Food waste is a serious problem. In US alone, we throw away 40 percent of our food supply every year. Inspired by both my personal experience as well as this global issue of consumer food waste, I decided to take a closer look at the problem and see if new technologies and UX design can be applied to come up with some solutions.
Research and Design
May to July 2018
I started by doing survey in my friends and families to see if people care about food waste at home. The results came positive.
78.3% of people will make plans to eat expiring food first, and most people are not using any existing tools to track food expiration.
I later realized that I measured “food waste” with relative frequency which turned out not ideal, and I didn’t take into consideration of other factors like commute time and reasons for tossing away food. Those were some deciding factors in launching a 2nd round of optimized survey afterwards.
After first round of Survey, I identified some target audience with problems of food waste at home and reach out with email invites. In the end I was able to talk to 9 of them, some of which are complete strangers, and some are coworkers, friends. During the interview I was able to identify pain-points and causes of food waste during the whole food consumption experience and ultimately helps with setting up persona/user journey.
“American’s fridge is so deep and big! Some families even have a second fridge and they’re packed!”
“Maybe it’s related to the car and travel culture in the states. Grocery stores tend to spread out more, so whenever people go grocery shopping they’re buying not for the day but for several days/a week.
“Age also plays a big part, elder retired people tend to have more free time to go shopping and they care more for the freshness of the food.”
This MTurk HIT with the survey questions was distributed to 50 people with a full time job. This Round I studied what are the main reasons of food waste at home, whether Costco membership has impact on food waste at home, and some other factors that could help me refine my persona.
To my surprise, in my sample, ownership of Costco membership(or alike) doesn’t seem to be a significant factor in food waste amount.
However, I do find that people who’re more willing to try different recipes are more likely to toss out more food. Their rate of throwing out 5-10 items a month is at 45% compared to 25% of the opposite.

Feel in control of everything at home while being a working mom.
She tries to plan the meals over the week ahead but has not been very effective. Out of sight, out of mind. As things stacked up, it’s harder to remember what she has put in the fridge.

Responsibility and care for the family, being economic
During the weekends, he can’t figure out what to cook without digging into the fridge to see what ingredients are still fresh.
“Although good planning would benefit me for sure, I might not want to be forced to do it.”
"The current functionalities seems to be a bit overkilling, and the adoption could be better if you start small and grow to fuller scale."
“Collaborating with online-grocery shopping could get you expiration info to start with.”
Design an app that helps users easily track food they buy and consume, provide recipe suggestions based on ingredients they have in order to help users prioritize eating the food that is close to expire to ultimately reduce food waste.
User can connect her account to Amazon so her ingredients bought from Amazon Fresh could be automatically going into her storage.
User can view storage by Type, Recent and close to expire.
User can use photo scan to add a single item.
User can use voice input to add an item and its amount.
This idea is designed for bulk addition of items that requires less effort from users. However, we need to get business buy-in from big grocery stores like Safeway, Trader joe's, etc to actually open their user data.
The recipes are suggested based on ingredients from your storage, and could help people prioritize which ingredients to use first.
In order for the app to suggest recipes, we also need to build a recipe system that is powerful and evolving.
I'm currently in this prototyping and testing phase, and I'm expecting more iterations based on testing insights. Keep an eye on the updates!
