Worth bookmarking for anyone specifying acoustics who wants to keep synthetic binders and plastic content out of the spec — the tech specs and customer cases give you what you need to evaluate it properly.

spared.eco

Spared is a UK sustainable design studio that turns client-supplied waste into bespoke materials, furniture and artworks — the Aviva reception desk and Fortnum & Mason oyster-shell fixtures are proof it works at a commercial scale. Worth bookmarking as a specialist partner for circular-material briefs, even if the site itself is a portfolio rather than a deep resource.
