Cut your hospital’s waste costs and carbon — with energy resilience built in
Hospitals run 24/7 kitchens and canteens that generate constant food waste. Flexibuster™ processes it on site — odour-free and hygienically — turning a disposal cost into resilient on-site power and measurable progress against your net-zero targets.
Built for estates & sustainability leads
- ✓Sealed, pasteurised, odour-free — safe near care settings
- ✓On-site electricity & heat for energy resilience
- ✓Hard evidence for net-zero reporting
- ✓Automated — no burden on clinical or estates staff
Why on-site food-waste recovery just became urgent in the EU
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.
Separate bio-waste collection is now the law
Since 31 December 2023, Article 22 of the EU Waste Framework Directive requires bio-waste to be separated at source in every member state — the era of mixing food waste into general refuse is over.
Landfill is being designed out
The EU Landfill Directive caps municipal waste to landfill at 10% by 2035, and national landfill taxes and gate fees climb every year. Diversion is no longer optional.
Bio-waste is Europe’s biggest wasted resource
Bio-waste is the largest single stream of municipal waste, yet most of it is still landfilled or incinerated instead of recovered into energy and biofertiliser on site.
Bio-waste is the key to the recycling targets in the Waste Framework Directive and the landfill-diversion targets in the Landfill Directive — Flexibuster lets you meet both, on your own site, without a third-party hauler.
From canteen waste to hospital power in four steps
Flexibuster is a containerised, plug-and-play anaerobic digester that installs on your estate with minimal disruption to a live site.
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.
Designed for the realities of a live healthcare estate
Hygiene, resilience and accountability come first in healthcare. Flexibuster is engineered around all three.
Hygienic and odour-free by design
A built-in pasteurisation stage and fully sealed process mean food waste is handled safely and without odour — essential anywhere near patients, kitchens and public areas.
On-site energy resilience
The biogas generates electricity and heat you use on site, adding a layer of energy resilience for a facility that can never afford to go dark — while cutting energy bills.
Evidence for your net-zero plan
Documented waste diversion, CO₂ reduction and renewable-energy generation feed straight into the NHS Net Zero commitment and board-level sustainability reporting.
Clinical & food-waste haulage vs. Flexibuster
Off-site waste collection
- ✕Recurring, rising collection and disposal contracts
- ✕Waste storage, vehicle movements and odour risk on site
- ✕No energy or resilience benefit to the hospital
- ✕Diversion you can’t fully evidence or control
Flexibuster on-site AD
- ✓Up to 40% lower disposal costs within 6 months
- ✓Sealed, pasteurised, odour-free — processed on site
- ✓Renewable electricity and heat for the estate
- ✓Auditable diversion and CO₂ data for net-zero
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 healthcare estates teams ask us
Is it safe to operate near patients and kitchens?
Yes. The process is fully sealed with a built-in pasteurisation stage, so it’s odour-free and hygienic — designed to sit within live, occupied sites including healthcare estates.
Will it add work for our clinical or estates staff?
No. Flexibuster is fully automated and remotely monitored by SEaB. Your team feeds in food waste; everything else runs and reports automatically.
How does it help our net-zero commitment?
You get auditable data on waste diverted, CO₂ avoided and renewable energy generated — exactly the evidence estates and sustainability teams need for net-zero and board reporting.
We have limited space on a busy estate. Will it fit?
The unit is containerised and compact. Share your site details in the form and our team will confirm siting and connection during your site assessment.
