A case study as part of the European Commission's Green Public Procurement resources.  This example from Denmark shows how by using an overarching, centralised procurement strategy across more than 60 municipalities, the Danish government were able to address sustainability hotspots from wooden furniture, by bulk procurement of products that met ambitious sustainability criteria.

The bulk sourcing enabled cost savings, and criteria set ensured that furniture did not contain chemicals of concern identified by both Danish restricted substance lists and the REACH list of substances of very high concern (SVHC).  Products were required to meet higher standards of chemical safety, with dismantling criteria also set to improve circularity.

In recent years the majority of glues used in wood composite boards have been urea-formaldehyde (UF) and phenol-formaldehyde (PF) resins.  However, these products may cause human health issues due to off-gassing of formaldehyde, which is recognised by the World Health Organisation as a potential human carcinogen, which can also cause irritation of the eyes, nose, lungs and throat.

However, development of no-added formaldehyde (NAF) glues and resins is a growing area, which not only provide a safer indoor environment, but also can reduce the use of fossil-based feedstocks, and are biodegradable.  This case study looks at how NAF adhesives based on abundant soybean feedstocks, taking inspiration from processes in nature can address this chemical hotspot, and how the product was intially researched by Dr. Kaichang Li of Oregon State university, and came to market through collaborations with Columbia Forest Products and Hercules.  Soy-based adhesives can now demonstrate cost-competitiveness with UF adhesives, and are being widely procured for buildings seeking to achieve complaince with air quality regulations and higher building rating scores.
