Designed by engineer Parinaz Pakniat, the PakVert system incorporates a core made entirely of recycled polyethylene terephthalate, identical to the plastic used in single-use drink containers. The resulting structural elements resist moisture, rot, pests, and mould, potentially doubling the lifespan of conventional homes. Beyond bolstering durability, homeowner Daniel Massé praised the structure for its rapid assembly and superior heat retention. This manufacturing method offers a scalable alternative that minimizes jobsite waste while dramatically reducing reliance on large work crews.

A two-bedroom home covering 1,078 sq ft in Saint-Rémi-d'Amherst, Quebec, has been built using structural panels made from the equivalent of about 200,000 recycled plastic bottles. The building shell was fully put together on-site in just three days. The project could offer a new way to build more affordable and sustainable homes across Canada. The building system, called PakVert, was developed by Quebec-based clean technology company PakVille. Founded by Canadian engineer and entrepreneur Parinaz Pakniat, the company designed prefabricated panels that combine the building structure, heat insulation, and outside finish into one lightweight part.
Recycled core technology
The centre of each PakVert panel is made from 100 per cent recycled polyethylene terephthalate (PET). This is the type of plastic commonly used in single-use drink bottles. According to technical details published by Construction Canada, the panels can be used for outside walls, floors, and roofs. They can replace several traditional building materials, including wood frames, fibreglass insulation, and outside wall panels.
PakVille says the panels' dense plastic material helps protect them from moisture, mould, rot, and pests. The company also estimates…
Media regulator Ofcom has secured a major legal victory affirming its authority under the Online Safety Act. Judges determined that the watchdog acted properly despite opposition from major social media platforms. The decision forces tech companies to comply with regulatory oversight and disclose information regarding their platforms.
The resolution halts an ongoing courtroom examination into the tech giant's legal accountability for youth mental health issues. Plaintiffs had argued that exposure to the company's platforms directly fostered debilitating conditions including severe depressive states and eating disorders. By resolving the matter mid-trial, the company avoids an immediate formal verdict on whether its software actively damages adolescent well-being.
The resolution arrives during a bellwether trial in Los Angeles state court that serves as a major test case for thousands of addiction lawsuits filed by individuals, municipalities, and school districts nationwide. Following agreements with both teenage plaintiffs, the ongoing legal battle now leaves Snap Inc. as the sole remaining defendant facing the jury.
