Shred the spools and then buy a extruder machine and use those spools to print parts, case solved.

[@Thunderstormworld]

And yes there is people showing how to do it on KZbin how to even make a extruder machine. Best of all if you have a extruder machine you can be part of the solution of plastic recycling as plastic can be recycled and won't it be good if us the 3d printing community can help reduce plastic being dumped on landfills

It's really great to see that you are thinking of this stuff. Only downside is that if for some reason Protopasta gets issues producing/delivering filament, you will have a huge issue for your company. Tying yourself to only one supplier is a risk. I'm sure you've calculated this risk and decided it is worth it, but make sure you have some kind of backup atleast!

They are complicated to package and ship, and represent a major hassle for the manufacturing. I tested these as well from a few different companies and also had many winding issues. This could work on a hobbyist level, but at our scale the issues can compound pretty hard.

[@outofdarts]

Also, masterspools still require throw away plastic zip ties that aren't recyclable. Can't say whether that's better than cardboard, but I'd guess cardboard comes out ahead.

[@theorangebaron1595]

@@outofdarts I agree with your points, some of the newer master spools have velcro straps, which are plastic, but they can be used for lipo straps and more. The master spool should definitely be pushed more than standard plastic that is spooled as Masterspools are cheaper, no spool is needed and they take up less shipping space. They are still vacuum sealed and the machine winds the plastic normally just not onto a spool.

[@DevilZcall]

My go-to supplier adopted master spool refills right from the start and I've never had issues with their winding. I'm pretty sure it would be trivial to replace the zipties with paper strips, but I understand the bigger concerns with logistics for printfarms. It's amazing to see someone from our small community drive a change that will undoubtedly range much wider.

Unfortunatelly, most of the waste separation on consumer side is just a ploy to make people feel like they're doing their part and to "shut them up". Most countries don't have the infrastructure to recycle most waste materials at all, even though they appear to separate and collect them for that purpose.

Having worked in plastics myself, and having made literally 100% of our injected molded parts out of recycled PS (polystyrene), it feels almost criminal for me that plastics are not recycled as they should be. With decent amount of care, it isn't even that hard: 1. take a plastic element 2. put it in a big grinder 3. put it in the injection molding machine 4. make a new part that's basically identical in every way to one made from "fresh" plastic (and you can do it many times over). The ONLY requirement (and I know this is the big one) is knowing what the original material was and NEVER mixing it with others (they usually then become unusable garbage, unfortunately). But small teams of people who know what they are doing can sort out plastics even without them being marked (most of the time). With so much emphasis on ecology these days, how on earth is this not on everyone's agenda? Where I live, I'd gladly come and pick up your "wasted spools" and even paid you for them by kilogram (it is after all plastic I will then use in my own production, or grind and resell with profit). Local plastic recyclers should be available by a dozen in every city. How is this not a thing?

Should be do-able with PLA, Polypropylene, Polyethylene, Nylon, PTFE, or ABS waste from a variety of streams with the proper temperature regulation and motion controls. Slogan? When in doubt, SCRU it!

Many of the plastics you named do not keep their properties and qualities as you keep remelting them, as far as I know. The resulting filament would be most likely very, very low quality.

[@SittingDuc]

Most of the filament shredder/recycler systems I have seen blend in new ("virgin") feedstock, which helps with the loss of quality issues (so only 20-30% reused material per output spool). But most systems also appear to not well tolerate a mix of polymers, so you need to know what is going in; and not all companies are forthcoming about what is "in" their "PLA+". But it is a good start! :)

The company my former job worked with had the worst system for the filament spools. They were massive chunks of plastic, and the spool rotated on an encoder, so the printer knew approximately how much filament was left. The problem was that the encoder was attached to the spool, so you were throwing out not just plastic, but circuitry too. It was only last summer that I did some digging and found out you can ship the spools back to the company, for no benefit outside of environmental impact. I mean, the least they could do would be a discount per spool returned or something!

While I love Proto-Pasta, I just wish their prices were a little less expensive. $30 for a .5KG spool is brutal.

Spool3d in Canada makes "respool" filament, which is basically just the filament without the spool. You make your own spool that you screw together. Orders over $140CAD get free shipping within Canada.

[@outofdarts]

That sounds great for Canadian hobbyists! So called masterspooling is a great option for some, but at our scale leads to many problems; larger spools introduce similar errors in our experience. We've found Proto-Pasta to be the best solution for us because they're just so local, but we encourage others to find suppliers local to them with cardboard spools or masterspooling services that fit their needs.

[@Nobody-Nowhere]

Plastic as a material is the problem, and everyone 3d printing knows its part of the problem. No matter what the spools are made out of. We are addicted to plastic, its cheap and easy. The spools just remind us of the problem, and solving the spool issue gives us a false sense of "we are doing something about the problem", while extruding plastic.

[@wubbsy]

I pretty much exclusivly print with filament from a local filament manufacturer. They are like 2km from me and you can buy the filaments without any spools and you can put them on your own master spools. And they great quality.

[@egmarauder9529]

Cardboard spools are a great idea!

[@PedroEmanuelMartins]

Where I live RepRap Portugal accepts spools to be filled with filament. But many people have sent spools of all types and brands now they can only accept the spools with the filament they make. Now they also discount 1 eur as an incentive to take back, for each 1kg spool they return. It was good to see more companies following this idea.

[@eric5866]

I have some questions. 1.John Oliver isn't known for his honesty. He's known for making incredulous statements to get laughs or claps. Sometimes true, many times not. Can his statements be verified? 2. You say 9% of all plastics have been recycled. Does that include all the plastic thrown out before people started really making recycling a thing? Does that number not include the amount of plastic privately recycled through reuse and upcycling? It's really easy to throw out vague figures to make something seem really bad or really good without actually giving people the whole picture, in fact, that's the majority of all information right now, specifically cherrypicked to fit someone's bias. These questions I'd love answered the most, because it's so easy to lie with numbers and sound honest. 3. I'm a bit older than you. I remember many phases of "being responsible." All bags used to be paper. Then we had plastic bags come in and people would literally ask "paper or plastic" and plastic was the "good for the environment" choice because paper means less trees and less trees is obviously bad for the environment. Then paper bags were nearly fully removed and we switched to plastic totally. But that does lead to a lot of plastic waste, so we moved to reusable bags. But because of the covid overreaction reusable bags have been lessened and now we're going back to paper... which is what we stopped doing to protect the world's forests from deforestation. How much of the cardboard spools are made from recycled paper. Do they contribute to deforestation? This doesn't mean I don't support your main message. I too know the horror of empty spools, although I've seen many makers use spools as a base for organization, which is cool, with printable drawers that fit into spools. Reusing these rolls, its impossible to find a use for every one, but we need more trees than we do less plastic imo. But hey, maybe I'm wrong about the source of the cardboard, in which case, more power to it.

[@outofdarts]

Thanks for your well thought-out comment! 1. We only pointed to John Oliver as a litmus test for how mainstream the concern for single-use plastics has become. We have many other sources listed in the video description which support a similar argument. 2. Also listed in the video description are articles that outline what that (generous) 9% estimate really means. 3. Proto-Pasta does use recycled cardboard (I can't remember what percent, I do apologize) for their spools; while the paper industry is not perfect, there are more sustainable practices out there now (like Oregon's reforestation efforts in the Forest Practices Act) that make deforestation less of a problem than the ecological impact of plastics and international freight. We too have seen great strides in reusing and repurposing spools on a hobbyist level, and we encourage people to continue finding new ways of limiting waste. However, our scale of printing left us with more single-use plastic spools than we could reasonably repurpose. Masterspooling, while great in theory, poses a significant hassle to both our print farm techs and the manufacturers, and it produces *different* waste and not necessarily less. I hope this addresses at least some your questions. We've found Proto-Pasta to be a solution for ourselves, and we hope others might also look into supporting local suppliers that package filament more responsibly than the standard single-use plastic spools. - Perry

The ONLY video you ever need to watch is *Wendover Productions - How China Broke the World's Recycling* For the most part, recycling plastic is based on a lie, the lie that it can be recycled in the first place. In the UK black plastic trays used in ready meals (it makes the food look 'better') aren't recyclable because the scanners in the recycling centres can't sort the colour black! As for reusing plastic for its original use, this isn't allowed for any food related items due to contamination. Everyday, domestic single-use items are really the only plastics that you can do anything about by separating them out, but it's a pretty futile endeavour given the scale of plastic usage - I think that we're encouraged to do this as it makes us 'feel better' by doing our bit to solve the problem. Another one is *The Ocean Cleanup - How 1% of the World's Rivers Emit 80% of the Pollution to Our Oceans*.

There is also the major problem recycling has, which is power. Metal is a lot easier to recycle since while it does use lose some use, you can melt it and even the common man can do it with an easy set up. Glass is also another one that the common individual can and there is also the reuse of many products. Plastic is the odd one out, since it takes a significant more planning to do anything with.

[@LoremIpsum1970]

@@josephking6251 I don't think enough is widely known on just how many types there are and the sheer scale of use of plastics, it's essentially what the modern world is made of. You only have to look at the world and products before Bakelite and realise to return to natural products is a no-go. The easiest to reuse thermoplastic, HDPE, can be reused many times but only 20% of recycled HDPE is mixed in the batch due to degradation with reheating etc. Thermoset plastics being more of a problem in recycling like nylon. Then there's the wind turbine blade problem... Who set this 12 years till we all die deadline for fossil fuels?

[@josephking6251]

@@LoremIpsum1970 I completely agree with you on that one. Two of my biggest concerns is trash patches and the issues that mining the metals needed for green energy has with soil. It's part of why I like metal and glass. The reuse capabilities are endless. With plastic, there are only so many uses before you have to say what now. If I remember correctly, polypropylene, what a lot of grocery are made out of, is the one mostly reused at that is for rope because it floats. If we could find a more industrial use for recycling other plastics such as the ones spools are made out of, like we can with both polypropylene and nylon, then we can see better uses in recycling.

[@LoremIpsum1970]

@@josephking6251 Yes, like the Wendover vid, said if there's no financial incentive there's no recycling... The irony of all the mining required for green energy and the environmental damage it will cause before the recycling systems can become self-sustaining (if that happens at all) is not lost on me. Glass is great but if it were cheaper to use we would be using more and we would have to look at the impact, esp of power needed to reuse it and on scaling its usage for nearly 8 billion users. Simple solutions are great but they must be scalable over a realistic timescale. The only financial incentives for plastic recycling at the moment is the global shipping of waste plastics - for it only to be dumped in rivers or burnt - is the biggest problem not being addressed. Here in the UK we haven't increased the recycling of plastics at all because we have no capacity to do more so it's landfill or burnt.

Geeze I wish I had known this was nothing more than an advertisement for proto-pasta when I clicked. If you want to do something about the problem, why not come up with a way of recycling the spools yourself, it's little more than shredding the plastic, melting it and extruding it to 1.75mm diameter filament. Better yet, convert the spools into energy through pyrolysis. Work to fix the problem rather than just ignore it.

[@outofdarts]

Not an ad, just the facts. Proto-Pasta is local to us, and cardboard spools are the way to go to reduce landfill waste, even with the existence of masterspooling. We are not equipped to become a spool recycling facility, and such equipment is more expensive than the small amount of money we would save not using Proto-Pasta. Proto-Pasta just makes sense for us. If you have a local supplier that takes spools back or recycles them into filament, then go for it. If they use cardboard spools, vote with your dollars and the industry will follow.

@@Alegzander1990 Thanks for your criticism. We are actually thinking of following this video up soon , because comments like yours have highlighted some gaps in our persuasive argument. For us and those local to Proto-Pasta, the answer is obvious because their spools are reusable, recyclable and sustainable. It makes it a really easy decision when you not only cut out single-use plastic spools, but also additional packaging and freight. For other people outside the Pacific Northwest (and this is where our point was lost), we encourage people to find local suppliers that use cardboard spools or that use masterspooling -- even if it's more expensive -- rather than rely on filaments where the spool and other packaging would end up in the landfill.

[@Alegzander1990]

@@outofdarts Fair enough i suppose. It was the first video i've seen on your channel so i am not familiar with your channel or your business. I must say though that i am pleasantly surprised by your response. However there is still one thing that does not compute, and that would be : *"we encourage people to find local suppliers that use cardboard spools or that use masterspooling -- even if it's more expensive -- rather than rely on filaments where the spool and other packaging would end up in the landfill."* The answer to that ( and i would like to emphasize *"even if it's more expensive"* ) is simply ... NOPE ! Why should the end user be paying for the state (or whoever else's) inability, actually let's be frank, unwillingness to recycle as they should ? If by *"we encourage people"* you mean the average person 3d printing as a hobby and maybe also printing some functional things for himeself and those close to him, then this doesn't make any financial sense to be honest. This form of manufacturing BARERLY became affordable to the average person as of fairly recently and now "the plan" is to make it unafordable again because plastic is not being recycled as it should ?? If you also include businesses in that group, then good luck with that, especially in TODAY's capitalist environment. Sure, you guys did that, but then again you've got a say in the production process, you have custom colors, you sell those filaments (or at least you get a cut, if i understood correctly) so it's not like you have nothing to gain here and merely did it for "the planet". That is why i said previously it comes off a bit as "patting yourself on the back". As if ... Anyway, my point is this : Coming up with a video and telling people that they should spend X.XX amount of times more on filament to "save the planet" should not be taken lightly, ESPECIALLY when you've got a horse in the race... That's my stance. I have nothing against you guys (like i said, i don't even know you) and nothing against Proto Pasta. If we really want to solve the problem, then i think the root issue is plastic not being recycled as it should and THAT ought to be addressed. How that could be done, i don't exactly know, i suppose it depends on where you are. Lobbying for it in the US, speaking to your state representatives, i don't know, but the root cause needs to be addressed. Plastic doesn't end up in a landfill just because of 3D printing and i feel it's unfair for your average hobbyist to bare the potential increase in cost. If they can find a supplier that provides cardboard spools at the same price or a price they feel comfortable with spending, then sure they should go for it and may also feel good about themselves for that, but the ROOT ISSUE will still most likely exist, therefore that's just a drop in the ocean. Sure, it's a start but the pat on the back is STILL unwaranted. In conclusion : I'd rather buy plastic spools and lobby or speak to my state representatives about the problem of plastic recycling rather than paying more and not actually achieving anything in the grand scheme of things except for a fake sense of "self satisfaction".

I commend you for your choice of using an environmentally conscious supplier and working with them to reduce, reuse, and recycle the spools. Personally, I think all manufacturers that use plastic should be responsible for recycling that packaging from the end user. I realize that may be expensive, but it would drive manufacturers to find a better, more sustainable solution. We should all use the power of purchase to drive more sustainable solutions to the plastic recycling problem by not buying products that are not recyclable, like using reusable water mugs instead of plastic water bottles and such. I will start to use Proto-Pasta filament for my 3d printing for this reason. Thanks for making this video!
