In a new case study, we’re delighted to highlight Rotterdam’s progress toward more efficient waste collection. The second largest city in the Netherlands and one of the world’s busiest container ports, Rotterdam like many communities, needs to manage growing waste levels efficiently and effectively.
Stadsbeheer Rotterdam sought innovative solutions to help drive efficiencies and utilise the city’s waste budget more wisely. An eager participant in the circular economy, the city’s leaders believe clean streets are key in fostering positive attitudes in their community, where they speak proudly of only 1% of waste ending up in landfills.
For the population of 620,000 there are 6,500 underground waste containers for residential waste with a further 650 for paper and around the same for glass. 70% of the cities inhabitants live in multi-storey apartment complexes with communal waste sites, which has eliminated the need for thousands of individual household bins. It has however, made keeping these emptied reliably a critical activity for the city.
Rotterdam has worked hard to optimise the waste value chain, from the location and number of receptacles, to ensuring containers always have space for citizens to use. Until recently this had always been done using static collection routes but the city had recognised this as a point of inefficiency. After trialling manual fill level monitoring, Stadsbeheer Rotterdam set Enevo and our partner, TWS a target of increasing efficiency by 20%.
The city’s waste management team had identified that they needed to know the fills levels of bins more accurately and combine this with dynamic route planning. The manual work prior to the project provided a base line to test against and the city chose to pilot with paper and cardboard fraction waste.
We installed Enevo ONe sensors in 150 containers to continuously monitor fill levels, with the data being uploaded to Enevo’s cloud servers and visible to the project team. Fill level, rate of fill, location, temperature and obstruction detection were recorded for every bin.
The pilot area was serviced by a single operator collection truck, operating 5 days per week. Each waste container was 5 cubic metres and the Enevo “big data” analytics determined 70% fill as the optimum level to eliminate overflow.
Enevo’s Smart Plan dynamic route planning system collated all data from the sensors, compared fill rates to trends and predicted when each bin should be emptied. To do this the system analyses millions of possible collection options to provide the optimal route for each journey, maximise resource efficiencies, whilst minimising distance travelled and the possibility of overfills. Each days plan for collections is downloaded in advance to a tablet pc in the refuse truck for the driver to follow to collect the bins that most need emptying.
The Enevo trial easily beat the 20% target. By using the Enevo system, Rotterdam was able to collect the same volume of waste with a reduced number of weekly collections. This significant increase in productivity was matched by a rise in the mean fill levels of containers, saving time, fuel, service costs and emissions.
The Rotterdam pilot has demonstrated that by embracing technology and partnering with Enevo, a flexible waste monitoring, collection and recycling process can deliver significant returns for the city.
