Sustainable development is the focus of the Israeli company Tosaf’s trade show presence. The company presents functional, color and combined masterbatches for processing by extrusion and injection molding. These will include color masterbatches for recyclates with a special focus on post-consumer plastics as well as biodegradable masterbatches.

All Things Sustainable

The circular economy, electromobility and the continuing corona pandemic are influencing color selection for plastics. Kunststoffe asked colorant manufacturers about the resulting color trends. We also wanted to know what effects the increased use of recyclates is having and the extent to which manufacturers are affected by the present supply bottlenecks.

Those in charge at Engel are convinced: Digitalization is not just a technical issue, it is also a mental hurdle, and sustainability is a lot more than hype. At the live e-symposium 2021 from June 22nd to 24th, 2021, the supplier of injection molding systems bridged the gap between the two megatrends of our time. And showed how the one can help jump-start the other.

Digitalization Is the Key

The plastics industry is currently struggling to raise its profile with positive headlines. The Kunststoffe editorial team discussed the present status of the plastics industry with representatives from industry, universities, and trade associations. Besides topics such as recycling and sustainability, the main focus was on recruiting young talent and the image issue.

“Plastics Experts are the Solution –  Not the Problem!”

Polymaker will offer the Polymaker PC-r 3D printing filament made from recycled polycarbonate (PC). The PC for the filaments comes from materials supplier Covestro and consists of a combination of recycled plastic waste and virgin material.

With the microcellular technology, in which a foam structure is created in the polymer by environmentally friendly gases such as CO2 and N2, it is possible to reduce the packaging weight.

Less Plastic for More Sustainable Packaging

Biodegradable plastics are special polymers designed to biodegrade after use. But conventional granulation equipment cannot handle biodegradable production rejects adequately. The new Bio-Gran technology by CMG Granulators was designed to accomplish this objective.

Recycling Made Possible with Bio-Gran

Recyclates usually show altered properties compared to virgin plastics due to initial processing and influences during the product’s life. This often leads to problems during processing. Especially in melt-expanding processes such as injection stretch blow molding, blow molding, film blow molding or thermoforming a fast incoming goods inspection method for recyclates is important. The Institut für Kunststofftechnik (IKT) at the University of Stuttgart, Germany, has developed a new test method for this purpose.

When processing post-consumer PET bottle flakes for reuse in bottles, the purity requirement for the material combined with the high degree of contamination of the bottle flakes make high demands on melt filtration.

Advances in Plastics Recycling Processes Towards the Creation of a Circular Economy

Climate change and the transport revolution are demanding smart fiber-reinforced composite solutions. In sectors such as the marine industry, infrastructure, and rail vehicle construction, many different fire protection concepts are competing. The composites industry is paying increased attention to recycling.

Composites Are Trendsetters in Lightweight Design

Bio-based plastics can lock away vast quantities of CO2 in durable, recyclable applications and make a real contribution to climate protection. All that is needed for this is the right product design and a functioning circular economy. By focusing more on this approach, the plastics sector has the chance to evolve into a key industry of a green economy.
