As the world addresses increasing demand for sustainable energy solutions, biodiesel has surfaced as a viable alternative to conventional fossil fuels. The expansion of feedstock plantations, particularly palm oil in tropical regions, can lead deforestation, loss biodiversity, and significant carbon emissions from destruction carbon-rich ecosystems. That is why this article focuses on production waste sources order maintain balance ecosystem. This review paper discusses global landscape need renewable environmentally friendly alternatives. It explores various depth that are investigated production, comprising cooking oil, animal fats, algae, other organic residues. Each analyzed its viability, challenges, economic feasibility production. A critical assessment different methods, such transesterification, pyrolysis, thermochemical conversion, anaerobic digestion, thermal cracking, hydro-treating enzymatic processes, presented, highlighting key factors influencing their efficiency scalability. Recent developments enhance waste-derived production's sustainability viability meet UN Sustainable Development Goals also highlighted. Furthermore, environmental impact biodiesel, including greenhouse gas land use, discussed provide holistic understanding ecological footprint. significantly increase brake engine along with substantial decrease like CO HC. However, NOx CO2 increased application sources. be reduced by exhaust recirculation selective catalytic reduction techniques. regulatory frameworks standards governing sources, emphasizing harmonized policies encourage widespread adoption. concludes outlining future research directions potential breakthroughs could further effectiveness, sustainability, scalability Waste Cooking Oil (WCO) fats currently most economically feasible options due low cost established collection processing infrastructure. Algae present high but require technological advancements reductions become viable. aims assist researchers, policymakers, industry stakeholders advancing utilization materials promoting more landscape.

In response to increasing global waste generation due population growth, urbanization, and industrialization, wastewater treatment operations should shift from being solely energy consumers becoming producers by harnessing sludge (WWS). This approach holds great potential for meeting demands addressing the challenges of treatment. The recovery heat electrical WWS offers a viable solution reduce costs within WWTPs. Thermochemical technologies such as pyrolysis, gasification, combustion hold their efficiency, reaction times, retrieval capabilities. These demonstrate feasibility in terms operational costs, circular economy principles, socio-environmental impact, thanks ongoing advancements waste-to-energy research. review aims explore recovering bioenergy (biogas or syngas) generate energy, including heat, electricity, other innovative products. article provides critical comprehensive examination thermochemical technologies, taking into account technological, economic, factors. It then presents integration techniques that effectively combine anaerobic digestion with conversion enhance syngas, biogas, flue-gas energy. results this study underscore significant sludge-to-energy schemes.

Bark is one of the main wastes chemical and mechanical processing Eucalyptus globulus wood. The proposed biochemical bark via saccharification pathway involves steam explosion (SE) pretreatment (severity factor log R0 4.22) followed by enzymatic hydrolysis using an cocktail composed cellulolytic xylanolytic enzymes. Almost 70% cellulose was achieved. remaining cellolignin residue (CLEZ) analysed for its composition structural features conventional wet chemistry methods a series spectroscopic tools (FTIR-ATR, solid-state CP/MAS 13C NMR spectroscopy wide-angle X-ray scattering (WAXS)). CLEZ component (about 51%) acid-insoluble lignin, which in terms ratio syringyl (S), guaiacyl (G) p-hydroxyphenyl (H) units (70:28:2) very close to that initial bark. This lignin highly condensed structurally associated with tannins, makes recalcitrant delignification common methods. About third eucalyptus after SE inaccessible remained CLEZ. cellulose, similar microcrystalline imbedded into lignin-tannins matrix extremely difficult purify. In contrast hemicelluloses were effectively removed hydrolysis, only small amounts (<2%) Among other ingredients, proteins inorganic/organic salts most abundant. latter includes noticeable calcium oxalate phytoliths (up 9%), Fe Si salts. eventual application areas are discussed.

In the context of escalating energy demands and quest for sustainable waste management solutions, this paper evaluates efficacy three machine learning methods—ElasticNet, Decision Trees, Neural Networks—in predicting recovery from municipal across European Union. As renewable sources increasingly dominate production landscape, integration Waste-to-Energy (WTE) processes presents a dual advantage: enhancing contributing to mix. This study leverages dataset incorporating economic environmental indicators 25 countries, spanning 2013–2020, compare predictive capabilities models. The analysis reveals that Networks, with their intricate pattern recognition capabilities, outperform ElasticNet Trees in metrics, as evidenced by superior performance key statistical such R-value, Mean Squared Error (MSE), Absolute (MAE). comparative not only demonstrates effectiveness each method but also suggests Networks pivotal tool informed decision-making policy formulation. Through investigation, contributes discourse, emphasizing critical intersection advanced technologies, considerations, stewardship addressing contemporary challenges.
