Advancing Energy Recovery: Evaluating Torrefaction Temperature Effects on Food Waste Properties from Fruit and Vegetable Processing

Processes, Journal Year: 2025, Volume and Issue: 13(1), P. 208 - 208

Published: Jan. 13, 2025

Most organic waste from food production is still not used for energy production. From the perspective of production, one option to valorise properties waste. The fruit juice industry growing rapidly and generates large amounts One main wastes in processing peach pits apple peels. aim this study was analyse influence torrefaction temperature on waste, namely peels, pea shells, order improve their value determine potential further use valorisation as a renewable source. different temperatures heating (HHV), mass yield (MY) (EY) better understand behavior thermal individual selected samples. process carried out at 250 °C, 350 °C 450 °C. obtained biomass compared with dried biomass. For HHV after (28 kJ/kg), MY decreased by (66–34%), while EY fell (97–83%). Peach pits, despite higher (18 achieved low (38–89%) (59–99%), which reduces efficiency biochar Pea peels had (82–97%) lower (11 but high ash content limits wider use. results confirm that, increasing temperature, all biomasses decrease, consequence degradation hemicellulose cellulose loss volatile compounds. In most cases, improved resistance moisture adsorption, related that causes structural changes. showed hydrophobic Temperature seen have great impact efficiency. Apple generally highest yield.

Synthesis of Turbostratic Graphene Derived from Biomass Waste Using Long Pulse Joule Heating Technique

Nanomaterials, Journal Year: 2025, Volume and Issue: 15(6), P. 468 - 468

Published: March 20, 2025

This study addresses the challenge of scalable, cost-effective synthesis high-quality turbostratic graphene from low-cost carbon sources, including biomass waste such as sugarcane leaves, bagasse, corncobs, and palm bunches, using Direct Current Long Pulse Joule Heating (DC-LPJH) technique. By optimizing carbonization process blending biomass-derived with black graphene, gram-scale production was achieved in just a few seconds. The involved applying an 18 kJ electrical energy pulse for 1.5 s, resulting temperatures approximately 3000 K that facilitated transformation atoms into well-ordered graphene. Structural morphological characterization via Raman spectroscopy revealed low-intensity or absent D bands, high I2D/IG ratio (~0.8–1.2), indicating monolayer formation. X-ray photoelectron (XPS) identified sp2-hybridized oxygenated functional groups, while NEXAFS confirmed presence graphitic features both sp2 sp3 bonding states. Energy consumption calculations DC-LPJH demonstrated 10 per gram, demonstrating potential production. work presents efficient approach producing applications enhancing properties composites, polymers, building materials.
