Our Story
In the world of environmental accounting there are a few debates that refuse to go away: comparisons between washing reusable nappies instead of disposing of them – or refilling glass bottles instead of recycling them. Similar questions have been posed over the efficiency of retreading old tyres instead of the manufacture of new ones.
The main arguments revolve around the efficiency of collecting old tyres and their subsequent performance profiles. At BFF we like to apply our accounting expertise to tackle such issues, so we welcomed a commission from the Centre for Remanufacturing and Reuse to compare the carbon footprint of a new and a retread 17.5-inch tyre for use by light commercial vehicles
The headline results show that the manufacture of a 17.5-inch new tyre produces 86.9 kg CO2 emissions compared to 60.5 kg CO2 for an equivalent retread tyre, a saving of 30 percent. The full report is available from the Centre, and has been picked up by US car industry publication Motor Age. In the article the Retread Manufacturers Association director David Wilson welcomes the results saying: “…an independent report has validated the retreading industry’s environmental credentials.” BFF will also be watching out for responses to our study from primary manufacturers.
