Benchmark municipalities


Stichting OPEN benchmark reports the volumes of waste electrical and electronic equipment (WEEE) that have been disposed of via municipal collection locations. This benchmark provides municipalities with insight into the volumes of WEEE collected per six months. This means that every municipality can immediately see how well their collection is going.

We send the benchmark report to waste policy officers and recycling center managers. For this purpose we use the email addresses known to us. However, we do not have the correct contact information for all municipalities and all relevant employees. If you work for an umbrella organization that provides waste collection for several municipalities, we ask you to pay extra attention to this: so share the benchmark with the right employees of your organization.

Data accountability for collection data

The benchmark has been compiled with the utmost care. The calculation used weighing data as well as conversion weights and distribution keys. As a result, the weights in the benchmark may differ from the invoice proposals. The weights described on the invoice proposals are the weights that have been released from a specific collection point, these weights are and will always remain leading for the reimbursement. In some cases, these weights are divided in the benchmark using distribution keys across several municipalities. This is further explained under the heading ‘distribution keys’. Both types of data have been used to provide the most accurate insight possible into the quantities collected. No rights can be derived from the content of this overview. The OPEN Foundation is not responsible for any inaccuracies in the overview and therefore accepts no liability whatsoever for any damage that may result from its use. Furthermore, the weights from the benchmark can never serve as evidence of differences between the weights from the benchmark and the weights from the invoice proposals, nor can they give rise to adjustments thereof.

A number of specific elements of the benchmark are highlighted below.

Collection per inhabitant

Collection per inhabitant is central to the benchmark. This is the indicator for collection that can be easily compared between municipalities. The municipality with the highest collection per inhabitant will therefore end up in first place. The municipality with the lowest collection per inhabitant is in last place.

Collection points within your municipalities

The collection from recycling centers, thrift stores and municipal yards within the municipal boundaries is included in the benchmark. Shops such as electronics stores and hardware stores with a Wecycle collection method are not included in the benchmark. This selection was deliberately chosen for two reasons:

  • Because shops are outside the sphere of influence of a municipality and can have a strong influence on the outcome of a benchmark. A distribution center with a high collection within the municipal boundaries but a catchment area far beyond can strongly distort the benchmark;
  • Thrift stores that are not included in the municipal agreement are also included in determining the benchmark. This was chosen because the cooperation between thrift stores and recycling centers is intensive in the Netherlands. Through Service Agreements, a collection service of WEEE from municipal residents is often outsourced to thrift stores. This benchmark therefore makes no distinction between different types of thrift stores. It is assumed that all WEEE from thrift stores is under the influence of the municipality.

When Door-to-Door routes with separately collected WEEE are registered and are known to us, these are also included in the collection figures. The following type of collection is in any case not included in the benchmark:

  • The retail collection from companies such as electronics stores.
  • The collection from installers and kitchen shops.
  • The fine-grained collection from supermarkets, garden centers and hardware stores.
  • The collection of metal recyclers.
Collection data

The collection data is based on weighing of the material removed from the acceptor. In the case of recycling centers, this is almost always the sorting center where the WEEE containers are registered. The weighing figures have not been corrected for contamination such as residual waste or cardboard that came with the WEEE. When fine-grained collection takes place, it may also happen that individual devices or containers are converted to weights using conversion weights. This only concerns a small part of the collection.

Weight distribution keys

The collected weights are registered per collection point (e.g. recycling centers). However, some recycling centers are accessible to residents from different municipalities. In this case we use distribution keys to distribute the registered volumes among the municipalities involved. We have coordinated these distribution keys with all municipalities. These are sometimes based on visitor numbers, the distribution of inhabitants per municipalities or other estimates. If no response has been received from your municipalities, we have made an estimate of this distribution key, based on the residents of the municipalities that are allowed to donate to the relevant recycling center.

Residents CBS

The collection is expressed in collection per inhabitant. This number is easy to compare between the different municipalities. For this we use the collection and population numbers per municipality, as published by Statistics Netherlands.

Avoided CO2 emissions through the correct processing of WEEE

When WEEE is processed correctly, this results in fewer greenhouse gases. The amount of greenhouse gases avoided can be calculated. By monitoring the avoided carbon dioxide (CO2) emissions, trends in environmental benefits can be discovered. The OPEN Foundation has had research conducted into this (Avoided CO2 emissions through e-waste processing). Based on this research, it has been calculated how much CO2 is saved per fraction of WEEE (Solar panels are not included in this study).

WEEE in residual waste

The WEEE in residual waste is calculated by multiplying the residual waste of a municipality by the average percentage of WEEE in residual waste. The percentage of WEEE in residual waste is measured in sorting analyzes by Statistics Netherlands. This benchmark is based on the CBS sorting analysis from 2022. This is the most recently published sorting analysis. The percentage of WEEE in residual waste has been set at 1.2%. In the benchmark, this percentage is generic for the whole of the Netherlands. Therefore, no use was made of sorting analyzes specific to each municipality.

CBS Statline annually publishes the amount of residual waste per municipality. This benchmark used the most recent data. If no data are available from Statistics Netherlands on the amount of residual waste in a municipality, an average of all municipalities is used.

WEEE in PMD

The WEEE in PMD is calculated by multiplying the amount of PMD of a municipality by the average percentage of WEEE in PMD. PMD is maintained per municipality by Statistics Netherlands. WEEE in PMD is tracked by our partners in composition analyses. The benchmark uses a generic percentage for the whole of the Netherlands. This has been set at 0.59% for 2023. There is therefore no percentage differentiated per municipality. If no PMD collection data is available from Statistics Netherlands, this is shown in the benchmark as “Not applicable”. This differs from the method for residual waste, because it can also happen that a municipality does not apply source separation and therefore does not have a separate PMD flow.

Compensation

The compensation included in the benchmark is the municipal compensation for 2024. This compensation is EUR 108.88 per tonne. Municipalities receive this compensation for the actions performed at the recycling centers when collecting WEEE.
