Estimating the bioenergy potential of Pinus radiata plantations in Chile
The bioenergy potential for electricity and ethanol production of Pinus radiata D. Don plantations in Chile was modeled, on a regional basis, using radiata pine plantations areas by age class. Wood basic density equations based on age and growing region, wood moisture content variability, and the ef...
