Fraunhofer IWKS at K 2019: From Waste to Bio-degradable Food Packaging

The Fraunhofer Research Institution for Materials Recycling and Resource Strategies IWKS shows applications for a new polymer raw material made from food residues, which is not only bio-based but also biodegradable

Invitation to press conference on October 16, 2019, at 03:30 pm at K 2019 in Düsseldorf

Plastics are versatile materials - hardly any consumer product can do without this durable material. Especially for food packaging, plastic is able to guarantee hygiene requirements, long shelf life and easy availability of products. However, many high-performance plastic packaging products also contribute to increased waste generation and environmental pollution. Thus, the individual polymers cannot be economically recovered from multilayer packaging films for the production of new packaging films. BIodegradable bioplastics as a sustainable alternative have been on the market for several decades. However, a higher price and properties that still lag behind those of conventional plastics have so far prevented a broad application.

Fraunhofer IWKS has taken up this challenge and offers a new polymer raw material that increases the protective effect of plastic packaging without impairing its recycling or compost properties. It can be combined with both conventional and compostable packaging materials. Instead of using crude oil or biobased raw materials from corn or sugar cane, the researchers obtain their raw materials from large by-product streams in the food industry. In concrete terms, apple pomace is extracted into a hemicellulose product that is suitable for a wide variety of applications thanks to its branched polymer structures: from coatings that screen oxygen and water vapor, for films, trays and bottles made of plastics and natural waxes, to coating and paint systems as well as paper additives or cosmetic articles in which the polymer product can be used to increase tensile strength or adjust flowability and stabilize dispersions and emulsions. The advantage: The raw material is bio-based and biodegradable, does not compete with the food industry, is available in sufficient quantities and can be purchased as a by-product at low cost. The fact that the branched polymer structures can be chemically modified economically and in a variety of ways is fundamental for their application in various material systems.

Invitation to press conference - Project conclusion HyperBioCoat
As part of the EU-funded HyperBioCoat project, the raw material was successfully tested on demonstrators for food and cosmetic packaging. Find out more about the project and the use of hemicellulose as a sustainable polymer raw material and visit our press conference:

Not only replacing critical raw materials, but also recovering them
At K 2019, Fraunhofer IWKS will not only be demonstrating possibilities for substituting raw materials and valuable resources with sustainable alternatives, but also for recovering them. One example is electronic scrap. To date, the plastic fractions have not been or only thermally been recycled as secondary material, as they are difficult to separate efficiently and with a single grade. At Fraunhofer IWKS, the scientists are using electrohydraulic fragmentation and sensor-based sorting, whereby both metal and plastic fractions can be separated from mobile phones for example. This way, high-quality plastics can be recycled.

About us

Company portrait

Fraunhofer IWKS stands for the responsible use of resources.  Recovering recyclable materials from a product cycle and reintroducing them into a new cycle. This is the goal of Fraunhofer IWKS' research. Together with industrial partners, Fraunhofer IWKS develops efficient processes and technologies for the responsible use of the earth's resources. At the K trade fair, Fraunhofer IWKS will present its research work with a special focus on biogenic raw materials and innovative separation, sorting and recycling technologies.

The increasing use of bio-based raw materials in various sectors in the industry provides access to prominent growth markets. The utilisation of these materials is no longer limited to an energetic use and comprises bio composite materials, cellulose based polymers including nano-cellulose and bio refineries of the 3rd generation. The sources for bio based raw materials are vegetable waste streams from the food industry and agriculture. Key for a successful use is the isolation, reprocessing of and a quality management for the relevant raw materials. At Fraunhofer IWKS, the scientists are conducting research and developing biobased additives and binders, e.g. from residues of the food industry.

In the field of mechanical process engineering for the processing of primary and secondary raw materials, a large number of plants and equipment is available which can be used within the scope of service and research contracts. The focus of the work is the application and further development of innovative and flexible concepts for the preparation of materials and material flows with complex structures and compositions. In addition to innovative separation and shredding processes, the Fraunhofer IWKS also uses an automated, modular sorting system, which is used among others for electric waste, plastics or other materials.
