Greenlane Wins Multi-Unit Order for Biogas Desulfurization Equipment

Aug 07, 2024

Greenlane Renewables Inc. ("Greenlane" or the "Company") (TSX: GRN) (FSE: 52G) today announced that its wholly-owned subsidiary Airdep S.r.l. has signed a multi-unit purchase agreement with a repeat customer in Europe valued at €1.3M million ($2 million) for biogas desulfurization equipment. These units are engineered to remove hydrogen sulfide (H2S) from raw biogas to protect downstream equipment.

Greenlane manufactures biogas desulfurization equipment for a variety of end uses including biogas-to-biomethane and biogas-to-power systems for the global market. In North America, the Company markets its biogas desulfurization equipment under the Greenlane Cascade H2S brand and under the Airdep DBC brand for the rest of the world.

"Winning a new contract for multiple biogas desulfurization units in Europe underscores our breadth of offerings and the demand for our advanced technologies," said Ian Kane, President & CEO of Greenlane. "We are well-positioned to deliver innovative solutions to our clients worldwide, particularly as these biogas desulfurization products can be sold on their own or in conjunction with Greenlane biogas upgrading systems."

Every biogas project requires H2S removal. Our biogas desulfurization product line delivers an established, robust and cost effective regenerative solution where the goal is low operating expense.

Our biogas desulfurization technology includes the following process steps. First, the raw biogas feeds into the bottom of a scrubbing tower where it flows, countercurrent, to a proprietary chemical solution where treated gas exits through the top of the scrubber. Next, the sulfur-rich solution is regenerated in a separate oxidation tank. Then the regenerated solution is transferred to a sedimentation tank to separate the elemental sulfur solids. Finally, clean, regenerated solution returns to the scrubbing tower in a continuous and efficient process.

Our biogas desulfurization products are easy to install and operate and eliminate many of the operational issues and costs that come with traditional biological scrubbing and media-based H2S removal systems. The elemental sulfur solids created in the removal process can be spread on fields as fertilizer.

Video: From Conventional to Regenerative: Will Groeneveld’s Journey Back to the Land

"You realize you've got a pretty finite number of years to do this. If you ever want to try something new, you better do it."

That mindset helped Will Groeneveld take a bold turn on his Alberta grain farm. A lifelong farmer, Will had never heard of regenerative agriculture until 2018, when he attended a seminar by Kevin Elmy that shifted his worldview. What began as curiosity quickly turned into a deep exploration of how biology—not just chemistry—shapes the health of our soils, crops and ecosystems.

In this video, Will candidly reflects on his family’s farming history, how the operation evolved from a traditional mixed farm to grain-only, and how the desire to improve the land pushed him to invite livestock back into the rotation—without owning a single cow.

Today, through creative partnerships and a commitment to the five principles of regenerative agriculture, Will is reintroducing diversity, building soil health and extending living roots in the ground for as much of the year as possible. Whether it’s through intercropping, zero tillage (which he’s practiced since the 1980s) or managing forage for visiting cattle, Will’s approach is a testament to continuous learning and a willingness to challenge old norms.

Will is a participant in the Regenerative Agriculture Lab (RAL), a social innovation process bringing together producers, researchers, retailers and others to co-create a resilient regenerative agriculture system in Alberta. His story highlights both the potential and humility required to farm with nature, not against it.
