Building a sustainable future,
one generation at a time
Turning waste into UK-grown protein and better farming inputs.
Family-led. Science-backed. Operationally proven.
FKS is a UK insect biotechnology and commercial biorefinery company, transforming Black Soldier Fly biomass into high-value ingredients, sustainable products, and licensable technologies for global markets.
Built on generations of argicultural experience
Driven by biotechnology. Powered by the circular economy.
FKS is built on proven principles, tested rigorously against the highest standards of operations.
Upcycling 40,000 tonnes of contracted food waste, sourced within a 15-mile radius
120,000sqft facility in South Lincolnshire’s UK Food Valley
Protein, soil improver, bio-oil, and polysaccharides
Insect farming is alive and thriving
We don’t theorise about insect farming.
We do it. Every day, across a facility built to last generations.
Square feet operational
Production sites live
Largest in Europe
Mile sourcing radius
Practical, not speculative
We chose proven industrial systems and rebuilt them to our standards, commissioning production in measured steps to protect uptime and bank learning.
Circular by design
Waste, much of which would otherwise be incinerated or committed to landfill, becomes clean inputs for UK supply chains — with multiple outputs and clear routes to market.
Trust, built in daylight
We have set food-grade standards for the industry, with full traceability. We work in partnership with APHA (Animal and Plant Health Agency) and Trading Standards to help set credible benchmarks.
Two urgent problems. One circular solution.
The UK produces millions of tonnes of surplus food waste, and too much still ends up releasing land based emissions.
At the same time, farming relies heavily on imported protein feed with locked-in emissions and fragile supply chains. We use bioconversion to turn organic waste into valuable products that support a more resilient UK food system.
Investors & Funders
Support a circular economy, support a UK-first.
Waste suppliers
Food waste turned measurable circular outcomes, with reporting and transparency built in.
Feed customers
UK-sourced, traceable protein with supply security and science-led production.
Trusted partners who know the difference
Meet our people
Experience meets innovation, expertise meets dedication.
Our team unites decades of experience in environmental finance, food processing, and entomology, with a shared belief that UK agriculture needs better solutions.
Practical insights. Fewer buzzwords. More proof.
If you’d like to see the operation first-hand, we’d love to show you around — and talk through how we work, what we produce, and where we’re headed next.
