ReLoop

ReLoop — Circular Electronics Companion

Why this problem matters

Electronic devices are often replaced or discarded before people have a clear, safe way to decide whether repair, reuse, donation, or responsible recycling is the better next step. ReLoop turns that confusing moment into a fast, transparent decision flow designed around the Earth Forward theme: keep useful electronics in circulation longer and make responsible end-of-life choices easier.

What ReLoop does

ReLoop asks for a small set of non-identifying device signals: device type, approximate age, functional condition, physical condition, battery/power health, repair confidence, and second-life potential. It then produces:

• a transparent Circularity Score;
• one of four practical pathways: Keep / Repair, Reuse / Donate, Repair First, or Responsible Recycling;
• a short action plan explaining what the user should do next;
• illustrative circularity indicators, clearly labeled as decision-support estimates rather than scientific lifecycle or carbon-accounting measurements.

A safety-first override changes the recommendation when battery or power concerns are present, so the product never encourages risky experimentation with questionable electronics.

Originality

Instead of building another recycling directory or generic sustainability page, ReLoop focuses on the decision before disposal. The product asks: “Does this device still have useful life, and what is the safest circular pathway from here?” The scoring model is deliberately understandable rather than a black-box prediction.

Earth Forward adherence

The entire product is built around extending useful device life, enabling reuse/donation, encouraging repair where appropriate, and routing devices toward responsible recycling when continued use is no longer sensible. The environmental theme is the core workflow, not a decorative feature.

Privacy-first design

The assessment runs entirely in the browser. ReLoop does not require an account, serial number, photo, precise location, or identity information, and the current assessment does not send user inputs to a backend.

Technology

ReLoop uses HTML5, CSS3, vanilla JavaScript, and a tiny dependency-free Node.js HTTP server. The recommendation engine is rule-based so every factor is inspectable. A production health endpoint supports deployment verification, and the application is deployed on Railway.

The technical challenge was not adding unnecessary infrastructure; it was creating a deterministic recommendation system that balances circularity, usefulness, user confidence, and safety while remaining transparent enough for a user to understand.

Design and UX

The interface is responsive for mobile and desktop, keeps the assessment short, presents the result as a clear pathway rather than a vague score, and puts the safety warning ahead of convenience whenever power/battery signals are concerning.

Completion

The submitted build is functional end-to-end: users can complete the assessment, receive a recommendation, see the score and reasoning, and follow an action plan. The public demo video shows multiple real application states, including repair, reuse/donation, and the safety override.

What we learned

The biggest learning was that sustainability software must avoid fake precision. Environmental impact is complex, so ReLoop explicitly separates practical decision support from verified lifecycle science. We also learned that the safest product behavior sometimes means overriding the most convenient recommendation.

Built during NextStep Hacks 2026

This standalone ReLoop implementation was initialized and authored on September 10, 2026, inside the hackathon build window. During the hackathon we built the responsive interface, browser-only assessment logic, circularity scoring, safety-first rules, action-plan generation, illustrative indicators/disclaimers, production server, health endpoint, Railway deployment, public code branch, and demo video.

This submission does not claim unrelated earlier prototypes as work completed during the hackathon.

What's next

The strongest next additions would be verified local repair/reuse/recycling directories, country-specific disposal guidance, evidence-backed lifecycle datasets, device-category repairability data, and optional integrations with municipalities or circular-economy organizations.
