Non Technical Summary
As global energy demand is expected to grow substantially in the next few years, virtually all states in the USA are stepping up their renewable energy agendas at an unprecedented pace. In July 2007, Florida Governor Crist promulgated an executive order requiring utilities in Florida to produce at least 20% of all electricity from renewable sources, including biomass. This initiative has triggered an increased interest in renewable energy from biomass, especially because Florida has a wealth of natural resources. Unfortunately, there is a shortage of studies that analyze the availability of biomass resources and their efficient conversion to renewable energy and biofuels in Florida. The objective of this project is to study if various biomass sources (timber harvesting, wood processing residues, non-merchantable timber, forest understory, agro-forest energy crops, and others) can be utilized more efficiently to produce bio-fuels and bioenergy in Florida. To achieve this objective, a variety of statistical and mathematical methods will be employed to estimate how much biomass can be grown and harvested and how it should be utilized efficiently for bioenergy. The major benefits of this project are: more accurate valuations of biomass sources, especially in the context of an increased biomass market competition; more efficient biomass conversion to bio-fuel and bioenergy; increased commercialization of woody biomass for bioenergy; the development of new forest products markets (i.e. bioenergy markets); and more rigorous development and implementation of state bioenergy policies.

Goals / Objectives
The overall goal of this project is to assess whether various biomass sources (timber harvesting, wood processing residues, non-merchantable timber, forest understory, agro-forest energy crops, and others) can be integrated sustainably into biomass to bioenergy value chains (bio-fuels and bio-power) in Florida. To reach the overall goal, three specific research objectives will be targeted: A. Assessing the availability of biomass for bioenergy and bio-fuels; B. Evaluating technical and economic parameters of converting biomass to pellets; C. Assessing the sustainability of biomass to bioenergy value chains. The deliverables will include: estimates of harvestable understory biomass by forest vegetation type and land ownership class; understory biomass prediction equations; technical and economical feasibility values (yields, costs, revenues) of understory biomass production; growth rates, operational costs (materials, employment, fuel), productivities, energy values, potential biofuel yield and profit values of agro-forest energy crops; technical and economic parameters of converting biomass to pellets; optimal planning and control attributes of multi-feedstock/multi-process operations; valuations of biomass feedstock sources; and sustainability assessments of biomass to bioenergy value chains.
Project Methods
The following methods will be utilized to accomplish the three objectives: 1. Statistical sampling and measurement techniques to assess the availability of biomass for bioenergy; 2. Economic modeling techniques to study the feasibility of various biomass sources (forest understory biomass, agro-forest energy crops, harvesting and processing residues); 3. Optimization techniques to optimally allocate biomass to bioenergy facilities; 4. Life cycle analysis models to assess the sustainability of biomass to bioenergy value chains.

Progress 01/01/09 to 12/31/09

Outputs
OUTPUTS: The following are the outputs of the project according to the research areas addressed: a. Availability of biomass for bio-energy: A forest understory biomass inventory was performed in six counties around Tallahassee, Florida. An forest understory biomass sampling procedure was developed and validated. b. Conversion of biomass to bio-energy: A study regarding the quality management of storage and transportation of wood pellets has been undertaken. Production and material data is collected at a pellet manufacturing facility. Response surface methods are employed to analyze the data. c. Sustainability of biomass for bio-energy: Research activities include life cycle assessments and cost-benefit analyses of bio-energy value-chains, criteria and indicators for biomass harvesting, policies to incentivize the use of forest biomass for bio-energy. PARTICIPANTS: The principal investigator, one technician, and five graduate students worked or are currently working on this project. Partner organizations include: Florida Division of Forestry, Green Circle Bioenergy (A pellet manufacturing facility), Florida's Great North West (a regional development organization), TEAM Santa Rosa (a local development organization). The project has provided tremendous opportunities in training: graduate students in the area of bioenergy from forest biomass, state and federal foresters, state extension faculty, development agencies, bioenergy companies (e.g. wood pellet manufacturers). TARGET AUDIENCES: Nothing significant to report during this reporting period. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

Impacts
The following are the outcomes of the project in each of the three research areas: a. Availability of biomass for bio-energy: Interim results from the forest understory inventory indicate that fairly large quantities of biomass, especially comprised of titi, exist in the study area. b. Conversion of biomass to bio-energy: Analyses generated valuable information about the relationships between pellet storage and transportation variables (e.g. temperature) and production parameters (e.g. drying temperatures, wood species). c. Sustainability of biomass for bio-energy: The life cycle assessments and cost-benefit analyses performed indicated the economic and ecological attributes of converting southern pine biomass into ethanol. In another study, criteria and indicators for sustainable harvesting of woody biomass were developed and proposed for further validation.
