Turn kitchen and buffet waste into on-site energy — and a greener guest story
Hotel kitchens, buffets and banqueting generate food waste around the clock. Flexibuster™ processes it on site — discreetly and odour-free — cutting your disposal costs, generating renewable energy for the property, and giving you real green credentials guests and corporate clients now expect.

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 kitchen waste to hotel energy in four steps
Flexibuster is a containerised, plug-and-play anaerobic digester that installs back-of-house with minimal disruption to guests or operations.
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 hospitality operations and brand
Space is tight, guest experience is everything, and green claims have to be real. Flexibuster is built around all three.
Discreet and space-efficient
The containerised unit fits back-of-house and runs sealed and odour-free — so it never touches the guest experience while quietly removing your food waste on site.
Cut the cost of high daily volumes
Kitchens, buffets and banqueting produce a lot of food waste. Processing it on site cuts disposal costs by up to 40% within six months and generates energy for the property.
Green credentials that are actually true
Guests, event bookers and corporate clients increasingly demand real sustainability. On-site AD is a substantive, verifiable claim — not greenwashing — backed by auditable CO₂ and diversion data.
Waste haulage vs. Flexibuster
Off-site waste collection
- ✕Rising per-lift and disposal fees on high volumes
- ✕Bins, storage, smell and vehicle movements on site
- ✕Sustainability claims you can’t fully back up
- ✕No energy benefit to the property
Flexibuster on-site AD
- ✓Up to 40% lower disposal costs within 6 months
- ✓Discreet, sealed, odour-free — processed on site
- ✓Verifiable CO₂ and diversion data for your brand
- ✓Renewable electricity and heat for the property
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 hospitality operators ask us
Will guests ever notice it?
No. The unit sits back-of-house and runs fully sealed and odour-free, so it stays invisible to the guest experience while removing your food waste on site.
We’re tight on back-of-house space. Will it fit?
Flexibuster is containerised and compact. Share your property details in the form and our team will confirm siting and connection during your site assessment.
Can we use it in our sustainability and sales messaging?
Yes — and credibly. You get auditable data on waste diverted, CO₂ avoided and energy generated, so your green claims to guests, event bookers and corporate clients are backed by real numbers.
How much can we actually save?
Customers cut disposal costs by up to 40% within six months while generating on-site energy. Tell us your volumes and we’ll model the payback for your specific property.
Model the savings and the green story for your property
Tell us about your hotel and we’ll model the disposal-cost saving, on-site energy output and CO₂ reduction — plus the sustainability credentials you can put in front of guests and clients.
