Materials Green plastic

Materials Green plastic made of milk protein Lactips, based in Saint-Jean-Bonnefonds, France, is a young company focussed on the design, development and manufacture of an eco-friendly plastic raw material made of milk protein. The new, disruptive material, says the company, provides an answer to the problem of plastics pollution while meeting human needs. The plastic offers good gas barrier properties, is biosourced and biodegradable, making it suitable for a host of different applications. Lactips’ technology is based on scientific research conducted at the Jean Monnet University of Saint-Étienne, in France. In 2007, Frédéric Prochazka discovered a new process to transform casein (milk protein) into a thermoplastic raw material. The university subsequently patented the process, after which Marie-Hélène Gramatikoff has sought to commercialize it through the creation of a company called Lactips. Casein is one of the proteins that occur in milk. While there are several different types, all are widely available as a surplus of the milk industry. Casein is renewable, biodegradable and compostable. Lactips only uses milk that is unfit for human consumption for its non-food applications. The company designs, develops and manufactures its water soluble and biodegradable thermoplastic pellets using a twin-screw extrusion process. According to Lactips, the product has very considerable potential on the market. The company has opted to target the detergent market with its first product: water-soluble, biodegradable wrapping for dishwasher tabs and for single doses of chemicals. Lactips has developed a solution featuring a range of desirable of properties, including: Solubility: the plastic film dissolves in hot and cold water, leaving no sticky residues or clogged filters after washing. Detergent brands will therefore be able to use the ‘I prefer 30’ label. Biodegradability: Lactips’ product is completely biodegradable. There is no aquatic toxicity and it conforms to certification labels including Ecocert, EU Ecolabel and Ok Compost Home by TÜV Austria Belgium (formerly Vinçotte). Printability: the material is easily printable, offering excellent opportunity for enhancing brand recognition and for indicating instructions for use. Also, the film requires no treatment prior to printing. Gas barrier: the gas barrier properties are so high that the product can be used for food applications. Industrial compatibility: Lactips’ pellets have been adapted to all the supply chain processes in the plastic industry. The material can be easily and quickly processed without any new investment required, using existing standard machinery. Lactips’ material is disruptive as it opens up new markets, enables major actors in the detergent industry to innovate and to supply greener and better products, such as dishwashing and washing machines tablets, chlorine tablets for swimming pools etc. Moreover, this solution offers convenient, safe and ecological single-dose products to help agrochemical producers to overcome their challenges. Lactips also develops packaging solutions for food, medical and cosmetics markets. MT www.lactips.com 16 bioplastics MAGAZINE [02/18] Vol. 13

Thinkstep (headquartered in Leinfelden-Echterdingen, Germany) with support of the Institute for Bioplastics and Biocomposites (IfBB, Hannover, Germany) has developed an easy-to-use LCA tool to quantify the environmental performance of bioplastic products. The tool is based on thinkstep’s award-winning GaBi Envision Web platform, which allows access through a standard web browser to high quality LCA models in the GaBi database. The Bioplastics Tool covers the complete life-cycle of bio-plastics products and allows for a choice of different feedstocks, bioplastic materials (for example: PP, Bio-PE, PLA, Bio-PET, starch blends and polymers currently under development), standard and customized compounding and converting steps along with a wide selection of additives, transport along the supply chain and end-of-life options (incineration, land-fill, recycling, composting, where applicable). The tool also enables for a comparison with petro-chemical based plastics. The Bioplastics Tool calculates several environmental impact indicators such as the CO 2 footprint and displays the results in a customized report, which can directly be used for communication to customers. MT thinkstep and the IfBB will demonstrate the Bioplastics LCA Tool in a free webinar on 19 th April 2018 at 14:00 CEST.
