  • Q2
    What is, according to Prof. Peter Rem, an important reason why polymer manufacturers are not interested in creating a ‘perfect’, infinitely recyclable polymer? Select the correct answer.
    Because of the higher costs associated with developing such a polymer.
    Because they have not integrated recycling into their processes, so the competition with plastics recyclers would increase.
    Because there is little demand from brands and consumers for recyclable packaging.
    Because they can no longer use additives to improve, amongst other things, the transparency or colour of the packaging.

  • Q3
    Prof. Peter Rem talks about a plastics separation technology that uses a nano liquid. This magnetic density separation uses a magnet to manipulate a flotation bath filled with a ferromagnetic fluid in order to create a density ‘’gradient’’ within it. This means that plastic particles with different densities can be collected from the bath at multiple levels. What would a recycling company that uses ‘traditional’ sink-float density separation technology need to do to achieve the same effect? Select the correct answer.
    Question Image
    Increase the size of the flotation bath that is used.
    Increase the size of the particles that are used.
    Increase the density of the liquid that is used.
    Increase the number of different flotation baths that are used.

  • Q4
    Supermarkets often use black plastic trays to make their produce look more appealing. Similarly, personal care brands sometimes use dark colored plastics to give products targeted at men a more masculine look. These considerations pose a direct challenge for sorting with Near Infrared Spectroscopy. Why? Select the correct answer.
    Because it is difficult to turn dark coloured waste into light coloured new material.
    Because these plastics have similar densities.
    Because there is less demand for dark coloured recycled material.
    Because dark plastic flakes absorb (nearly all) light.

  • Q5
    Robert Seegers discusses the design of a Coca-Cola bottle. He mentions a few aspects of the bottle with respect to recyclability. Earlier in the lecture considerations and design guidelines for recyclable packaging were mentioned. Which of the following statements about the incorporation of these considerations in the design of the cola bottle is not true?
    The material composition and end-of-life options are communicated.
    Recycled materials are used in the bottle.
    One single material is used: all parts are made from plastic.
    Multiple materials are used, but they are easily separable.
