I think I'm going to start wheatpasting propaganda to the concrete wall protecting my own dumpster, on the back side facing my compost heap.

No one but the folk who hang out back here will see it, but also, no one but me would take it down, so it can stay up for a long time.

So, @ me with some good black and white shit I can print on some basic whatever-size-paper-Americans-use

@emsenn I'm assuming wheatpaste is an organic glue made from flour, but this is my first time encountering that particular phrase.

Just flour and water?

@ajroach42

2 parts high-gluten flour to 3 parts water bring to a boil add another part water simmer for an hour.

Makes a fairly thick paste that's great for adhering posters for a looong time.

@emsenn

This has my wheels turning.

I used to make a clay out of a similar mixture with the addition of corn starch and salt when I was a kid.

I imagine it dries white, and isn't anything close to water proof but is otherwise pretty strong?

I'm looking for a mixture I can add to paper to stiffen it enough that it can stand up to children playing with it.

Right now, my best options are soy wax for some situations and PVA glue for others but I'm looking to find an alternative to PVA.

@emsenn Also, without rehashing all of our plastics talk, I would appreciate your opinion on PLA (if you have one.)

Right now, I only use PLA in one offs, but I came across some new techniques that have me reconsidering its applications.

It's made from renewable biomass (corn, sugar, or beet pulp usually) and can be composted. Alternately, it can be cleaned, shredded, and re-extruded in to usable plastic. (1/2)

@emsenn While it is PLA's mechanical properties that have me considering using it, a recyclable, compostable, bioplastic sounds to me like it would be less harmful than other available plastics.

I'm certain, though, that the data I have on the plastic is skewed by my general desire to work with plastics, and the plastic industry's desire to not stop existing. If you have a less biased view (or just a view with different biases) I would welcome that as part of my decision making process. (2/2)

@ajroach42 Most of what you've said is good is true, as far as I know. There's really two issues I know of:

- systemic: we grow corn for PLA and fuel when we're still struggling to feed people. Could we do both? Certainly. Do we? No. I'm concerned sourcing PLA encourages continuing that.

- practical: Wear and tear on PLA parts means tiny fragments of plastic ending up in your dust, dirt, everywhere. This is where a mega-innovation like new bacteria could be really useful 1/n

@ajroach42 much the way we've learned "hey throw this dried up fungus on your garden and it'll make your plants roots better," we can learn "hey throw this mix of bacteria in your compost to eliminate the microplastics."

But we don't have that yet, which has me so cautious about ALL plastic use. Which is a big bummer because except for that, gosh, it'd be amazing, for all the reasons you say.

@ajroach42 Now that still does leave lots of use for plastic, like in industrial facilities where things are properly captured at egresses, but for residential/small-scale use? I mean, I can see bits of plastic in the dust I sweep up around my apartment, and that's got me worried.

It still goes into the compost because what the fuck else am I to do, and I try to sift out what I can, but eesh.

@emsenn I appreciate this very measured response, and now I have even more to think about.
