BIOPLASTICS CONFERENCE 12.10.2020 – invited experts spoke about the respective bioplastics At the start of the project, invited experts, entrepreneurs and scientists presented the different bioplastics with which we intended to work on during the semester. Subsequent to this online conference, the students chose a bioplastic for which they were to develop circulating applications. Protein […]


CIRCULARITY CONFERENCE 20.10.2020 – invited experts spoke about circularity possibilities and hurdles During a one-day digital conference we discussed the complex aspects of circulating materials, especially bioplastics, with invited experts from different fields: Manuel Bickel, Wuppertal InstituteManuel Bickel from the sustainable consumption and production division highlighted the complexity of the sustainability assessment of plastics. For […]

What does mechanical recycling of plastics mean? > Principles, comparisons, advantages and disadvantages, research and the future What does chemical recycling of plastics mean? > Principles, comparisons, advantages and disadvantages, research and the future What are the […]


IDEATION WORKSHOP 28.10.2020 – the master students carried out an ideation workshop During the third week of the semester, the master students prepared an ideation workshop for the project. The basic goal of the workshop was to develop a variety of ideas for concrete products with concrete cycles for the different bioplastics together with all […]


BACTERIAL CELLULOSE profile  by Stefanie Putsch, Dean Weigand & Elena Bangel Description of the material: Cellulose is a polymer made from the monomer cellobiose. It is the main component of plant cell membranes and is the most abundant biomolecule. The linkage of the monomers takes place through a condensation reaction in which two hydroxyl groups (-OH) form […]


PROTEIN-BASED BIOPLASTICS profile  by Charlotte Bolinski, Amon Zänker & Sophia Reißenweber Description of the material:Proteins consist of amino acids and are built up and broken down by enzymes. Depending on the protein source, they differ greatly in their composition. Proteases are enzymes that cut up other proteins. Through  cross-linking of amino acids by a certain enzyme, […]

PLA profile

PLA profile  by Caterina Plenzick, Anselm Wohlfahrt, Rafael Vinz & Lukas Keller Raw materials – basic building blocks/ starting materialsPLA is a biodegradable, bio-based, thermoplastic polyester. Through the biotechnological fermentation of sugar, lactic acid is produced in bioreactors with the help of bacteria from the Lactobacillus family, which is then polymerised. The starting materials for PLA are […]

CHITOSAN profile

CHITOSAN profile  by Max Greiner, Lara Herrmann & Sophie Kikowatz Description of the materialChitosan is a substance obtained by deacetylation of chitin (the second most abundant natural biopolymer after cellulose). Natural occurrences of chitin are shellfish, exoskeletons of insects and fungi. The shells or insect carapaces are available in large quantities, e.g. in the production […]
