Gamification for Enhanced Recycling Engagement in Circular Economies

This paper presents the Transformers project, a gamified, web-based application designed to counter declining public engagement with Germany's complex recycling system. Grounded in behavioural research, the authors identify knowledge gaps, invisible environmental impact, and a lack of feedback as the principal barriers to participation. Existing tools such as GoBeEco, RecycleMich, JouleBug, and Sensoneo are found to lack an integrated combination of modular learning, real-time tracking, and personalised feedback, which the Transformers platform seeks to provide.

The application combines a progress dashboard, time-bound challenges, micro-learning modules with quizzes, sorting simulations, leaderboards, and rewards, and is built on Self-Determination Theory. Partner-designed challenges allow local adaptation. The work follows a Design Science Research methodology, drawing on expert interviews, a half-day co-design sprint with ten participants, and student prototyping.

Evaluation consisted of expert workshops and usability testing with a municipal representative and four recycling-industry stakeholders. Feedback praised the real-time feedback, challenge flexibility, and analytics, while recommending clearer communication and improved visual presentation. Testing was confined to a university setting with environmentally interested users, so the authors acknowledge that broader and longer-term evaluation across diverse populations is still required.

Notably, the paper reports no quantitative behavioural or outcome data for the app itself. Its evidentiary base rests on conceptual framing, qualitative stakeholder input, and a reference list that mixes academic literature from 2008 to 2025 with industry case studies, though that list contains some duplicated and incomplete citations.
