This review explores the potential for adding value to these residues through various chemical and biochemical processes, aiming to mitigate their environmental impact. Chemical processes, including pyrolysis, gasification, combustion, and transesterification, convert biomass into biochar, bio-oil, syngas, and biodiesel, respectively. Biochemical processes, such as anaerobic digestion, fermentation, composting, and enzymatic hydrolysis, produce biogas, biofuels, and soil amendments. These methods not only reduce greenhouse gas emissions and improve waste management but also enhance soil health and promote a circular economy. Despite challenges in technological development, policy support, and public awareness, the integration of these processes within biorefineries holds promise for maximizing resource efficiency and sustainability.

Heavy reliance on non-renewable energy sources causes significant environmental harm and results in high costs, making renewable resources essential. Biodiesel, a non-toxic and environmentally friendly fuel, closely resembles conventional fossil fuels. It is derived from renewable sources such as palm oil, animal fats, and non-edible seeds. Biodiesel offers notable benefits, including reduced generation of greenhouse gases (GHGs) and hazardous air pollutants. Despite these advantages, widespread adoption of biodiesel remains challenging. This study explores the various non-edible seeds obtained from indigenous plants in Bangladesh, physico-chemical properties of these extracted oil, biodiesel production, and their engine performance study. Among the reported fifteen seeds, the oil content was found to be the highest in Eucalyptus seed (50%–60%), followed by Jatropha, Rubber, Mahua and so on. Stearic acid (C18:0), Oleic acid (C18:1) and Linoleic acid (C18:2) were commonly found in all the seeds whereas the maximum content of palmitic acid and Oleic acid was found in cotton seed oil. The biodiesel yield during the trans-esterification process was found about 95%. A Biodiesel blend of 15%–20% with commercial diesel was found acceptable for smooth performance of the existing engines.

An inherent problem with most conventional global maximum power point tracking (GMPPT) algorithms is that they do not distinguish local and global peaks, and thus energy extraction may not be optimal. To eliminate this, this paper proposes an Adaptive Neuro-Fuzzy Inference System-Genetic Algorithm (ANFIS-GA) solution in improving the GMPPT performance under diverse shading conditions. The ANFIS is ideal in modeling the nonlinearity and uncertain nature of PV systems; the Genetic Algorithm (GA) then dynamically determines the optimal Proportional–Integral–Derivative (PID) controller parameters by minimizing the error between the actual power output and the maximum power output calculated in ANFIS. This means that this controller can respond to nonlinear and time-varying nature of a DC–DC SEPIC converter, enhancing response time and stability in various operating conditions. The proposed ANFIS-GA method, simulated with MATLAB/Simulink, was evaluated in three environments, i.e., no shading, partial shading, and severe shading, and performances were 99.98%, 98.5%, and 97.67% (GMPPT efficiencies), respectively. Besides, a comparative test to ANFIS-only systems at 400 W/m<sup>2</sup>, 700 W/m<sup>2</sup>, and 1000 W/m<sup>2</sup> also revealed that the hybrid methodology better tracked the global peak particularly in an oscillating environment. Furthermore, to test the strength of the controller, time-varying irradiance profiles that would simulate the real-world cloud motions using randomized step-wise changes are applied to it. The system sustained efficiencies better than 98.5% in such difficult conditions using convergence times that were below 0.25 s. These findings support that the ANFIS-GA approach has a high degree of flexibility, accuracy, and consistency, and it is thus an effective method in improving PV performance in a complex and dynamically varied systems.</div></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"3 4","pages":"Article 100239"},"PeriodicalIF":0.0,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144604957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cement mortars are widely used around the globe, and integrating lightweight and insulating aggregates such as sand replacements offers better energy efficiency and minimize energy losses in buildings. The techno-economic analysis in this work evaluates composite mortars by incorporating aerogel, expanded clay, and expanded polystyrene aggregates, in line with European standards EN998-1. Their performance is assessed as a function of percentage sand replacement, thermal conductivity, compressive strength, density, and cost. Integrating insulating aggregates reduces compressive strength and density, impacting mechanical resistance and structural weight. Therefore, this analysis identifies the optimal material composition by replacing sand with 67% aerogel and 100% expanded clay and expanded polystyrene to maintain a balance between thermal and mechanical performance. It is perceived that the aerogel exhibits the best insulation properties, but they are the most expensive candidate. The techno-economic analysis also examines the optimal thickness, revealing that expanded polystyrene can reduce energy consumption by up to 86% at the break-even point, though it requires an impractically thick layer of over 8 cm. The decision support system developed in this study recommends expanded polystyrene as the most cost-effective option for achieving 50% energy savings and CO<sub>2</sub> reduction of up to 68%.</div></div>","PeriodicalId":100598,"journal":{"name":"Green Technologies and Sustainability","volume":"3 4","pages":"Article 100238"},"PeriodicalIF":0.0,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144489699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the results indicate that life expectancy could be increased by implementing policies that boost aquaculture output, real income, and food production. Aquaculture production subsidies, tax incentives for food production, and investments in infrastructure might all be part of such plans. As a second takeaway, the results question the wisdom of initiatives that increase people’s protein intake.

These algorithms include Pearson correlation, hierarchical clustering, and decision tree (DT) models. Results indicate that nanoparticles such as graphene oxide (GO), reduced graphene oxide (rGO), hydrolysis lignin, and calcium carbonate improve mechanical properties, with MOR values of 27.38–52.65 MPa and MOE of 2591.6–4680 MPa, meeting EN312 load-bearing standards. Zinc oxide nanoparticles yield superior dimensional stability by achieving a low TS of 9.33%. However, according to the American National Standard for Particleboard (ANSI/A208.1-1999), most nanoparticle boards produced met general-purpose standards except for WA and TS, which exceeded the maximum limits of 8% and 3%, respectively. Only crosslinked chitosan and zinc oxide nanoparticle panels meet the minimum requirements for TS (17%) and the maximum MOR (11.00 MPa) and MOE (1,800.00 MPa) for general purposes in dry conditions (furniture and interior fitments) according to the Brazilian standard (ABNT NBR). The Pearson correlation analysis reveals a strong relationship between board properties (R = 0.94 for WA–TS; R = 0.93 for MOR–MOE), confirming that nanoparticle treatments enhance performance while maintaining inherent material behavior. Hierarchical clustering grouped nanoparticles by performance: zinc oxide and chitosan+UF+epoxy formed a cluster with the lowest WA and TS, indicating optimal dimensional stability, while GO, rGO, and chitosan-based composites clustered with moderate values. For mechanical properties, APTES-modified nanocellulose, aluminum oxide, and zinc oxide formed a high-performance cluster (high MOR, MOE, IB).
