Abstract

Life Cycle Assessment (LCA) is acknowledged to be suited for the assessment of the energy-environmental burdens of foods, which are estimated to be overall one of the main impact sources worldwide. A right nutrition is even more fundamental for the healthy growing of the population, which has now, however, to consider ever more the aspect connected to its environmental impact. Under this perspective, this study aims at exploring the environmental burdens associated with a local university canteen for students through the application of LCA to a set of meal combination scenarios offered weekly to consumers. For the assessment, the authors designed a set of eight meal alternatives to create four daily meal combinations (DMCs), assuming 150 customers frequent the canteen service daily. Sixteen DMC scenarios based on a 1-to-3 weekly offer frequency have been tested. Results show the environmental impacts are highly affected by the food content and the weekly offer frequency, with the largest contributions coming when higher frequencies are combined with more impactful foods in the menus. The study highlights, overall, that global warming, eutrophication, acidification, and the depletion of the abiotic elements are the most relevant indicators for such an evaluation. The study aims at building a more sustainable and resilient future for the planet, starting with producing and consuming foods that are ecologically responsible, fair and accessible, local, healthy and safe, and waste free.

意大利南部一所大学食堂餐饮菜单的生命周期评估。
生命周期评估(LCA)被认为适用于评估食品对能源和环境造成的负担,据估计,食品是全球主要的影响源之一。合理的营养对人口的健康成长更为重要,但现在必须更多地考虑其对环境的影响。从这个角度出发,本研究旨在通过将生命周期评估应用于每周向消费者提供的一套膳食组合方案,探索与当地一所大学学生食堂相关的环境负担。为了进行评估,作者设计了一组八种膳食替代品,以创建四种每日膳食组合(DMC),假设每天有 150 名顾客经常光顾食堂服务。根据每周 1 到 3 次的供应频率,对 16 种 DMC 方案进行了测试。结果表明,食物内容和每周供应频率对环境影响很大,当频率越高,菜单中对环境影响越大的食物组合对环境影响最大。研究强调,总体而言,全球变暖、富营养化、酸化和非生物元素枯竭是此类评估最相关的指标。这项研究旨在为地球建设一个更具可持续性和复原力的未来,从生产和消费对生态负责、公平、可获得、本地化、健康、安全和无浪费的食品开始。

期刊介绍: The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere. The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
