Sparxell cellulose-based biodegradable pigments

Sparxell produce non-toxic and biodegradable pigments from cellulose. Their technology exploits the highly reflective nature of plant-based cellulose. The colour comes from reflected light, so called structural colour, does not fade and can be used in the same contexts as conventional pigments, glitters, and sequins. The company does not use mica, titania or dye, ensuring their pigments have the least impact possible on the environment. Image Sparxell.

Recycled and bio-based Surlyn ionomer plastic for cosmetics packaging

Two new Surlyn ionomer resins developed by Dow offer carbon savings compared to virgin material. Surlyn REN ionomers are produced using bio-waste such as cooking oil. This process utilises waste residues or by-products from alternative product processes from other industries meaning the raw feedstock materials will not consume extra land resources or compete with the food chain. Surlyn CIR ionomers are created through chemical recycling technologies, breaking down mixed waste plastics into their basic chemical elements, giving plastic waste a second life. This produces a raw material that is equivalent to those made from virgin fossil feedstock. Image Dow.

VTT pilot plant to process captured CO2 into raw materials for plastics

VTT, LUT University, and companies (including Borealis) have opened a pilot plant in Finland to process captured CO2 into compounds that can replace fossil raw materials in the production of polypropylene (bio-PP) and polyethylene (bio-PE). At this stage, they are produced at VTT Bioruukki from flue gas carbon dioxide. In the future, the technology can be brought into production wherever bio-based carbon dioxide is produced, such as in forest industry or waste incineration plants.

Made of Air carbon-negative additive for plastics

Made of Air convert biomass waste streams (such as forestry offcuts and secondary agricultural materials), which have photosynthesised CO2, into a form of biochar through controlled pyrolysis. Burning materials without oxygen means the carbon cannot form CO2 and instead forms biochar. Using their technology the biochar is converted into a functional carbon-rich filler for plastic biocomposites. Biochar has been produced for centuries and is increasingly being used as a fertiliser as well as a way of sequestering carbon in the soil, because the carbon is locked in and it remains stable for hundreds of years.

UBQ thermoplastic additive made from household waste

The feedstock for UBQ is household waste, which is largely comprised of organic materials – everything from food residues and mixed plastics to cardboard, paper, and even dirty diapers, that would have otherwise been sent to landfill or incineration. Metals and minerals, which have high recyclability, are removed and sent over to traditional recycling streams. UBQ’s waste conversion technology breaks down the organic matter into its basic particulate constructs—lignin, cellulose, fibres, and sugars—and then reassembles them into a matrix. Residual plastics present in the waste stream melt and get mixed into the matrix to create a homogeneous and consistent composite thermoplastic material. Image UBQ.
