@goafrit, you bring a very interesting perspective to this whole subject. Am not an expert in organic or biochemistry but I believe that it will take very many mushrooms to extract 100 grams of gold from, say, a ton of electronic waste. As such, there is the possibility that while working to save the environment by using non-toxic disposal methods they may actually end up harming the environment by using up too much of the natural resources for the process.

>> . There are very few companies that do that and they are considered NGOs and they cannot compete with regular industries. Collection of e-waste from source is almost not there.

e-Waste requires special tools and technologies that developing nations do not have. That is one of the reasons why it is not done at scale. Also, the fact that most developing nations do not consume through manufacturing some of the by-products of e-waste, the market is small for major investments.

>> It shows how important these alternative approaches to mining are.

Absolutely, it has been called the next phase of mining. China leads in it. Picking rare earth metals from scraps and take them back to products. One major challenge especially for developing world is that it requires technology to do so efficiently.

You better not make such products please. People will start cutting people's hands to get a hold of the special electronics made of diamond.

Exactly. It is like using corn to fuel car via ethanol. Farmers now pure more chemicals like herbicides and pesticides to grow more corn. You are displacing fuel but you are making mess of the farmlands. Which one is better ?- it all depends where you get your paycheck!

Agree on corn...interesting trade-off on mushrooms...the best solutionis stop consuming, or make products last longer...like they used to be...Kris

They already do, but it's a very small amount of diamond. Also it is unrecoverable in so far as to extract it is to get diamond dust which is almost worthless.

Durability is not a really good business model. You can be out of business if there are no repeat customers. Just have optimality in the game. It is a difficult decision but in fairness to capitalism, it makes sense

isn't diamond dust just a coal dust? the term diamond implies crystalline structure
