16. Vision of the team
Once the logistics of the material chain will be
optimised, power plants will be very efficient
and clean, especially when designed to use only
wood as their fuel.
fuel
It will also be possible to use the existing methods
in harnessing energy-wood plantations that will
thereby become more productive.
productive
We believe that these are the key elements to take
bio-energy production to a competitive level for the
first time ever.
28-09-2001/ SMa
17. Objectives
to conduct high level research on the development of renewable
and clean bio-energy technology
to model, develop and optimise the complete energy chain
from the forest to the consumers
to develop an energy system producing fuel for the power plant at
a competitive price (<8 EURO/Mwh at the plant)
to develop an energy system that is neutral concerning the CO2
emissions and which keeps other emissions on a lower level
than what the regulations require
to develop machinery and equipment to serve these purposes
to conduct tests to demonstrate the applicability in several
European countries
28-09-2001/ SMa
18. Work division
• The co-ordinator, Timberjack, will develop methods and
machinery for collecting and handling the material.
• UPM-Kymmene as an end-user will test the developed
technology at their plants.
• Shotton Paper and Caledonian Paper company will use and
modify this technology for the UK plants.
• Research involving methods, economics, logistics and
emissions will be conducted by the partners in Austria, (ARCS),
France, (CEMAGREF and AFOCEL) and Italy (IRL).
• CEMAGREF will contribute to collecting equipment design and
IRL will study the possibilities of adapting this technology to
the Southern European conditions. ARCS will make a “LCA”,
Life cycle assessment on the components of the chain.
28-09-2001/ SMa
20. Milestones and expected results
a new method of collecting the small wood and
thinning residuals from forestry operations
a new method of collecting the “normal” logging
residuals left from commercial fellings
fuel price at the power plant < 8 EURO/MWh
neutral CO2 and nutrient balance together with
minimised combustion emissions
at least one working energy chain realised on the
practical level at full industrial scale
28-09-2001/ SMa

27. Logging,
1st step of Bundling Technology
• While working, the harvester
accumulates the slash on piles
(faster to feed into bundling
machine)
• Normally, the goal is to get
slash from 2-3 trees on a pile
• Piles are made by the strip
roads and machines should not
drive over the slash!
• Collecting slash is normally
made only on fertile spruce
clear cut sites
28-09-2001/ SMa
28. Bundling Process
• The bundling machine will produce “slash logs” that are
> 3m long and about 0,6-0,8m in diameter.
diameter
• Bundles are wrapped with strings in every 40 cm.
A bundling
machine
produces about
20-30 bundles
per hour each
weighting avg.
0,4-0.7 tons.

33. Bundles at the Plant
Crushing or chipping of bundles is done at the
power plant, where the “green” chips are often
plant
mixed with other energy material like bark, sawdust
and peat.
28-09-2001/ SMa
34. Bundle Benefits
• Extracted with standard forwarder
• Transported with standard on-road trucks
• Each bundle = 1-1.2 MW of energy
(equals 80-100 L of oil)
• Handled like other assortments
(pulp wood, saw logs…)
• Easy to stock at roadside or at terminal
• Do not start to compost as easily as loose slash pile
• Not so sensitive to moisture (covering not required)
• Wind dried during storage time

40. Scenarios for tomorrow
Northern Europe: Southern Europe:
• big CHP plants like • small and medium
Pietarsaari CHP plants
• industrial networks • municipal networks
connected for steam mainly connected for
& electricity heating
• municipal networks
connected for heating
> economy of scale & > local needs &
superior logistics flexibility
28-09-2001/ SMa
41. Different needs,
different solutions
• The main idea is to develop some general
concepts that we can duplicate and adapt
to very local conditions
• It means that a lot of parameters have to be
considered during the design phase of the
product platforms
• Thanks to our very extended network of
partners (FORENERGY, other projects and
local dealers), we should be able to come up
with optimal solutions: economic,
productive and environmental friendly!
28-09-2001/ SMa
42. Conclusions
• The whole chain working at the moment for UPM-
Kymmene in Pietarsaari is very satisfying
(7 to 9 €/MWh). It consumes less than 3% of the
MWh
total quantity of energy produced.
• Timberjack energy technology (720 & Fiberpac) has
shown itself very well adapted for Scandinavian
conditions. Our goal is now to adapt it to southern
europe conditions taking into account all of its
very particular characteristics (France, Italy,
Spain, Austria, Germany, Eastern Countries…)
