Abstract
Eucalyptus species are native to Australia but grown extensively worldwide as short rotation hardwoods for a variety of products and as ornamentals. We describe their general importance with specific emphasis on existing and emerging markets as energy products and the potential to maximize their productivity as short rotation woody crops. Using experience in Florida USA and similar locations, we document their current energy applications and assess their productivity as short-term and likely long-term energy and related products.
Highlights
Interest in renewable, CO2 neutral, and sulfur-free biomass as a clean source of fuel, chemicals and materials is accelerating [1]
Many products currently derived from petrochemicals can be produced from biomass feedstocks: lubricants, polymers, high matrix composites, textiles, biodegradable plastics, paints, adhesives, thickeners, stabilizers and a range of cellulosics [2]
Samples were run with standard Bruker pulse sequences on a Bruker DPX-250 (62.9 MHz 13C) spectrometer fitted with a quadranuclear 5-mm Z-gradient coil probe
Summary
CO2 neutral, and sulfur-free biomass as a clean source of fuel, chemicals and materials is accelerating [1]. Elite hybrid clones with superior wood quality, rapid growth, and disease resistance are used extensively in tropical and subtropical regions of Brazil, South Africa, Congo, and China. Eucalypts are utilized worldwide for a wide array of products including pulp for high quality paper [14], lumber, plywood, veneer, solid and engineered flooring, fiberboard [19, 20], wood cement composites [21, 22], mine props, poles, firewood, charcoal, essential oils [23,24,25,26], honey, tannin, and landscape mulch [18] as well as for shade, windbreaks, and phytoremediation [17, 27, 28]. The specific objectives were to evaluate and compare the broad suitability of eucalypts and EG, EA, and CT, and estimate their suitability for a range of products
