“…These demonstrate the diverse potential of using these residues in modern technologies. Additionally, strategies like pyrolysis and gasification have been investigated [ 15 ], which, along with combustion, aim to harness the energy potential of these residues. However, the energy utilization of biomass, especially from agricultural residues like GHR, poses challenges due to its sensitivity to initial composition and weather conditions during collection.…”

The Colombian sugarcane industry yields significant residues, categorized as agricultural and industrial. While bagasse, a widely studied industrial residue, is employed for energy recovery through combustion, agricultural residues are often left in fields. This study assesses the combustion behavior of these residues in typical collection scenarios. Additionally, it encompasses the characterization of residues from genetically modified sugarcane varieties in Colombia, potentially exhibiting distinct properties not previously documented. Non-isothermal thermogravimetrical analysis was employed to study the thermal behavior of sugarcane industrial residues (bagasse and pith) alongside agricultural residues from two different sugarcane varieties. This facilitated the determination of combustion reactivity through characteristic combustion process temperatures and technical parameters like ignition and combustion indexes. Proximate, elemental, and biochemical analyses revealed slight compositional differences. Agricultural residues demonstrated higher ash content (up to 34%) due to foreign matter adhering during harvesting, as well as soil and mud attachment during collection. Lignin content also varied, being lower for bagasse and pith, attributed to the juice extraction and milling processes that remove soluble lignin. Thermogravimetric analysis unveiled a two-stage burning process in all samples: devolatilization and char formation (~170°C), followed by char combustion (~310°C). Characteristic temperatures displayed subtle differences, with agricultural residues exhibiting lower temperatures and decomposition rates, resulting in reduced ignition and combustion indexes. This indicates heightened combustion reactivity in industrial residues, attributed to their elevated oxygen percentage, leading to more reactive functional groups and greater combustion stability compared to agricultural residues. This information is pertinent for optimizing sugarcane residues utilization in energy applications.

Over the years, agricultural management practices are being improved as they integrate Information and Communication Technologies (ICT) and Precision Agriculture tools. Regarding sugarcane crop production, this integration aims to reduce production cost, enhance input applications, and allow communication among different hardware and datasets, improving system sustainability. Sugarcane mechanization has some particularities that mandate the development of custom solutions based on digital tools, which are being applied globally in different crops. Digital mechanization can be conceived as the application of digital tools on mechanical operation. This review paper addresses different digital solutions that have contributed towards the mechanization of sugarcane crop production. The process of digitalization and transformation in agriculture and its related operations to sugarcane are presented, highlighting important ICT applications such as real-time mechanical operations monitoring and integration among operations, demonstrating their contributions and limitations regarding management efficiency. In addition, this article presents the major challenges to overcome and possible guidance on research to address these issues, i.e., poor communication technologies available, need for more focus on field and crop data, and lack of data interoperability among mechanized systems.

Reducing the environmental impact of residues generated by the Brazilian agroindustry can be achieved through the utilization of sugarcane bagasse, a biomass resource widely employed. However, this biomass's high moisture content results in low energy production efficiency. The conversion of sunlight into thermal energy using Concentrated Solar Energy (CSE) has emerged as an efficient alternative for the sugarcane bagasse drying process. In this study, we propose to experimentally evaluate and numerically simulate, employing the Finite Element Method (FEM) and the ABAQUS software, a solar concentrator receiver utilized in the drying process. The methodology employed comprises two modeling phases: an experimental phase, wherein two solar concentrators were constructed within a metallic structure, each with distinct surface areas and a panel of adjustable flat mirrors designed to focus solar radiation on a central point—the reactor. Experiments were conducted involving water, sugarcane bagasse, and reactor characterization. Subsequently, a numerical modeling phase was carried out, analyzing two scenarios: a stationary one and a transient one accounting for temperature variations over time. FEM simulations were conducted using the ABAQUS program. The results obtained from the experiments underscore the significance of radiation reaching the reactor as the primary factor in achieving the required efficiency for drying sugarcane bagasse. This finding was corroborated by the numerical simulations, which considered thermal gradients and thermal stress.
