Targets for using forest chips set in Finland‟s National Forest Program:

2010: 5 Mm3 ( 10 TWh)

2015: 8 – 12 Mm3 (16–24 TWh)

Forest chip production equipment

demand – Finland 2020

But.......

• Finland is currently using less wood as fuel than planned

• Reason: low price of non-renewable sources

• Finnish wood fuel is 2x more expensive

than coal shipped from Kazakhstan & Australia.

• Peat & coal have very low price of CO2-emission rights.

• Power plants are deliberately distorting competition?

And.......

Finland: Professor says bio-hype steering forestry in wrong direction

Hämeen Sanomat, 23 Sep 2010, p.11:-

According to Professor Matti Kärkkäinen (who is retired from the

University of Joensuu), Finland's forestry is being steered in the wrong

direction by bio-hype. The care of young trees is neglected and

valuable forests are harnessed to produce cheap wood for fuel.

Kärkkäinen wants Finland to utilise the best properties of Nordic

softwood and to grow quality wood. According to Kärkkäinen, burning

wood is favoured through emission trading, energy taxation, and felling

subsidies. Kärkkäinen estimates that also a lot of wood that would be

suitable for commercial use must be burned if the targeted 13.5mn

cubic metres of energy wood is to be achieved.

Supply chains of forest chips

– Finland

Systems where chipping is done at a plant

• at short trucking distances (< 50 km) transport of loose residues is

more competitive than bundling of residues

• centralised chipping suitable for big industrial plants using large

volumes of forest chips

Supply chains of forest chips

– Finland

Systems where chipping is done in the forest / at a landing

• productivity of in-woods chipping depends strongly on forwarding

distance

• if forwarding distance is >250 m, chipping should be done at landing

• suitable when plants can not undertake chipping at the plant

• competitive at large distances (high truck load volume) & where

availability of forest fuel is low

Ponsse Bioenergy

Currently based on

• wheeled Cut-To-Length

• small wood harvesting technology

• slash & stump collecting technology

• high productivity

• mechanised silviculture for young forests

Ponsse Bioenergy harvesting

technology – starting points

• No purpose-built energy wood harvesting equipment required• practical & simple solutions, based on wheeled CTL

• all Ponsse Bioenergy products are „add-ons‟ or attachments

• customers should get additional user-value out of standard harvesting & forwarding equipment

• Integrated harvesting• combined harvesting of energy & industrial wood

• profitable harvesting of energy wood from young forests

• profitable harvesting of pulpwood from first thinning

• Improved utilization-rate of existing harvesting equipment• same machines for tending of young forest & regeneration harvesting of small-diameter trees

• changing business conditions

• additional income for harvesting contractors

Ponsse Bioenergy

• Harvesting – MULTI-STEMMING • efficient technology for harvesting small-diameter trees

• mechanised silviculture for young forest

• Forwarding – VLA & BTS• flexibility in transportation of industrial & energy wood, stumps

• logging residue collection, compression & off-road transport

• Forwarding & trucking – LOAD SCALE • same machines for tending of young forest & regeneration harvesting of small-diameter trees

• new measuring method for timber & energy wood

• Dealer & customer solutions – CHIPPING & BTS• chipping at the stump / on-site or at roadside / landing

Multi-stemming:

PONSSE EH25 & H-series

Solution for productive harvesting of

undelimbed or partially delimbed pulpwood & energy wood:

PONSSE EH25 energy wood harvester head

• no feeding or delimbing required

• base carriers:

S, M & L harvesters, small excavators, forwarders, PONSSE BuffaloDual

PONSSE H53e (H5), H6, H7, H8 harvester heads

• with/without minor accessories

• base carriers:

wheeled & tracked harvesters, PONSSE BuffaloDual (H53e, H5)

• integrated harvesting = pulpwood + energy wood

PONSSE EH25

PONSSE BuffaloDual + EH25

PONSSE BuffaloDual + PONSSE EH25:

• work as real combi machine, harvesting & forwarding at the same time

• trees would be harvested, incl. branches

• depending on tree-height,

trees can be cut in half & loaded as tree-parts

PONSSE BuffaloDual + H53e (H5) & multi-stemming:

• work as „Dual‟, first harvesting & later forwarding

• trees would be felled & processed in bunches

• depending on tree-height, trees can be cut in half,

which will involve delimbing of the first half due to the feeding action

• possibility for so-called integrated harvesting:

harvesting pulpwood & energy wood
