The use of energy wood is the backbone of the energy transition, forest hygiene, and a regional energy supply. Clear rules for the quality and allocation of energy wood ranges are required in order to literally avoid sand in the gearbox. Our team trains the industry on the subject, monitors the takeover of energy wood and thoroughly inspects product ranges such as wood chips and shredder wood. We thus also increase acceptance for the most important renewable energy source.
Quality-assured energy wood
The usual assortments of energy wood include wood chips and shredder wood of different quality, but also extend to logs and bark. As an accredited testing body, we test all relevant quality parameters in our biomass laboratory. Based on these analyses, we create accredited test reports on energy wood quality. The common fuel tests include:
- CEN/TS 15370-1, Ash melting behaviour
- EN ISO 18134-2, Water content
- EN ISO 18122, Ash content
- EN ISO 18125, Calorific value
- EN ISO 17828, Bulk density
- EN ISO 16948, Carbon, hydrogen and nitrogen
- EN ISO 17827-1 / -2, Particle size distribution (sieve analysis of wood chips and shredder wood)
- EN ISO 16994, Sulfur and chlorine
- EN ISO 16968, Heavy metals: Arsenic, cadmium, chromium, copper, lead, mercury, nickel, and zinc
We are also recognized as an accredited inspection body for the takeover of energy wood in accordance with the FHP directive and monitor this activity through independent on-site audits.
Quality assessment over and beyond the normative framework
We also offer our customers specialized tests for energy wood that go over and beyond the normative framework. Frequent questions concern smell, microbial infestation and fungal spores, as well as contamination e.g. by road salt. Our service is completed by the “HFA inspected” marking.
Mobile laboratory
If there is any uncertainty about the fuel quality or if unwanted influences are discovered, correct and independent sampling is crucial for laboratory analyses. Remote sampling is particularly flexible here. Using mobile laboratory equipment, our experienced employees also determine chemical parameters on site and take samples from biomass, air, water and soil.

Monitored energy wood reception
Our independent auditors regularly monitor the correct takeover of energy wood in heating and CHP plants, which contributes to the transparency between buyer and seller.
Tested wood fuel quality
We test all wood fuel ranges based on the currently valid test standards. Does the fuel meet expectations? Our laboratory provides for clarity.
