Planeat

Designing Sustainable Solutions to Minimize Food Waste

OVERVIEW

Creating a sustainable lifestyle through smarter meal planning

Planeat is a mobile app addressing food waste through personalized meal planning and gamification elements that naturally guide users toward eco-friendly habits. Built as my capstone project at the Cyber University of Korea, the app leverages AI technology to deliver an intuitive user experience.

MY ROLE

I independently drove the end-to-end design process from research to prototyping, creating user-centered solutions based on research insights.

Food Waste is One of the Largest Drivers
of Global
Greenhouse Gases

One of the most critical environmental challenges today is the climate crisis. Food waste is the third-largest source of greenhouse gas emissions worldwide, emitting about 2.5 billion tons of waste annually. While emissions from energy and transportation sectors are often emphasized, the impact of food waste is equally significant.

Korea's Food Waste Crisis:
Small Changes, Massive Impact

In Korea, 70% of food waste comes from our homes and restaurants : mostly from leftovers and expired ingredients. Cutting this waste by just 20% would have the same impact as planting 360 million pine trees.

INSIGHT

Poor Planning and
Purchasing Habits
Drive Food Waste

Research reveals that poor meal planning and impulsive buying are key drivers of food waste. Many people struggle to develop sustainable eating habits simply because they're unfamiliar with effective food management strategies.
