Circularity challenges the current economic model towards a sustainable future
Circular processes contributing to circularity can be grouped into 4 categories, from the most impactful to the least:
1. Reduce by design: reducing the amount of material used, particularly raw material, should be applied as an overall guiding principle from the earliest stages of design of products and services
2. From a user-to-user perspective: Refuse, Reduce and Re-use
3. From a user-to-business intermediary perspective: Repair, Refurbish and Remanufacture
4. From business-to-business: Repurpose and Recycle.

Incompatible trends - Hazardous Chemical Usage in Building Products Poses Challenges for Functional Circular Construction
Abstract: Based on a review of 2012 and 2016 data in the Nordic chemical database, SPIN, this paper is an assessment of the usage of REACH’s Substances of Very High Concern (SVHC) and Denmark’s List over Undesirable Substances (LOUS) chemicals in the building industry in Denmark. The paper is a status update of the 2016 Danish Environmental Agency’s report of the usage of hazardous substances in sustainable buildings, based on 2012 data from SPIN. The analysis focuses on change in tonnage of usage of chemicals found in twelve different construction product categories in SPIN, crosschecked with substances from the SVHC and the LOUS lists. The usage of some hazardous substances in certain usage categories has reduced from 2012 to 2016.
There is an overall trend indicating an increase of undesirable chemical in construction articles and preparations, which poses serious challenges for a functioning circular built environment. Findings indicate which construction categories and which chemicals are of particular concern for the current construction market in Denmark. The results underscore the essential need for transparency in building product content, in order for design professionals and contractors to make decisions that support the future use of the material or building element.
Transitioning To A Circular Economy Through Chemical and Waste Management
The presence of hazardous chemicals in products makes the transformation to circularity more challenging. This report describes UNDP's interventions on Chemicals and Waste Management which aim to achieve circularity across different industries, inluding construction.
Toward a Circular Economy for the Electronics Sector in Latin America and the Caribbean (LAC): Overview, Actions and Recommendations
This report provides an overview of the current status and conditions of the Circular Economy in the electronics value chain in the Latin America and the Caribbean (LAC) region, identifies key areas of concern, provides appropriate recommendations, and proposes priority actions to improve circularity of the sector. The recommendations and roadmap focus on the individual life cycle stages of the electronics value chain, as well as on aspects that cut across the value chain. The transition towards a more circular electronics sector in Latin America and the Caribbean (LAC) would require a holistic and coordinated approach to progress toward a more circular electronics value chain in the CEE region.
