What are straw pellets, exactly?
Straw pellets made from corn stalks, wheat straw, and rice straw can be used as fuel pellets, animal bedding, and animal feed and are produced with less ash content and high calorific value. The pelleting process compresses raw straw under high pressure and heat, binding the fibres without any chemical additives. The result is a compact, dense pellet that is far easier to store and transport than loose straw.
Pelleting of straw increases bulk density, improving storability and reducing transportation costs. That efficiency benefit alone makes bulk straw pellets far more practical for large-scale buyers, including equestrian yards, poultry farms, and biomass energy operators.

Why buy straw pellets for horse bedding in the UK?
Horse bedding is where straw pellets have built their strongest reputation in the UK market, and for good reason.
Many horse owners report that stables bedded with straw pellets are noticeably cleaner and have significantly reduced ammonia odour. Straw pellets are especially popular for horses with allergies or respiratory sensitivities.
The pellets are highly absorbent and can absorb four times their weight in liquid. They expand to about seven times their size, so they are compacted, meaning a 15 kg bag expands with moisture and breaks down underfoot.
With the ability to soak over 600% of their own weight within 15 minutes, straw pellets absorb larger amounts of water than any other form of horse bedding, including wood pellets.
This absorbency directly translates into practical, financial, and welfare benefits for horse owners:
- Faster, easier mucking out
- Smaller muck heaps
- Significantly reduced ammonia levels in the stable
- Healthier respiratory environment for horses and handlers
- Fully compostable waste that breaks down into rich fertiliser
The bed is firm but cushioned, supporting hooves while padding hocks and joints, and it holds enough moisture that hooves do not dry out the way they can on very absorbent wood bedding. It is dust extracted for respiratory health, fully compostable, and breaks down quickly into nutrient-rich manure.

How do straw pellets work as biomass fuel?
Straw pellets as fuels are usually burnt in pellet boilers, pellet stoves, and other pellet appliances at the household level. Large-scale straw pellets are co-fired with traditional fuels such as coal, oil, and others at large-scale boilers, power plants, or factories.
Straw pellets usually have a lower calorific value than wood pellets but still deliver usable energy, typically around 14 to 18 MJ/kg depending on crop type. According to a 2022 peer-reviewed study published in PMC, the calorific value of wheat straw pellets reaches approximately 22.19 MJ/kg under specific processing conditions, confirming their viability as a serious fuel source.
The energy contained in straw is highly concentrated, giving a fuel with very good energy qualities as well as minimal amounts of ash. The ash from burning pellets can be used as a mineral fertiliser because of its high content of elements vital for plant growth.
Pellet fuel made from crop straw is burnt in a special gasification boiler with a thermal efficiency of 81%. The emission of CO₂ and SO₂ is near zero. It can replace non-renewable fuels such as coal and oil and reduce the impact of waste on the environment.
From a regulatory standpoint, the European Union’s Renewable Energy Directive mandates that 42.5% of energy consumption derive from renewable sources by 2030, creating regulatory tailwinds for biomass fuel applications. Straw pellets sit squarely within this renewable energy framework, making them an increasingly strategic purchase for European industrial and residential buyers.
Demand is likely to rise as biomass pellets support decarbonisation across heating and power systems. Industrial users are expected to prefer pellets that offer stable calorific value and lower moisture content.
Where do straw pellets fit into the European energy market?
Europe remains the leading region for straw pellets, supported by strong policy incentives and advanced infrastructure, while Asia Pacific and North America show rapid expansion due to growing agricultural output and new bioenergy initiatives.
Individual household pellet stove systems burn 3 to 6 tonnes annually at heating costs approximately 40% below fossil fuel alternatives. For European buyers looking to reduce energy costs while meeting sustainability commitments, bulk straw pellets delivered by truck or tonne offer a clear and measurable advantage.
Wheat straw, barley straw, and oat straw have historically been burnt or left in fields, but modern industrial processing now converts these materials into engineered fuel products and animal bedding solutions.
We supply straw pellets in bulk to clients across Europe. Visit our buying wood pellets in bulk guide for detailed information on volume ordering, or browse our shop for current product listings.
Which animals benefit from straw pellet bedding?
Straw pellets can be used as animal bedding, animal feed, and heating fuel for household and industrial use. Beyond horses, the range of animals that benefit from straw pellet bedding is broader than most buyers realise:
- Horses and ponies, including those with laminitis or respiratory conditions
- Cattle and sheep, where ammonia control supports respiratory health
- Poultry, where poultry operations raising 26 billion birds annually represent the largest agricultural bedding market, with broiler facilities and layer operations increasingly standardising on pelleted systems.
- Pigs, particularly farrowing houses, where dry, clean flooring is critical
- Cats and small domestic pets, where the natural absorbency controls odour without chemical additives
- Rabbits and guinea pigs, where dust-free bedding protects sensitive respiratory systems
Livestock operations managing large numbers of cattle, swine, and poultry require bedding material, and straw pellets offer superior moisture management and ammonia reduction compared to traditional shavings.
How to store straw pellets correctly
Proper storage protects your investment and maintains pellet quality. Key points include:
- Store in a dry, covered location away from direct moisture
- Keep bags off the ground on pallets or wooden boards to prevent damp absorption
- Avoid direct sunlight, which can degrade the pellet structure over time
- For bulk deliveries by truck, ensure a sheltered storage area is available before delivery

What are straw pellets used for?
Straw pellets are used for horse bedding, livestock bedding, biomass heating fuel, animal feed, garden mulch, and small pet litter across residential, agricultural, and industrial settings.
Are straw pellets better than wood pellets for horse bedding?
Straw pellets do not need watering like the wood variety, are ultra-absorbent at up to 400% by weight and twice as effective as wood pellets, are softer, non-slip, and healthier, and bind the smell of ammonia far better.
How many straw pellets do I need for a horse stable?
The quantity depends on stable size and the horse’s habits, but most UK equestrian sources suggest starting with 3 to 5 bags (15 kg each) for initial bed setup, with ongoing top-ups of 1 to 2 bags weekly. Buying in bulk by ton or truck, as we offer at Cambridgeshire Straw Pellets Limited, significantly reduces the cost per bag.
Can straw pellets be used as fuel in a standard pellet stove?
Straw pellets are mostly used for co-firing in industrial boilers, rural heating, or small-scale power generation. For domestic pellet stoves, check your appliance manufacturer’s guidelines, as some stoves require pellets to meet specific ash content and diameter standards.
Are straw pellets environmentally friendly?
Yes. The market benefits from increased collaboration across the value chain, emerging applications in animal bedding and bioplastics, and continued research into enhancing pellet durability and sustainability. Straw pellets are fully biodegradable, carbon-neutral when burned, and the spent bedding composts into agricultural fertiliser, meaning nothing goes to waste.
