Wallenius Water Innovation is a Swedish clean-tech company that works with UV light to prevent bacterial growth in metalworking fluids. The non-toxic solution secures long-lasting process fluids without using hazardous biocides. In this way, fluids can more easily be reused in the installation rather than be disposed.
PU foam pressurised containers are used to fill gaps and to insulate and install window and door frames so as to make buildings airtight. OCF (one-component foam) producers have invested in a recycling company which recycles the metals in the packaging material, the reactive residual polyurethane prepolymer and the propellant.
Saccharides are a valuable and readily available source of renewable carbon. There are unique opportunities to produce renewable intermediate chemicals and polymers from regionally available agricultural products and imported feedstock in the period up to 2050.
Industry in the Chemport region (Northern Netherlands) has several options to further reduce CO2 emissions, including recycling or circular chemistry and shifting towards bio-based feedstock, acting as a catalyzer for other industries.
Important focus areas of the saccharide roadmap are:
developing technologies/markets
strengthening/expanding feedstock production
developing incentives/regulations
further developing an integrated approach, cooperating and improving the knowledge base.
ZERO BRINE proposes a circular economy approach to reduce the negative impacts of brine from process industries and create economic value from the reuse of its constituents, such as sodium chloride, magnesium, calcium, sulphates, sodium bicarbonate, heat and fresh water.
Unveiling a Recycling-Sourced Mineral-Biocellulose Fibre Composite for Use in Combustion-Generated NOx Mitigation Forming Plant Nutrient: Meeting Sustainability Development Goals in the Circular Economy
NOx (nitrogen oxides) are emitted during combustion in air at high temperatures and/or pressure; if they exceed recommended levels, this has a negative impact on the population. The authors found that when moist, limestone (CaCO3) readily sorbs NO2 to form calcium nitrate, which provides the basis for developing a surface flow filter. The substrate was made from “over-recycled” cellulose fibres such as newsprint, magazines and packaging fibres which are too weak for further recycling. The substrate was coated with fine-ground calcium carbonate and micro-nano-fibrillated cellulose, which was used as a binder and essential humectant to prevent a stagnant air layer forming. Pre-oxidation countered the action of denitrification bacteria colonising the cellulose substrate.
A solvent-free adhesive that is suitable for recycling and also for bonding of recycled plastic films has been developed by Henkel to be used for multilayer packaging.
