Turn wood chips, dust, and industrial waste into resources: all materials suitable for briquetting
Three series of machines for all materials, ranging from individual units to automated and centralized systems
Compact your wood chips, dust, and industrial waste into briquettes to create resources
Every day, Italian manufacturing companies produce tons of shavings, dust, and waste: wood, metal, textiles, biomass, paper, plastic, and more. Managing this waste costs time, space, and money.
COMAFER briquetting machines—manufactured in Brescia since 1975, with over 30,000 units sold in 70 countries—transform wood chips, sawdust, and waste into compact, easy-to-handle, and reusable briquettes.
The result? Lower costs, more order, new value.
Why turn your wood shavings, sawdust, and scrap into briquettes?
Regardless of the material processed, briquetting offers concrete and measurable advantages:
-90% Volume
Drastic reduction in the volume of chips, dust, and scrap: less warehouse space, fewer containers, and fewer trips to the collection center.
-70% Recycling Costs
Briquettes cost less to dispose of and are worth more at collection centers compared to loose chips.
-80% Handling
Operators spend less time collecting chips, dust, and scrap, thanks to easy handling with a forklift.
Sustainability
Fewer containers, fewer trips, fewer emissions. Briquettes are part of the circular economy and improve the company’s ESG profile, increasingly relevant for customers and investors.
Choose your waste material
COMAFER handles over 100 types of materials. Select the category that matches your chips, dust, or scrap to find the best solution.
Do you have a material not listed? COMAFER can test it in its Research & Development department in Brescia. Contact us to send a test sample.

Wood and derivatives
Chips, sawdust, dust, packaging, carpentry and woodworking waste.

Metal
Chips and scraps of aluminum, steel, cast iron, copper, brass, titanium, and other ferrous and non-ferrous metals.

Textile
Remnants, textile fibers, wool, cotton, absorbent materials, shredded fabric.

Biomass
Agro-industrial residues: pomace, rice husks, chaff, hay, fodder, shells, food waste.

Paper and cardboard
Ground paper, cardboard, filter waste, withdrawn banknotes, tissue paper.

Plastic
Polyethylene, polypropylene, PET, EPS polystyrene, polyurethane, PMMA, and other industrial plastics.

Other
Ground cables, leather, hide, feathers
Material moisture: the key parameter
To obtain optimal quality briquettes, the processed material must have a moisture content between 8% and 17%. Materials with moisture outside this range may require pre-treatment or special configurations.
If in doubt, our R&D department can perform briquetting tests on your specific material before purchase.
How does a COMAFER briquetting machine work?
COMAFER briquetting machines are hydraulic machines that compress wood chips, sawdust, and industrial waste at extremely high pressure to form compact cylindrical briquettes. The cycle is fully automatic:
- The material is loaded into the hopper (manually, from silos, or via a vacuum system)
- A paddle agitator feeds the material into a sliding drawer, operated by a hydraulic cylinder, and transfers it to the compaction chamber
- The hydraulic compaction cylinder compresses the material in the compaction chamber, forming a cylindrical briquette
- A hydraulic system controls the ejection of the briquette into the container or onto the discharge conveyor belt
The entire process is controlled by a PLC and an HMI (depending on the model).
FAQ
Frequently asked questions about briquetting
What is a briquetting machine and how does it work?
A briquetting machine is a hydraulic machine that compresses wood chips, dust, and industrial waste at very high pressure to form cylindrical briquettes. The process is automatic: the material is loaded into the hopper, metered, compressed, and the briquette is automatically ejected.
What materials can be briquetted?
COMAFER has tested over 100 types of materials: wood, metals (ferrous and non-ferrous), textiles, biomass, paper, cardboard, plastics, and many others. If you have an unconventional material, you can send a sample to our R&D department for a free test.
How much volume is saved with briquetting?
The reduction in volume depends on the material, but on average, compaction reaches up to 90% compared to loose wood chips. This means that 10 containers of loose wood chips become 1 container of briquettes.
Can I profit from briquettes?
Yes. Briquettes of wood, paper, and natural materials can be used as fuel for boilers and fireplaces (average calorific value 4,000-4,500 kcal/kg, vs. 2,000-2,300 kcal/kg for firewood). Metal briquettes have a higher commercial value than loose chips because they guarantee a melting yield exceeding 90%.
What is the difference between Dinamic, Special, and Metalpress Series?
The Dinamic Series is designed for wood, paper, biomass, plastic, and similar materials. The Special Series is optimized for textile waste and very bulky, lightweight materials, thanks to the vertical pneumatic cylinder that improves chamber filling. The Metalpress Series is designed for metal chips and the recovery of coolant.
