Turning Food Loss and Food Waste into Watts: A Review of Food Waste as an Energy Source

Energies, Journal Year: 2024, Volume and Issue: 17(13), P. 3191 - 3191

Food loss (FL) and food waste (FW) have become severe global problems, contributing to resource inefficiency environmental degradation. Approximately 6% of greenhouse gas emissions (GHGs) are derived from FW, which is usually discarded in landfills, emitting methane, a that 28 times more harmful than CO2. Diverting the path FW towards energy industry represents promising avenue mitigate impact save resources while generating substitutes. The Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) approach was utilized conduct systematic literature review on 10 different conversion processes used convert FL into energy. Anaerobic bioconversion integrated with pyrolysis emerges as potential eco-friendly solution management, nutrient recovery production various forms, including biogas, heat, biohydrogen biochar. Despite its potential, anaerobic digestion still faces some challenges related intermediate compounds (VOCs, NH3, H2S), necessitate precise process control optimization. Nonetheless, converting can provide economic benefits context circular economy. This offers insightful information stakeholders, academics policymakers who interested utilizing means producing sustainable by summarizing important findings ten waste-to-energy processing methods their improved efficiency.

Abstract To mitigate water shortages, mulched drip irrigation disrupts soil‐air gas exchange, disturbing the balance between production and diffusion in soil. This study explored effects of nitrogen (N) application aerated on soil microenvironment, greenhouse emissions root zone, processing tomato yields. The objective was to offer a theoretical framework scientific evidence guide fertilization practices, improve enhance crop productivity, especially under irrigation. Two methods (non‐aerated [A0] [A1]) two N rates (150 kg·hm⁻ 2 [N1] 270 [N2]) were tested. Results showed that increased organic carbon (SOC), dissolved (DOC), total (TN), ammonium (NH₄⁺‐N), while enriched content. Both aeration elevated N₂O CH₄ emissions. Path analysis revealed fertilization‐coupled indirectly influences carbon‐nitrogen cycling genes by altering nutrient levels, affecting Soil nutrients functional gene abundance directly impacted yield, with nitrate (NO₃⁻‐N) showing most substantial direct effect yield (direct path coefficient = −1.047***). Under A1N2 (aerated kg hm⁻ N), levels improved (total carbon: 25.19 g·kg −1 , SOC: 18.25 DOC: 93.65 mg·kg TN: 0.97 NH₄⁺‐N: 2.64 NO₃⁻‐N: 1.18 ), resulting 32.05 t 23.69% increase over A0N1. Aerated combined moderate is recommended for sustainable fertility However, mitigation strategies such as nitrification inhibitors or optimized schedules should be employed minimize
