Lego Investigate Recycled Plastic Bricks

Plastic from discarded drinks bottles are being trialled to make Lego bricks. The company Lego are committed and hopeful that the recycled bricks will be released by 2030. They tested over 250 variations of PET plastic and developed a prototype solution using the recycled bottles. This is part of Lego's journey to making products from sustainable sources. Lego are working on ensuring that the new product will fit with any of the Lego elements made over the last 60 years.

Lego's Relay Programme 

Lego currently have a Lego Replay programme which encourages owners of Lego bricks that they don’t use any more to pass them on to ensure they have a new creative life. The programme is currently in practice in the US and Canada and the company hope to expand to other countries soon but owners can continue to pass on to friends or family or donate to local charity shops. You can find out more about Lego donations on the Lego site here https://www.lego.com/en-gb/aboutus/replay

PET Plastic

The bottles sourced for Lego’s recycled bricks contain PET plastic and must be ground down and cleaned to begin with, after which a strengthening process is applied to make the bricks suitable. One plastic bottle can make ten of the 2 x 4 Lego bricks! The bricks are then moulded, coloured and tested for quality and performance.

Lab tests at different temperatures 

Lego perform quite a number of lab tests including testing the bricks at different temperatures to determine if the bricks will hold together. The higher the temperature - the bricks hold could be compromised. Checking the durability of the bricks is crucial before Lego can analyse production set ups.



Techris Systems can provide a number of thermometers that can be used during production processes and laboratory tests that can provide accurate, fast temperature recordings across a wide range of temperatures.
