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.
The Alliance for Flame Retardant Free Furniture welcomes the new Circular Economy Action Plan and calls on EU institutions to address the unnecessary use of chemicals preventing circularity and the achievement of climate goals, such as toxic flame retardants in furniture, which endanger people’s and firefighters’ health as they migrate out of products and can lead to increased fire toxicity.
The use of such retardants is a historical, hazardous and ineffective practice which is not proven to reduce the number of fires. It is at odds with circularity objectives and their presence in furniture runs counter to the ambition to introduce and increase circularity.
Ensuring fire safety is a must, but it needs to be done in ways that are not hazardous.
