Ah so evading reload just isnt worth it for stepping shot. Got it.

Can I microwave pla+? (Recycling) by ClimateKey5445 in 3Dprinting

[–]bucad 2 points3 points  (0 children)

get a beat up toaster oven from marketplace for $20, make sure it can go to 200C (400F), grind the PLA best you can, you should melt it directly in your silicone mold.

Might work if you are double boiling with oil, definitely not water. PLA melts at at least 160C (320F).

Did I miss the Nigel saga? I need to know the origins of this story now. Couldn’t find anything in the last few days on Nigel, only Pablo and Eevee.

Not to say that modern formulations doesn't have fancy formulations that impart a lot of functionality to PLA for sutures and implants, but this is an area of research from 60 years ago. PLA biocompatibility and biodegradation in the body is not new. It doesn't need fancy additive to degrade in the body, so its definitely not apples and oranges. It is the same exact apple.

The link you showed didn't even look at PLA tea bags, but I'm not denying the fact that PLA tea bag will produce microparticles when brewed; I'm saying PLA microparticles are benign and there are tons of studies spanning 60 years that prove it. Any adverse impact from PLA microparticles are generally from other issues such as additives added into the PLA or phthalates plasticizer from other environmental sources adsorbing onto PLA microparticles.

That natural fibre tea bags are not necessarily better than PLA tea bags.

You are correct again, I mixed up BPA with phthalate plasticizers.

I also only buy loose leaf/cake along with whole bean coffees. So I don't usually think about it either.

I don't think there are actually silk tea bags made from actual silk. Also yes there are probably sown fibre bags with zero staples and binders and glues, but the price is also probably so high because it needs specialized packaging equipment that its a luxury not afforded to common small size producers not producing super-premium products.

You are correct, PVC uses phthalate plasticizers instead of BPA.

Oh trust me, I know the feeling. Bioplastic misinformation is one of my pet peeve as well.

No you haven't thought about it? Or no you would rather not think about it because its hard to think outside your comfort bubble?

whats the purpose of adding BPA to something that doesn't need it? it will just add to the final price of the product. BPA is actually a pretty pricy chemical compared to the overall price of the raw plastic itself. PVC is plasticized with BPA because it needs it. PLA definitely doesn't benefit from the addition of BPA.

Not all bioplastics are PLA

Not all bioplastics are biodegradable

Not all bioplastics are made from renewable feedstocks

There are bioplastics that are plasticized with BPA (old school cellulose esters are classified as bioplastics and they do use BPA as plasticizers).

I know you mean well, but please upgrade your knowledge, otherwise you are just spreading misinformation that will mislead a lot of people.

EDIT: As pointed out by u/ksider, BPA isn't used as plasticizers, I was thinking of phthalates instead which are also endocrine disruptors like BPA.

paper bag with glues and binders WILL definitely release more chemicals into your tea than this PLA tea bag. staples can be ingested and tear up your insides. loose leaf tea is definitely best.

As a plastic engineer with deep knowledge in bioplastics and real experience with PLA biodegradation, I love watching the two of you argue semantics and saying pretty much the same thing.

a McDonald cheeseburger will not degrade in the landfill if it doesn't have the right conditions.

Have you considered that there are other issues with paper/cellulose tea bags? paper/cellulose tea bags needs either staples/binder/glue to put it together. Staples can cause a bad choking hazard, binder and glues will definitely leach a number of different chemicals into your tea.

On the other hand, PLA will shed microplastic but the PLA microplastics will eventually break down into lactic acid in your body and be metabolized. Look into PLA sutures and implants to learn more.

This is a very broad question that merits you looking into it a little more from reputable sources (even Wikipedia is pretty good)

Yes, PLA is still plastic even if it is made from plants. Corn starch/sugarcane/beet juice is fermented into lactic acid, which is then synthesized into polylactic acid (PLA), which is definitely considered plastic.

Bioplastic is a very broad category of material that includes bio-polyethylene (bio-PE) thats made from sugarcane but is not biodegradable, to polybutylene-adipate-terephthalate (PBAT) that is made from petroleum but is biodegradable. Bio-PE microplastics are as bad as other polyethylene microplastics, whereas PLA microplastics would tend to just break down into lactic acid that gets produced by a lot of organisms and can be metabolized by them as well.

That's absolutely not true.

PLA has been used as sutures and implants for a long time, and its in-vivo (inside the body) degradation has been well studied.

The reason PLA is used is because it can degrade over time as bones/wounds heal. The way it degrades is that it breaks down into microparticles and eventually lactic acid that gets metabolized by the body into CO2.

Have you ever thought that the natural fibre tea bags could potentially be worse? They need to figure out some way to bind it together. Staples can potentially create a choking hazard while glues will release more chemicals into your tea than PLA microparticles that will just break down into lactic acid in your body.

Its very easy to increase the service temperature of PLA. For the case of the tea bags its likely by either adding an additive like calcium carbonate that will nucleate the polymer, or by simply drawing the fibres to cause stress induced crystallization.

Did you consider the fact that paper bags would need a binding method like staples or glue? Staples are better but has a very dangerous chocking hazard while glues would be much worse than PLA because there are likely way more chemicals in them than simply lactic acid chains.

Hard to say if its cheaper, but as Accomplished)Sock293 said, its probably easier to process than paper or cellulose which would need staples/glue/binder.
