Concepts to protect wood from factors like ultraviolet (UV) radiation, water and wood-decaying fungi with the help of fungi exist in different variants. The idea to treat wood with the help of linseed oil and the living fungus Aureobasidium pullulans originated in 1996 during an European project assessing sustainable protection systems (Sailer et al., 2010). At that time, wood impregnated with natural oils resulted surprisingly in an evenly dark colored surface. These color changes were usually associated with irregular discoloration and staining and were further investigated. It has been shown that the fungus Aureobasidium pullulans was growing on surfaces treated with linseed oil. The fact that Aureobasium pullulans reproducibly grows on water repellent linseed surfaces in many regions around the world makes it suitable for use in a wide range of applications. Research did show that Aureobasidium pullulans produces pigments and binders on its own. This contribution documents the investigation to, identify the possibilities of biological wood surface treatment with Aureobasidium. The combination of the hydrophobizing effect of linseed oil and the surface treatment with the so-called biofinish creates an aesthetically appealing dark living surface, which significantly prolongs the life of wood outdoors and reduces maintenance costs. Since the idea has been developed into an industrially applicable process (Xyhlo biofinish, 2018). Using this concept, building components e.g. façades can be protected with a biological and functional coating thereby contribution to lessen the environmental impact of buildings.

Recycling of plastics plays an important role to reach a climate neutral industry. To come to a sustainable circular use of materials, it is important that recycled plastics can be used for comparable (or ugraded) applications as their original use. QuinLyte innovated a material that can reach this goal. SmartAgain® is a material that is obtained by recycling of high-barrier multilayer films and which maintains its properties after mechanical recycling. It opens the door for many applications, of which the production of a scoliosis brace is a typical example from the medical field. Scoliosis is a sideways curvature of the spine and wearing an orthopedic brace is the common non-invasive treatment to reduce the likelihood of spinal fusion surgery later. The traditional way to make such brace is inaccurate, messy, time- and money-consuming. Because of its nearly unlimited design freedom, 3D FDM-printing is regarded as the ultimate sustainable technique for producing such brace. From a materials point of view, SmartAgain® has the good fit with the mechanical property requirements of scoliosis braces. However, its fast crystallization rate often plays against the FDM-printing process, for example can cause poor layer-layer adhesion. Only when this problem is solved, a reliable brace which is strong, tough, and light weight could be printed via FDM-printing. Zuyd University of Applied Science has, in close collaboration with Maastricht University, built thorough knowledge on tuning crystallization kinetics with the temperature development during printing, resulting in printed products with improved layer-layer adhesion. Because of this knowledge and experience on developing materials for 3D printing, QuinLyte contacted Zuyd to develop a strategy for printing a wearable scoliosis brace of SmartAgain®. In the future a range of other tailor-made products can be envisioned. Thus, the project is in line with the GoChem-themes: raw materials from recycling, 3D printing and upcycling.
Alcohol Use Disorder (AUD) involves uncontrollable drinking despite negative consequences, a challenge amplified in festivals. ARise is a project using Augmented Reality (AR) to prevent AUD by helping festival visitors refuse alcohol and other substances. Based on the first Augmented Reality Exposure Therapy (ARET) for clinical AUD treatment, ARise uses a smartphone app with AR glasses to project virtual humans that tempt visitors to drink alcohol. Users interact in a safe and personalized way with these virtual humans through phone, voice, and gesture interactions. The project gathers festival feedback on user experience, awareness, usability, and potential expansion to other substances.Societal issueHelping treatment of addiction and stimulate social inclusion.Benefit to societyMore people less patients: decrease health cost and increase in inclusion and social happiness.Collaborative partnersNovadic-Kentron, Thalamusa
Lupineschillen (lupine zaadhuid) zijn een reststroom van lupineverwerking. Lupineschillen vormen 25% van de totale biomassa van de lupineboon, terwijl sojaschillen slechts 5% van de totale biomassa van de sojaboon zijn. Er zijn onvoldoende rendabele toepassingen voor lupineschillen waardoor de rentabiliteit van de lupine supply chain achter blijft bij de veel competitievere soja supply chain. Lupineschillen zijn rijk aan de actieve stof lupeol waarvan recent farmaceutische en cosmetische anti-aging werkingen zijn vastgesteld, waaronder anti-tumor werking. Lupeol komt naast lupine ook in hoge concentraties voor in berkenbast. Berkenbast bevat bovendien een chemische voorloper van lupeol namelijk betuline. Recentelijk is er een chemische syntheseroute ontwikkeld voor lupeol op basis van betuline. Als deze syntheseroute kosteneffectief is, dan kan deze route de ontwikkeling van nieuwe toepassingen van lupineschillen blokkeren.Het doel van deze studie is het opstellen van een circulair ontwerp voor lupeol extractie uit twee reststromen met behulp van superkritische CO2 extractie en de kosteneffectiviteit van deze circulaire ontwerpen met elkaar vergelijken voor het selecteren van het meest optimale proces voor lupeol extractie en/of synthese. Bovendien worden mogelijke cosmetische anti-aging effecten van lupeol getest.Met behulp van superkritische CO2 extractie is het mogelijk om lupeol kosteneffectief uit lupineschillen te extraheren. De alternatieve syntheseroute van lupeol uit betuline zoals deze in de wetenschappelijke literatuur was gepubliceerd bleek niet reproduceerbaar te zijn. Patentliteratuur leverde een reproduceerbare syntheseroute. Vergelijking van de twee routes was nog niet mogelijk vanwege de lage omzetting efficiënties van de syntheseroute. Daarnaast zijn er mogelijke intellectuele eigendom issues. De effectiviteit van lupeol is in vitro en in vivo getest. Hieruit bleek dat lupeol in tegenstelling tot de literatuur minimale effecten had op huidcellen. De huidelasticiteit bij proefpersonen nam enigszins toe na gebruik van een cosmetische formulering met lupeol.Uit onze studie is gebleken dat we kosteneffectief lupeol kunnen extraheren met behulp van superkritische CO2, dat de alternatieve routes voor lupeol synthese nog niet mogelijk zijn en dat we enige anti-aging effecten van lupeol hebben kunnen vinden bij toepassing in cosmetische producten.
