Green Leader developed a web system for keeping control and traceability of the hazardous residues. The system incorporates a checklist application form onsite. The operator, through a smartphone, will scan a QR code unique to each residue container and will be asked for information and photographs once the service is done. After the form is completed, the georeferenced location will be updated and the status will be finished.
The application form can be worked online or offline. The information will be saved in a smart spreadsheet called smartsheet.
