Converting Landfill into Lumber
GreenWell Plastics is a plastic lumber manufacturer in Ontario, Canada that converts landfill-destined and recycled plastics into new products and resources.
What We Do
Landfill Diversion
Our focus since inception has been to displace as much plastic waste from landfill as possible, and over 2 million pounds later, we know this is only the beginning.
Plastic Lumber
At the core of our business, we have spent years developing our formula to ensure our HDPE lumber is produced with a consistent colour while using difficult-to-recycle plastic material that was destined for landfill.
Hand-Crafted Furniture
Our furniture products have been designed and engineered to maximize durability and comfort. We hand-build our furniture products at our zero-waste manufacturing facility.
What is Plastic Lumber?
Plastic lumber is a material made entirely from plastic, mostly HDPE, that looks and feels similar to wood. It doesn’t rot or decay, and it’s great for outdoor projects like decks, boardwalks, and benches. Unlike regular wood, it doesn’t need painting or staining and lasts much longer in harsh weather.
