FAQ Frequently Asked Questions


Who can put on the site in plastic and waste products?

At this moment, in the project the choice was made to give access for posting plastics only to plastic converters that have a membership with a branch association.  The reason for this is to prevent abuse of the website. The administrator of the website, Delft University of Technology, reserves the right to remove posted plastics, if it appears that the posting is not plastic, does not comply with general rules, legislation and generally accepted good behaviour and social norms.


What materials can be posted?

The materials that can be posted are plastic by-products and rest materials. Examples are off-spec products, cutting and sawing residues, mold residue and small batches of  granules.


How much does posting a batch of plastics cost?

Posting plastics is FOR FREE. This website is part of the Plastics Re-use and Recycling Platform under the Climate KIC CMA programme. The project will run at least to the end of 2014. The website is property of the TU Delft. Branch organisations as the GKV , NRK en Federplast are consulted on this project and the website.


How can I post a batch of plastics?

You can post any batch of plastics (let over granulate, cutting rests, off-spec products etc) by

  • posting a photo of the batch,
  • a pdf of the specifications, MSDS-sheets of EPD's (European Product Declaration) of the plastic manufacturer,
  • and/or the following data:
    • your company name, contact person, telephone number, e-mail adress
    • amount of plastics
    • description of packaging of the plastics
    • technical data as colour, filling, melting point etc.

You don’t have to post photo’s, pdf’s etc., or even your contact information, because an interested party can contact you via the textbox. However: the more information you post, the higher the change you will have an interested party.

What are by-products and when is a rest material waste?

By-products are according to article 5 first paragraph of the European directive 2008/98/EC (link http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2008:312:0003:0030:en:PDF ) on waste and repealing certain Directives “A substance or object, resulting from a production process, the primary aim of which is not the production of that item, may be regarded as not being waste referred to in point (1) of Article 3 (‘waste’ means any substance or object which the holder discards or intends or is required to discard ) but as being a by-product only if the following conditions are met” :

  • further use of the substance or object is certain;
  • the substance or object can be used directly without any further processing other than normal industrial practice;
  • the substance or object is produced as an integral part of a production process; and
  • further use is lawful, i.e. the substance or object fulfils all relevant product, environmental and health protection requirements for the specific use and will not lead to overall adverse environmental or human health impacts.

Note: All criteria must be met, there will be a by-product.


When does waste stop being waste?

Waste that meets the 'end of waste'-criteria has no longer the status of waste. This is the case when waste has undergone a recovery or recycling operation, and meets specific criteria. These criteria are to be set up by the European Commission. The Waste framework directions gives the conditions on which the European Commission has to base the specific criteria. These conditions are the result of case law. It involves the following conditions (Article 6 of the European directive 2008/98/EC):

  • the substance or object is commonly used for specific purposes;
  • a market or demand exists for such a substance or object;
  • the substance or object fulfils the technical requirements for the specific purposes and meets the existing legislation and standards applicable to products; and
  • the use of the substance or object will not lead to overall adverse environmental or human health impacts.


How do I save more on waste management costs?

It is quite possible that you had to get rid of rest materials  with the regular waste. Now you have found interested parties for your plastic by-products and rest-materials, your waste container may mostly be only half full or almost empty when emptied by your waste management company. If you measure how full your bin is just before it is emptied, the container might indeed be half full or almost empty. In this case you might consider renting a small dumpster or less frequent emptying. This saves in waste costs.
