Lego drops prototype blocks made of recycled plastic bottles as they “didn’t reduce carbon emissions”::Danish toy giant Lego said 2 years of experimentation with blocks made from recycled plastic bottles showed they “didn’t reduce carbon emissions.”

    Forgive my ignorance, but isn’t the point of reusing plastic to prevent or reduce plastic waste and contamination? Not necessarily carbon itself.

    Actually pretty amazing that they are willing to scrap it and keep researching instead of just going with it and saying “We did it! We did the sustainability thing! Now please resume your normal purchasing schedule.”

    Does that mean recycling PET doesn’t reduce carbon emissions in general, or is there something specific about Lego blocks that makes it less practical?

      They stated that the new mater lies would not live up to their requirements on longlivity and quality. Abs which is currently used is quite stable and can and is therefore be used for generations.

      The new materials would lead to faded and broken Lego bits after some years and degrade the brand perception. Since new stuff would need to be bought then this would be less CO2 efficient.

      For other PET products we usually do not have any longlivity requirements. Plastic bottles barely need to survive for a year and therefore the recycling process is still much better than producing new plastic.

      In short: It is better to produce 1kg of CO2 once every 30 years than 0.2kg of CO2 every 5 years.

      I am sure there is still some typical greenwashing in the calculations, but it makes sense to me that they do not want to reduce their quality standards.

        The article says the recycled plastic was able to meet their quality requirements, just not with any reduction in emissions. They’ve also tried many potential materials that didn’t meet their requirements, and presumably some of the other options could have reduced emissions at the expense of quality.
