Producing graphene in bulk using waste food, plastic and other materials (opens in new tab)

Usually though, what we have in the US is that foodwaste goes to landfills (bad), and then lawns are grown with fertilizers (instead of compost). That's a much larger carbon cycle that ends up depleting the land in multiple ways. Let's not even get to how wasteful we get with water management -- pumping water, purifying them to drinking water standards, and then watering lawns with them.

How strictly is that enforced? And is it applied without exceptions? For example I compost but if I have something oily I'm going to compost it because oily soil isn't great.

Carbon that is eaten and used by plants, sequestered in soil are bio-available in the ecosystem, and if designed well, then there can be many kinds of yields useful for human. Healthy soil -- not dirt! -- with living organisms holding it, has a dramatic effect on the microclimate of the area, and helps regulate the microclimate across the solar cycle.

When you have bare dirt, and no plants or anything living there, then the area gains more temperature variability.

Because of the way we farm in the modern world, we leave a lot of bare dirt around. Thermal satallites show a rise in temperature every year during the planting and harvesting seasons. The idea of reducing carbon emissions from industrial processes and cars will not reduce the climate extremes we are seeing. Having better land management, tightening up carbon and water cycles in microclimates helps a lot more, and have many beneficial side-effects (such as reducing weath inequality gaps, having stronger more cohesive communities)

But an example of what I am talking about. The film is focused more on better water management, but it's integrated with bringing fertility back to a wasteland. The water harvesting strutures discussed in the video are dug in a way that also accumulates organic matter so that topsoil can rebuild on what is otherwise bedrock. https://youtu.be/KtHuIlfyJao

In theory it’s a great way to reduce this non ecological material into fuel, in return into something that is ecologically compatible.

plastic is just fuckd

There's a carbon cycle of plants -> oil -> plastics -> burn in air -> plants -> oil ... And that cycle takes a long time.

But the carbon cycle I am thinking of is one that makes the carbon in the plastics bio-available to plants directly. That means greater fertility, greater food abundance, food sovereignty, better land management.

Trying to stuff the carbon from plastics back into rock does not give us greater fertility, food abundance or food sovereignty. If anything, it will increase the wealth inequality gap, and makes it harder to feed everyone.

We're not quite there yet. The key is being able to safely composting plastics, and that means finding or breeding microorganisms that are capable of eating it. What we would have to give up are the properties of plastic that our modern society is addicted to ... something that _doesn't_ biodegrade, durable and cheap enough to be used ubiquitously.

do you know any good places to read, or sites to follow about graphene research ?

I was interested in the flash joule thing to play with conductive ink or insulations..

First, it probably isn't monolayer, but rather variable layer numbers, so practically speaking... it's probably graphite.

Second, there is likely to be a lot of defects. So you don't get the full strength that you would find with single crystal exfoliated or epitaxially grown graphene.

Still, I would imagine that a method like this could be useful, particularly if you were building a colony off-world. You don't need high-quality graphene for making composites for construction.

He didn't explain in details saying telling more would be intellectual property breach and that a lot of companies are searching for flash joule like techniques and if they were working they'd be in use yesterday.
