This master's thesis explores the issue of household food waste through the Speculative Design (SD), focusing on how the participatory method of the futures cards game can serve as a bridge between food waste policy and everyday household practices. Despite the political objectives set by the European Union and Estonia to reduce food waste, the problem continues to deepen, with households representing the largest source of avoidable waste. Based on this context, the research asks: How can SD techniques be used as a resource to reduce the gap between policy initiatives and everyday household practices? The study follows a qualitative, three-stage methodology. In the first stage, a workshop was conducted using futures cards to co-create speculative future scenarios and map participants values. In the second stage, one of the scenarios was developed into a video prototype titled "My Kitchen 2025", which presented both a positive and a negative speculative future narrative in the context of household food waste. In the third stage, participants watched the video and reflected critically on the issues it raised. The findings indicate that SD techniques helped participants imagine alternative futures and critically engage with themes such as technology, automation, responsibility, and sustainability. The video prototype made abstract ideas emotionally resonant and highlighted how people perceive control, trust, and functioning within technological systems. The thesis concludes with specific recommendations for future food waste policy development, emphasizing transparency, opportunities for participation, and attention to everyday user experience and behavioural barriers. In conclusion, the results suggest that SD can serve as a meaningful technique to connect political food waste reduction goals with actual household practices.
