The Marketplace, launched by NGO ChemSec on 17 May, hosts marketing materials from suppliers and requests for products, as well as guidance and case studies on substitution. It makes it easier for businesses to find less problematic alternatives to toxic chemicals. Both the ChemSec and other initiatives had hitherto focused on informing the industry of what not to use, as described in its ‘SIN list’, rather than suggesting suitable substitutes. The Marketplace should help improve the visibility of alternatives.
