How-to source sustainable materials
Making sense of green tags and finding the right thing for the job.

 

Sustainable materials and products – masses of them out there, but how do we assess exactly how sustainable anything is? There are myriad schemes, labels and means of accreditation, great variation between and within countries, huge scope for monetising the sustainability supply chain and the larger the organisation the more obscure the details.

A few suggestions:

1 Seek out small producers

Like Foresso who make a timber terrazzo sheet – locally sourced, using 85% recycled material, inherently durable and can be ground down to start again at the end of its use. A business with clear sight over their whole operation, making all decisions based on environmental consideration resulting in clear sustainable credentials. More info on timber types, fabrication, use and disposal on The Wood Guide.

2 Look for the detail behind the claim

Dodds&Shute are dedicated to sourcing responsibly produced furniture, a mission backed by a serious supply chain audit, sustainability report and a very clear website with product ranked according to environmental performance. Extremely helpful partners in any project involving sourcing and specifying furniture.

3 Tap into shared information

Haworth Tompkins in collaboration with co-signatories of Architecture Declares have published an open-access sustainable materials database, a generous move that is really useful for smaller practices and non-designers, and makes absolute sense – we don't have time for competition. Check their regenerative design page for information, research and project examples.

 

4 Keep asking questions

The more we find out about the subject the more we can demand from and challenge suppliers. Looking at a particular flooring material that trumpets its sustainable credentials I could not find any info on ways of installing without using adhesive, therefore no easy way of removing, and no detail on re-use or recycling even if it could be lifted without damage. After much back and forth this company told me they are looking into installing with a tacifier, and in a take-back scheme. Im not saying my question will change anything, but a lot of questions might.

For non-producer information the Construction Materials Pyramid allows comparison of materials across a range of measures, the Parsons New Schools Healthy Materials Lab has a wealth of learning resources.

5 And finally look at the bigger picture

The Ellen Macarthur Foundation explains circular design in action, principles, how-to, business benefits and has useful toolkits on all aspects of consumer society.
