presumably in that scenario - you'd then 'dry' the aluminium solution and throw the resulting back into smelters ? |

in the case of the topper where the hull is mainly the two monolithic injection mouldings splitting for recycling makes sense as the only 'mixed colour' part is the seam area which iirc has wire in it to aid the bonding process boats are not 'single use 'plastics - that's straws , (cheap) plastic cutlery, cheap plastic / foam takeaway containers , plastic cleaning product / toiletry / cosmetic packs etc etc etc |

In my youth I was briefly an industrial chemist. We were presented with (IIRC) a requirement to strip a nylon coating from aluminium zip fasteners to permit recoating where the original coating had failed QA. We didn't succeed in finding a formulation to do the job, and I wasn't allowed to send out my report which recommended dissolving the aluminium out of the nylon and starting again... |

Actually, the anodised surface is aluminium oxide with a bit of dye in it. Probably some oxides of whatever the aluminium is alloyed with, e.g. silicon, magnesium etc. Anodised ali is among the most favoured for recycling, it's less problem than paint, plastic coating, alochrom and most of the other surface treatments.

The anodic film created in anodising is 100% pure aluminium. Anodised aluminium can be recycled through simple re-melting without any intervening process. ... The recycling of composite panels is even more complex because of the extraction and destruction of the core material.

AIUI Aluminium, once it's been anodised, cannot be melted down and recycled...

The problem is, your end of life pico is probably 'end of life' because it's seen a lot of sunlight and gone brittle? That tends to mean it is degraded plastic and not directly recyclable, it has chemically changed, you cannot just melt it down and mould something new as you might with aluminium. You can use it to make something which demands very little strength from the plastic perhaps. This is why things made from 'recycled' plastic are usually crude and heavy, like park benches. It's borderline 'greenwashing' in some cases, more about storing the waste off the books than making an actual product.

Single use suggests 1 sail, then bin, like a cucumber plastic wrapper. Using a boat for 10 or even 20 years (or 5, maybe in a sailing school) would seem like good use compared to almost any other plastic product. If it can be turned into bricks, or pothole filler at the end of that, all the better.
As to why Topperand Laser went rotomould, it was because they kept on losing money on their racing boats, barring the main two. They probably got fed up the class associations, too! |
