Reducing Plastic Packaging and Food Waste Through Product Innovation Simulation: Household Behavioural Insights Around Packaging, Single and Reuse Options, and Food: 2021-2022

This dataset was produced as part of the project: Reducing plastic packaging and food waste through product innovation simulation, funded by the NERC (Ref: NE/V010654/1). The wider project was concerned with building a Discrete Event Simulation (DES) model that can simulate food and food packaging as it moves through a household, from purchase to disposal. This dataset is qualitative in nature and was created to inform the modelling process. Remote qualitative interviews were planned and conducted, and participants were also asked to fill out entries on a research diary covering 4 days within a 7 day period. The interviews were semi-structured, and questions relating to waste and food practices were planned around 4 main areas: general household background, daily routines, weekly routines and shopping habits, waste and disposal practices, and attitudes to potential innovation in food packaging. A fifth section was based on photo-elicitation, to gauge participant attitudes to ageing produce. The diaries provided to participants had a system of prompts and questions that aimed to capture the movement of particular food items through the home and practices related to this movement over four separate days. Image files could also be submitted by participants, either included in the text files or as email attachments to the researcher. Follow up interviews were planned, which would be conducted after the second diary entry was complete and returned, but time constraints meant that only one follow up interview was conducted. A screening questionnaire was used to recruit and select participants, which was disseminated through university research recruitment channels and through social media accounts set up for the project. Informed consent for this questionnaire was gained at that stage, but was also gained prior to the remote interview, for both the interview and the diary research. However, the questionnaire data was not analysed and is not included in the collection as it was for recruitment purposes only. The data collection is comprised of 28 interview transcripts, 25 completed research diaries and 91 image files (produced by research participants) as part of the research diaries. Where image files were included in text documents by participants, the image files have been extracted and saved as photographs separately. These are stored as .docx files and .tiff files accordingly. Each of these was anonymised according to the anonymization plan. As there are multiple forms of data for each participant, each participant that completed the questionnaire was given a unique identifier, with suffixes describing the type of data. These are described in the readme file for the data collection.

本数据集源自一项由自然环境研究委员会（NERC）资助的研究项目——"通过产品创新模拟减少塑料包装与食物浪费"（项目编号：NE/V010654/1）。该整体项目旨在构建离散事件模拟（Discrete Event Simulation, DES）模型，用于模拟食物及食品包装从购进入户直至最终处置的全流程居家流转过程。本数据集为定性数据集，旨在为该建模工作提供支撑。

研究团队规划并开展了远程定性访谈，同时邀请参与者填写为期7天周期内的连续4天研究日志。访谈采用半结构化形式，问题围绕四大核心领域设计：家庭基本概况、日常与周度作息及购物习惯、垃圾处理行为、以及对食品包装创新方案的态度；另有第五部分基于照片引导法（photo-elicitation），用于了解参与者对变质食材的态度。

研究人员向参与者提供的日志包含一系列提示与问题，旨在记录特定食品在居家环境中的流转情况，以及相关行为在4个独立日期内的细节。参与者可提交图像文件，既可嵌入文本文档，也可作为邮件附件发送给研究人员。

原计划在参与者完成第二份日志并提交后开展跟进访谈，但受时间限制，最终仅完成了1次跟进访谈。

研究通过高校研究招募渠道及项目官方社交媒体账号发布筛选问卷以招募参与者。参与者在填写问卷时已获取知情同意，且在远程访谈开始前，也针对访谈及日志研究获取了二次知情同意。不过，问卷数据仅用于招募环节，未进行分析且未纳入本数据集。

本次数据采集包含28份访谈转录文本、25份完整研究日志，以及随日志提交的91份由参与者创作的图像文件。若参与者将图像嵌入文本文档，研究团队已将图像单独提取并保存为图片文件，分别以.docx及.tiff格式存储。所有数据均已按照匿名化方案完成匿名处理。

由于每位参与者对应多种形式的数据，每位完成问卷的参与者均被分配唯一标识符，并通过后缀区分数据类型，相关细节已在本数据集的自述文件中说明。
