RUF briquette specifications vary, but generally feature a moisture content under 10, ash content below 1, and a high calorific value around 4.5–5.2 kWh/kg, with dimensions varying from approx. 150x60x100 mm to 155x95x65 mm, depending on the manufacturer and press. They are made from 100 natural wood, often pine, oak, or birch, and are packaged in 10 kg bundles for storage and transport.
Key Specifications
Material: 100 natural wood sawdust (e.g., oak, pine, birch, fir).
Moisture Content: Typically less than 10 or 8.
Ash Content: Generally under 1, with some suppliers listing below 0.5 or 0.54.
Calorific Value: Around 4.5 to 5.2 kWh/kg (16.2 to 18.7 MJ/kg).
Density: Approximately 0.9 to 1.0 t/m³ or kg/dm³.
Sulfur Content: Low, often under 0.05.
Dimensions: Varies, but common sizes include 150 mm (length) x 60 mm (width) x 100 mm (height), 150 mm x 95 mm x 65 mm, or 155 mm x 95 mm x 65 mm.
Packaging: Usually sold in 10 kg bundles, with 12 briquettes per bag.
Storage: Must be stored in a dry place to maintain quality.
What They Are
RUF briquettes are dense, rectangular fuel logs made from compressed wood dust, produced using the RUF briquetting press. They are a sustainable and efficient fuel source, formed without the use of binding agents.
How They Are Made
Wood sawdust or chips are fed into a RUF press, which uses high pressure to compress the material into briquettes. The pressure is high enough to generate heat, binding the sawdust together without the need for glue.
How to Find the Right Specifications
Check the supplier: Specifications can vary between manufacturers.
Look for certificates: Some suppliers provide certificates of analysis to verify briquette quality, such as ash content.

Use
Eco-briquettes can be burned in all solid fuel heaters using coal or firewood, in common fireplaces and stoves, boilers, open fireplaces, etc.
They are convenient for transportation and storage – they occupy much less storage space due to their higher density;
They don’t pollute the storage premises;
They are not attacked by rodents;
Low ash content, which facilitates cleaning of stoves, fireplaces and boilers;
Lower moisture and better burning than wood;
Higher energy conversion efficiency compared to wood;
Ecology
briquettes are produced only from sunflower husk, technological waste in the production of oil or peeled sunflower. They are great eco-friendly fuel and could replace fuels such as coal, wood, coal dust briquettes, fuel oil, etc. They are obtained by pressing at high pressure and temperature without the addition of binders. The lignin naturally present in the sunflower husk melts at a temperature above 100 ° C and acquires the properties of a binding cementing substance.
Stability
Sunflower husk briquettes do not contain harmful emissions and resins. Their good quality is determined by their high calorific value, low content of emissions that are negligible in the atmosphere. One ton of sunflower husk briquettes in calorific value is equivalent to 1.90 tons (5-6 cubic meters) firewood, 1.4 tons of brown coal, 2.5 tons of coal dust briquettes or 500L petroleum.

Premium Nestro briquettes are made in Poland from fine spruce and birch sawdust. All sawdust comes from a company producing furniture. Briquettes are highly compressed, so are very dense and dust-free which gives them a good long glow time. These briquettes are suitable for all fires, with no need for separate kindling. They hold their shape and are versatile enough to start the fire with and to use for long main burning.
