Jelu-Werk J. Ehrler GmbH & Co. KG, Rosenberg, Germany, offers the toy industry a material that combines the advantages of wood and plastic. Like plastic, Jeluplast can be molded three-dimensionally and offers wide scope for design, yet it also possesses the positive attributes of wood. The bioplastic thus attains greater strength and rigidity than plastic, which increases toy safety. In its warmth, feel and smell, the new material closely resembles wood.

In general, the low melt stability and lack of strain hardening of commercial polylactide (PLA) biopolymer render it unsuitable for making foams which, if they can be produced at all, are at best of low quality. However, even polylactide can be foamed if it is chemically modified in the right way.

Bioplastics are comparable to conventional materials, not only in terms of their mechanical properties. By adding simple mineral additives the fire protection of these materials is improved substantially. Different flame retardants were tested for a sandwich board from bio-based polyurethane with linen cover layers, and their performance has been proven.

Royal DSM is extending its range of high temperature resistant bio-based polymers with the introduction of a new family of high performance polyamide 4T materials, partially produced from renewable resources, called ForTii Eco. These new materials fit with the growing need of faster, thinner and more sustainable devices in the electronics industry.

Particle foams based on renewable cellulose derivatives could be an alternative to oil-based expanded polystyrene. In the context of a development project, researchers demonstrated that cellulose-based particle foams can be produced with varying densities using conventional processing equipment. In addition, these materials do not require halogen-containing flame retardants.

BASF SE, Ludwigshafen, Germany, is expanding its range of high performance foam products with the innovative, certified compostable particle foam ecovio EA. The product is predominantly biobased and, like all of the grades under the ecovio brand, it supports the biological cycle through its certified compostability.

ANA-U relies on injection molding technology from Wittmann to make molded parts from natural materials

Under the „Green Quality“ brand, the company ANA-U produces molded parts from natural ingredients consisting to 100 % of renewable materials. The parts are manufactured on an all-electric injection molding line from Wittmann.

ANA-U, established in 2007 by Ewald Ulrich, specializes in the development, production and global sale of cards, card printers and electronic components, as well as the development and design of lighting solutions for stationary retailers, shopfitters, museums and galleries. In addition to its facility in Gleisdorf, the company has another production plant in Austria and one in Shenzhen, China. In Japan, the company’s products are sold via a local agency.

For just under 3 years, ANA-U has been producing molded parts from natural substances under the „Green Quality“ brand. These consist to 100 % of plant-based renewable materials and are compostable just like wood. Typical products are event cards, voucher cards, wood-to-wood connecting parts and plastic-free housings. In this way, ANA-U has delivered, for example, 40,000 access passes for students of Karl Franzens University in Graz for the summer semester of 2022. For next year, the production of cards with imbedded electronics is planned as well.

The materials ANA-U is using for its Green Quality products grow again within one year. At present, the company keeps 100 tons of material in stock for its customers. The material mix is composed in-house according to each customer’s specific requirements. To provide a further benefit for the environment, Ewald Ulrich offers his customers to take back and recycle the Green Quality parts. The recycled material is then mixed with virgin material.

The Green Quality molded parts are manufactured on an all-electric machine of the EcoPower series from Wittmann Battenfeld with 1,600 kN clamping force. The EcoPower 160/750 is equipped with a fully integrated W918 robot, which removes the parts and deposits them on a conveyor belt. A Tempro basic C90 temperature controller and a Gravimax 14 gravimetric blender are also integrated in the machine’s Unilog B8 control system. The line is completed by a Coolmax C40 cooling device, an Aton plus 30–70 VS segmented wheel dryer, a Feedmax plus 206–40 material loader and a Dosimax MC Balance metering device.

In addition, the machine is fitted out with the HiQ Melt software package for monitoring the material quality, a feature of prime importance in processing plasticfree and recycled materials to enable fast response to viscosity fluctuations. A G-Max 12 granulator from Wittmann is used to recycle sprue, faulty parts and returned parts.

Ewald Ulrich and his son Sebastian, who is mainly responsible for the Green Quality product line, are very satisfied with the equipment from Wittmann. The most appreciated feature apart from the machine’s energy efficiency and low noise level is its high control accuracy. Ewald Ulrich comments: “Molded parts made of renewable raw materials require production machinery with high precision and extended options for parameter setting. This is provided in every respect by the EcoPower 160. In addition to the high quality of the machine, the perfect training programs and excellent customer support were decisive factors in reaching all our ambitious project goals.
