Abstract: This study aims to evaluate the quality of second-generation bioethanol obtained from agro-food waste consisting of tropical fruit peels (banana, papaya, and pineapple). Fresh fruit peels were collected, sorted, and stored at 4°C. Fermentation was carried out in four fermenters, followed by simple distillation (78–80°C), rectification, and dehydration using magnesium sulfate to obtain high-purity bioalcohol. The results obtained are comparable to those reported in scientific literature, confirming the feasibility of producing bioethanol from biodegradable waste such as fruit peels: the boiling points of the four distillates—derived from banana, papaya, and pineapple peels, as well as a mixture of the three—were around 78°C. The pH values of the four distillates were all around 7. The densities of the.....

Abstract: Carbon dioxide (CO₂) emissions arising from fossil fuel combustion, industrial processing, and energy-intensive activities have become a major contributor to global climate change and environmental degradation. The urgent need for sustainable carbon mitigation technologies has accelerated research into advanced porous materials capable of efficient carbon capture and storage. Organic framework materials, including Metal–Organic Frameworks (MOFs), Covalent Organic Frameworks (COFs), Porous Organic Polymers (POPs), Covalent Triazine Frameworks (CTFs), and Hydrogen-Bonded Organic Frameworks (HOFs), have emerged as highly promising adsorbents because of their exceptionally high surface area, tunable pore architecture, structural diversity, and superior....
