From Field to Foot: Making Hemp Socks in Poland
Industrial Hemp Podcast
This week’s Hemp Show takes us once more back to Poland, where Maciej Kowalski gives us a tour of his vertically integrated hemp textile company in Elbląg, a small town in Northern Poland, not too far from the Baltic Sea. Today we'll let Kowalski guide us as we tour the Kombinat Konopny facility. His approach to business is straightforward: Make things people need. "What do they need? They need socks. They need beanies, they need pants, they need blouses, they need shirts, everything," Kowalski said. "The sock became like the symbol of what we're trying to achieve seven, eight years ago...

Hempcrete Hero: Little House on the Podcast
Industrial Hemp Podcast
We have an outbuilding at home — we call it the Little House. It's a small old barn that sits out in our back yard, maybe 25 feet from the back door. It was a barn for animals at one point, then a garage, then an apartment. There's a lot of interesting energy in the Little House. It's been many things over the years: an art studio, a bakery, a jewelry-making place. By 2018 the Little House had given birth to this very podcast. The Little House has been an epicenter of entrepreneurial spirit and love for a long time. When I got home from , I found out there was a water leak in the Little...

Encore Presentation of Michael Klepacz's First Interview on Hemp Show, March 2024
Industrial Hemp Podcast
This is a special encore edition of an interview we published on YouTube two years ago. This is my conversation with Michael Klepacz, an Ohio native and Air Force veteran who moved to Poland in 2012 and founded Natural Materials Unlimited, a company that makes textiles and products from hemp, linen and other bast fibers. In this bonus episode, he talks about how the business grew from hemp wick to guitar straps, pet accessories and custom fiber products for clients around the world. The conversation digs into long fiber versus short fiber hemp: why long fiber produces stronger, higher-quality...

Michael Klepacz: An American in Warsaw
Industrial Hemp Podcast
This week on the Hemp Show, we continue our , catching up with American expat Michael Klepacz, owner of Natural Materials Unlimited. Klepacz sits near the end of the hemp supply chain — he doesn't grow or process raw fiber himself. Instead, he sources hemp and other natural fibers from regional mills and turns them into finished goods, from hemp wick to dog leashes, as a contract manufacturer for brands worldwide. Klepacz gives us a walking tour of his factory — beeswax, waxing lines and a dynamometer that tests twine strength — and makes the case for hemp as Europe's best fiber. We're...

Ken Elliott & Rusty Peterson — What US Hemp Can Learn From Europe
Industrial Hemp Podcast
This is part one of a ten-part podcast series documenting the European Industrial Hemp Association's 23rd Annual Conference in Poznan, Poland, at the Institute of Fiber Plants and Medicinal Medicine, June 10-12. The series starts with a casual conversation with Ken Elliott and Rusty Peterson from IND HEMP in Montana about the conference itself and how it compares to hemp events back home. "The professionalism that they bring, the fact that they've been doing things instead of talking about things in Europe is a big difference,“ Elliott said. Both Elliott and Peterson spoke at the...
info_outlineThis week on the show we talk with Ken Meyer of Complete Hemp Processing in Winfred, South Dakota. As of last week, Meyer is also a co-founder of Renewabuild Great Plains — the first U.S.-licensed manufacturer of structural hempcrete blocks.
We've been telling the story of these structural blocks for a long time on the podcast. We first encountered them back in 2019 — they look like giant Lego blocks and work much the same way — at the Pennsylvania Farm Show, where the Pennsylvania Hemp Industry Council had them on display.
Back then, the blocks were made by a Canadian company called Just BioFiber in Alberta. Today, the technology is licensed and administered by another Canadian company, Renewabuild Field to Form, which has made improvements to the original design of the block.
The structural hemp blocks differ from traditional hempcrete construction because their internal frame makes them load-bearing in a way that spray-applied or cast-in-place hempcrete cannot offer.
"It has a frame inside it. It's a glass-filled biocarbonate frame ... and then the hempcrete is pressed around it," Meyer said. "And that frame provides a structure in the wall. So that makes the block a structural block, and the block itself in a wall system replaces the sheet rock, the insulation and the timber."
The story of the blocks continues now, as the first U.S. company prepares to manufacture them at a plant in Rock Valley, Iowa.
"At Complete Hemp Processing in Winfred, South Dakota, we decorticate hemp stocks. And we need a place to sell the hemp hurd. And our farmers need us to have a place to sell hemp hurd so they can put hemp in rotation with corn and soybeans," he said.
This is how an industry scales. Dedicated, passionate people working tirelessly to build a supply chain.

The Lancaster Farming Industrial Hemp Podcast returns this week with an interview featuring Ken Meyer, owner of Complete Hemp Processing in Winfred, South Dakota, and one of three co-founders of Renewabuild Great Plains — the first U.S.-licensed manufacturer of structural hempcrete blocks. Host Eric Hurlock sits down with Meyer to discuss the new hempcrete block factory being built in Rock Valley, Iowa, the long journey of the structural hemp block from Canada to the United States, and what this milestone means for the American industrial hemp industry, hempcrete construction, and the future of sustainable building materials.
Renewabuild Great Plains is the first U.S. company to license the structural hempcrete block technology developed by Just BioFiber of Alberta, Canada, and now administered by Renewabuild Field to Form. Unlike traditional hempcrete construction methods — including spray-applied hempcrete and cast-in-place hempcrete — the Renewabuild block features an internal glass-filled biocarbonate frame, making it a load-bearing structural wall component. A single block replaces sheetrock, insulation, and timber framing in one product, offering builders, architects, and engineers a scalable, lower-carbon alternative to conventional wall systems with improved fire resistance, durability, and building-envelope performance.
The new Rock Valley, Iowa hempcrete block factory is scheduled to receive its equipment in December 2026 or January 2027, with the capacity to produce two blocks a minute, more than 900,000 structural hempcrete blocks per year running three shifts. At full production, the facility will manufacture enough wall material for roughly 500 perimeter walls of 2,000-square-foot homes annually. The factory's entire production equipment fits inside two shipping containers, making the model regionally scalable across the United States — a key part of Renewabuild's strategy to support local farmers, local hemp processors, and local hempcrete construction supply chains. Meyer is joined as co-founder by John Peterson of Dakota Hemp and Bill Brehmer of Renewabuild Great Plains, alongside a group of Iowa farmers who have invested in the project.
This episode of the Lancaster Farming Industrial Hemp Podcast also revisits archival audio from January 2019, when Pennsylvania hemp historian Les Stark first introduced the Just BioFiber structural hempcrete block at the Pennsylvania Farm Show, alongside the original podcast interview with Just BioFiber co-founder Michael D. Champlain. Listeners will also hear from David Geertz of Renewabuild, recorded at the International Hemp Building Symposium at Kansayapi in Minnesota. Plus, host Eric Hurlock follows up on last week's interview with Pennsylvania farmer Steve Groff with a statement from the Pennsylvania Department of Agriculture regarding agricultural innovation grant reimbursements.
