“…Pennisetum purpureum or elephant grass (Peçanha et al, 2019) (Macêdo et al, 2019), is a tropical climate plant species that has a C4-type metabolism (high photosynthetic rate), standing out among other biomasses, its productivity reaches 45 tons of dry mass per hectare per year (ton DM ha -1 yr -1 ), while sugarcane and corn produce approximately 21 ton ha -1 (sugar and bagasse) and 13 ton ha -1 (grains and stoves), respectively (Jennewein et al, 2017).…”

In order to increase its efficiency in the bioethanol production process, the biomass needs to undergo a pre-treatment, which can greatly burden the biochemical process. For this reason, industries are using some mathematical models that optimize internal processes, such as fuzzylogic, as it uses linguistic values instead of numerical ones, which provides the addition of uncertainty to the problem, better understanding by non-specialists, answers faster and lower computational costs. Given the above, the objective of this work was to optimize the independent variables in the alkaline pre-treatment with NaOH in elephant grass to quantify the percentage of cellulose and lignin using fuzzylogic. For the input values of this system, the variables of NaOH concentration and temperature were used, and for the outputs, the percentages of cellulose and lignin. The interpretation of the use of fuzzy logic in this experiment using real laboratory data, managed to optimize the best concentration of NaOH and the best temperature in an alkaline pre-treatment with NaOH to quantify cellulose and lignin, concentrations between 1.15 to 2 .15%, with temperatures between 100.0 to 102.5°C for the highest exposure of cellulose and 0.0 to 1.15% for concentrations and temperatures between 85.5 to 91.5°C for delignification. It was observed that the concentration significantly affects the result of greater exposure of cellulose and biomass delignification in the evaluated parameters, so the mathematical model proved to be efficient for this evaluation.

“…Other tall wetland graminoids that can replace fossil fuels under sustainable cultivation conditions are Typha latifolia, T. angustifolia and Arundo donax. These species have moderate to high flooding tolerance with sustained productivity in waterlogged soils [21][22][23], spread clonally by belowground shoots and have high biomass productivity. All three species are perennial, with aboveground shoots dying off in autumn but belowground shoots and roots that overwinter and produce new shoots the following growing season.…”

Biomethane Yield from Different European Phragmites australis Genotypes, Compared with Other Herbaceous Wetland Species Grown at Different Fertilization Regimes

Phragmites australis, Typha latifolia, T. angustifolia and Arundo donax are tall wetland graminoids with the potential to replace fossil fuels under sustainable cultivation conditions. We investigated the biomethane (CH4) production of these four species, including four different genotypes of P. australis, which represent the high intraspecific diversity of European reed. All plants were grown under three different macronutrient supplies (no nutrients added, an equivalent of 75 kg N ha−1 year−1 added and an equivalent of 500 kg N ha−1 year−1 added). Biomethane production was measured in four independent batch digestion tests. Across all experiments, fertilization regime had little effect on CH4 yield, which was on average 222 ± 31 L kg−1 volatile solids (VS). The lowest yield was produced by T. angustifolia (140 L kgVS−1) receiving no nutrients, while the highest yield was produced by A. donax (305 L kgVS−1) in the highest nutrient treatment. The intraspecific diversity of P. australis did not affect biomethane production. All P. australis genotypes produced on average 226 ± 19 L CH4 kgVS−1, which, although high, was still lower than conventional biogas species. The biomass production of P. australis was less increased by fertilization than that of Typha sp. and A. donax, but all species had similar biomass without fertilization.
