“Bio-based Material of the Year 2018”

Innovation award goes to Arctic Biomaterials

Materials - Wednesday, 27 June 2018

The Innovation Award “Bio-based Material of the Year 2018” was awarded to three innovative bio-based materials. The competition focused on new developments in the bio-based economy, which have a market launch in 2018. The winners were elected by the participants of the recent “International Conference on Bio-based Materials” in Cologne (Germany), organised by nova-Institute. 205 participants, mainly from the industry and representing 22 countries, met in Cologne on May 15 and 16 to discuss the latest developments in the sector. 21 companies presented their products and services at the exhibition.

 

Number 1 - Degradable PLA reinforced with glass fibre

ArcBioxTM BGF30-B1 is a polylactic acid (PLA) that is reinforced using LFT (long fibre) technology with a special degradable glass fibres. This innovation makes it possible that bio-based plastics can be used in technically demanding durable applications and still have the option of biodegradation at the end of life. The reinforcement is a glass fibre developed by Arctic Biomaterials and can also be used for several other bio-based polymers. This composite material reduces the carbon footprint and use of non-renewable energy of a composite product drastically compared to fossil-based reinforced plastics. This reinforced PLA is compostable and certified by the seedling mark from DIN Certco.

 

Number 2 - Cashew nutshell residual-based blocking agent

NX-2026 is an ultra-high purity 3-pentadeca-dienyl-phenol recently developed by Cardolite through advanced proprietary process technology. 3-pentadeca-dienyl-phenol is the main component distilled from cashew nutshell liquid, a renewable and non-edible resin extracted from the honeycomb structure of the cashew nut. NX-2026 has been successfully introduced to the coating and adhesive market as a non-toxic isocyanate (NCO) blocking agent that is a suitable replacement for petrochemical phenols. NCO systems blocked with NX-2026 provide lower viscosity and deblocking temperature than equivalent systems blocked with phenols. Moreover, NX-2026 blocked NCO prepolymers can be used in 2K epoxy systems to improve bond and T-peel strengths while maintaining good cure properties.

 

Number 3 - Bio-based and biodegradable nets for green beans

A packaging material which is more than 80% bio-based and more sustainable than conventional polyethylene nets but has similar linear weight and mechanical properties. The innovative product developed by Aimplas Instituto Tecnológico del Plástico (Spain) is a biodegradable net suitable for green beans packaging. A compound has been developed through reactive extrusion and the combination of different biodegradable materials and additives. Chemical modification was made by grafting low molecular weight units, such as oleic alcohol, obtained by the fermentation of sugars extracted from vegetable waste (watermelon).

 

Special award for the best bio-based concept

The Warka Water project provides an alternative water source (The Warka Water Tower) for rural populations that faces challenges in accessing drinkable water. The bio-based tower is 11 m tall and weighs only 80 kg. The triangulated frame structure, made with bamboo, is optimized for lightness and strength and offers both stability and robustness. Inside the bamboo structure hangs plastic mesh that collects droplets of water from high humidity in the air (fog) and the collector for dew and rainwater.
