Forever Fence Posts Made From Plastic
Thanks to a South Dakota manufacturing company, the next fence posts you install may never need to be replaced. Sustainable Products, Inc. makes posts out of recycled plastic with a UV stabilizer that won’t rot in the ground or deteriorate in the sun. That’s great for consumers and the environment because it makes something useful out of plastic (1,600 water bottles per 4-in. post, for example) instead of piling up in a landfill.
“Other companies recycle plastics and make products but often take only specific plastics. The difference with Sustainable Products is we take lightweight plastic films, plastic bags, and heavy-walled plastic from P1 to P7. We aren’t turning anything way,” says Billy Pollema, Vice President of Sustainable Products.
By taking all plastic, the company helps manufacturers and municipalities, who usually have to pay to remove scraps and waste. That was the reason Avery Zahn started Sustainable Products. Previously the owner of a pipelining business, Zahn worked on shredding, blending, and extruding plastics and other waste material and eventually perfected the formula that combines these recycled waste products into sustainable/useable products.
“Our goal is to consume as much raw wasted plastic material as possible and form it into end-user products. With this goal, we hope to reduce waste going into landfills and provide a quality product for the end consumer,” Zahn posted on the business website.
Production on extruding fence posts started in late 2023. The 7-ft-6 in. square posts retail for about $25 and weigh 41 lbs. The 8-ft., 6-in. round and square posts weigh 98 lbs. and sell for $52.
With tapered or blunt ends, they can be installed like wooden posts by pounding or augering holes. They use the same staples or other fasteners as wood posts to secure wire.
“Their compression strength is three times that of a wood post, and they have 10 times the tensile strength of wood. They’ll still flex and won’t rot,” Pollema says. Posts installed at a ranch in Florida for a year look as good as when they were new.
The company has also made 2 by 4s and 2 by 6s and hopes to add other products. They sell retail, but the goal is to wholesale to retailers.
Working with businesses and cities in South Dakota and adjacent states as far as 200 miles away, who save money transporting plastic to the Lennox, S.D., warehouse/plant, there’s a steady supply stream, Pollema says. The manufacturing plant currently goes through 15,000 lbs. of plastic waste per day, and there are plans to add equipment to triple that.
Discounted prices are available for large orders. Customers can order from the company, and dealer inquiries are welcome.
