TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Method: In providing renewable energy, processing comprises mechanically pressing the Triodia to form it into solid fuel, extracting lignin from the Triodia and forming the lignin into solid fuel, pyrolysis of the Triodia to produce synthesis gas, or pyrolysis of the Triodia to produce bio-oil. Processing includes a sub-step of the Fischer-Tropsh process. Processing comprises the sub-steps of pre-treatment to liberate cellulose and hemicellulose, hydrolysis of cellulose and hemicellulose, fermentation, and distillation to provide ethanol. Pre-treatment comprises steam explosion, mechanical treatment, and chemical treatment. Processing comprises hydrolysis by enzyme catalysis, acid catalysis, heat treatment, or pressure treatment. Processing also comprises the application of 2% sulfuric acid at 20 degrees C for 60 minutes. Hydrolysis is achieved using, approximately, the enzymes 2% cellulase and 4% beta -glucosidase at 50 degrees C, pH 5.0 stirred at 180 revolutions/minute (rpm) for 22 hours. Fermentation is achieved using a recombinant strain of the Zymomonas mobilis ZM4 (pZB5), preferably for 40-60 hours. The energy used in processing the Triodia feedstock is derived at least in part from solar energy. In obtaining volatile fractions from plants of the genus Triodia, heating comprises heating the plant matter to approximately 100 degrees C. The collected volatiles are organic polymers. The collected volatiles are used for the manufacture of incense, aromatic enhancer, furniture polish, biopharmaceuticals, bactericides, fungicides, insecticides, antibiotics, or medicine. The exuded volatiles are allowed to solidify and are collected mechanically or by fractional distillation. In the ethanol production method, fermentation uses microorganisms to ingest the products of gasification and produce ethanol. The microorganism is Clostridium ljungdahlii bacteria or similar bacteria. In harvesting elements, the elements are metals. The methods further comprise removing resin from the Triodia. The energy used in carrying out the steps is derived at least in part from the Triodia. Harvesting Triodia preserves the plants' root system so that the plant regrows. Harvesting Triodia is performed so that firebreaks are produced. Harvesting Triodia is performed according to the expected regrowth rate so that the Triodia can be sustainably harvested.
