Can it burn? 

To be able to get optimum efficiency of a bio fuel combustion plant it is important to know the composition of the fuel. It is of decisive importance and is the basis for the choice of the combustion technology.

Dry wood fuel, 8-25 % moisture

 Wood pellets, briquettes
Patent fuel – compressed of dust and chips from the wood processing and furniture industry, produced specially with a view to energy production.  

  Shavings, wood chips, sawdust
These fuels primarily origin from the wood processing and furniture industry.

 Wet wood fuel, 25-55 % moisture

Shavings
Produced specially with a view to energy production (forestry).

Bark, sawdust
Waste from forestry/wood processing industry.

Other bio fuel types, dry, 8-25 % moisture

Straw, husks, grain

Waste types, dry, 8-30 % moisture

Impure wood waste
Crushed, contaminated wood waste from demolishing.

Household waste

Various process related, dry bio fuels/waste types
For instance soy, olive stone, paper waste, cotton, sun flower, non-food fast-growing grain, oat chaff, elephant grass, tobacco waste, potato flour, shea nuts, sun flower husks, fast-growing willow, cacao shells etc.

Waste types, wet, 55 % moisture

Various process-related wet bio fuels/waste types
For instance waste from grapes, instant coffee, rapeseed cakes, paper mass etc.

Enormous heat resources can be hidden in alternative fuel types that may be regarded as waste. The increasing expenses, combined with safe storage and disposal of waste, makes it attractive to think unconventionally – and a challenge that merely is a question of disposal of waste within price-conscious solutions may result in a cost-efficient investment. Companies improve their fuel economy considerably when waste is transformed into process heating.
