The Golden Age.... for Styrofoam

Styrofoam is ten times as value if it is densified. I propose a vacuum chamber.

vtx.vt.edu: Virginia Tech researcher finds a new method for recycling polystyrene
19 AUG 2022

Quote:

In a paper recently published in the Proceedings of the National Academy of Sciences, the team presents a new method for recycling — or perhaps more accurately, “upcycling” — polystyrene. By exposing the material to ultraviolet light and adding a chemical catalyst, this method creates a product called diphenylmethane (DPM) that is immensely useful. DPM is used as a precursor in drug development, polymer manufacturing, and even as a fragrance in consumer products. Importantly, DPM has a market price that is 10 times higher than other materials that can currently be made from recycled polystyrene.

The researchers took their investigation one step further: They wanted to confirm that this new method would achieve the economic viability they were striving for. The chemists from Virginia Tech teamed up with business experts from Santa Clara University and the Dongbei University of Finance and Economics, who ran an analysis to determine how profitable the recycling method would be overall. Their results showed that because DPM has such a high economic value, the costs of collecting and processing the polystyrene would be fully justified.

Over/under on when the bottom falls out of the DPM market? :)

Did someone say Golden Age?

phys.org/news/2022-08: Graphene as 'the philosopher's stone': Turning waste into gold

Quote:

This new, seemingly magical application of graphene works quite straightforwardly: add graphene into a solution containing traces of gold and, after a few minutes, pure gold appears on graphene sheets, with no other chemicals or energy input involved. After this you can extract your pure gold by simply burning the graphene off.
...
Dr. Yang Su from Tsinghua University, who led the research efforts, said, "This apparent magic is essentially a simple electrochemical process. Unique interactions between graphene and gold ions drive the process and also yield exceptional selectivity. Only gold is extracted with no other ions or salts."

Gold is used in many industries including consumer electronics (mobile phones, laptops etc.) and, when the products are eventually discarded, little of the electronic waste is recycled. The graphene-based process with its high extraction capacity and high selectivity can reclaim close to 100% of gold from electronic waste. This offers an enticing solution for addressing the gold sustainability problem and e-waste challenges.

Imagine if you could sublimate and precipitate beta-voltaic C14 diamonds. What then?

[Thanks for the thanks. Is it Piotr-sko or Piotrs-ko?]

In Polish it would be all one word, equivalent to (Mr) Peterson because Polish has male and female status indicators. However it specs out to be Czech because of the ending "o" and I have no idea if it is separated.

You're welcome.
