Scotland’s food and drink sector has always been defined by quality from distilleries and dairies to seafood and fresh produce. It’s a cornerstone of the Scottish economy.

We know that across the country producers are putting real effort into making their operations more efficient and sustainable, often finding practical ways to use every part of what they make.

But even in the best-run operations, surplus and by‑products are part of food production. Waste, in other words, is unavoidable.

The power of food waste
Across Scotland, food manufacturers, processors and councils are already proving that food waste can do much more than fill bins. Did you know that material we call ‘waste’ can actually end up powering homes and feeding farmland? Through anaerobic digestion (AD), it becomes biogas for renewable energy and biofertiliser.

Picture it simply: food waste breaks down to create biogas, which turns into electricity or gas for the grid. What’s left is a natural fertiliser, ready for fields and crops. No fuss, just a practical loop.

In the UK, over 10 million tonnes of food waste are generated yearly, but a small percentage gets recycled or turned into energy. That leaves a lot of potential on the table; enough to cut emissions and generate power for thousands of households.

Why it matters in Scotland
This approach lets Scottish producers turn unavoidable waste into a valuable resource, a practical way to make operations even more sustainable while keeping value local.

The loop looks like this: food is grown, processed and eaten; unavoidable waste is collected and turned into energy; the remaining nutrients go back to the land to grow the next crop.

The Scottish food sector is built for this. Strong farming ties, short regional supply chains, and a real push on circular economy mean it’s not some far-off idea. Local councils are already collecting food waste, and AD plants are dotted across the country with solid partnerships in place.

Scotland has also been ahead of the curve when it comes to food waste policy. Regulations requiring businesses to separate food waste have been in place for over a decade, positioning Scotland as an early mover in recognising food waste as a resource. This early action has helped build the infrastructure and behaviours needed to support a more circular system; from segregated collections to established anaerobic digestion capacity.

Bio Capital’s role
At Bio Capital we’re in the thick of it; transforming food waste from homes and businesses like yours, into renewable energy, at our AD facilities.

Last year alone, we handled over 500,000 tonnes, generating enough gas to heat nearly 20,000 homes and enough electricity to power almost 65,000.

Specifically in Scotland, we transformed enough food waste to power over 30,000 Scottish homes.

Compared to landfill, processing this food waste through AD saves over 345,000 tonnes of CO₂ annually – the equivalent to removing 240,000 cars from the road.

Bringing the process to life
Bio Capital is proud to support businesses and local authorities from across Scotland. Here are a few examples of our partners:

Bute Island
The award-winning, plant-based cheese producer has been crafting products on the Isle of Bute for over 30 years. Operating from a remote island location brings unique logistical challenges, particularly when it comes to managing unavoidable food waste.

Sustainability is a core part of their business, and they are committed to finding responsible, long-term solutions that work both operationally and environmentally.

Bio Capital supports Bute Island Foods by transforming surplus production waste into renewable energy and biofertiliser, helping close the loop between food production and farming.

Albert Bartlett
The 4th generation family-owned business has been running since 1948. They specialise in fresh, chilled and frozen potato products.

They have in-house farmers alongside working with over 100 farming families. Sustainability is in the fabric of their business, as they realise the value it has cost savings, brand loyalty and resilience.

Bio Capital support Albert Bartlett with their sustainability goals and help them turn unavoidable food waste into renewable power.

Falkirk Council
Serving communities across the Central Lowlands, Falkirk Council is focused on building a cleaner, more sustainable future. Managing household food waste efficiently is a key part of that, alongside meeting ambitious carbon reduction targets.

Bio Capital supports Falkirk Council by converting household food waste into renewable energy and biofertiliser, helping reduce emissions while powering homes and supporting local agriculture.
