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.'"

      Very little of recycling is anything but very wasteful. Penn and Teller did an episode of their show "Bullshit!" about it and it was quite illuminating. In terms of energy costs and such, the only time recycling ever turns a benefit is in the case of aluminum cans. Everything else is a huge waste. Especially paper, since all of our paper comes from tree farms specifically grown to supply paper. You're not killing acres of forest when you throw out paper, you're probably planting a new tree.

      And don't get me started on the fact that plastics only last 1000 years in a dump if you bury it like an idiot. Plastics are photosensitive and will decay rapidly if just left where they can get sunlight.

        The problem is that you are thinking in terms of energy and not raw materials. Depending on where the energy is coming from, using more in recycling vs. production may not be a problem. If the raw materials are in limited supply or dumping space is limited, the recycling still makes sense if you can recycle significant quantities. Although I didn't watch the Bullshit episode.They may have covered more than just the energy aspect.

        The paper issue is interesting though because you might consider discarded paper as a carbon sink.

        As for not burying plastic... What do you suggest we do with it? Fill desert areas with trash? What kind of chemicals does decaying plastic leave behind?

        • I think you've nailed the idea. It's not just energy ROI. You have to consider the costs of disposing of the trash as well, as people don't want loads of trash sitting around and certainly not getting imported from places where there's no room. It's why recycling doesn't make as much sense in the midwest as on the coasts -- it's reflected in the tipping fees you pay for trash. Here in MA we pay about $85-120/ton to dump trash, plus hauling fees. In the midwest and southwest it's down around $30. So re

            • Yes, but 1) you're using it already, so it can't be used for anything else, 2) hydropower is going to be an increasingly small percentage of the earth's energy supply due to it's own environmental problems, and 3) it takes a long time to ramp up new power capacity. On the order of 10 years per plant. Whatever replaces hydrocarbon fuels is definately going to take a longer timescale than the average slashdotter has left to become the majority energy source.
          • Energy isn't the only cost driver. Employees and tipping fees are also big pieces of the pie. When they're high enough, recycling makes sense. Energy isn't everything.

        tree farms
        With a few exceptions there are no such things as "tree farms". There are forests. Some of them are managed and some of them are not.

        The problem with your logic is that the tree you just "planted" by throwing out paper (wtf?), is not going to provide: shade or habitat or prevent erosion or breathe in a comparable amount of carbon dioxide. There are lots of other externalities you've neglected to account for, such as the chemical treatment it takes to produce paper pulp from wood (more so than recycled pulp). Nobody counts that because it gets dumped into the air, oceans and rivers.

        According to some reports, many of North America's largest catalogs and tissue product manufacturers use virgin boreal pulp [nrdc.org].

        Often in managed forests, where, as you triumphantly declare: trees are "specifically grown to supply paper", the trees that have been planted are not indigenous to the region. This endangers native plant and animal species, such as in Chile [panda.org].

Other recyclable materials, such as metals, are easier to process mechanically.

          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

      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.

    This silly idea for recycled sidewalks is totally stupid, it completely ignores the basic facts: you're not taking garbage out of the environment, you're just distributing it in different spots, like EVERYWHERE. So instead of old rubber rotting away in a massive pile in a dump, it's rotting away in everyone's front yard. I think this is infinitely LESS preferable to concrete, at least you can rip up old concrete, break it down into gravel, and use it to make NEW concrete, and even in a dump, concrete is totally inert. But a recycled rubber sidewalk is just going to decompose and end up as hydrocarbon pollution that enters the ground and groundwater. If you dispose of tires in a dump, maybe you can put it in a clay-lined dig, where the decomposition products won't run into the ground water, but if it's in everyone's front yard, it won't take long before the pollution ends up in the land, water, and in our bodies.

    Back in the '80s a business partner and I had a company that literally turned garbage into gold. We would deinstall old mini-computer installations. Minicomputers for those too young to remember were often larger than refrigerators and could have hundreds of circuit boards in them. We'd then pull the board from them and since the computers still had an installed base but few parts available sell the parts to 3rd party repair depots around the country. Whatever didn't sell got boxed up and sent by the ton to a smelter who would extract the gold, silver, copper, etc. Some circuit boards, NCR for instance, had every trace and ground plane gold plated many times thicker than the connectors on today's computers.
