You can as well just bury the microelectronics directly
That just leaves the bulk of the metals as toxic waste in water supplies; the metal compounds from: plating and electroplating industry, batteries, pesticides, mining industry, rayon industry, metal rinse processes, tanning industry, fluidized bed bioreactors, textile industry, metal smelting, petrochemicals, paper manufacturing, and electrolysis applications, etc.

#24Hands off my marmite!
Vegemite or bust. I once uncovered a ten year old jar of Vegemite (90’s era). It was absolutely amazing. I’m not sure if it matured over time, or if they changed the recipe.

Marmite has an XO version¹, which is aged for a month instead of a couple of days. Not sure I want to try ten year old mitey, but you're here to tell the tale so it must be okay ;) ¹ https://www.marmite.co.uk/products/marmite-xo-yeast-extract-...
I'm interested in what aging means here. Presumably it is different to just 'having it in a jar in the cupboard' because then all jars are aged in the supermarket for a few weeks or more. Looks like I've got my afternoon wikipedia rabbit hole sorted.

Why on earth is there a dancing jar of marmite taking up the bottom right sixth of the screen, and how do I get rid of it? I'm interested in what aging means here.

This is the first time I've seen the use of spent brewers yeast as the biomass for bioaccumulation. However, it falls short of addressing the economic feasibility of extracting the accumulated metals, an essential aspect for practical implementation. The ability of fungi to absorb metals is well-documented, but the real-world application of fungi for purposes such as bioaccumulation and bioremediation is predominantl…
Extracting metals would be a bonus, removing them from wastewater and concentrating them in a mass that can be buried for later processing is boon enough for now. The presence of heavy metals in wastewater has been increasing with the growth of industry and human activities, e.g., plating and electroplating industry, batteries, pesticides, mining industry, rayon industry, metal rinse processes, tanning industry, flui…

#28In England and some Commonwealth countries such as Australia and NZ we actually eat the stuff, Vegemite, Marmite, etc—much to the horror of others. I hope supply damand brought about by this new innovation doesn't result in price hikes for our favourite spreads. :-)

#29Any process that I'm aware of that uses yeast for something feeds the yeast, multiplying it and making it stronger. "Waste" brewer's yeast is more accurate, right?
