Up until now, recycling of waste streams based on mixed plastics has often proved to be unfeasible from a performance and overall cost-benefit perspective. DuPont brings a new solution to this important challenge, with its new series of Entira EP copolymers. These high performance compatibilizers, based on ethylene copolymers, are able to boost the performance of recycled polyolefins to a similar level as virgin resins.

That polyurethane can make a valuable contribution to the current trends of resource efficiency, lightweight design, sustainability and recycling that are prevalent in every industrial sector is demonstrated by the PU industry in the form of new solutions for increasingly demanding economical and ecological challenges. In this way, PU as a reactive material is confirming its great potential to be a long-term alternative to existing materials, and this not only because of its versatility.

Upcycling: From Old to New  

The Procter & Gamble Company announced that its shampoo brand Head & Shoulders (H&S) will produce the world’s first recyclable shampoo bottle made from up to 25% recycled beach plastic. In partnership with recycling experts TerraCycle and Suez, this innovation will come to France this summer as a limited-edition H&S bottle available to consumers in Carrefour, one of the world’s leading retailers.

Post-consumer material, especially household packaging waste, is considered to be plastic which is difficult to recycle due to impurities and the fluctuating degree of contamination. These contaminants often cause an unpleasant odour in the recyclates which severely limits the scope of use with the end products. The Erema Group introduces the ReFresher which eliminates odors caused by migrated substances, i.e. residues left on the plastic materials. These include, for example, food contamination, cleaner/detergent residues and cosmetics.

Mineral fillers are widely used in the automotive industry to enhance the performance of polymer grades. A recycling concept has now been developed, in which natural fiber-reinforced polymers are pyrolized to produce pyrolysis char as an alternative filler for thermoplastics.

For recycling to function successfully, the EU has defined five fields of action, among them: plastics. The reuse of plastics as often as possible is a common goal of politics, special interest groups, and business. But the opinions on specific measures are divided, as became clear at the conference of Petcore Europe, an association of the PET industry.

The Carrot or the Stick? 

During extrusion, recycled pellets from post-consumer material principally lose high volatile odor substances. To make them suitable for an even wider range of end products a downstream thermal-physical cleaning process removes the high molecular odor substances.

Rarely does a single material meet all automotive engineering requirements. Yet hybrid materials cannot be disassembled manually with reasonable effort, so that production waste is only being used thermally to date. Sensor-assisted plastic sorting however promises good yields and has economic potential.

There are various approaches to tackling the global problem of plastic waste in the sea. While producers are mainly focused on preventing dumping, processors can get involved in recycling the wastes into new products. The value chain begins with collection at sea. Support for this is provided by the public-private foundation Waste Free Oceans, an initiative of the European plastics recycling and converter sector. … Volker Scheel, CEO of K. D.

The new German law on materials and the emerging EU circular economy law are not the only things behind changes in the branch: the plastics industry is becoming increasingly involved in the reuse of its materials as raw material.

The Recycling Chain Is Linking Up 

Flexible films are extremely light-weight, easy to decorate, and are, therefore, often the first choice for packaging material. However, recycling them is considered a problem – they often end up in being incinerated for energy production, or even in the garbage dump. A consortium of industrial companies wants to change that. 

An Initiative Aims to Prevent Multi-Layer Packaging from Becoming Waste  

Focusing on Flexibles 

Despite fluctuations in the quality of input materials, end products are expected to meet high quality standards, especially in the food sector. The wide range of products available on the fast-paced global PET packaging market calls for a high degree of versatility on the part of plastics converters. For this reason, it is necessary to have lines which have a short process chain capable of producing good quality and which can respond rapidly to different requirements.

Interseroh Dienstleistungs GmbH, Cologne, Germany, has developed a new formula of its recycling plastic Procyclen. Thanks to the use of special additives from ExxonMobil Chemical, this recompound made from post-consumer waste receives substantially increased impact resistance, which leads to even greater resilience, especially at room temperature.

Sesotec Sorting Systems Help Ensure High Quality in PET Flake Production 

With the rise in consumption of raw materials, plastic processors are facing higher political and social demands to use a greater proportion of recycled materials. Companies such as MultiPet GmbH, a recycling company which processes used PET materials into flakes, make this transition possible. Along with their sister company Multiport, which specialises in making HDPE compounds from packaging waste, they are considered important suppliers of secondary raw materials for the plastics processing industry. 

How does the PET recycling process work? 

MultiPet receives pressed bales of pre-sorted PET waste. After the bales are broken up, plastics are first checked for impurities, then ground into flakes and intensively washed. 

The FLAKE PURIFIER+ multi-sensor sorting systems from Sesotec come into play directly after the ground material has undergone a two-stage density separation process involving two rounds of hot washing. At this stage, the sorting systems separate discoloured materials, foreign plastics and metals from the flakes. 

Sesotec FLAKE PURIFIER+ units are designed especially for use in plastic flake processing and are characterized above all by ease of operation and heightened throughput capacities. 

At MultiPet, the FLAKE PURIFIER+ systems are equipped with multiple sensors for colour and material recognition. This enables MultiPet to produce PET flakes in batches of different colours and qualities for use as raw materials in the plastics processing industry. By using recyclates produced by MultiPet, plastic processors are reducing their CO2 footprint, contributing to climate protection and conserving resources. 

“Sesotec’s processing technology enables us to keep the loss of good material to a minimum”, says Herbert Snell, Managing Director of MultiPet GmbH. “This makes our sorting processes even more efficient.“ Sesotec‘s scope of delivery was complemented by a turn-key material handling setup which included steel work platforms and material conveyance systems, simplifying integration into the overall system.
