Nordic Biomass has acquired unique experience in relation to the development, construction and servicing of harvesting machinery for willow. A number of harvesters have been developed with financial support from domestic and international development funds. In addition to many years of experience harvesting willow in Denmark, we have also harvested willow and similar energy crops in countries such as Italy and Sweden.

Willow is harvested during the winter season, after defoliation |
| |
Willow can either be harvested as rods or using ‘direct cut and chip’ harvesting. Rod harvesting is ideal when producing cuttings or fences, but is also an option if one wants to dry the willow before it is chipped. Wet woodchips are difficult to store, and when delivering chips outside the harvesting season,
stem harvesting can often be recommended.
One can expect a better pricing on
dry chips than wet chips at the
power plant. |

New test report on chipping of
whole stem harvested willow |
| Nordic
Biomass also offers advice on
chipping of whole stem harvested
willow; and on the 27th of September
2007 invited to a demonstration of
wood chippers working in whole stem
harvested willow. Read the report
here. |

Harvesting technology for willow is under constant development, and despite several available solutions, the existing technology still requires further optimisation. The machinery shown provides an up-to-date picture of current harvesting technology. Nordic Biomass has
some of these harvesters at its disposal,
others are running at colleagues. |

| Claas harvester with a willow header – direct chipping. 2-4 year old willow.
Has been running in
Nordic Biomass, but the
wet woodchips makes it
less ideal for Nordic
