This environmentally friendly heating material is made of sawing by-products and requires no use of any binding agents or additives. Due to the high degree of compaction during briquette production, wood as a natural product assumes the combustion characteristics of brown coal but provides the additional benefits of producing very little ash and having low sulphur content.

The CO2 balance is neutral, because the CO2 emitted during combustion equals the amount absorbed through the photosynthesis of a new growing tree.
