Bratislava launches large-scale smart waste management deployment

Bratislava, the capital of Slovakia, in cooperation with the technology company Sensoneo, has announced the launch of a project targeted at waste digitalization and efficient waste collection. The project is supported by a grant from the European Innovation Council, which Sensoneo received in the summer of 2020 for the large-scale deployment of its solution to demonstrate its environmental and economic benefits. The project includes several stages that will be implemented continuously until April 2022. The city expects savings on waste collection-related mileage and emissions as well as the possibility for early intervention in the case of overfilled containers.

For the citizens of Bratislava, this would mean cleaner public spaces and more efficient waste collection services, “ explained Katarína Rajčanová, city spokeswoman.

Bratislava is digitalizing containers by using Sensoneo RFID tags, installing smart sensors into the bins, and deploying a WatchDog device on waste trucks to digitalize all activities done during the collection.

Digitalization of waste infrastructure is in line with the city’s Strategy for Municipal Waste  Management with the aim of transitioning to a circular economy for the years  2021 – 2026.

Our goal is to have exact data on the volume of waste that residents produce. These data would be then be reflected in statistics at the taxpayer level. Each collection container or bag in the city will be tagged and its dumping will be recorded using the waste collection technology.“ Ivana Maleš, co-author of the city document

The project also includes testing of Sensoneo’s prototypes facilitating the introduction of „Pay as you sort“ models and recognizing fill levels of containers during the pick-up.

More efficient waste collection services

Savings on waste collection related mileage and emissions

Considering the scope, size and technologies applied, the project represents the first-of-its-kind deployment on a global level. The use of smart technologies in the management and collection of waste is in its early stages as of yet – even the world’s most well-known capitals are piloting the technologies. At the moment, there is no reference from a large-scale deployment in the world that provides evidence of the benefits covering such a large scope – infrastructure management, process digitization, and dynamic collection.

Cooperation with the Slovak capital is a logical and natural outcome, considering the focus of our company. We would like to thank the city of Bratislava and its waste management company OLO for their trust and active interest in new technologies with the power to make waste management and collection more efficient and the least disturbing to the environment, “ Tomáš Vincze, Project Manager at Sensoneo

Digitalization of 85 000 bins

85 000 containers tagged and digitalized with RFID tags with QR codes in Bratislava city.

To identify, track and trace the bins, the city will use Sensoneo’s RFID tags with unique codes that will be permanently installed on every bin. The actual digitalization will be performed using Sensoneo’s Inventory digitalization App. The app allows one-click identification with the RFID code of pre-registered inventories as well as the easy assignment of new stands and bins with detailed specifications, GPS positions, and accessibility details. Additional features include notifications on asset misplacement data.

Containers for glass and semi-underground containers present the highest potential for savings – in terms of fuel and mileage as well as in terms of time and emissions. Glass waste is particularly troublesome due to its irregular filling cycle, and Sensoneo’s real-time sensors offer invaluable time savings by identifying when the collection is required, thereby eliminating unnecessary pickups and ensuring that bins won’t sit overfilled. To empty the underground bins, there is a need for a vehicle with a hydraulic arm. This means extra costs and, in many cases, an unnecessary burden for traffic congestion as the emptying takes about 6-7 minutes.

This knowledge motivated the city to select 1753 bins to be monitored with Sensoneo sensors. Besides the actual waste production monitoring, the data will be used for the automated optimization of waste collection routes targeting the shortest mileage possible and maximized capacity utilization of the vehicles on return to the depot. The routes will be available to drivers in Sensoneo’s Driver Navigation app, which is designed for the specific needs of waste collection vehicles. This approach will also facilitate the easy onboarding of new drivers.

Transparent waste streams
and automatic service verification

92 collection trucks with Sensoneo WatchDog device.

The lack of efficiency and transparency are some of the biggest challenges in waste management. The city of Bratislava will deploy Sensoneo’s service-monitoring tool: WatchDog on all vehicles to test the functionality of automatic identification of bins and bags authorized for waste collection, automatic verification of pick-up of each bin, and a precise recording of all the routes made. The city’s waste management company OLO will also use Sensoneo’s Fleet Management to manage daily operations related to vehicles and routes.

Operators will be given a detailed and complete overview of all the operations made in the field and in the depot including the ability to receive real-time updates on the ongoing routes and locations of the trucks on the map. The tool also includes the Garage Dashboard, Incident reports, and detailed statistics including driving patterns.
