Smarter and more efficient recycling yards with Revolution Pi

Digital Waste Management – recycling center

Challenge

Recycling centers face diverse challenges: overcrowding, long wait times, and unauthorized waste disposal strain operations. A flexible, cost-effective solution was required to integrate precise weighing, secure access control, and digital management—ensuring maximum user-friendliness for citizens and staff.

Gassner Wiege- und Messtechnik GmbH from Austria specializes in innovative waste management solutions, including access systems, scales, and smart waste facilities for municipalities and industries.

Solution

Gassner developed a sophisticated digital system based on Revolution Pi. The solution combines intelligent access control via RFID or mobile app with precise weighing technology and flexible payment options. A key feature is real-time availability updates for recycling centers accessible via smartphone.
