QR-based inventory system for a hazardous waste company
An inventory system for a hazardous waste management company that logs each waste item by QR code and traces it from collection to final disposal.
About the client
The client is a hazardous waste management company. It collects, processes and disposes of industrial and chemical waste.
The challenge
Manual tracking of hazardous waste created safety risks and compliance issues for the company.
- Errors in waste records
- No real-time view of inventory levels or locations
- Time-consuming data entry and record keeping
What we built
The inventory system runs on a PostgreSQL database and uses a QR code to identify every waste item.
Stock monitoring and alerts
Stock levels are monitored automatically, with alerts, and inventory is managed by location.
Collection-to-disposal tracing
Each item can be traced from collection through to final disposal.
Capacity and disposal forecasts
AI-based forecasting supports planning for storage capacity and scheduling disposals.
The results
The company has replaced manual waste tracking with a custom inventory system.
- Items are logged by scan, so fewer records need correcting
- Stock levels and storage locations can be checked at any moment
- Staff spend less time typing in and maintaining records
