“…The yield of creole avocado oil obtained through the Soxhlet extraction methodology was 11%. This value is similar to previous reports by Solarte-Toro et al [19]. Avocado oil is rich in oleic, palmitic, linoleic, and palmitoleic acids, while stearic acid is in smaller composition [59].…”

“…However, these processes should involve low technology complexity to avoid incurring complex technification that makes their application impossible in areas with low investment at the industrial level. On the other hand, the high starch content in seeds is also a fraction that can be used for flour production, as reported by Solarte-Toro et al [19]. Regarding proximate analysis and high calorific value, their values agree with other authors and are similar to other agroindustrial wastes used for energy purposes [57].…”

“…However, avocado-oil production is limited in Colombia as most avocados are marketed directly or carried to guacamole production. Similarly, biogas production has been analyzed in biorefinery design since it allows for the use of biomass integrally by producing energy vectors [19]. In this sense, the use and valorization of these residues should be integrated into the avocado value chain, emphasizing the biorefinery concept to improve sustainability and promote the bioeconomic development of the region.…”

This work evaluates the sustainability of small-scale biorefineries as a potential enterprise alternative to be introduced in rural areas based on experimental and simulation data. Four scenarios were evaluated: the first scenario involves the production of guacamole, the second involves the production of animal feed, and the third and fourth scenarios involve the extraction of bioactive compounds and the production of avocado oil or animal feed, respectively. In addition, all scenarios produce biogas and fertilizer. Each of the scenarios were evaluated considering the technical, economic, environmental, and social aspects. As a main result, the first scenario showed the lowest operating and investment costs, as well as the lowest economic profitability (profit margin 35%). On the other hand, the third and fourth scenarios present the highest investment and operating expenses (OpEx USD 6.2 million per year and CapEx USD 1.0 million), but their profit margins are in the 60–70% range. Furthermore, a life-cycle assessment (LCA) was carried out and allows inferring that the transformer link presents the highest environmental impact of the entire value chain and that the carbon footprint for all scenarios ranges between 1.01–2.41 kg CO2 eq per kg avocado. Similarly, the social impact methodology shows that the proposed scenarios do not present any social risk. Thus, the biorefinery for animal feed, bioactive compounds, biogas, and fertilizer was selected as the best option to be implemented in Caldas.

A vocado plantation in Pakistan was started during the year 1955 at Hill Fruit Research Station (HFRS) Murree, Punjab Pakistan. A hectic research was conducted for standardization of production technology and varietal performance comparisons among changing agro climatic conditions. Avocado has wide adaptability range (Gill et al., 2018) for different varieties in temperate and semi temperate areas. Small land holding and limited water resources are the major hurdles for fruit production in targeted areas. It is need of the day to produce the precious fruit 'avocado' for judicial use of land and water resources in combination with agro climatic conditions of submountainous areas. These studies were initiated for Abstract | Avocado is a cash crop for orchard growers and fruit producers. It is famous for its dietary and economic benefits all over the world. Field experiences and literature reveals that avocado varieties behave differently in different locations. These studies were conducted for standardization of promising commercial variety of avocado for cultivation in Punjab. Avocado varieties Murree Gola and Ceylon blue were tested in different locations for their performance. Data was collected for both varieties which shown that Murree Gola flowering is 8-10 days earlier than that of Ceylon blue, while ripening is 6-12 days later in Murree Gola as compared with Ceylon blue. Flowering duration remained 15 days in Murree Gola and 13 days in Ceylon blue. Murree Gola produced heavier fruits (484g) compared to Ceylon Blue (370 g) while Murree Gola produced 150 kg fruit per tree and Ceylon blue produced 120 kg fruit per tree. Murree Gola gave 25% more fruit yield as compared with Ceylon blue which makes it suitable for competing with the climatic conditions of the target areas. Performance comparison of both varieties in same agro-climatic conditions reflects that Murree Gola variety of avocado may give better economical returns to the growers.

“…Colombia se posesiona como un importante productor de aguacate (Persea Americana Mill) en latino América con una oferta diversa, algunas de ellas corresponden a la raza antillana (variedad Lorena y criolla) y guatemalteca (variedad Hass) [1,2]. En el departamento de Bolívar y la región de los Montes de María se estima una producción de 35.000 toneladas anuales de aguacate de variedad criollo-antillano (Laurus persea L) [3]; sin embargo, en los últimos años en la región se ha observado el deterioro y pudrición de las raíces y por consiguiente la muerte de los árboles de aguacate, debido a la presencia de hongos, el mal estado en el que se encuentran las vías, así como la falta de estrategias de comercialización, estandarización y de mejores prácticas productivas en la zona [4].…”

Evaluación ambiental mediante algoritmo de reducción de residuos WAR de la producción de aceite y biochar a partir de aguacate criollo en el Norte de Colombia

En el norte de Colombia la producción y cultivo de aguacate de variedad criollo-antillano (Laurus persea L) se centra en la región de los Montes de María; no obstante, parte importante de esa producción se desecha debido a la falta de infraestructura para la distribución, comercialización y valorización. Por otro lado, el consumo de este genera residuos como la cáscara y la semilla, que pueden ser aprovechables gracias a su composición. Lo anterior, ha motivado la búsqueda de alternativas de valorización de residuos que mejoren la sustentabilidad de la cadena de procesamiento; por lo tanto, resulta necesario evaluar la viabilidad de la producción a gran escala de aceite de aguacate y el aprovechamiento de residuos como la semilla bajo las condiciones del Norte de Colombia. En este trabajo se evaluó desde el punto de vista ambiental el proceso de extracción de aceite y biochar de aguacate (Laurus persea L), a partir de la pulpa y la semilla, respectivamente. La evaluación ambiental se realizó mediante el software WARGUI, el cual tiene en cuenta flujos másicos y propiedades de las sustancias que intervienen en el proceso, evaluándolo bajo 4 categorías atmosféricas y cuatro toxicológicas. Luego de modelar los procesos se obtuvo una producción de aceite de aguacate de 1.000,01 t/año y 504,78 t/año de biochar. Los resultados obtenidos posibilitaron evaluar el comportamiento de los procesos bajo el criterio ambiental, obteniéndose impactos totales de salida de 60 PEI/h, además se observó que los casos 2 y 4 tienen los mayores impactos en las categorías HTPI y TTP. Los impactos de salida totales indican que el proceso es amigable desde el punto de vista ambiental lo que hace atractivo el montaje de una planta de valorización de residuos del cultivo de aguacate al norte de Colombia.
