Food waste & organics co-digestion to energy
Organics Digestion! The Future of RNG
Organics Digestion! The Future of RNG is a multi-part webinar series presented by HoSt Bioenergy Systems North America. Hosted by Jorgen Gilbertson (Sales Engineer & Brand Ambassador) with recurring guest speaker Danny Husband (Global Manager Operations, Biogas Realization), the series draws on real project experience across Europe and North America to give developers, municipalities, and operators practical guidance on organics co-digestion.
5 Mistakes That Kill Organics Projects (and How to Avoid Them)
Now available for on-demand viewing!
We joined forces with our partners Mavitec and Nijhuis Saur Industries to map out the most common mistakes that separate bankable organics RNG projects from stalled ones.
The result is our webinar “5 Mistakes That Kill Organics Projects (and How to Avoid Them)” — and if you missed the live presentation, it is now available for on-demand viewing.
In this presentation, Jorgen Gilbertson (Sales Engineer, HoSt North America) and Danny Husband (Global Manager Operations, Biogas Realization) are joined by special guest presenters:
• Marie Esteve, Global Industry Leader, Waste to Energy/Biogas, Nijhuis Saur Industries
• Koen van Veldhuisen, Manager Sales, Mavitec
In addition, Jorgen sits down with Robert Lems (CEO – HoSt North America) and Graham Hartlett (Chief Sales Officer, HoSt North America) to discuss the challenge of overly optimistic project timelines.
Case Studies on Organics Co-digestion Projects
In part 1 of our Organics Digestion! The Future of RNG series, presenters Jorgen Gilbertson, HoSt Sales Engineer and Brand Ambassador, and Nina Wohlfahrt, Sales Manager and Technical Subject Matter Expert, present “Case Studies on Organics Co-digestion Projects”. Jorgen and Nina are joined by Guest Speaker Danny Husband, Global Manager Operations, Biogas Realization.
In the on-demand webinar the team shares insights into how well designed co-digestion facilities can successfully integrate food waste, manure, and agricultural residues, while meeting regulatory requirements and maintaining profitability.
Back to the Future: What the UK Organics Digestion Market Reveals About America’s RNG Opportunity
Lessons from the UK’s organics digestion market could help shape America’s RNG sector.
In Part 2 of our Organics Digestion webinar series, Jorgen Gilbertson and Danny Husband unpack what US developers can learn from the UK’s experience—especially around front-end processing, process stability, and realistic operating costs—to design facilities that are more robust, flexible, and future-proof from day one.
What We Mean by "Organics" and "Co-Digestion"
When HoSt refers to organics, we mean the biodegradable waste streams that can be processed through anaerobic digestion — depackaged food waste, source separated organics (SSO), agricultural residues, fats oils and greases (FOG), and similar materials. These feedstocks are distinct from manure-based inputs, and each brings its own handling requirements, pre-treatment needs, and process considerations.
Co-digestion is the practice of combining multiple organic waste streams within a single digester to optimize performance. Rather than relying on a single feedstock, a co-digestion facility blends complementary inputs to balance nutrient ratios, stabilize microbial activity, and maximize biogas yield. The challenge — and the expertise — lies in managing that blend continuously. Feedstock quality shifts daily. Introduce a new stream too quickly, and the microbial biology inside the digester needs time to adapt. Get the balance right, and the results are consistently strong gas production, better digestate quality, and a facility model that can be replicated.
This distinction matters. Not all organic waste is equal — and not all anaerobic digestion is co-digestion. The feedstock mix you design for determines everything downstream: pre-treatment equipment, digester sizing, gas yield projections, and the long-term commercial model.
HoSt operates its own in-house laboratory for biochemical methane potential (BMP) testing and continuous feedstock analysis, validating how new inputs will perform before they ever enter a live digester. Every feedstock we process has been screened, tested, and introduced deliberately.
