“…Os ácidos graxos mais comuns são o láurico (C12:0), mirístico (C14:0), palmítico (C16:0), esteárico (C18:0), oleico (C18:1), linoleico (C18:2) e linolênico (C18:3). [15][16] Na atualidade, não existe um exemplo industrial que explique claramente o processo de extração mecânica e refino do óleo de lupino, no entanto, há algumas análises relacionadas com a qualidade desenvolvidas em poucos trabalhos. Portanto, com base em trabalhos prévios com outras oleaginosas e a similaridade com o caso industrial da soja, as diferentes etapas para obter óleo de lupino refinado, considerando a produção posterior de biodiesel, são propostas e mostradas de forma geral na Figura 4.…”

“…[13][14] Dentre as matérias-primas mencionadas, os óleos vegetais (extraídos a partir de diferentes espécies de oleaginosas) têm sido utilizados para a produção de polímeros, resinas para revestimento, tintas, lubrificantes e biodiesel. [15][16][17] No ano de 2019, a produção mundial de óleos vegetais foi de 203,91 milhões de toneladas, sendo que os maiores produtores foram: Indonésia (23,71%), China (13,0%), Malásia (10,16%), a União Europeia (8,9%), Estados Unidos (6,1%), Brasil (4,83%) e Argentina (4,72%). Ademais, estima-se que a obtenção de óleos vegetais para o ano 2020 crescerá 2,2% e calcula-se que a distribuição dessa produção estará composta pelas seguintes oleaginosas: palma (37,9%), soja (27,7%), colza (13,4%), girassol (10,4%), amendoim (3,0%), sementes de algodão (2,5%), coco (1,8%) e outros (3,3%).…”

Biodiesel can be obtained from extracted oil of different oilseeds. The production of this biofuel is carried out by several routes, among them the most common way involves two main stages: the first one related to oil extraction from oilseeds and the second one, includes the conversion of that oil into biodiesel. This review work presents a technical feasibility study about production and use of Andean lupine oil (Lupinis mutabilis) for biodiesel production through methanolic route. Besides, it is described some theoretical physic-chemical properties of Andean lupine biodiesel obtained by mathematical. According to similarity of physic-chemical characteristics between Andean lupine and soy oils, it can be evidenced the possibility of utilization of Andean lupine seeds for bioenergy. The theoretical properties calculated for Andean lupine biodiesel, such as density (20ºC), cetane index, heat power and dynamic viscosity (40ºC) are close to soy biodiesel properties and befitting with the limits stablished by Brazilian laws that regulate the biodiesel industry. Considering the exhibited data in this work, it can be affirmed, from a technical point of view, that Andean lupine can be considered promising for energy market, especially for the Andes ecoregion. However, the suggested processes should be experimentally implemented with the purpose to assess the proposed conditions and thus to compare the theoretical approaches, due to the properties of Andean lupine biodiesel were not found in experimental data of biodiesel production from Andean lupine seeds. O biodiesel pode ser obtido a partir do óleo extraído de diferentes oleaginosas. A produção deste biocombustível é realizada por meio de várias rotas, entre elas a mais comum envolve duas etapas principais: a primeira relacionada com a extração do óleo das sementes e a segunda, com a conversão deste óleo em biodiesel. O presente trabalho de revisão apresenta um estudo de viabilidade técnica de produção e utilização do óleo do lupino (Lupinis mutabilis) para cadeia produtiva de biodiesel por rota metílica, bem como descreve algumas propriedades físico-químicas teóricas do biodiesel de lupino obtidas por meio de modelos. Diante da similitude das características físico-químicas dos óleos de lupino e de soja, evidencia-se a possibilidade de utilização desta oleaginosa para o setor da bioenergia. As propriedades teóricas calculadas, como densidade (20ºC), número de cetano, poder calorífico e viscosidade cinemática (40ºC), para biodiesel de lupino apresentam-se próximas as do biodiesel de soja e condizentes com os limites estabelecidos pelas normas que regulamentam o setor no Brasil. Frente aos dados elucidados neste estudo, pode-se afirmar que do ponto de vista técnico a oleaginosa lupino pode ser considerada promissora para o mercado da energia, notadamente para a ecorregião dos Andes, no entanto os processos sugeridos devem ser implementados experimentalmente com o propósito de avaliar as condições propostas e assim comparar as aproximações teóricas, uma vez que não fo...

“…Recently, a biodegradable spray-on mulch based on sodium alginate was developed as a potential alternative to the thin plastic mulch films currently used in horticulture [9]. Polymeric protein-based biodegradable spray coatings were tested in greenhouse trials [10] and exhibited agronomic performances comparable to commercial low-density polyethylene mulch film, indicating a similar rate of plant growth and dry matter accumulation and a complete biodegradation (<5% residues after 2 months).…”

Initial Experimental Experience with a Sprayable Biodegradable Polymer Membrane (SBPM) Technology in Cotton

et al. 2020

Preformed biodegradable and next generation sprayable biodegradable polymer membrane (SBPM) formulations, which biodegrade to non-harmful products (water, carbon dioxide and microbial biomass), have been introduced as an alternative to plastic mulch films in order to mitigate plastic pollution of the environment. In this preliminary field study on cotton (Gossypium hirsutum L.), a novel SBPM technology was compared to preformed slotted oxo-degradable plastic (ODP) mulch film and no mulch control (CON) in terms of yield, crop water productivity (CWP), and soil temperature. The first results showed higher CWP and crop yield, and increased soil water content under the SBPM cover. This study indicates that SBPM technology could perform at similar level as ODP or comparable films under field conditions and, at the same time, provide environmentally sustainable agricultural cropping practices. Additionally, the fully treated, non-replicated SBPM plot had a wetter soil profile throughout the entire crop season. This innovative technology has shown a high potential even at this early stage of development, indicating that advances in formulation and further testing can lead to significant improvements and thus increased use in crop production systems.

“…The silane‐based treatments used in previous work result in extreme hydrophobicity (Chan & Lourenço, 2016) and would be of limited utility for large‐scale agriculture; polymerized plant oils (de Espinosa & Meier, 2011) have potential as a low‐cost and renewable alternative. Preliminary laboratory tests have shown it possible to create a loose hydrophobic mulch by coating agricultural waste products with fast‐drying linseed oil that polymerizes at room temperature (Vaicekauskaite et al., 2019). The polymerization of slow‐drying vegetable oils (e.g., soybean [ Glycine max (L.) Merr.])…”

Mulching with polyethylene film is the conventional approach to decrease evaporative water loss from agricultural soils, but it is not environmentally sustainable. In this study, a laboratory experiment was conducted to test the potential utility of partially polymerized soybean oil (PSO) coated sands as a surface treatment to reduce bare soil evaporation. Evaporation was tracked for 23.8 d from saturated sand columns treated with a surface layer (1 or 2 cm) of either coated medium sand (MS-PSO) or coated coarse sand (CS-PSO). The water drop penetration time (WDPT) was used to assess the hydrophobicity of fresh PSO-coated sands; the saturated hydraulic conductivity (K s) and particle density (ρ s) were measured as well. The WDPT was also tested on MS-PSO and CS-PSO samples aged in four separate environmental conditions for 20-21 d. Both PSO-coated sands were mildly hydrophobic, and the surface treatment layers reduced evaporative loss by 83-96% over bare soil, which is similar to previous work using extremely hydrophobic chemically treated sands. Freshly coated MS-PSO had a higher WDPT score and lower K s than CS-PSO. After the environmental aging tests, the MS-PSO and CS-PSO samples remained mildly hydrophobic. Notably, CS-PSO had a low initial WDPT (∼1.09 to ∼2.58 s) and a high K s (2.66 × 10 −1 cm s −1), suggesting coarse PSO-coated sands will permit infiltration. Given these findings, PSO-coated sand has the potential to be developed into a sustainable alternative to polyethylene film mulch.
