Food wastage is a major problem that envelopes the USA. 40% of the produce in the USA ends up in landfills, while 12.7% of the population struggles to find food according to the United States Department of Agriculture in 2015. The issues revolving around food and food wastage is a major problem seen today in the USA. In the meantime, there has been a rise of “smart devices” with the rapid growth of technology. Refrigerators have also been made “smart”, by attaching a screen and internet, allowing more electronic features to be added to the conventional style.


Our team believes that technology can play a pivotal role in fighting food wastage from our homes. Our study focuses on food wastage and the role of refrigerators to determine whether modern-day refrigerators are smart enough to help us out with the problems of food wastage. In order to investigate this, the team conducted four interviews. The interviewees reflected the wide range of potential smart fridge users in various perspectives. This gave us a deep understanding of the interaction between users and their fridges at home, and their personal fridge usage. In this report, we bring the four interviews together in order to gain extensive knowledge on what users value when using a refrigerator.
