Materials for Renewable and Sustainable Energy, Journal Year: 2024, Volume and Issue: 13(1), P. 27 - 43

Published: Jan. 24, 2024

Abstract Briquetted biomass, like sugarcane bagasse, a by-product of sugar mills, is renewable energy source. This study aimed at the production and characterization bagasse briquettes. The briquettes was carried out with different blending ratios (5, 10, 15%) average particle sizes (0.75, 2.775, 4.8 mm) various binders cow dung, waste paper, admixture (molasses wastepaper). underwent drying, size reduction, sieving, binder addition, densification using manual press during briquetting process. Characterization physical combustion parameters briquettes, such as density, shatter resistance, proximate, calorific value, followed American Society for Testing Materials procedures. result shows that maximum density 0.804 g/cm 3 , while resistance varied from 83.051 to 94.975% (4.8mm, 5% dung 0.75mm, respectively). ANOVA analysis showed factors their interactions had significant influence ( p value < 0.05) on properties. optimum achieved were 14.953% binder, 0.776 mm size, 0.805 95.811% resistance. Bagasse high 39927.05 kcal/kg. ultimate revealed composition 47.49% carbon (C), 5.133% hydrogen (H), 1.557% nitrogen (N), 0.374% sulfur (S), 45.446% oxygen (O). Therefore, has can be used replace fossil fuel firewood in applications. In due its availability, utilizing source economic advantage. Graphical abstract

Empirical Assessment of the Efficiency of Poland’s Energy Transition Process in the Context of Implementing the European Union’s Energy Policy

Energies, Journal Year: 2024, Volume and Issue: 17(11), P. 2689 - 2689

Published: June 1, 2024

This article addresses one of the contemporary economy’s most challenging endeavors: energy transition. Specifically, aim study was to assess effectiveness Poland’s transition process between 2004 and 2021. A comprehensive approach is employed analyze process, focusing on implementation through Energy Transition Effectiveness Index. methodology incorporates four dimensions, namely security, economic considerations, climate impact, social aspects, each characterized by 22 sub-indices. The research employs a two-tiered based multi-criteria decision making methodology. EDAS method utilized determine indices’ values, while CRITIC, equal weights, statistical variance methods Laplace’s criterion are ascertain sub-indices values dimension particularly useful for under uncertainty. Moreover, relationship these indices, Index, Gross Domestic Product explored. By evaluating from 2021 comparing results with other European Union countries, it becomes evident that varies over time. Despite encountering challenges during sector’s transformation, Poland exhibits positive progress in its efforts, outperforming certain counterparts. However, there pressing need intensify efforts curtail emissions enhance renewable utilization. Union’s support coordination deemed crucial facilitating endeavors, alongside fostering wider adoption best practices among member states. developed stands as valuable tool ongoing evaluation transformation processes across nations.
