A green sport, but a dirty industry
Indoor climbing has its roots in nature, and this is reflected in the ecological awareness of even the most urban climbers. Despite this, climbing holds are made from thermosetting plastic, which has a horrendous environmental impact.
To give you an idea, 1 kg of polyurethane holds emits 11.84 kg of C02. In other words, one hold = a 50 to 100 km journey in a petrol-driven car. In addition, there is currently no process for disposing of them. For the most part, they are thrown in the skip and either buried or incinerated.
« We estimate that 7 million end-of-life holds are thrown away every year. »
