For over a Decade its been a European legal requirement that vehicles be at least 80% recycled.

Plastics, fabrics and trim parts are increasingly being made from recycled and recyclable materials. Composits used for door cards and soundproofing by Mercedes BMW Ford etc are made from Hemp products.. turbine blades use Hemp Hurd/ pith in place of balsa.

The amount of composite boats scrapped every year in Australia would fill something like 6…8 stadiums.
America and Canada alone account for over half of the words boat market and disposal.

The big issue is the energy and resources consumed and if the resources can be recovered and reused.
Also the harmfulness of the materials used in manufacture use and disposal.
Micro plastics and nano plastics combined with the forever chemicals they are made from or contain are fundamentally life threatening …Already a Scientific Fact .
Causing premature births reduced fertility, cancers and a whole battery of clinical conditions.

If you want a boat you need to think about what its made from and how its going to have to adapt to the changing legislative and ethical frame works.

Personally i would like to see Glass dropped and basalt or Flax, hemp or bamboo used even chemically modified engineered wood worked into boat building … that way you lock up carbon for the life of the boat..

As for recycling by manufacturer .. this is already a thing with Windelo …they offer to buy back a yatch to recover the Basalt fiber.

Natural and artificial enzymes are making huge inroads into potential recycling pathways.

Remember burning fossil fuels and plastics has got us into this mess. The Earth took all that surplus Carbon out of circulation millions of years ago and buried it. Otherwise its doubtful we or countless other life forms would even exist.

We still need plastics but we have to vastly reduce the amount and become a lot more careful about what we use and do with them. Unless you want to spend more and more time and money unblocking engine intakes filtering water and air.. and untangling props and rudders and swimming in a sea of plastics chemicals and effluent.
The laws are already changing all over the world. Like the weather🌪️⚡🌀 🌊patterns and sea levels 🏝️and the species above and below the 🌅🧙‍♂️.

The most carbon emissions in the creation of a boat are sunk costs dealing with the production. Once it is built, it should be used until there's no economical life left. Then it'll be disposed of in a landfill.

Unless Jenneau and Arkema are committing to buy back the boat and have made infrastructure to emission free reheat the crushed hull to 400 degrees, then this "sustainable recycle" claim is just theoretical. Like glass – recyclable in major economies and continental infrastructure; but absolutely not recycled in islands where economic and population density doesn't support glass bottling plants.
