Valorization of waste biomass via an integrated gasification system for the co-production of dimethyl ether and urea

Authors: Buentello-Montoya, D.A.; Sepúlveda-Montufar, L.; Pulido-Moreno, D.O.

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

Authors: Cobos-Torres, J.-C.; Idrovo-Ortiz, L.-H.; Cobos-Mora, S.L.; Santillan, V

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

Climate change and agricultural workers in the Michoacán avocado industry: Opportunities and trade-offs in coupling plant and human health for sustainability

Authors: Dhesi, SZ., Jolly, AR., Muñoz, R., Olson, V., Huxman, TE.

The rapidly expanding demand for avocado production places significant strain on agricultural communities and associated ecosystems. As temperature increases and water scarcity worsens, the avocado, a high-water demanding crop, faces declining yields and increased tree mortality. Deforestation, monoculture farming, and pesticide use further threaten interconnected landscapes, reducing biodiversity, degrading soil quality, and devaluing natural capital. Michoacán, Mexico, the largest producer of

Avocado drought stress alleviation through different soil amendments

Authors: Beyá-Marshall, Victor; Moraga, Felipe; Galaz, Bastián; Kremer, Cristián; Fichet, Thomas; Seguel, Oscar

"
Under the uncertain scenario of water availability for irrigation, plants are often exposed to drought periods, which can negatively impact their vegetative growth and yield potential. To address this issue, various soil amendments including inorganic, organic, and biological treatments, have been investigated as solutions for mitigating water stress. However, comparative studies of different amendments are lacking. The aim of this study was to assess the efficacy of various soil amendments

Accessible drone image processing for sustainable resource management of 3D tree-like crops using unsupervised algorithms

Authors: Xia, Xizhi; Sachar, Jaydeep; Alibhai, Khail; Labelle, Jeannifer; Demin, Dmitry; Sulle, Emmanuel; Kim, Woo Soo

This study presents a novel AI-driven solution designed to enhance sustainable resource management and increase accessibility for farmers through visualized and digitalized tree information. The proposed methodology includes optimizing drone mapping for effective data coverage, capturing high-resolution imagery, and generating a 3D Point Cloud, with a particular emphasis on the integration of Weighted K-means, Density-based spatial clustering of applications with noise (DBSCAN), and cluster separation

Avocado production in different biomes throughout Peru: do differing cultivation practices translate into differences in environmental impacts?

Authors: Elorrieta-Mendoza, Alvaro,; Sanchez-Matos, Joan; Bentín, Jorge; Debrock, Sébastien; Mathot, Claire; Stelian, Louis; Soengas, Beatriz; Kahhat, Ramzy; Vázquez-Rowe, Ian

PURPOSE: Avocado production in Peru takes place in different biomes and under different agricultural systems (e.g., conventional, organic, or agroforestry). Therefore, it is important to understand differences in the environmental profile of avocado production within the diversity of these cultivation systems. Hence, the main objective of the study was to conduct a cradle-to-gate attributional Life Cycle Assessment of avocado production in Peru by small and medium-sized producers, under multiple
