01 // The Story

Solving the sorting
bottleneck.

Waste segregation in India is fundamentally broken. Mixed waste at the source results in contaminated landfills, rendering massive amounts of potentially recyclable materials completely useless. We wanted to build a system that solves segregation at the root.

Recylo runs on a Raspberry Pi 5, performing local Edge AI inference on RGB camera frames to classify waste within milliseconds. It requires no cloud API calls for inference, ensuring zero latency and high privacy.

Once classified, dual pan-tilt servo motors physically actuate to route the waste into the appropriate bin. Simultaneously, load cells measure the weight of the bin, piping live telemetry data directly to a Supabase cloud backend to inform municipal routing.

1

Visual Capture

Camera captures RGB frames of the inserted waste item instantly.

2

Edge Inference

ONNX-based CNN model running on Pi 5 classifies into 4 categories.

3

Physical Routing

Servo motors articulate the chute to deposit the item in the correct bin.

4

Cloud Telemetry

Load cells sync exact fill-levels to the Municipal admin portal.

02 // The Execution

Four compartments.
Zero confusion.

Watch the system visually identify items and physically route them using the pan-tilt servo mechanism.

Wet

Organic food scraps, peels, and biodegradable materials routed directly for composting.

Dry

Paper, cardboard, wrappers, and clean plastics set aside for standard recycling lines.

Metal

Cans, foils, and metallic items separated to prevent contamination of organic matter.

Hazardous

Batteries and e-waste isolated strictly for safe and secure disposal.

03 // Tech Stack

The Engine.

A unified architecture spanning from bare-metal hardware to cloud dashboards.

Raspberry Pi 5

The central compute unit running ONNX inference and handling GPIO logic.

React & TypeScript

A unified frontend monorepo housing the Citizen, Driver, and Admin portals.
