摘要

食物垃圾的价值化有助于减轻食物垃圾的环境和经济负担,并向循环经济过渡。FW定价过程已被广泛研究,以生产各种最终用途产品并对其进行总结;然而,它们的经济、环境和社会方面是有限的。本研究综合了FW管理中使用的一些定价方法,并生产了各种应用的增值产品,还讨论了技术进步及其环境、经济和社会方面的问题。在全球范围内,每年有13亿吨可食用食品损失或浪费,在此期间排放了约33亿吨温室气体。FW对环境(−347至2969千克二氧化碳当量/吨FW)和经济(−100至138美元/吨FW)的影响取决于食物链和废物管理系统的多个参数。尽管正在做出巨大努力来减少FW,并对不可避免的FW进行估价,以减少环境和经济损失,但似乎跨学科的方法/举措对于最大限度地减少FW和减轻FW的环境影响至关重要。利益相关者的共同努力是减少FW以及提高FW可持续性的有效定价的关键。然而,任何减少食物浪费的举措都应该考虑更广泛的可持续性检查,以避免投资和环境风险。

A Review on the Challenges and Choices for Food Waste Valorization: Environmental and Economic Impacts

Valorization of food waste (FW) is instrumental for reducing the environmental and economic burden of FW and transitioning to a circular economy. The FW valorization process has widely been studied to produce various end-use products and summarize them; however, their economic, environmental, and social aspects are limited. This study synthesizes some of the valorization methods used for FW management and produces value-added products for various applications, and also discusses the technological advances and their environmental, economic, and social aspects. Globally, 1.3 billion tonnes of edible food is lost or wasted each year, during which about 3.3 billion tonnes of greenhouse gas is emitted. The environmental (−347 to 2969 kg CO2 equiv/tonne FW) and economic (−100 to $138/tonne FW) impacts of FW depend on the multiple parameters of food chains and waste management systems. Although enormous efforts are underway to reduce FW as well as valorize unavoidable FW to reduce environmental and economic loss, it seems the transdisciplinary approach/initiative would be essential to minimize FW as well as abate the environmental impacts of FW. A joint effort from stakeholders is the key to reducing FW and the efficient and effective valorization of FW to improve its sustainability. However, any initiative in reducing food waste should consider a broader sustainability check to avoid risks to investment and the environment.
