Frequently Asked Questions



Should I rinse the packaging before disposing of them in the blue PMD bag?

In principle, you do not need to wash or rinse the packaging. However, it should be empty. When you have used up or emptied the contents, you can sort the packaging without having to rinse or clean it.

Can I leave the caps on the plastic bottles and flasks?

You may leave the caps on the plastic bottles and flasks in the blue PMD bag. They are also recycled. 

Why is packaging that contained toxic or hazardous products not allowed in the blue PMD bag?

Packaging that contained toxic products, drain cleaners, toilet descaling products, engine oil or other hazardous products such as varnish, paint, solvents, acids, pesticides, herbicides and insecticides may be hazardous for the employees of sorting and recycling centers. That is why this type of packaging needs to be processed individually. It should always be sorted with Small Hazardous Waste (Klein Gevaarlijk Afval – KGA or Déchets Spéciaux des Ménages – DSM). Check with your municipality or intermunicipal company to find out how it is collected in your municipality.

What does the Green Dot logo mean?

The Green Dot logo is not a sorting instruction. It does not indicate whether the packaging is allowed in the blue PMD bag. The Green Dot Logo is simply there to tell you that the company that markets the product is financially supporting the Belgian system of selective collection and recycling, not that the packaging on which it appears can be recycled or is made out of recycled materials.

If you want to find out whether your packaging is allowed in the blue PMD bag, we recommend checking the sorting rules for PMD. In the case of plastic packaging, only plastic bottles and flasks are allowed in the blue PMD bag

Why am I not allowed to attach bottles, flasks or other containers to the outside of the blue PMD bag?

The blue PMD bags are automatically opened upon entry in the sorting centers and sorted as a separate waste fraction. Packaging that is attached to the outside of the bag is transported along with the bags and therefore ends up in the wrong waste stream

What if my blue PMD bag is rejected with a red sticker?

The collectors are charged with visually checking the PMD bags that are put out in the street. When these bags contain waste that does not belong in the blue PMD bag, the collectors are required to leave them behind. In that case the collectors apply a red sticker to the bag. You must remove the incorrectly sorted items from the bag, tear off the front of the sticker and put the PMD bag out the next time PMD waste is collected. The procedure is similar for paper-cardboard. If you do not remove the rejected bag from the street, you risk being fined for littering. Check the PMD sorting rules to find out what you did wrong.


Are caps and lids allowed in the glass bins?

The caps and lids of bottles, flasks and jars are made of a variety of materials, including plastic, metal and cork. They can seriously contaminate the recycling process, which is why they are not allowed in the glass bins. Metal lids and caps should be disposed of in the PMD bag. Caps and lids of other materials should be disposed of in your residual waste bag or at the container park.

What about the labels on the glass bottles, flasks and jars?

Labels are automatically removed and disposed of during the waste treatment process and are not a problem.

Why is it important to sort glass correctly?

The better we sort, the more efficient the recycling process becomes and the higher the quality of the recycled materials will be. This definitely applies to glass. That is why coloured glass needs to be separated from white glass at the glass collection sites. Only white glass can be recycled into new white glass. 

Stoneware, earthenware, ceramics and porcelain are not allowed in the glass bins. The same applies to heat-resistant glass, which is used in oven and microwave dishes and ceramic cookware. The melting temperature of these materials is far higher than that of ordinary glass. As a result, unmelted shards may end up in the bottles that are made of these recycled materials, which become unusable as a result.


Why are soiled and greasy paper, cling film and wallpaper not allowed in the selective collection of paper-cardboard?

They contain substances including cellophane and glue that have a negative influence on the recycling process of paper. Fibers that are too heavily polluted disrupt the recycling process and undermine the quality of the recycled paper. Always dispose of them with residual waste or at your container park.

Why should I always remove the plastic film around advertising brochures and magazines?

The plastic substantially pollutes the recycling process of paper-cardboard. Always dispose of the plastic film with your residual waste or at your container park.
