Households around the world throw away large amounts of fruits and vegetables simply because they spoil before being used. This waste is not just costly—it's also bad for the environment. At the same time, many people struggle to eat fresh produce regularly due to busy schedules or poor meal planning. One way to address both problems could be a refrigerator that automatically turns aging produce into juice before it goes bad.

How It Would Work

The idea involves a smart refrigerator with built-in sensors and AI that monitors the freshness of stored fruits and vegetables. When the system detects that produce is starting to spoil, it automatically juices it, preserving nutrients and reducing waste. Users could customize preferences—like juice combinations or timing—through a companion app. Over time, the system could expand to include features like smoothie blending or recipe suggestions for aging ingredients.

• For consumers: Convenient way to reduce waste and consume more nutrients
• For manufacturers: Opportunity to differentiate products in a competitive market
• For retailers: Chance to sell innovative appliances aligned with sustainability trends

Getting Started

Instead of building a whole new fridge right away, one could begin with a simpler approach: a juicer attachment for existing smart refrigerators, paired with an AI camera that scans produce and suggests when to juice. This modular version would be easier to test and refine with early adopters before developing a fully integrated, high-end appliance.

Key questions to explore would include how accurately the AI can detect spoilage across different types of produce, whether users find the automation valuable enough to justify potential cost increases, and how to design the juicing mechanism for easy cleaning. Existing technologies like food recognition APIs could help validate the AI component, while surveys could gauge consumer interest in such features.
