RUF briquettes, also called sawdust briquettes or hardwood wood briquettes, are an overnight success two centuries in the making. Previously, most people in Europe used traditional firewood for wood heating, preferring traditional aesthetics to modern energy density and price-performance.
However, with many people in Europe turning to wood heating as an alternative to expensive gas and electric heating, cost-to-performance is once again the top priority. And this is where briquettes shine. And when it comes to condensed wood fuels, RUF briquettes are by far the most popular option.

What Exactly Are RUF Briquettes?
RUF briquettes are rectangular blocks of highly compressed dry sawdust. The raw material of a quality RUF briquette is 100% natural hardwood sawdust sourced from trusted sawmills. The sawdust is compressed using industrial pressing rods, which creates a product with a far larger energy density than regular firewood.
Why Are Sawdust Briquettes Called RUF Briquettes?
The term RUF briquette comes from the brand name of the most popular manufacturers of these briquetting machines. This machinery was designed to stamp out the RUF brand name on the finished product. Seeing a lot of sawdust briquettes with the RUF logo stamped on them, eventually, people started associating sawdust briquettes with the word RUF.
This being said, most sawdust briquettes are not made using RUF machinery.

Why RUF Briquettes Are Becoming Popular in Europe
Here are just a few reasons why end customers absolutely love hardwood RUF briquettes.
Super Easy, Intuitive, and Convenient to Use
Unlike more advanced wood fuels, which may require a customer to preheat their appliance or know whether their appliance can handle the heat, sawdust briquettes can be used by anyone who has ever used a wood burner. No briquette experience required.
Likewise, RUF briquettes work great in all appliances that are used for wood burning, such as log burners, multifuel stoves, fireplaces, chimineas, pizza ovens, biomass boilers, or even campfires. Their flat shape prevents rolling in open grates, and they fit neatly in backpack stoves for wild-camp cooking.
Wood Fuel Market tip: If your end customer asks what briquette they should try first, we strongly recommend steering them towards beginner-friendly RUF briquettes.
Great Balance of Burn Time and Heat
A single brick can burn for 2 hours in a modern stove and release steady heat throughout the burn.
Ultra-Low Smoke & Creosote
Moisture level below 9% means that Wood Fuel Market sawdust briquettes have virtually smokeless combustion. They release far less particulate matter than firewood, which means they're better for human health, the environment, and the health of wood-burning appliances.
Space-Saving, Easy to Store
Their uniform brick shape allows them to be stacked like LEGOs. It has been calculated by one of our partners that one tonne on a single Euro pallet delivers the heat of 3–4 m³ of split logs. Unopened plastic packs stay dry in garages, sheds, balconies—even damp cellars.
Zero Additives, Reusable Ash
Made from 100 % chemical-free hardwood sawdust, the only residue is mineral ash rich in potassium and calcium. Once cold, sprinkle it on garden beds as a natural fertiliser. If you don't own a garden, you can add a little bit of water to the ash to create an all-natural cleaning paste.
Lighting & Using RUF Briquettes
Here is the best, easiest, and most eco-friendly way to start a fire with RUF briquettes. Depending on what part of the world you live in, it is called either the top-down method or the Swiss method.
Start with two briquettes. Place them on the grate, leaving an approximately 2 cm gap between them for airflow.
Place some kindling on top. Kindling is a heat amplifier that takes heat from a firelighter and magnifies it so that it can easily light any briquette.
Add a natural firelighter. Made from natural wood wool, these are by far the best fire starters on the European market. While kerosene options will do the job, natural firelighters produce a better result. Wood Fuel Market manufactures its own wood wool Natural Firelighters, which are second to none in the entire world.
Open air vents fully. This will allow as much air to reach the fire as possible.
Light the firelighter. It will soon start burning, lighting the kindling, which will light the sawdust briquette. While this is happening, it will gently preheat your stove and flue, leading to lower PM emissions.
Throttle Airflow. Once the bricks glow, adjust vents to the desired setting.
Wood Fuel Market Tip: Mix a couple of kiln-dried birch logs with briquettes to combine lively flame visuals with long heat.

Frequently Asked Questions
Here are the most frequently asked questions about RUF briquettes.
How long does a single RUF briquette burn?
You can expect around 2 hours of ample, cost-efficient heat from your RUF briquettes. This is about twice as long as hardwood firewood.
Where can I use sawdust RUF briquettes?
Sawdust briquettes can be used anywhere you'd use regular wood, from campfires to multi-fuel stoves.
Do RUF briquettes produce much ash?
No. Sawdust briquettes produce very little ash, typically under 0.5 %. This ash is all-natural, so it's safe to use as garden fertiliser or mixed with water as an all-natural cleaning paste.
Can I store briquettes outside?
Yes, if their protective outer packaging is 100% intact and they are under some kind of roof. Rain can seep through any tiny tears in the plastic, so we don't advise telling your clients they can be left outside in the rain.
Are RUF briquettes okay for campfires?
Absolutely. They light easily, don’t spit sap, and burn longer than traditional logs. Perfect for a cooking base or late-night warmth, although (naturally) the ambience is slightly different.
Will RUF briquettes damage my stove or log burner?
No, absolutely not. Sawdust briquettes are safe to use in any wood heating stove.
