Abstract
Madspild bidrager til globale CO2-udledninger, og mange apps sigter mod at hjælpe husholdninger med at spilde mindre. Inden for human-computer interaction (HCI) testes ofte prototyper, men vi ved mindre om, hvordan eksisterende løsninger bruges i hjemmet, og hvordan folk oplever deres effekt på madspild. Vi gennemførte 17 interviews om husholdningers madspild, hverdagens rutiner og erfaringer med at købe lykkeposer via Too Good To Go, og vi lavede 13 dagbogsstudier over to uger, hvor deltagerne registrerede mad, de smed ud, rester og køb i Too Good To Go. Vi fandt, at motivationer og holdninger er forskellige og påvirker, hvordan mad håndteres. Både Too Good To Go og måltidskasser kan give overraskelser og udfordringer; især det ukendte indhold i lykkeposer førte i nogle husholdninger til mere madspild. Alligevel fandt flere deltagere måder at indarbejde disse forhold i deres hverdag. Samlet viser resultaterne, at de samme teknologier kan mindske eller øge madspild alt efter, hvor godt de passer til husholdningers rutiner og forventninger.
Food waste contributes to global CO2 emissions, and many apps aim to help households waste less. In human–computer interaction (HCI) research, prototypes are often tested, but we know less about how people use existing tools at home and how they perceive their impact on food waste. We conducted 17 interviews about household food waste, everyday routines, and experiences buying magic bags through Too Good To Go, and we ran 13 two-week diary studies in which participants recorded discarded food, leftovers, and Too Good To Go purchases. We found that people’s motivations and attitudes vary and shape how they manage food. Both Too Good To Go and meal boxes can introduce surprises and challenges; in particular, the unknown contents of magic bags sometimes led to more waste in some households. Even so, several participants found ways to fit these issues into their daily lives. Overall, our results show that the same technologies can reduce or increase food waste depending on how well they align with household routines and expectations.
