Lego has unveiled its first bricks made from recycled plastic bottles and ( 11 ) that it hopes to include the pieces in sets within two years. The prototype 4x2 bricks have been made from PET plastic from ( 12 ) bottles with additives to give them the strength of standard Lego parts, and are the result of three years of ( 13 ) with 250 variations of materials. It has already ( 14 ) plans to remove single-use plastic from boxes, and since 2018 has been ( 15 ) parts from bio-polyethylene (bio-PE), made from sustainably sourced sugarcane. These parts are bendy pieces, such as trees, leaves and accessories for figurines. Tim Brooks, vice-president for environmental ( 16 ) at Lego Group, said the biggest challenge was "rethinking and innovating new materials that are as ( 17 ), strong and high (18) as our existing bricks and fit with Lego elements made over the past 60 years".
