No such place

The Artdog Quote of the Week


The first thing that leaped to my mind when I read this was the Great Pacific Garbage Patch (although all oceans have them, and there actually are more than one in the Pacific alone, depending on how you look at it/them).

Pacific currents and how they accumulate garbage--particularly troublesome are the plastics.

My second thought moved on to landfills and their limitations--which are many and becoming progressively more difficult to deal with. And that's not even beginning to talk about the problem of illegal dumping (also called "fly-tipping" and other, less savory things), which is a persistent problem almost everywhere.

Even the familiar process of recycling can be less "green" than we'd like for it to be, since volatile markets for recycled materials and contamination or un-recyclable items can elevate the cost of recycling for municipalities. The problem has been growing for years, and solutions seem elusive.

Sorters in recycling plants are essential, or all sorts of non-recyclables can get through to gum up the works.

As in most areas of life, public education is key, smart government policies can make a huge difference, and realities are always changing, so innovations that change with them are always needed.

We all have a part to play. How's yours going?

Speculation: A New Source of Domestic Oil Production?

Please note! This post was updated 6/3/2015.
Indulge me for a moment, while I do what science fiction writers do: put two ideas together that don't necessarily fit.

My imagination was caught today by a video a friend posted on Facebook this morning.

At first I worried it might be a hoax, but no--this technology is real.

It, or variations much like it, is being used all over the world, scaled up in some cases to an industrial level (see PK Clean, Agilyx, and Plastic2 Oil), or on an individual-household scale.

Pretty cool, huh? wouldn't it be great to see this technology spread?

Convergence Zone in the North Pacific Gyre.
However, anytime you mention plastic waste, my mind turns inevitably to the Great Pacific Garbage Patch. It is a vast floating convergence of marine trash--mostly plastics--created by current action of the North Pacific Gyre and the carelessness of people.

The Garbage Patch is located near the Midway Atoll, which is US territory, near the Hawaiian Archipelago. The Patch conservatively estimated to be the size of Texas, and it is a massive source of pollution and environmental destruction.

One of the most destructive aspects of the Great Pacific Garbage Patch is that the plastics in it break down in the sunlight and are ingested by birds, sea turtles, and other wildlife. This causes all kinds of trouble, such as when the animals can't pass the plastic, it fills their stomachs, and they starve. That's not the only bad effect, but it's a dramatic and all-too-prevalent one.

There are other Garbage Patches in the world's oceans, of course, including the Great Atlantic Garbage Patch, and the Indian Ocean Garbage Patch. These swirling wastelands of trash are a global blight.

So of course I went there. What if we could park ships equipped with plastic-to-oil plastic-recycling technology throughout the Great Pacific (or other) Garbage Patch? Our national policy the last few years has been focused on building energy independence; maybe this could eventually make the oil shale in North Dakota's Bakken Formation look paltry.

Maybe it could put the idea of drilling in the Arctic National Wildlife Refuge off the table for good?

I'd certainly be happy about less fracking, less impact on fragile ecosystems, and more garbage removal from the ocean.

I'm not the only one who's concerned about cleaning up the ocean, of course. The Ocean Cleanup team has a system that might be adaptable to my idea--it is scheduled to deploy next year. (Thanks for this info, Suraj Mohan!)

Yes, yes, I know. I'm WAY over-simplifying. My idea is impractical for thousands of immediate reasons. But what if they can be overcome? The key to any innovation is first to think of the idea, then solve the problems that currently make it impractical. Simple? Easy? No. Worth considering? We won't know till we consider the possibilities for a while.
