Ecological fuels are more important than ever in today's environment and climate change.

Natürlicher Bio Brennstoff Pellets



Fuels from renewable raw materials. Our fuels are produced from chips produced during wood processing. Unlike fossil fuels, pellets and RUF softwood briquettes are wood materials without additives. These are manufactured from wood by-products in accordance with our premium ENERGY WOOD® standards for the fuel and DIY market. Efficient combustion with little residue - your alternative fuels to coal, lignite, gas and oil, while at the same time carbon-neutral combustion, as only as much carbon dioxide is released as the tree was able to absorb during its growth period. Create a living atmosphere with heat from sustainable and renewable raw materials, rettenmeier ENERGY WOOD®.


Our rettenmeier® softwood wood briquettes are made from wood chips and sawdust produced during production. These are compressed at high pressure, whereby the hollowed pulp lignin acts as a natural binder. The use of chemical binders is therefore not necessary. Wood briquettes provide cosy warmth and at the same time are an ecological fuel from renewable resources. In this way, you also contribute to environmental protection at the same time, as the biomass burns carbon-neutral with a low incidence of ash (approx. 0.5%). Other advantages of our rettenmeier® wood briquettes are the long burning time with a calorific value of approx. 19 MJ/kg (approx. 5.3 kWh/kg).


Our wooden briquettes are tested annually in accordance with the requirements of DIN CERTCO. The DIN CERTCO certificate guarantees compliance with the normative requirements for biogenic solid fuels at European level.  All laboratory tests are carried out by an independent testing body on the basis of standardised test methods.

Our rettenmeier® pellets are manufactured from the by-products generated by the woodworking industry, sawdust, planing chips and wood chips. A chemical binder is not necessary. Lignin wood pulp, which is released during production, acts as a natural binder. This means that you have a fuel that is produced exclusively from renewable raw materials with CO2-neutral combustion. Switching to wood pellets is not only worthwhile for the environment, but also for your wallet. There are state subsidies when converting from fossil fuels to biogenic fuels.

Our rettenmeier® pellets are currently manufactured at our site in Ramstein-Miesenbach and our Slovakian site.

These are checked annually according to the requirements of the Control Union. 

The ENplus certificate guarantees the high fuel quality right up to the storage room and monitors the entire supply chain from production to delivery to the customer.

All laboratory tests are carried out by an independent test center on the basis of standardized test methods.

Please note that we are currently unable to supply end customers with pellets in sacks, loose pellets and our briquettes.

We sell our fuels exclusively to strategic partners (B2B / Business to Business). We are not prepared to deliver / collect from end customers.
