Smart Waste Collection

  1. Problem: Waste Management. There is a lack of efficiency and transparency in waste management. Not knowing how full the bins are make it difficult to maximize efficiency. When the bins aren’t full when collected, it leads to additional emissions and extra trips. When the bins have been full before the scheduled pick up, it causes social problems such as overflow of waste on the streets.
  2. Summary:
    • Bratislava is implementing a large-scale smart waste digitalization program using Sensoneo. This will realize savings on waste collection related to truck mileage, emissions, and prevention of damages related to overfilled containers. 
    • Will be implemented in stages until April 2022
    • Project includes 
      1. digitalization of 85,000 containers and installation of 1,753 Sensoneo sensors to monitor all containers for glass waste and underground bins across the city
      2. Will also deploy 92 Sensoneo WatchDog devices on all waste collection vehicles to automatically digitalize the waste collection process and automatically verify pick-ups
      3. Flexible waste collection powered by Sensoneo’s Route Optimization and the testing of prototypes facilitating the introduction of “pay-as-you-sort“ models and recognizing fill-levels of containers during pick-up.
    • Glass waste is particularly troublesome due to its irregular filling cycle. Using Sensoneo’s technology, the city can avoid unnecessary pickups. 
  3.  Stakeholders
    • City’s waste management company
    • Waste collection fleet operator
    • Waste collection drivers
    • Waste dumpster location that receive the waste
  4. Steps
    • Digitalize the location of 85,000 containers on the software
    • Install the necessary sensors on the containers for glass
    • Install the Watchdog devices on the waste collection vehicles


One thought on “Smart Waste Collection

  1. Hi Jiaxin! Great article. I absolutely love the idea of this technology. This was the type of the technology that my group tried to advocate for in the rats scenario!

    There are a few companies already implementing this type of technology, such as Nordsense Inc. ( which I believe is a Danish waste management company, focused on smart bin technology. According to Nordsense, 90% of the world’s waste is collected at the wrong time! If waste collection is ‘too late’ it may result in illegal dumping and additional costs for cleaning/collection, but if waste collection is ‘too early’ a government could be wasting time, resources, and money. I wonder who has access to the data- because if it is publicly available data, it may encourage illegal dumping, yet, at the same time, it may improve the cleanliness of communities (people will know where to dispose their waste). I also wonder whether this technology can be scalable on a residential level, or would it not make sense logistically.
