offcuts are produced to make a viable feedstock for a recycling company.
Keep a small stock of alternative materials
‘If you don’t have them on site, you’ll never start using them,’ Morgan says. Munro points out that a lot of parts are made from carbon simply because it is lying around, when a more sustainable – and cheaper – material would do just as well.
Sustainability can be good for business
CDK Technologies has saved about €8,000 per build by improving its recycling. ‘Four years ago we set up a garbage separation system with coloured bins,’ says deputy general manager Yann Dollo. ‘It was a suggestion from the guys in the shed, not a command from management. We’re spending less on refuse collection, which was a surprise. We’ve reduced the volume of waste and we’re reusing part of it.’ Gaining a reputation for recycling also helped the yard win a contract to build 80m carbon masts for a new fleet of sailing freighters. A key initiative setup between CDK Technologies and one of their major suppliers highlights the value created by collaboration. They stored cardboard packaging on site, and then sent it back as a full shipment to the supplier, which saved CDK more than €4,000 in waste management, avoiding the purchase of packaging from the supplier, and avoiding one metric ton of greenhouse gas emissions. This is the net result, and takes into account the impact of return shipment, highlighting
Top: every part of Malama’s build was meticulously documented to compile an accurate and comprehen- sive lifecycle assessment which it’s hoped will
inform many of the future rule changes in the Imoca class. Above: 11th Hour Racing Team’s build manager Wade Morgan is the crucial inter- face between the sailors and boatbuilders. Right:a significant carbon foot- print reduction was achieved by using bio- based Dyneema
that some of the best solutions are both economically and environmentally beneficial.
Class rules have to change ‘Without incentives to change, the primary design and build criteria will always be performance ,’ Foxall says. ‘There is an unavoidable requirement for classes and event organisers to take the lead and set strong policy and place sustainability within the design spec. Sailors are inherently innovative, by placing sustainability within the design brief we unlock this capacity and give our designers and builders permission to find the best sustainable solutions.
‘Lifecycle assessment is just a measurement tool, the objective is to highlight the hotspots and then do something about them. Future builds need to be done with a carbon cap, leaving enough scope for designers and builders to avoid creating an IOR-type situation with secondary effects. Finally, setting an internal price on greenhouse emissions can create a mechanism which supports good policy. Teams initiating new builds could be charged as “polluter pays”, reuse of boats and their components would be incentivised as zero impact - zero cost thereby supporting smaller teams and
budgets, and the funds generated would support reduction programs such as recycling and coordinating better boatbuilding,’ Foxall explains. ‘A key topic within the Imoca class are the foils, says Le Pen. ‘At approximately 100 tC02e per set, [+/-20 per cent the overall impact of a boat launched and ready to sail], foils also represent a large part of the waste, man hours and resources within an Imoca team campaign. Again, without a check-balance on performance, external secondary impacts have skyrocketed, and while most people would still like to keep Imocas “flying” we need to do this with a more sustainable approach within the class rule.’
Some positive changes are already under way, as CDK’s Ollivier points out: ‘Until recently, the culture in the industry was that you sourced and used everything you wanted without thinking about it, even if the cost was very high. It was normal to transport one piece of Nomex all the way through Europe on a truck just to make a small part because the naval architect said it would save a hundred grams. Now that is unthinkable.’
