How Durable Are Biopolymers?

In Scheplast‘s own words, the company combines injection molding and sustainability. Real ambition or empty promise?

At their site in Schwendi/Hörenhausen,  Scheplast combines plastics processing and farming.

Compostable Bioplastics:  Italy Sets the Standard

Avient’s Maxxam BIO bio-based polyolefins utilize natural fillers such as cellulose fiber or recycled coffee grounds, which would otherwise go to waste.

New Maxxam BIO Bio-based polyolefins can be filled with up to 40 % bio-filler from used coffee grounds or cellulose fiber.

Giving Waste Coffee Grounds a Second Life

The flame-retardant requirements of E&E devices cannot be met with biopolymers. Research shows that this could soon be possible with bio-based flame retardants.

The addition of wood particles improved the flame resistance of the Bio-PA test specimens.

PLA’s elongation at break and impact strength stand in the way of its broader use. PLA copolymers look like a promising solution.

A view of the production of the PLA copolymer compounds: the proprietary process combines chemical synthesis of polymers and production of compounds in a single process.

With the processing of increasingly “green” plastics, Bausano, an Italian manufacturer of extrusion lines, is opening itself up to the circular economy.

Bausano tested a wide variety of material mixtures of more sustainable plastics on its extruders.

The K 2022 offered an immense range of innovations and application examples for – and with more – sustainable materials. Interestingly hereby was that bio-based versions were extremely popular.

Shoes made from waste gas: genetically modified bacteria produce ethanol from waste gas, which is then used to create plastic, e.g. for the Cloudprime shoes from On.

At K 2022, it was clearly shown that with suitable materials not only can CO2 emissions be reduced, but also advantages in component design achieved.

The Japanese chemical company Asahi Kasei showed its concept vehicle at K 2022. The domed roof in particular could lead to a few changes in future automobiles.

A trade show highlight of masterbatch manufacturer Lifocolor will be its biodegradable plant-based color concentrates. These are claimed to enable a closed-loop system for biodegradable plastics.

When it comes to long-term closed-loop recycling, it is not only the plastics that matter, but also the colorants employed. Lifocolor has developed masterbatches specifically for coloring recycled materials.

Calculating and Reducing the Carbon Footprint

Due to the aspect of sustainability, natural fibers are interesting as reinforcements for plastics. To keep their ecological footprint as low as possible, it is advisable to use fibers from regionally grown plants.

The “perennial cup plant” is cultivated in Germany for biogas production. The fibers of the plant can be extracted from the resulting fermentation residues and subsequently used for composites.

The plastics industry has a variety of materials and technologies available for significantly reducing the ecological footprint of products. There are very few applications for which it is not possible to replace at least a portion of the fossil material with recyclates or bioplastics. Various methods, standards and software tools are available to determine what savings this can achieve.
