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.

Over half a million tonnes of discarded electronic appliances are improperly processed in Nigeria every year, threatening the country's environment and the health of approximately 100,000 informal workers in the recycling industry.
With support from the Global Environment Facility (GEF), the Government of Nigeria has joined forces with the United Nations Environment Programme (UNEP) and partners to turn the tide on e-waste under the “Circular Economy Approaches for the Electronics Sector in Nigeria” project. Led by UNEP and supported by the National Environmental Standards and Regulations Enforcement Agency of Nigeria (NESREA), the $15-million initiative brought together players from the Government, the private sector, and civil society to design and operationalise a financially self-sustaining circular economy (CE) for electronics in Nigeria.
The project aims to stimulate a CE pilot through an Extended Producer Responsibility (EPR) scheme that serves as a model for countries facing similar challenges. EPR is an integrated waste management approach that extends the responsibility of manufacturers to the entire lifecycle of their product, particularly to the end-of-life treatment. By applying this approach, the producers will be obliged to commission for collecting, pre-treating and recycling their originated e-waste. 
The project creates synergies among pre-existing elements of an EPR system in Nigeria to establish a sustainable management system and financing mechanism for EPR implementation. Establishing and enforcing a sustainable approach in Nigeria with supporting regulations and legally binding requirements is expected to recover and re-introduce usable materials into the value chain, dispose of hazardous e-waste streams in an environmentally sound manner, and create safe employment for Nigerian e-waste workers.
