Why this matters
Anaerobic digestion and RNG projects get planned around generic municipal food-waste estimates, and then choke on contaminated, unpredictable feedstock. The core thesis of this research: food waste should be stabilized, cleaned, measured, and quality-controlled close to where it’s produced, and digesters should be sized around verified feedstock density within a cluster. The real question isn’t where to put digesters. It’s what physical network should exist between producers, preprocessing assets, haulers, AD facilities, and energy offtakers.
What exists now
This is currently a research thread, and honestly staged as one:
- A research charter with a testable hypothesis (near-site preprocessing → cleaner, more bankable feedstock, better haul economics)
- A “decentralization ladder” framework: six intervention levels from source separation to shared preprocessing hubs, matched to generator types
- Target-generator analysis: grocery distribution hubs, big-box retail, processors, campuses first
- A growing pile of academic and industry literature being worked through
The hypothesis is being tested honestly against the boring alternatives: centralized depackaging, direct hauling, composting, or existing capacity may simply be cheaper in many markets.
What I’m looking for
People inside the industry: AD/RNG developers, organics haulers, waste brokers, grocery sustainability leads, or municipal organics planners. Thirty minutes of ground truth beats a week of desk research.
Open questions
- Which cluster type reaches viable scale first: retail plazas, campuses, or processor corridors?
- Is the wedge a preprocessing service, a development model, or a feedstock data layer?
- Who pays first: the generator (compliance), the hauler (route density), or the developer (bankability)?
