The LBC has a list of toxins that builders must avoid. A long one. And it took building planners an extra year just to scour the “red list” and figure out how to source over 1,000 everyday building materials without choosing ones with known toxins. From paint to plywood, almost every material in the building required a rethink.
As part of the material procurement process, materials needed local sourcing, not more than 300 miles away, if possible. It took creativity and, in some cases, ingenuity on the part of local vendors to recreate products using natural elements, whether a window sealant or a wood glue. In some cases, those new, natural processes proved more cost-effective for the company and became a new way of doing business, such as Portland’s Prosoco, which completely reworked a formula to eliminate toxic phthalates from its air-tight liquid building wrap.
