“…Enquanto que o Orbignya phalerata quando utilizando etanol como solvente, apresentou o teor de lipídeos de 45% (Pinto et al 2012). Atribui-se este valor ao tipo do solvente utilizado (polar ) (Martins et al 2013) e aos cuidados de pré-análise do referido autor, uma vez que o mesmo relata que a umidade da oleaginosa pode influenciar na extração do lipídeo.…”

RESUMOO plano de utilização sustentável de Produtos Florestais, especialmente as espécies oleaginosas nativas tem como função a manutenção da floresta, a preservação do meio ambiente e a geração de renda em comunidades rurais. Neste sentido, este trabalho teve como objetivo avaliar a potencialidade de produção de biodiesel a partir de espécies oleaginosas nativas do estado de Rondônia. Para a identificação das espécies oleaginosas foram selecionadas cinco unidades amostrais em áreas com mata primária com o auxílio do método da Área Fixa. A extração do óleo das espécies oleaginosas foi realizada e aquelas com maior teor de lipídeos foram usadas para a produção de biodiesel. Os resultados mostraram que as espécies andiroba (Carapa guianensis), babaçu (Orbignya phalerata), castanha do Brasil (Bertholletia excelsa), tucumã-do-Amazonas (Astrocaryum tucuma) possuem potencial de produção de biodiesel. Especialmente o tucumã-do-Amazonas, por seu alto teor de lipídios (21,5%) e a qualidade do biodiesel produzido. Além disso, já havia um comércio para esta oleaginosa na região. Entretanto, torna-se imprescindível o estudo da cadeia produtiva destas espécies como estratégia para minimização na perda da cobertura vegetal nativa e na manutenção da função ambiental das áreas a serem exploradas.

Potential of biodiesel production with oil seed native species from Rondônia, Brazil ABSTRACTThe plan for sustainable use of Forest Products, especially the native oil seed species, has the function of maintaining the forest, environmental conservation and income production in rural communities. Thus, this paper aimed to evaluate the potential production of biodiesel from native oil seed species. For the identification, five oil seed species sampling units were selected in areas with primary forest using the Fixed Area method. The extraction of oil from oil seed species was carried out and those with higher levels of lipids were used for the production of biodiesel. The results showed that species andiroba (Carapa guianensis), babassu (Orbignya phalerata), Brasil nut (Bertholletia excelsa), "tucumã-do-Amazonas" (Astrocaryum tucuma) all of them have potential for biodiesel production. Especially "tucumã-do-Amazonas" for its high level of lipids (21.5%) and the quality of the produced biodiesel. In addition, there was already a trade for this oil seed in the region. However, it becomes essential to study the productive chain of these species as a strategy to minimize the loss of native vegetation and maintaining the environmental function of the areas to be explored.

“…During the processing, the mesocarp is removed and the oil is extracted through pressure, generating a protein-rich cake that can be used for bioethanol production [110,8]. The oils extracted from the mesocarp and endosperm are suitable for biodiesel production [111], for uses in chemical and food industries [93][94][95], and applications in the cosmetics and pharmaceutical industry [112]. From the endocarp, a solid biofuel (biochar) can be obtained for thermal energy generation [2,8] and also used as biosorbent, with possibilities for environmental purposes such as water/wastewater treatment/remediation [102][103][104][105][106][107][108][109]37].…”

Macaúba is a tropical palm native in South and Central America, and its fruits present a high-quality oil for biodiesel production. Notwithstanding, macaúba's wastes and by-products are not usually repurposed as energy sources. This study shows a bibliometric analysis to assess macaúba's current applications and to investigate other energy recovery routes for its by-products. All the investigations focused on information about the main research fields related to macaúba. The study showed that only 397 articles and reviews were published from 1900 until 2021, and Brazil is the leading publisher. Although oleic and protein macaúba's by-products are applied as animal feed, some conversion routes related to the lignocellulosic contents, present in non-edible parts, were identified thermal conversion, combustion, gasification, pyrolysis, biochemical conversion, fermentation, esterification, and anaerobic digestion.From the agricultural perspective, plant characterization, germination, embryogenesis, and seed development were also found. From the bibliometric study, the different potential applications of macaúba for energy, pharmaceutical, and food purposes were listed to support the identification of a knowledge gap on its by-products revaluation.

“…These legal requirements have undoubtedly contributed to reduce petroleum consumption and the Brazilian share on greenhouse gas emissions (Pinto et al, 2012;Vieira et al, 2021), but at the same time, have boosted the generation of glycerol, a by-product that represents about 10% in mass of the produced biodiesel.…”

Anaerobic digestion can be a viable alternative for the destination of effluents from stabilization ponds rich in naturally produced microalgae, without the need for concentration processes, however, there are challenges related to the rigid cell wall of microalgae and the low carbon content in its composition, to be overcome. To improve these parameters, this study comparatively evaluated hydrolytic pretreatments in microalgae from effluents from stabilization ponds, aiming to hydrolyze the cell wall of these microorganisms, for co-digestion with residual glycerol from biodiesel. In this case, glycerol is a by-product with limited applicability, acting in this scenario as a carbon supplier, improving the C/N ratio, microalgae biodegradation and biomethane production. Effluents with microalgae submitted to thermal and ultrasonic hydrolysis (for 30 and 90 minutes) were tested to assess their potential in the production of methane-rich biogas, monitored by gauge measurements and gas chromatography, respectively, in co-digestion with residual glycerol from biodiesel. The heat treatment for 30 minutes showed more satisfactory results and was replicated in a benchtop anaerobic reactor (R2), in parallel with a reactor operating untreated microalgae (R1), in a continuous feed system. The effects of pretreatment and COD/N ratio were evaluated on organic matter removal and biomethane production. R2 showed the most satisfactory effect on COD removal, resulting in up to 90% COD removed, with a theoretical biogas production of 0.52 L g-1 COD removed. As for the methane content contained in biogas, R1 reached percentages of up to 84% against 73% in R2.
