Abstract

Reusable glass bottles are experiencing a resurgence, driven notably by societal concerns and regulations. While single-use glass bottles generally have higher environmental footprint compared to plastic bottles, reusable systems could reduce both impacts related to single-use (e.g., climate change, energy consumption) and plastics (e.g., microplastic pollution). The environmental benefits of reusable bottles can vary across systems and this can be overlooked by stakeholders who rely on generic results for communication and a limited number of parameters to design their systems. This study addresses this gap by developing a systematic analysis of the variability of life cycle assessment results, within the specific case study of a new beverage. As a result, a list of key parameters to consider for the specific case study is set, enabling to propose targeted mitigation strategies. The commonly used generic key parameters are complemented with context-specific key parameters, empowering stakeholders to develop efficient systems and communicate their environmental performance accurately. Different configurations are likely to be influenced by other key parameters, and require specific mitigation strategies. In this perspective, stakeholders need assistance in: (1) designing context-specific strategies, and (2) translating – complex and plural – life cycle assessment results into actionable decisions.

基于生命周期评估的可重复使用玻璃瓶方案优化,使用针对具体情况的关键参数
在社会关注和法规的推动下,可重复使用的玻璃瓶正在重新兴起。虽然与塑料瓶相比,一次性使用的玻璃瓶通常对环境的影响更大,但可重复使用的系统可以减少与一次性使用(如气候变化、能源消耗)和塑料(如微塑料污染)相关的影响。可重复使用瓶在不同系统中的环境效益可能会有所不同,这一点可能会被利益相关者所忽视,因为他们依赖于通用的结果来进行交流,并依赖于有限的参数来设计他们的系统。本研究针对这一缺陷,在新饮料的具体案例研究中,对生命周期评估结果的可变性进行了系统分析。因此,为具体案例研究制定了一份需要考虑的关键参数清单,从而能够提出有针对性的缓解策略。常用的通用关键参数与特定环境下的关键参数相辅相成,使利益相关者能够开发高效的系统,并准确传达其环境绩效。不同的配置可能会受到其他关键参数的影响,因此需要特定的缓解策略。从这个角度来看,利益相关者需要在以下方面得到帮助:(1)设计针对具体情况的策略;(2)将复杂而多元的生命周期评估结果转化为可操作的决策。
