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

Kunststoff-Recycling

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.

What Is Happening in Chemical Recycling?

The development of a functioning and efficient recycling economy is strongly dependent on the quality of the recycled plastics. New plant and process technology is promoting this development.

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 CO<sub>2</sub> 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.

Twin-screw extruders enable even contaminated post-consumer polystyrene to be depolymerized continuously and efficiently. This opens up a promising recycling route in terms of industrial implementation via renewed polymer synthesis to produce plastic granules with a quality approaching that of virgin material.

The central issue in all polyurethane applications is the conversion from the past linear economy into a circular economy, and the use of sustainable raw materials in manufacturing. To do so, manufacturers are taking measures such as using bio-based raw materials, chemical recycling, and CO2 as a synthesis component. Digitalization, electromobility, autonomous driving and the construction industry are also driving PU development.

Plastics processors have a wide range of colors at their disposal to color their products. Choosing the right color can ultimately be the key to success. But colors are just as subject to trends as materials and designs. Kunststoffe asked manufacturers of pigments, masterbatches, and colorants which colors would be particularly popular in the coming year.

What Will Be the Color of 2021?

Plastic waste in the sea has been shaping the negative image of the industry for several years. Various initiatives and mergers of companies have therefore launched projects to tackle this Ocean-bound Plastics (OBP). Components made of OBP could become a symbol for a sustainable use of plastics.
