recycling composite boat

Bon Fire ? 2000 degrees ??

The standard " burn off test" to separate resins from fiber is around 600 C degrees.

Best if you go to your school library and consult standard " ASTM D3171 - 09 "


This document outlines the methods used to heat or chemically dissolve the resin from a fiber reinforced structure.

the test is used by engineers to determine the resin to fiber content of a composite structure.

When recycling there would be no reason to destroy the fibers,only remove the resin .

Michael, they were talking about melting the glass.

 

Seems that the standard approach is to melt off the resin and reclaim the fibers. The aircraft and windturbine industry is already heavily invested.

Mark, Michael doesn't answer direct questions about his posts, though he often attempts to change the talking points in threads, to whatever he'd like to rant about. When directly questioned about this, he changes the subject. When asked to defend his positions, he uses the same tactics.

 

Par...you cant read. The original poster asked how to "recycle" a composite structure, not how to employ the Par technique of pulling the garboard and sinking it, nor how to burn it and destroy the structure. Read the link posted and learn something new. Address the original posters question.

 

And once again you've avoided answering questions about your own posts Michael. As was pointed out we were talking about something else, which you miss understood or attempted to divert (again), yes, possibly a side bar to the main discussion, but it was there none the less, nor less valid, well of course except by you.

The original question has been answered Michael, and composite structures are "recycled" in several ways. Just because you don't accept these ways or in your part of the world they just dump things in the "crystal clear Med" (making one wonder how bad the dumping actually is) and haven't any organizations to over see and/or regulate these practices, is frankly irrelevant to the conversation, if unfortunate. My contention all along is there isn't a big need that isn't being addressed in a reasonable way already.

Your problem is you're attempting to make a mountain out of a mole hill. I'll bet you any amount you like in the high volume tourist areas, there aren't any major eye sores of boats piled up on desolate shore lines. Yet in the small coastal towns just up the coast, where only the locals drink beer, there are. This isn't a problem Michael, it's modern society and the general "corporatism of society" as a whole. Most western societies have sold their souls to big business and industry interests. We've gotten lower prices for soap, soup and socks, while they get the prime real estate, poison our air, water and land with little worry that they'll be forced to stop. The longer we permit the "corporatism of society", the more and more small shops will be bought out by big interests and the more likely our social souls will be ruled by a board of directors and a CEO, who really don't care if the boats pile up in a little town up the coast, so long as they don't see them, the next time they have a vacation there. Now we're get back into the "you got to know what's going on" thing again.

 

What are you talking about ? There is a problem right now.... disposal of thousands and thousands of short lifespan plastic charter boats is upon us now. The farmers fields on this island are flooded with fiberglass hulks. .... Public landfills are overflowing and there is no additional space to dispose of huge chunks of debris. This small shipyard has 100 tons of waste composite material in its parking lot.

Production boat builders are pumping out new yachts as fast as they can mold them..Its incorrect that they are allowed to create a structure with absolutely no plan on how to dispose, recycle it when its life cycle is over.

This has nothing to do with Corporate socialism, CEO's, big business or any virtue, vice of Western Society.

This thread was started by a student who is interested in attacking this problem. To contribute to his and any interested readers knowledge it would be wise to stay on topic and contribute what you know concerning technology presently being employed to recover energy or any useful materials from discarded composite structure.

 

You have absolutely know idea how a market works, let alone the very realities of which you are denying. No manufactures are pumping out huge volumes of boats, everyone is stalled at their bare minimums currently and have been so for a couple of years. You really should try to keep up. No company will produce, let alone over produce without some reasonable assurance, their products will not become a glut on the market, driving prices through the floor, but then again any reasonably literate person would understand this.

If you don't think the world isn't run by well greased politicians then you're even more clueless then suspected. 90% of the grease comes from industry, so who do you think they take care of first?

Public land fills are burning and crushing them, which is their function in society. If public land fills are not, then the local municipalities need another bond measure at the very least. This isn't the fault of the manufactures, it's the responsibly of the local and regional governments to take care of industrial and personal waste. This is yet another example of the political and economic conditions world wide. Waste management isn't a popular topic, so it's one that gets much less attention then it deserves, but again it's not a boat manufacture issue, it's a political one.

The product producer shouldn't be liable for the end use or alternate use of it's products and it's shear lunacy to suggest such. That's the same as insisting an office building have a condo conversion plan ready, forwhen it's office building days are over, all arranged by the architect before building starts!

If a small ship yard has hundreds of tons of waste composite in it's parking lot, I'd say they're like everyone else in the industry, starving for work, cash poor and obviously not concerned about the problem as you, not to mention in an area with lax zone and ordnance laws. So, what would you have this small ship yard do Michael? Maybe they can lay off a few workers, so they can afford to have the hulks cut up and dragged off. Wouldn't that be a good idea?

Farmers with boats in their fields have either let the boat be put in their fields, after which they have no right to complain or they have recourse with the state by filing a suit against the former owner for unlawful dumping.

You really don't have a clue how the world works do you Michael? Now, go and pull up your pajamas and give mommy a good night kiss.

 

I cancelled my subscription to this post. It is going nowhere.

Love the athmosphere, keep on ranting each other, guys.

 

Its a shame...the original poster wanted recycling input.

 

The original poster made his last post on this thread at post #5 (he has posted once since on another thread). I made my first at post #6. The discussion continues on, to offer several avenues of pursuit on the subject for another page and a half, when I made my second post at post #23. Since we've move well past the idea of recycling boats as a big problem, at least in areas where they can afford to remove and dispose of the vessels. To deny this is just to ignore reality. In areas where they can't afford it or they lack the legislation or infrastructure to enforce zoning laws, well what can you do, but hope they figure it out someday.

Again, as to the original question of recycling, you can read some papers offered on the subject, a few listed in this thread or accept that not all areas of the world can address this issue currently, for a number of reasons. The reasons they can't address, be they political, social or economic are irrelevant, the fact is that recycling is preformed by those that can afford it and in several different methods. As far as material or energy extraction, well this obviously is dependent on the method.

 

To the original poster....I keep hearing reference to a composite recycler in La Ciotat but my quick French Google search reveled little.
