Redrock Feedstock strategy
Securing and blending the right organic streams for stable, high-yield digestion, grounded in real contracts, contamination and seasonality rather than optimistic assumptions.
Anaerobic digestion & biomethane
The proven core, done properly.
Anaerobic digestion is where Redrock started, and it remains the backbone of what we do. We develop food- and agriculture-fed AD and biomethane projects end to end, grounded in the operational and microbiological reality that decides whether a plant performs.
- Feedstock strategy
- Biomethane to grid
- CHP, power & heat
- Biofertiliser
- Operations & optimisation
What we do
The full chain, feedstock to field.
Digestion & biogas
Process and plant design built on how the biology actually behaves, so the plant performs in operation and not just on paper.
Upgrading & grid injection
Cleaning biogas to grid-quality biomethane and getting it into the network under the right commercial and certification framework.
Energy, power & heat
On-site renewable gas, power and heat via CHP where grid injection is not the route.
Biofertiliser & nutrients
Turning digestate into a valuable, compliant soil product and recovering nutrients rather than creating a disposal problem.
Why it works
Not just another AD developer.
Microbiology-first
Plants live or die on the biology. We design, commission and troubleshoot from the microbiology outward, not from the equipment datasheet inward.
Feedstock realism
Real feedstock contracts, real contamination and real seasonality. We size and de-risk projects against what actually arrives at the gate.
An operator’s eye
Designed by people who have run AD plants, for the people who will run them, with reliability, safety and uptime built in from the start.
How we deliver
Concept to close, and into operation.
An in-house development team, supported by specialist partners, takes AD and biomethane projects from feedstock strategy and site selection through design, consenting and financing to a built, operating asset.
And because anaerobic digestion sits alongside our supercritical and sustainable-fuel work, we can see where AD is the right answer, and where it isn’t.
Have feedstock or a site in mind?
Whether it’s a new AD project or an existing plant that isn’t performing, let’s talk.
