Life Cycle and Cost Benefit Analyses of Ethanol Production from Slash Pine (pinus Elliottii) Plantations
نویسنده
چکیده
This paper considers potential cellulosic ethanol production from Southern slash pine (Pinus elliottii) plantations. The net energy balance (NEB), emissions and associated environmental impacts, unit cost of ethanol production, and associated changes to forest land values are calculated and preliminary results are given. The NEB is found to be positive at 2.2, meaning that for every unit of energy input to the system, 2.2 units of energy are obtained through the ethanol produced. Associated impacts are significant, but less so than the corn starch to ethanol production process. The unit cost of ethanol produced in the manner considered, a two stage dilute sulfuric acid hydrolysis, was found to be $0.44 per liter, greater than the current cost of production of ethanol from corn. The forestland values, demonstrated to increase under various degrees of ethanol production, were found to be negative under the maximum ethanol production scenario.

Study on Slash Pine (Pinus elliottii) as a Short Rotation Forestry in the North of Iran
Forests of Iran located on the Southern border of the Caspian Sea cover 1.9 million hectares. The Caspian forests are divided into four separate forestry areas. One of these being Guilan influx area with total area of 565000 hectares. About 30 to 40 percent of Guilan province forests are suitable to short rotation forestry for afforestation. Slash pine (Pinus elliottii) is one of the main exo...
متن کاملA Modified Stand Table Projection Growth Model for Unmanaged Loblolly and Slash Pine Plantations in East Texas
Four methodologies to project future trees per acre by diameter class were compared to develop a new modified stand table projection growth model for unmanaged loblolly pine (Pinus taeda L.) and slash pine (Pinus elliottii Engelm.) plantations in East Texas. The new models were fit to 92,882 observations from 153 permanent plots located in loblolly pine plantations and 33,792 observations from ...
متن کاملConverting Even-Aged Plantations to Uneven-Aged Stand Conditions: A Simulation Analysis of Silvicultural Regimes with Slash Pine (Pinus elliottii Engelm.)
There has been increasing interest in managing forest stands as uneven-aged structures to promote sustainable harvests as well as maintain ecosystem services. This study provides a framework for simulating conversion of mature even-aged stands to uneven-aged slash pine (Pinus elliottii Engelm.) stands using the USDA Forest Vegetation Simulator (FVS) model. A total of 73 scenarios, representing ...
متن کاملTop Grafting Longleaf x Slash Pine F1 Hybrids on Mature Longleaf and Slash Pine Interstocks
-Top grafting is used to accelerate the breeding cycle of loblolly pine (Pinus taeda L). Scions, collected from seedlings as young as 1 year from seed, are grafted onto mature interstocks of the same or a related species. Male and female strobili production often begins 1 or 2 years after grafting, thus potentially decreasing the generation time by several years over conventional accelerated br...
متن کاملAn Annual Tree Survival and Diameter Growth Model for Loblolly and Slash Pine Plantations in East Texas
An annual growth model that predicts individual tree survival and diameter growth was developed for loblolly pine (Pinus taeda) and slash pine (Pinus elliottii) trees in East Texas as a function of individual-tree diameter, plantation age, basal area per acre, dominant height, quadratic mean diameter, and presence of fusiform rust (Cronartium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme)....
