The Healthy Home Guides provide advice and guidance on hazardous chemicals to avoid in different types of building materials. The guides include key product features to look out for and recommended alternatives that are healthier and more sustainable.

This handbook is aimed at helping the American architecture and construction sectors select healthier and more sustainable  materials for their projects. The handbook outlines guidelines for evaluating and selecting materials based on factors such as lifecycle assessment, material transparency, and health and wellness impacts. It also suggests useful tools and provides examples from case studies.

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.

Safer Consumer Products (SCP) has compiled a list of alternatives to PFASs in carpets and rugs to assist manufacturers looking for substitutes. The alternatives have been grouped into two categories: non-chemical and chemical alternatives. Products and manufacturers are listed but they are not endorsed by SCP and the safety of the alternatives has not been assessed.

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.

PFAS chemicals are found in many product types, including in adhesives, carpets and paints.  The PFAS Guide from ChemSec provides a tool to determine where PFAS may be found, and guidance on regulations, substitution, and engaging the supply chain.

OECD assists countries in developing and harmonising methods for assessing risk to human health and the environment, including methodologies for hazard and exposure assessment.  A range of resources on chemical assessment are available, including a Manual for the assessment of chemicals, Guidance on grouping of chemicals and a Risk Assessment Toolkit.

Legislation is not in place in every country to manage chemicals of concern.  The OECD Compare your Country Interactive mapping tool shows where legislation is in place and in development to manage industrial and consumer chemicals. 

The tool also includes a series of country profiles, providing details of legislation, the year of adoption and the approximate number of industrial chemicals assessed per year.
