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.
It is a collection of contributions by different authors focusing on a proposal for indicators to monitor circular economy in Poland. A large part of the work consists in explaining that circular economy is more than just waste management.
The publication is in Polish, but abstracts of the different contributions are available in English at the end of the book (from page 203 onwards).
The EduZWaCE platform is one of the intellectual outputs of the Education for Zero Waste and Circular Economy project, funded by the Greek National Agency under Erasmus+.
The platform is a virtual learning and collaboration environment for all interested stakeholders, using an interactive and collaborative online structure:
Knowledge Hub: interactive resource centre gathering useful information for Vocational Education and Training teachers and professionals
The main objective of the INSIGHT project is to develop a new professional profile: theindustrial symbiosis facilitator, who helps transition towards the design of a common curriculum and learning approach.
The electrical and electronics industry has been contributing to Europe socially and economically for almost 100 years. However, its production, use and disposal are resource- intensive activities resulting in significant environmental and climate impacts.
This European Environmental Agency (EEA) briefing describes how increasing product lifetime and improving ‘circularity’ are essential steps towards reducing impacts from electronics.
Case studies of 4 different electronic product groups show there is potential for significant increases in their actual lifetime use. Extending the lifetime and delaying the obsolescence of electronics can significantly reduce impacts and contribute to meeting EU environment, climate and circularity objectives.
The brochure highlights Dutch circular frontrunners that make a change - just a fraction of the initiatives, organisations and technologies available. Only the most inspiring examples have been selected, with a potential to be upscaled and implemented in other parts of the world, hoping that they will also inspire and encourage others to collaborate and make a change.
The French company, Envie Autonomie, collects and renovates technical equipment, such as wheelchairs, used beds, walkers and other aids. In this way, they ensure a second life to important equipment.
VICAT produces materials for the construction sector (cement, concrete, aggregates) and believes that the act of building should no longer be disconnected from deconstruction. VICAT has therefore rethought its production systems to include circular economy loops focused on the recovery of local construction & demolition waste.
