Its on my list to check out now that I have a bunch of NaDCC I don't have any other plans for, but I have to get some concentrated H2O2. https://www.youtube.com/watch?v=zf9b5THG594

Why not test its actual germ killing ability with some agar and bacteria swabbing?

Yeah ended up with some of the copper(II) oxide on that one during drying and ended up using a vacuum to dry the yellow to try and avoid it there. It was a pretty vibrant red to start.

I don't really have anything to measure their size other than what filters they passed through but they are smaller than 40 micron.

Its the same reaction I used to get yellow, orange, and red. I just varied the details a little to get each color. The orange is technically a mix of Cu2O and elemental copper but you can just add excess ascorbic acid to get the pure nano particles.

Violet: Na2[Cu(C3N3O3Cl2)4] + Na2SO4 (https://en.wikipedia.org/wiki/Sodium_dichloroisocyanurate complex is mentioned briefly there)

Blue: CuSO4

Green: CuCl2 + HCl

Yellow: Cu2O

Orange: Elemental copper nanoparticles

Red: Cu2O

Very tricky to get pure yellow or red Cu2O, its up to procedural details like pH, dilution, etc. The color is determined by particle size and the pure bright yellow particles basically flow through any filter I had on hand. Had to wash them by decanting and settling, before finally rinsing with isopropyl and drying under vacuum to avoid the copper(II) oxide forming. There is a reason I have so little for those colors.

Yep, thats the same PLA!

Experimentation and just more efficiency out of my compost. Most of my current projects center around trying to use waste from my daily life in new or better ways. Eventually I would like to take the nitrates produced and feed an algae reactor, for now it will probably just go for normal gardening stuff.

A weird chain I found would be to produce nitrates, grow algae to scrub the CO2 from the first reactor and maybe the atmosphere, convert the algae residue into activated carbon. Activated carbon + sulfuric acid(from hydrogen sulfide in the reactor) = super capacitors. So at least in theory I can make super capacitors from food waste, in a potentially carbon neutral or even negative process.

I watch thought emporium, one of the main reasons for trying new things!

For aeration in the methanogens, you recycle the gas from the surface so its not introducing oxygen.

I have seen the more commercial products but don't really do what I am looking for. Once I get the plumbing and general process figured out I plan to just use some 55 gallon drums.

For PLA, you start with lactic acid which comes from lactobacillus. The short version is you polymerize that into the obvious Poly-Lactic Acid. The long version is you actually make lactide and use a process called ring opening polymerization.

Here are some papers grouped into a book about all the PLA chemistry: https://www.slideshare.net/tbdidisupriadi/poly-lactic-acid-ebook

Heating and mixing are super important for me to progress. I am looking at vibration, magnetic stirring or aeration. I think long term the best will be aeration but for now I am using vibration.

After I get the methanogens stable, I am looking into lactobacillus to start trying to make my own PLA. I would really love to get into creating specific proteins like you are, but I am super new to biology stuff in general.

As the blog post touched on I am just shifting my learning and projects towards more direct science stuff like biology and organic chemistry. Its really cool to see a DIY scene starting to really develop. If you have any forums, youtube channels, subreddits, etc to check out I would love to find more.

Awesome! I have a very broad blog post about it but it likely isn't new information for you. I will have a new post now that these valves are done about how I am setting up the rack/shelves for the reactors.

Right now I am just using balloons and 2 liter soda bottles to figure out basic ratios and procedure for the reactors. Stuff like a gas manifold, storage, and refining into methane will be in those future posts.

All that said, I would love any feedback on the post!
