Factors Influencing Marketing Supply of Avocado Fruits: A Systematic Literature Review
The global avocado industry is experiencing rapid growth due to increasing demand in both domestic and international markets. However, the efficiency and sustainability of avocado supply chains face numerous challenges. The objective of this paper is to conduct a systematic literature review on the factors influencing the marketing supply of avocado fruits from the years 2015 to 2025. The review was conducted on 10 articles published in various journals, using a qualitative methodology through MS
Valorization of waste biomass via an integrated gasification system for the co-production of dimethyl ether and urea
Energy and chemicals such as urea have a large carbon footprint associated to greenhouse gas emissions and must be developed sustainably for the sake of society. This work presents the simulations of a system to produce Dimethyl Ether (DME) and urea from the air gasification of waste biomass coupled with carbon capture technology. The potential of different waste biomasses (avocado stone, palm tree husk and sugar cane bagasse) in the co-production of DME and urea was assessed in terms of reaction,
Renewable Energies and Biochar: A Green Alternative for Reducing Carbon Footprints Using Tree Species from the Southern Andean Region of Ecuador
The urgent need for sustainable strategies to mitigate climate change has spurred the development of efficient carbon sequestration methods with minimal greenhouse gas emissions, presenting promising opportunities to produce biochar and, with this bioproduct, enhance crop productivity. Therefore, this research aimed to evaluate the carbon footprint produced by the low-temperature slow pyrolysis of biomass obtained from the pruning residues of four tree species present in parks and gardens of the
Biorefinery of avocado seed waste for sustainable production of bioplastics and functionalized silver nanocomposites
This study examines the potential of utilizing avocado seeds (AS) waste for sustainable polyhydroxyalkanoates (PHA) production and green synthesis of silver nanoparticles (AgNPs) in an integrated biorefinery approach. Initially, phytochemical compounds were extracted from AS biomass using solvent extraction. The residual AS biomass underwent hydrolysis through acid pretreatment and was subsequently utilized as a sustainable carbon source for PHA synthesis by Lysinibacillus sp. RGS. Various operational
Changing food waste regimes in Africa’s transition to export-oriented production: the case of Tanzanian avocado
"African nations are increasingly focusing on exporting high-value crops. However, a major challenge exists: high rates of food waste within supply chains. The problem is often seen as a technological issue—a lack of proper infrastructure and coordination creates inefficiencies. This research takes a different perspective, focusing on social relations within the supply chain. It uses the concept of “food waste regimes” to understand the underlying structures, relationships, and systems that
Contribution of food loss to greenhouse gas assessment of high-value agricultural produce: California production, U.S. consumption
Food loss (wasted and spoiled food) increases the burden on resources and environmental impacts throughout the entire food chain. This study describes and deploys a model and identifies data sources for estimation of greenhouse gas (GHG) emissions associated with food loss from farm production, delivery and refrigeration, retail sale, household consumption, and waste management in the United States using four California-grown high-value produce as case studies. The ratios of food wasted to food produced
