The drastic reduction in the use of plastic during sport competitions must be a goal of the organisers.
The solution introduced in the London Marathon seems effective. In the 2018 edition, 919,000 plastic bottles were used, the use of which was reduced to 700,000 in 2019. These will be reused to build new plastic bottles.
200,000 bottles have been replaced with the use of bubbles containing water or mineral salts that could be ingested by runners consisting of a totally edible membrane derived from a natural algae. The casing can also be thrown away and biodegrades in 6 weeks instead of 450 years, as is the case with plastic. It is produced by the company Skipping Rocks Lab
