Description

Manufacturing method Cross-reference regarding related applications This application claims priority to Australian provisional patent application No. 2023902101 filed on June 30, 2023, the contents of which are incorporated herein by reference in their entirety. Technology field The present disclosure generally relates to chemical extraction and biomass fuel production methods. One of the most urgent tasks for future generations is to build a sustainable society. The fossil fuels currently used for energy production are finite resources. Therefore, there is a growing need to maximize the production and use of sustainable and renewable energy sources. Biomass fuels are renewable resources and have the advantage of emitting no net CO2 into the atmosphere. However, biomass fuels can cause potential environmental problems by emitting volatile organic compounds (VOCs). Typically, monoterpenes constitute the majority of these emissions during the biomass fuel production process. Therefore, an improved method for sustainable biomass fuel production is required. The present disclosure is based in part on identifying sustainable chemical extraction and biomass fuel production methods. In particular, these methods enable the reduction of waste through the responsible use of biomass and the efficient utilization of energy produced by said methods. The present disclosure provides a method for chemical extraction and biomass fuel production using resinous wood, said method (i) a step of extracting rosin and/or terpene fractions from the resinous wood by treating the resinous wood with an agent that includes, is composed of, or is essentially composed of terpenes; and (ii) includes the step of processing the above-mentioned resinous wood to produce biomass fuel. The period between the step of treating the resinous wood with the reagent and the step of processing the treated resinous wood may be about 15 minutes or less, about 10 minutes or less, or about 5 minutes or less. The step of processing the treated resinous wood may include the step of grinding and/or milling the treated resinous wood to form a particle shape. The particle size of the above-mentioned treated resinous wood may be about 0.1 cm to about 0.6 cm. The grinding step may include dry grinding and/or wet grinding. The step of processing the above-mentioned resinous wood may further include a step of drying the particle form of the above-mentioned resinous wood. The above drying step can reduce the moisture content of the treated resinous wood in the form of particles to less than about 30% by weight, less than about 20% by weight, or less than about 10% by weight. The step of processing the above-mentioned resinous wood may further include a step of compressing the particle shape of the above-mentioned resinous wood to form a compressed shape. The compressed form of the above-mentioned treated resinous wood may be a pellet or briquette, or may include the same. The step of processing the above-mentioned treated resinous wood may further include the step of heat-treating the compressed form of the above-mentioned treated resinous wood at a temperature of about 100°C to about 200°C or about 200°C to about 350°C. The step of processing the above-mentioned treated resinous wood may further include a step of heat-treating the particle form of the above-mentioned treated resinous wood at a temperature of about 100°C to about 200°C or about 200°C to about 350°C. The step of processing the above-mentioned resinous wood may further include a step of compressing the particle shape of the above-mentioned resinous wood to form a compressed shape. The above biomass fuel may be white pellets, white briquettes, torrefied pellets, or torrefied briquettes. The above biomass fuel may be substantially free of pollutants. The step of processing the above-mentioned resinous wood or the processing step of (i) may further include an initial step of at least partially subdividing or desizing the resinous wood as before step (i). The processing step of (i) may further include a step of separating the rosin fraction and the terpene fraction extracted from the resinous wood. The step of processing the above-mentioned resinous wood may further include an initial step of at least partially removing the bark portion and/or root portion from the resinous wood. Energy can be generated for use in one or both of the processing step of (i) and the processing step of (ii) by utilizing at least partially the above bark and/or root parts. The step of processing the above-mentioned resinous wood may further include an initial step of separating the wood raw material into the resinous wood and the remaining wood portion. The above remaining wood portion may not be treated with the above reagent. Suitably, the present method further comprises the step of treating the residual wood portion to extract additional terpene fractions. The treatment step may include heat-treating the residual wood port
