Turning Garbage into Gold
bart_scriv writes "Entrepreneurs are creating companies that exploit the creative opportunities in other people's junk, sparing the environment in the process. The article looks at green entrepreneurship in general and profiles some specific companies, whose products range from recycled printer cartridges to rubber sidewalks. It also includes a slideshow on the process of making rubber sidewalks. From the article: 'While innovation has always been the entrepreneur's trademark, a growing interest in the green movement is propelling small business owners to create new products and services that also happen to be inventive recycling solutions for the country's vast waste heaps. 'The sustainability and restoring of our environment are providing opportunities in many fields of small business,' says John Stayton, co-founder and director of the Green MBA program at San Francisco's New College of California.'"
I was hoping for something relatively cool in the rubber sidewalk slide show - instead, all I got is some shots of ground up rubber and a very ho-hum sidewalk paver install. *yawn*
The bags made out of old inner tubes cost way more than similar bags imported from China and sold at Walmart.
The trick to recycling is to do so in an economic manner.
This is ridiculous. All this is is people finding a way to make money. Nothing new. It just so happens that they're using waste from other businesses. It has been happening in one form or another for as long as any semblance of free markets have existed. There's a niche, and people are filling it. These aren't people out to save the world. These are people out to save a buck, and the way that they do it happens to recycle scrap. Big fucking deal.
2-10 lbs of lead?
I find that very difficult do believe. I mean that's 5-25 POUNDS of solder. What the hell are they doing in there?
The heaviest thing in a television set is the picture tube. Since it's big and filled with vacuum it must have very thick walls. Thick glass walls. I suppose they could be lead crystal glass tubes, but that would be needlessly expensive, and wouldn't leach into the water supply in any meaningful timescale anyway. The next heaviest thing is the hundreds of wrappings of thin copper wire. There is no reason to ever make thin copper wire out of lead. In fact, it's impossible.
That figure smacks of taking advantage of people's ignorance about a heavy rarely opened box in almost everyone's homes. There's gotta be some kind of term for abusing people's uncertainty about things to encourage fear to promote some kind of crazy agenda.
Can you be Even More Awesome?!
"the chemical treatment it takes to produce paper pulp from wood "
and what about the chemical treatment to recycle paper?
The Kruger Dunning explains most post on
That's really just two ways of saying the same thing. And in any case, isn't delaying the inevitable a worthwhile thing to do? The more slowly the landfills fill, the more time we have to come up with a way to solve the problem.
When that happens, we will have the same volume of trash as we started with.
No matter what happens (barring space exploration, and meteorites, anyway), we will always have the same volume of stuff that we started with: one Earth-sized planet's worth of various materials, mixed into various combinations that are either more useful to us, or less useful to us. The trick is to increase our skill at converting the less-useful forms (aka "garbage") into more-useful forms (aka "products"). This is a step along that path.
I don't care if it's 90,000 hectares. That lake was not my doing.
Every trip through the recycling cycle degrades the material to some extent...
Nonsense. Aluminum is aluminum is aluminum. Steel is steel. Silicon dioxide (glass) is silicon dioxide. You melt them down, blow off the impurities, and you are exactly back where you started -- and I mean right down to the molecule. The idea that somehow the Fe atoms that are part of your 2006 Ford car door might be "degraded" because they were once part of the trunk of a '56 Ford, and before that formed the bearing on a pushrod in a locomotive built in 1908, is inconsistent with basic principles of chemistry. (Biological recycling is even more efficient -- your food doesn't taste faintly of shit if the farmer manures the field.)
The only place you could make this kind of general argument is for composite polymer materials -- e.g. plastics, rubber and paper -- where it's not economical to reduce the materials to their original chemical form. Practically speaking, you can't reduce polystyrene waste to the olefins from which it was originally polymerized, in order to purge it of impurities, restore the original degree of polymerization, and restore the original composite mix of resin, plasticizers, et cetera. It just costs too much, as someone else has pointed out. So these materials are not, at present, significantly recycleable in any meaningful sense.
Instead, as in TFA, one "recycles" materials like these only in the toy sense of taking the used material and shaping it into another form for a while. It's as if you took your old, rusted-out car body, and, rather than melt the steel down and recast it into a pristine rust-free new car body, just turned the rustbucket into a planter, or some funky rust art. Or like my grandfather re-using wood from packing crates to stake up his tomato plants. Or GIs in the Second World War wiping their asses with pages from Stars and Stripes.
I don't think this is true recycling. It hasn't a prayer of ever becoming a closed loop, where the material recycles more or less endlessly, and you just supply energy. Turning your rusted-out automobile into a planter doesn't solve the fundamental problem at all, because the planter's just going to go into the dump itself, soon enough. You haven't done squat to figure out a way to truly close the loop, to turn the worn-out product back into a brand new product of the same type and quality.
Such "recycling" is a gimmick, an abuse of language, which conveys the false impression that something much more useful is going on than really is. The fact that some miniscule fraction of bicycle tires could be re-used by consumers one more time, for a year or so, as part of a rubber bookbag, can have no serious impact on the problem of our waste stream. It's re-arranging deck chairs on the Titanic.
Does it matter? Sure. Effort spent re-arranging deck chairs could be better spent trying to plug holes below the waterline. When people hear about all this "recycling" they may figure, hey, plenty's being done, and pay less attention to efforts at genuine recycling. (For example, although steel is infinitely recycleable, and very economically, only about 60% of American steel cans are recycled. That's idiotic.) Toy solutions can easily delay and prevent real solutions.
In any case, the more interesting thing is that entrepreneurs are beginning to see the profit potential of recycling garbage.
Good grief. Are we to suppose engineers have been idiots until early in the 21st century? Any fool understands that if you can figure out a way to turn "garbage" (what you can buy cheap) into "product" (what you can sell dear), then profit follows as night follows day. Consequently, the history of technology is chock-o'-block full of engineers taking "waste" products and finding new, useful things to do with them. This isn't a new insight or development, it's as old as compost heaps.
One historical example, relevant here, is that our entire modern plastics industry is based around the
