenting this product innovation for the first time at the K trade fair,” adds Harald Hoffmann.

BASF establishes alliance against plastic waste with other companies

16.01.2019/30/XNUMX | Today, BASF co-founded a global alliance of around XNUMX companies to advance solutions that reduce and avoid the discharge of plastic waste into the environment, especially into the world's oceans. the Alliance against plastic waste in the environment (Alliance to End Plastic Waste, AEPW) has already committed $1 billion in funding with a goal of investing $1,5 billion over the next five years in various projects and collaborations.

New solutions for minimization and Management of plastic waste are to be developed and brought to market on an industrial scale. This also includes solutions for reusing plastics that have already been used in order to enable a circular economy.

Of central importance is the Identifying where the plastic waste comes from. Research from the environmental organization Ocean Conservancy shows that most of the plastic in the ocean comes from waste generated on land. Much of the plastic waste is carried by rivers and can be traced back to XNUMX major flows, mostly in Asia and Africa. Many of these rivers run through densely populated areas that lack proper waste collection and recycling infrastructure. This leads to an uncontrolled entry of waste into water bodies. The AEPW will start where the need is greatest.

Chemcycling as a new source of raw material from plastic waste

16.01.2019/XNUMX/XNUMX | Because the mechanical recycling of plastics is reaching its limits as the purity of the material decreases with each cycle, a BASF team developed a completely new approach to this challenge: The chemcycling project is a chemical recycling technology that replaces fossil resources for chemical production with recycled raw materials from plastic waste.
