Because GROT belongs to relatively bulky fuels, transport costs are a major proportion of the fuel handling costs.

The GROT market is local.

Payment for the fuel is usually based on the potential amount of energy obtained from the fuel and the moisture content is not important.

As heating plants may have different plant and boiler designs, they have different quality requirements for their fuel and to work properly thay must have clear fuel specifications.

Combustion process in the heating plants is not influenced when moving fuel such as chips with dust to the furnace.

For heating plants, the GROT contamination by mineral soil and rocks can mean a risk for the cost of disposing of the ashes.

The GROT delivery is accepted if it has snow cover exceeding 20 cm.

If the fuel has a low and stable moisture content, it yields a high energy value, it functions properly in different types of heating plants and there is less mold present.

GROT contamination causes a lot of problems and leads to costs for the operator as well as the person contracting the work including downtime costs.

When harvesting GROT on bare ground with frozen soil, there are great demands on the organization.
