South Dakota Company Recycles Plastic Into Fence Posts | Aberdeen Insider
Many farmers are frustrated with all of the plastic that clutters their farmyards.
Tarps from silage piles, plastic containers, net wrap, totes and drums pile up. It is estimated that 12.5 million tons of agricultural plastic are used annually in the U.S.
A company near Lennox transforms the plastic generated on farms and from other sources into something that every farm needs — 4-inch and 6-inch fence posts. It’s a brilliant example of waste reimagined.
Billy Pollema, vice president of sales for ZahnTech, said the company transforms waste plastic into a product needed by the ag market.
“We sell these posts nationwide, and some have gone to Florida and the Caribbean islands. In those places, they struggle with wood posts rotting due to the salt water and humidity, so this is a good fit for them,” Pollema said.

“Currently, the company processes 30,000 pounds of plastic daily,” he said. “We take it in, shred it, melt it and turn it into something useful. Our goal is to triple what we can process.”
People are thinking more about being sustainable and many want to get to zero waste. The company wants to rebrand recycling and change the way the world views garbage.
ZahnTech is eager to keep plastic out of the landfill.
“We encourage people to bring plastic to us from all over South Dakota. We are even getting some from Wyoming. Our company is partnering with farmers plus different industries. We take it all in as long as it is plastic. There are seven types of plastic in our formulation,” Pollema said.
Trucks constantly pull up to drop off their loads, he said.
“We take chemical jugs as long as they’ve been properly rinsed. We get thousands of barrels from ag companies during the summer and fall, plus plastic pallets,” Pollema said. “We’ve partnered with the city of Beresford to take their curbside pickup materials. Every two or three weeks, it comes to us in bales. They’ll dump it in our shed and we’ll take it from there. We do not accept liquids, glass, metal or hazardous chemicals.”
In addition to ag plastic, ZahnTech is getting semi loads of plastic waste from many industry partners, including Glanbia Nutritionals, which has locations all over the country. Recently, 10 semi-loads of Walmart bags were dropped off. That’s 500,000 pounds of bags waiting to be shredded.
The process uses a primary shredder and a secondary shredder, reducing the plastic to three-eighths inch. Then the material goes through the hot melt extruder and flows into molds for the 4-inch and 6-inch posts.

There’s strong demand for the posts.
“We price them to be competitive with the wood market as farmers don’t want to pay more than they have to. ZahnTech is one of the few companies using this process. In addition to the company in New Zealand, there is one in Canada and one in Pennsylvania,” Pollema said.
He was at the recent Dakota Farm Show in Vermillion showing people the pros of using the posts and explaining what the company does. The plastic posts can replace the green-treated posts or posts treated with creosote to prevent rot. Wood posts normally need to be replaced every 10 years or sooner. ZahnTech information said testing shows their posts will last 100 years.
Business sparked by frustration from lack of plastic scrap recycling options

The owner, Avery Zahn, started the process, and Pollema shared Zahn’s story.
Zahn has owned a pipeline business. His frustration stemmed from the lack of plastic scrap recycling options, forcing him to take the materials to the landfill. After he sold his business, Zahn noticed the railroad ties around his horse arena were rotting and needed to be replaced. Remembering the unrecyclable plastic, he searched for a way to make something usable from it, such as fence posts. He found that in New Zealand, a company developed a process to do that.
“He bought his first extrusion machine from New York, brought it to South Dakota and started figuring out a way to melt the plastic and turn it into fence posts,” Pollema said “Avery tried different formulations and produced a composite to get the posts to the needed strength. After a year and a half of research and development, the company started making and selling products. That was a year and a half ago. It all started with Avery looking at the posts and deciding, ‘I’m going to come up with a better way.’”
The biggest cost for ZahnTech is electricity, with 3,000 amps of service coming into the production facility.
“It’s our major cost and it would be great if we could reduce that, maybe by using some solar power,” Pollema said.

While the electricity is expensive, the plastic is free.
“People are looking for places to get rid of their plastic,” he said. “We are diverting as much from the landfill as possible. It’s a great selling point for our posts as people can see we are doing something good for the environment. For years, people buried plastic, and it will take years to degrade. Many people get behind what we are doing.”
ZahnTech produces 300 plastic fence posts per day
The company produces 300 posts a day with six people in the production line who do the shredding, bundling, receiving material and fabrication. In all, there are 11 employees.
The goal is to handle 40,000 to 50,000 pounds of plastic a day with the two main lines. When ZahnTech adds another line, it will be able to handle 60,000 to 70,000 pounds a day.
Currently, ZahnTech is transforming 98% of waste into sustainable products,” Zahn said.
“We’re not far from achieving our goal — 100% waste conversion. The company wants to build a greener, cleaner world, one fence post at a time,” he said.
On its website, ZahnTech claims its posts are 10 times stronger and 20 times more durable than wood. They are flexible and can be post-driven, cut, drilled, nailed, screwed, bolted or stapled. The posts are fire-resistant, non-conductive, won’t split or rot and are impenetrable by water, frost and pests, per the website. They can also be pulled up and repositioned.

Water hampers growth near Sioux Falls but solution near

DELL RAPIDS, S.D. – Scott Buss can only imagine what this town north of Sioux Falls might have looked like – and how many jobs and taxes would have been generated – if there wasn’t a local shortage of available water.
Buss, executive director of the Minnehaha Community Water Corp., sat in the conference room of the rural water system based in Dell Rapids recently and ticked off the industrial and agricultural projects turned away due to a lack of water.
After hitting its limit on how much water it can provide a few years ago, the rural system has had to turn away proposed projects valued at hundreds of millions of dollars that offered an untold number of new jobs, he said.
The rejected projects include the Agropur Cheese plant that eventually opened in Lake Norden. A few proposed hog farms and dairy expansions in northern Minnehaha County were also stalled, Buss said.

Other proposals, most of which never came to fruition in South Dakota, included the $1.5 billion Gevo corn-based jet fuel plant, the $5oo million Wholestone Farms hog processing plant and a data center that at some point all eyed the Dell Rapids area for development.
“All the water rights are spoken for between Dell Rapids and Sioux Falls, so there was no more water to be had in Minnehaha County,” Buss told News Watch in an interview in June. “With all the (residential) development that was coming in, we realized that our well capacity and our treatment capacity was limiting our ability to take on new high water-use customers.”
Buss and the nonprofit corporation’s board of directors aren’t waiting around to potentially miss out on more opportunities.
In a unique arrangement, the corporation is partnering with the neighboring Big Sioux Community Water System to the north on a $170 million expansion project called Shared Resources. The expansion, started three years ago, will use new wells into the Big Sioux Aquifer to generate 8 million gallons of water more per day starting this fall.
“It’s going to be a huge and great benefit for Big Sioux and Minnehaha water,” said Jodi Johanson, director of the Big Sioux system based in Egan. “This project is going to make sure that down the road we have enough water for the future.”
2 systems get stronger together
The Minnehaha water corporation is still able to bring on new residential and retail customers who consume part of the 9.2 million gallons of treated water it can provide on a daily basis.
The system was formed by a group of farmers and landowners in the 1970s but sought a reliable way of providing more and cleaner water to residents of Minnehaha County outside of Sioux Falls who relied exclusively on individual wells. The system started with about 1,200 customers but has grown to more than 5,500 now in seven cities, mostly north of the Sioux Falls metro area.
Given the limits on water from the aquifer, and balancing the water needs of consistent housing and retail growth in northern Minnehaha County, the water system had to say no to developments that request 1 million or more gallons of water per day, Buss said. A million gallons per day is equivalent to the water consumption of about 4,300 homes, he said.
Billions needed to keep South Dakota taps flowing
South Dakota water systems will increasingly turn to the Missouri River to provide water for future population, agricultural and industrial growth. But plans will require billions of dollars and decades of construction to keep taps flowing freely.
As with other rural water systems in South Dakota, the aquifers the systems rely on for their water are either running low or are legally tapped out, or both.
In the case of Minnehaha water corporation, the Big Sioux River Aquifer has gotten drier, but state law is also preventing it from taking more water from the aquifer.
In 1996, the state Water Management Board allocated water rights, or withdrawal limits, to systems that take groundwater from the aquifer, Buss said.
Those limits have now been reached, meaning that Minnehaha water cannot take any more than the 7 million gallons per day it is drawing now.
The system also receives about 2 million gallons per day from the Lewis & Clark Regional Water System, making its daily maximum capacity of about 9.2 million gallons per day, which it sometimes reaches, especially during spring planting season or hot summer months.
Directly to the north, the Big Sioux Community Water System produces up to 2 million gallons per day for about 2,400 customers in Moody and Lake counties as well as some in Brookings County and in western Minnesota, Johanson said.
The system still has room within its water rights to draw more water, making it an attractive partner for Minnehaha water.
Though Big Sioux Community Water System has not turned away any large projects, it needs more water to serve a boom in residential growth in the region, Johanson said.
In the area around Lake Madison, near Madison, developers are considering projects that could someday bring 500 new homes and a new nine-hole golf course, she said.

The system also serves a number of dairies that use significant water and provides water to the Dakota Ethanol plant in Wentworth, which is undergoing an expansion. Farmers in the region are also using greater quantities of water to deliver chemicals onto their land, Johanson said.
“This is our first expansion,” she said. “We’re looking forward and we’re trying to find the solution before we face a problem.”
Federal government and customers pay the way
The biggest Shared Resources ticket item is a new $80 million water treatment plant that is nearly completed on 240th Street a few miles north of Dell Rapids.
A 20-inch pipeline from the plant to the east will end at a 1.5 million gallon water tower, and a 24-inch pipeline to the west will terminate at a ground-level storage tank with a 4 million gallon capacity.
Six new wells will draw the water, and the storage tanks will provide both pressure and the ability to adapt to changing demands without service interruption, Buss said.
As with most modern water projects, the costs will be shared by government and end users. The systems are funding the project with $49 million in grants from the Biden-era American Rescue Plan Act and $121 million in low-interest loans from South Dakota’s Drinking Water State Revolving Fund.
The two systems are sharing the cost of the project loans commensurate with how much water they will receive, meaning Minnehaha will pay 65% of the costs for its 5 million gallons per day while Big Sioux will kick in 35% for its 3 million gallons more per day.
Minnehaha water is assuming $87 million in new debt and Big Sioux will take on $42 million in new debt, Buss said.
The average residential consumer in both systems that uses about 7,000 gallons per month will see their bill rise to $135 a month, roughly double the cost in 2020.
“It’s a big project, and it’s a good example of how two systems can work together to have some economies of scale,” Buss said.
Ratepayers will see a significant increase in their monthly water bills. The average residential consumer in both systems that uses about 7,000 gallons per month will see their bill rise to $135 a month, roughly double the cost in 2020, Buss said.
A big project, but even more water needed
But both systems view the Shared Resources project as a temporary fix and both are looking toward proposed projects that will tap the Missouri River for more water in the future.
Buss said his system has applied for 10 million gallons more water per day from Lewis & Clark, which has two expansion efforts planned.
Minnehaha water has simultaneously applied to receive 10 million gallons per day from the proposed Dakota Mainstem Regional Water System, a potentially $10 billion project to carry Missouri River water to more than 50 communities and organizations across eastern South Dakota and parts of Minnesota and Iowa.
The dual application effort is to make sure Minnehaha water can rely on taking in more water from at least one of the two systems as they come online, Buss said.
Johanson said Big Sioux has also signed on to accept water from Dakota Mainstem, even if it takes 20 to 40 years for the water to begin flowing.
To ensure that steady supply of high-quality drinking water, four major projects are in progress to take more water from the Missouri River – including WEB Water in the northeast, Lewis & Clark and the proposed Dakota Mainstem in the southeast as well as the proposed Western Dakota Regional Water System in western South Dakota and the Black Hills.

The projects are part of a wide-scale increase in water service capacity now underway in South Dakota, where water managers of several systems are implementing plans to serve the state for the next 40 to 50 years.
Regional rural water systems such as Minnehaha and Big Sioux are critical components of those projects because they provide water to communities and individual customers at the end of the delivery system.
Alicia Deschepper, zoning administrator for Moody County, said the water system expansions should allow for more growth to occur in Moody and Minnehaha counties, which are seeing new single-family housing developed at a rapid rate.
“I think it will be a great thing for our county and hopefully enable us to bring in more bigger businesses as well as more homes,” Deschepper said.
