🔥 Granulés de bois Morbihan - Quality, production and certifications

The wood pellets Morbihan, also known as pellets, are now one of the most efficient and environmentally-friendly fuels on the market. Their popularity is due to their high efficiency, stable combustion and low environmental impact. But to get the most out of them, it's essential to be aware of the quality differences and certifications that guarantee clean, sustainable heating.
🌲 How are wood pellets made?
Pellets are produced from sawmill residues untreated sawdust and wood shavings. These materials are dried, then compacted under high pressure to form small cylinders 6 to 8 mm in diameter and 2 to 3 cm long. The lignin naturally present in the wood is used as a binder: no chemical additives are added.
This manufacturing process produces a moisture content less than 10 % and a density of over 650 kg/m³, guaranteeing even combustion and excellent energy efficiency.

💡 The benefits of wood pellets
- 🔥 High yield up to 95 % for modern devices.
- 🌍 Renewable energy from local wood by-products.
- 💰 Stable prices less sensitive to fluctuations in the energy market.
- 🧹 Cleanliness low ash, no tar, less flue maintenance.
- 📦 Easy storage 15 kg bags or bulk delivery.
🔎 Quality criteria you need to know about
A good wood pellet can be identified by several factors:
- Humidity level ≤ 10 % for clean combustion.
- Density : ≥ 650 kg/m³ (indicates optimum compression).
- Calorific value : ≥ 4.6 kWh/kg.
- Ash content ≤ 0.7 % (generally indicated on the packaging).
- Fine content : < 1 % (dust generated by friction).
These data are governed by European and French standards. Buying uncertified pellets means risking premature clogging, irregular draught and reduced efficiency.
🏷️ Official certifications
The wood pellet certifications guarantee consistent quality, regular checks and product traceability:
- ENplus A1 the European benchmark. Production and transport control. (official ENplus website)
- DINplus German certification, recognised for its rigour. (DIN CERTCO)
- NF Solid biofuels French standard managed by AFNOR and CSTB. (NF Biofuels)
These three labels guarantee a pellet 100 % natural wood, dry, dense and without additives. They also ensure clean transport (no dust contamination or variations in humidity).
🧰 Advice on storage and use
The wood pellets Morbihan can be kept for a very long time, as long as you follow a few simple rules:
- Store in a place dry and ventilated, protected from humidity.
- Avoid any contact with the ground (place the bags on a pallet).
- Never use wet, swollen or powdery granules.
- Regularly check that the tank and feed screw are clean.
Proper storage guarantees easy ignition and stable combustion, without clogging the firebox.
📜 Regulations and the environment
La regulations of 30 March 2022 also regulates the sale of “ready-to-use” wood, including pellets. Sellers must clearly indicate :
- La type of fuel (pellets, logs, densified wood) ;
- Le calorific value ;
- And the humidity level measured.
These provisions aim to reduce fine particle emissions and promote a quality wood energy, in line with the recommendations of the’ADEME.
