Low Temperature Gasification can utilize many different types of biomass and organic waste. The fuel can be difficult biomass with a high proportion of alkaline salts as well as very low grade waste. These can be turned into high value syngas and a compact ash stream that also has good options for utilization.

Partnerships and agreement with different sectors and industries that produce such potential Low Temperature Gasification fuels as a waste product are therefore of great importance in relation to the upcoming DONG Energy operated Low Temperature Gasifier units. Some of these sectors/industries and the corresponding biomass types that can be utilized are illustrated below.

Agriculture Waste wood, Wood chips, Wood pellets, Energy crops, Farming waste, Straw, Manure fibers, Biogas residue fibers
Food Processing Slaughterhouse waste (including fats and bone meal)
Waste Management Paper pulp, Waste water, Sewage sludge, Industrial waste, Household waste

Today's biomass in Denmark
Today, the biomass mostly utilized for energy production in Denmark is straw and wood. Currently these fuels are being co-fired in a 15% ratio in coal fired power plants. Denmark has a large surplus of straw from the farming industry as it is no longer permitted to burn it directly on the fields. The main energy companies in Denmark have therefore entered into agreements where they obligate themselves to co-fire straw. However straw is a difficult fuel as it contains a large quantity of alkaline salts which can partly melt and evaporate when burned at high temperatures. These salts are highly corrosive and will damage coal fired boilers and prevent utilization of coal ash if the ratio of straw becomes too high. Therefore straw is a prime candidate for Low Temperature Gasification.
