Garbage trucks run to the paper container in Dejvická Street five times a week. Thanks to the sensors inside the containers, the city staff knows how often to export the paper.
“The sensor is visible in the middle part of the vessel to measure the entire volume, and six to eight times a day it sends a beam that flies downwards,” described the operator of the ICT Department of Innovative and Pilot Projects Smart City Ondřej Šárovec.
It bounces off the waste and evaluates the fullness of the container according to the time sensor. So far, Prague has tried it in four hundred and sixty places, and in some of them it has already adjusted the frequency of pickups. “Already during that pilot operation, the frequency changed and savings were generated. Of course, the covid also had an impact on that. For example, there was a more vigorous filling of plastics, because people started to use disposable packaging more, “said Šárovec.
It should have sensors for 6,000 underground containers by the end of next year. The city will run for thirty crowns this year. However, due to higher energy and transport prices, the municipality is preparing a further increase in the fee.
“There is a real threat of an increase, especially where there are the big containers and frequent collection, and that is in the housing estates,” said Petr Hlubuček, Deputy Mayor and Councilor for the Environment, Infrastructure and Equipment (STAN).
The increase should also motivate greater sorting and use of brown bins for bio-waste. For example, in the Prague Market, where they produce up to fifteen hundred liters every week, a large-volume composter processes new vegetable and fruit residues.
