Abstract

This study aimed to assess the potential for energy recovery from waste generated by the peach processing industry in the Brazilan state of Rio Grande do Sul. The generation of semi-solid residues during the production of peach in syrup, as the potential for biogas, CH₄, and H₂ production through anaerobic digestion, was investigated. The undertaking of two different methodologies allowed us to estimate the potential for H₂ production and to facilitate comparisons. The processing ranges from 216 to 19,200 tons of fruit annually and generates 4800 tons.year⁻¹of semisolid residues. The results indicate that CH₄ production could reach 5.79E+05 m³ year⁻¹, giving a total electricity generation of 1.74E+06 kWh.year⁻¹. Additionally, a total H₂ production of 5.60E+06 m³ year⁻¹ was estimated. These findings suggest that the management of the waste bi-products from peach processing industry has significant potential for contributing to renewable energy generation.

加强巴西农业工业部门的生物质能回收：通过桃糖浆废弃物管理创新沼气、生物甲烷和氢气生产

本研究旨在评估巴西南巴西大德州（里约热内卢Grande do Sul）桃子加工业产生的废物中能源回收的潜力。研究了糖浆桃生产过程中产生的半固体残渣，以及通过厌氧消化产生沼气、CH4和H2的潜力。采用两种不同的方法使我们能够估计氢气生产的潜力，并便于比较。每年的水果加工量从216吨到19200吨不等，产量为4800吨。半固体残留物的年份−1。结果表明，年- 1 CH4产量可达5.79E+05 m3，年- 1总发电量为1.74E+06 kwh。此外，估计氢气总产量为5.60E+06 m3 /年。这些研究结果表明，对桃果加工废弃物的管理具有促进可再生能源发电的巨大潜力。
