TECHNIQUES AND TECHNOLOGY ON SHORT ROTATION COPPICE PRODUCTION Gianni Picchi, Raffaele Spinelli - CNR-IVALSA
Consiglio Nazionale delle Ricerche www.cnr.it www.ivalsa.cnr.it www.biomassaforestale.org Timber and Trees Institute Nearly 20 years of experience on woody energy crops Consultant for Lombardy Region (Italy) on SRC harvest
BIOENERGY IN ITALY - 200 MWht and 400 MWhe; - Demand exceeding 4 millions tons per year; - Booming sector; - Market value of fresh biomass 30-60 /t.
PLANTATIONS FOR BIOMASS - About 5.000 hectars, 3.000 in Lombardy Region; - Different public grants according to region; - Fertile agricultural soils
SPECIALIZED CROP Specific technique and machinery: service companies provide support from the grant demand to the harvest and sold of biomass. 20-25 cm
PLANTATIONS In Italy poplar (Populus spp.) is the only species used: Already well known by farmers; Specialized nursery available; Easy reproduction and hibridization.
DOUBLE ROW short rotation (1 year) 200-280 cm 70-80 cm 45-60 cm Density: 280x75x45 = 12.500 plants/ha
SINGLE ROW short rotation (2 years) 250-300 cm 40-60 cm Density: 300x60 cm = 5,600 plants/ha
SINGLE ROW medium rotation 5 years 300 cm 200 cm Density: 1.100-1600 plants/ha

HARVEST SYSTEMS Many prototypes from all over Europe Different technical solutions Trials in country of origin or in Italy
HARVEST Short rotations: Claas system (HS2-GBE) + 2-3 tractors High productivity Cheaper system High mobility High moisture (60%) Small size of wood chips
HARVEST LONGER ROTATIONS 3 years rotation Stems diameter over 15 cm New crops (harder wood) Krone + Woodcut 1500 John Deere + Biopoplar Substitution of comminuting drum...
HARVEST Medium rotation: forestry systems Integrated production of chips and pulp logs
Claas system costs 220 /hour + 3 tractors for 70 /hora = 430 /hour : 35 t f /hour = 12 /t f Productity depends on many factors: density, planting design, soil type and moisture, stem diameter... Medium rotation: harvest and transport 20 /t f Much room for improvement, flexible system, valuable assortments. SOME ECONOMIC DATA 10-20 /t f to farmers, 35-45 /t f payed by power plants.
FUTURE Optimization of harvest and transportation; New cropping systems (longer rotations); New clones and species. Speciest f /hat s /hat s /ha/y Populus43,719,69,8 Robinia39,024,912,5 Paulownia41,018,09,0 MoisturePrice /t 50%44 40%55 35%61 San Marco plant, 2007
