So, how does polyester fabric recycling work? Unfortunately, for the time being, it is by far and large not practiced.
- Polyester production:
- 60% clothing
- 30% bottles
Therefore, most recycling must happen from the clothing. Unfortunately, this is where collection infrastructure simply isn’t in place. And when it is, the recycled fibers often times aren’t of high enough quality to be sold for general clothing, only “forgiving” uses like winter wear. That is, using the mainstay common mechanical reycling method. Chemical recycling is exceedingly rare.
Finally, the problem with non-biodegradable materials. Human society will always drop materials and let them run loose from the human world. Once they go drifting out in the natural world and never biodegrade, that’s where they can cause harm. Or maybe they do biodegrade and leak out poisonous substances into the environment, which ends up in water supplies and right back to humans.
Also unfortunately, recycled material demand outstrips supply, mainly due to lack of consumer focus on recycling, so some unscrupulous suppliers will manufacture new bottles and ship them to the recycling facility. Yes, so as unfortunate as it is, even though we have the material resources to supply manufacturers with a greater quantity of recycle feedstock, it’s not happening. Perhaps the problem is greater for plastic than it is for paper.

Footnote: Unfortunately, this is the problem with recycling anything. Collecting, getting the items to work with. When those who have do not want to distribute them to the right places that can make the most use out of them. It applies with information and data collection too: when one no longer care about information and wants to “throw it out”, will they permit reuse of the information for other purposes? Obviously, in the case of information, this is more of an intellectual phenomenon than a physical one, since it is quite likely that humans are totally incapable of destroying information: the fabric of the Universe always remembers.

The reality that people have to accept. You cannot destroy information but you can make it more difficult to access. So, what is your quantitative threshold of difficulty of access? Yes, in statistical terms. Given that there is for certain one “exploit” that will happen in the distant future, thousands of years later, how many exploits on average are you okay with over what period of time? Also, compared to the actual statistics of exploits from other methods.
Also, let’s be concise about the defining criteria. If the actions have no effect on you, absolutely zero, then there is no reason to be upset. Why? Because the actions are imperceptible!

Now, carpet is a great source for recycled material, unfortunately most of it gets thrown away rather than recycled proper, often times due to lack of infrastructure.

So, all that being said. For local recycling. Does the Prusa i3 support a filament width sensor? Indeed, it does, and there are some people using it.
