Turn your factory’s food waste into on-site energy — and a sustainability win
Consistent, high-volume production waste is the ideal feedstock for on-site anaerobic digestion. Flexibuster™ cuts your disposal costs, generates renewable power for the plant, and makes your site a visible leader in your group’s CSR — without unreliable, bolt-on technology.
Built for environmental leadership
- ✓Handles consistent production-line food waste
- ✓Automated & remotely monitored — no new headcount
- ✓On-site electricity & heat for the plant
- ✓Hard CO₂ and cost numbers for your board
Why on-site food-waste recovery just became urgent in the UK
The economics and the law are moving the same direction: keeping food waste out of landfill is no longer optional — it’s a cost, compliance and reputation issue you can get ahead of.
Business food-waste separation is now the law
Since 31 March 2025, England’s Simpler Recycling rules require every workplace to separate food waste from general waste (micro-firms follow by 2027). Wales and Scotland already mandate it — the collection contract is now unavoidable.
Landfill Tax keeps climbing
UK Landfill Tax rises every year and now sits well above £100 per tonne, with gate fees tracking it. Every tonne you process on site is money kept rather than paid away.
Weekly household collections are coming
From 31 March 2026 councils must collect food waste weekly from all homes in England — driving the whole system toward capture and recovery, and demand for local processing.
Since 31 March 2025 every workplace in England must separate its food waste — Flexibuster turns that legal obligation into on-site energy instead of another rising collection contract.
From production waste to plant power in four steps
Flexibuster is a containerised, plug-and-play anaerobic digester that installs on your site with minimal disruption to the line.
Food waste goes in on-site
Your kitchen, canteen or production tonnes of food waste are loaded straight into the containerised unit — no sorting line, no off-site transport.
Automated digestion
Built-in pasteurisation and state-of-the-art sensors break the waste down in a sealed, odour-free anaerobic process, monitored remotely 24/7.
Energy is generated
The biogas produced runs a CHP engine that generates renewable electricity and heat you use on site — cutting both energy and disposal bills.
Biofertiliser is recovered
What’s left is a clean, nutrient-rich biofertiliser — closing the loop and improving soil instead of filling a landfill.
Engineered around what environmental leadership needs
Built around what plant sustainability leaders actually need: innovation they can stand behind, efficiency they can measure, and technology that simply works.
Reliability you can defend internally
The single biggest reason plants hesitate on on-site tech is fear it won’t run. Flexibuster is fully automated, remotely monitored and ISO-certified — so you can champion it to operations without staking your reputation on unreliable kit.
Process efficiency you can measure
Lower disposal spend, on-site energy, and a documented CO₂ reduction — the metrics that prove your sustainability programme is delivering, not just costing.
Make your factory the group benchmark
A visible, award-winning circular-economy system on your site positions you — and your factory — as the sustainability leader other sites in the group are measured against.
Skips and haulers vs. Flexibuster
Third-party waste haulage
- ✕Rising per-ton gate and hauling fees every year
- ✕Trucks, storage and odour on a busy production site
- ✕Zero energy or CO₂ benefit back to the plant
- ✕You’re exposed to someone else’s pricing and schedule
Flexibuster on-site AD
- ✓Up to 40% lower disposal costs within 6 months
- ✓Sealed, odour-free, automated — waste never leaves site
- ✓Renewable electricity, heat and biofertiliser produced on site
- ✓You control the process, the cost and the carbon story
Not all on-site digesters are equal
On-site anaerobic digestion is filling up with newcomers and flat-pack kits. Here’s what to check before you buy — and where Flexibuster is built to win.
Proven, not a prototype
A global fleet, operating across multiple countries for over a decade, has turned thousands of tonnes of food waste into renewable energy. Deployed, field-proven technology — not a pilot or a pitch.
Certified and independently assured
Manufactured to ISO 9001, 14001 and 28001. Many newer entrants can’t show the same quality, environmental and security certification behind the unit.
Fully automated & remotely monitored
Flexibuster runs itself and is monitored by SEaB 24/7 — a hands-off appliance, not a biogas plant you have to learn to operate and babysit.
Purpose-built for food waste
Built-in pasteurisation makes it safe for hygiene-critical sites, and every unit yields both renewable energy and clean biofertiliser — not just volume reduction.
Trusted at the sites that can’t afford to get it wrong
This is not a pilot. Flexibuster has been deployed and operating internationally for over a decade — at hospitals, food and beverage manufacturers, airports, universities and hotels, where hygiene, uptime and reliability are non-negotiable.
A decade in the field
Deployed and operating internationally for over a decade — field-proven technology, not a lab prototype or a risky first install.
Independently validated
Award-winning climate technology, recognised by Blue Earth (BE100) and Envirotech 50, and manufactured to ISO 9001, 14001 and 28001.
Backed by serious institutions
Developed with the support of the EU’s Horizon programme and InnovateUK, and trusted across demanding, highly-regulated sectors.
What plant teams ask us first
Will it disrupt our production line to install?
No. Flexibuster arrives containerised and plug-and-play. It sits alongside your operation and connects to your waste flow with minimal downtime — no major civil works or long build programme.
Our last on-site technology was unreliable. Why is this different?
Every unit is fully automated, remotely monitored by SEaB 24/7, and built to ISO 9001, 14001 and 28001. You get performance data continuously rather than discovering a problem after the fact.
Is our waste volume suitable?
Consistent production food waste is close to the ideal feedstock. Tell us your approximate volume in the form and we’ll model expected energy output, cost saving and payback for your specific site.
How do you prove the CO₂ and cost benefit?
Your site assessment includes modelled disposal-cost savings, energy generation and a documented CO₂ reduction you can put straight into board and CSR reporting.
See the numbers for your factory before you commit
Tell us about your site and we’ll model your disposal-cost saving, on-site energy output and CO₂ reduction — the business case your operations and finance teams will want to see.
