Construction plastics are a major source of plastic waste in the province, and they urgently need to be measured, tracked and upcycled, says a B.C. organization that promotes sustainable built environments. Canada’s Federal Plastics Registry is expanding in 2026 to include construction plastics, but industry efforts are already underway to gather data and pilot new ways of reducing and reusing them, said Vancouver-based Light House. Construction plastics include packaging; wrapping for lumber and mass timber products; film that goes around pallets.  A new study by Light House is “the first national effort” to gather and compile data about construction plastics in Canada, in order to lay a foundation for tackling the problem. …The case studies include the new PNE Amphitheatre, a bridge, a community centre and library, a school and a multi-unit residential building—“projects that really represent the diverse range of construction that happens,” Yaron said.
