In addition to the benefits mentioned, the use of digestate offsets the use of synthetic fertilizers, and the emissions associated with their production
@DMT had a great article on this topic in last year’s Biogas Community Magazine on Safety! Their upgrading technology aims to preserve operational integrity and mitigate potential threats from a cybersecurity perspective.
Anything to add @Nikolas_Pat ?
I think a significant limiting factor at the moment is that, as an underutilized technology, implementing it carries a high production cost. Long-term offtakers are required to show the new revenue from the technology makes the increased CAPEX worthwhile.
I would love to hear from some of the other folks already leading the way with this: @sysadvance_joaquim @Ilir
I wonder if any CHP providers could share their solutions 🤔
@PlanET @ClarkeEnergy @abgroup_mihalThere are some excellent solutions from @Bauer , @ACS , @adicomp_luca , and @adekom
Maybe our desulfurization experts could weigh in here? @Nikolas_Pat @Paques @pyro-green-gas @unison_bobbie @UGN @desotec_louis
@Anka.Enerji I wonder if you might be able to share some of the nuances of pretreatment? Is there a “one-size-fits all” solution? or is there variation between projects? 🤔
I wonder if some of the folks operating in this space @Bright @prodeval_raphael @Sysadvance might be able to share their experiences?
Do any of our desulfurization experts from @Anka.Enerji , DMT @Nikolas_Pat or @Paques @desotec_louis want to jump in on this?
Some main developments within the Spanish market were reviewed by Francisco Repullo Almagro from AEBIG and Ines Hedan from @Methalac in BIogasWorld’s Spanish market webinar earlier this year!

Looking towards the future, I think we’re going to find out whether many of the technologies currently being piloted, such as woody biomass to RNG, and technologies making lignocellulosic materials more anaerobically digestible, are commercially viable, and if so, new investments will likely support these endeavours.
In terms of policy, the industry still requires a uniform recognition of its benefits. The ability to valorize the entire value chain, including digestate and CO2, is increasingly being recognized. I believe policy-wise, in North America, the next 5 years will feature more state and provincial governments formally recognizing these benefits, which will in turn open new markets for AD facilities and allow the market to flourish
Hey! At least in the US, several developers have, or currently are, developing poultry litter projects. Some of these companies include DVO, GESS, Eagle Green Energy, Agro Development Partners, and Green Energy Solutions.
One of the main challenges of poultry litter is its high nitrogen content, which requires additional steps for removal in gas pretreatment stages
California has traditionally been a state of interest, due to the LCFS bringing long-term revenue potential for RNG projects, however, there are a number of emerging state markets offering new incentives.
Washington is one such market that offers grants for landfills that install equipment to reduce their emissions, and Florida recently passed new legislation for a framework for RNG investment.
On the renewable fuels front, Washington & Oregon have for a number of years offered low carbon fuel standards of their own, and in 2024, New Mexico joined them with their own program, offering RNG a new credit market. Several states are currently pursuing clean fuel standards of their own, including Illinois, Hawai’i, Minnesota, and Michigan.
Small projects can absolutely be economically viable; they just require a different range of solutions than large-scale projects.
Collaboration is a key tool for farms close to other farms. Farms can collaborate, either sharing a large digester system or individual digesters, with centralized upgrading for RNG. These collaborative projects are key for regions where small agricultural producers dominate, and developers such as Coop Carbone in QC already demonstrate the success of this model.
Another avenue for remote farms or regions is to pursue CHP and local energy use. Several companies provide small-scale solutions for AD projects.
Very interesting! Thanks for sharing, John
