back to article You know all those resources we're about to run out of? No, we aren't

Among the more surprising things that the BBC revealed to us last week was that the UK was going to run out of coal within the next five years. Given that the island is pretty much built on a bed of coal, this is something of a puzzler. The northern end of the huge water-filled pit, showing the coal seams in the rock at Broken …

      There are two potential problems with recycling, that may only apply in certain cases (The upsides are obvious.)

      1) Sometimes it's much cheaper to extract more virgin material than to recycle old. Or it may be cheaper in simple monetary terms, but require lots of energy, which may cause environmental damage down the line (e.g. greenhouse gasses) meaning what you save now you pay for later.

      2) Maybe the intention isn't to actually get the public to recycle, but to set them up as the scapegoat when (possibly artificial) shortages occur. "See, we told you to recycle, but you didn't. Now we have a scarcity, so you must pay more. No, it's not us being incompetent/greedy, it's you being too lazy to recycle."

      recycling of metals

      Recycling isn't always a good thing

      it isn't just 're-using' the metal, it requires obtaining the thing that the metal is in (logistics), stripping it out of the thing, isolating the metal you want, processing it for new use (simplified).

      So, you then have 2 scenarios:

      1. Recycling/Reprocessing metal A requires less resources / pollutes less than digging up and refining from scratch.

      2. Recycling metal A requires MORE resources / pollutes MORE than digging up and refining from scratch.

      If its 1, then recycle away :D.

      If its 2, then be careful of recycling away, as you are polluting more than you have to, but at the same time you get that warm fuzzy feeling from recycling and saving the planet (so you think you are doing good, but you aren't).

      There is a question of where to put the thing with the metal in it after it is no longer required wanted (like an iphone 4s now that iphone 5 is out).. if scenario 1 and 2 are roughtly the same you may make the suggestion that scenario 1 is better as it cuts down on needed space for landfills. Or you could make the point that if we put it somewhere with others like it then we will have a known source of materials in the future...

      Philosophical question: If at some point in the future we start to mine landfills for materials, are we then recycling previously abandoned waste, or are we extracting ore from the ground, or both?

    Forecasting is so depressing

    Any worthwhile economic forecast should include a reference to the previous one. So the next time you see a price prediction for oil, gas or similar in a years time it should include a comparison of today's price and the previous forecast.

    Maybe you will be surprised by their accuracy, but I doubt it.

    Is part of the problem that only hysterical forecasts and reports get any coverage?

    In the Western world, Sales type personalities are far more compelling than Engineer types.

    All of our politicians and many of our senior managers/directors are all in the business of Selling stuff and rely on charisma and force of conviction to persuade others.

    The people who actually know stuff are usually consigned to advisory committees and the problem is that these committees are rarely listened to, particularly by politicians.

    That's why China is eventually going to stuff the lot of us.

    Incidentally, I see the point of recycling not so much that it's about saving natural resources - after all, the first things to be recycled were glass and paper, and there's practically limitless quantities of both. No I thought the point is to reduce the amount of waste going into landfills.

    1. Stuart Van Onselen

      A properly-designed landfill is perfectly safe, and it's not like we're ever going to run out of holes to dump things in. For example, every mine-pit we dig up now is a potential land-fill site later. It's like a special case of recycling, come to think of it. ;-)

        Not quite so fast

        You cannot put a landfill just anywhere. You currently need a deep clay layer which can be capped once the landfill is considered full. The clay layer is expected to prevent heavy metals etc leeching into the local water supply.

        Landfill sites in Essex took most of London's waste for decades but are now running out of space and the price has gone up accordingly. Which is why loss making recycling can still be cheaper than burying it (I know that some recycling ends up being exported to China on otherwise empty cargo vessels, but I do not know how much).

        You could lower standards to make more sites viable, reduce the thickness of the clay layer, allow cheaper, less flexible materials to used etc. But that doesn't seem to be considered an option yet.

      You can recycle energy as well

      Manufacturing glass from raw materials is way more energy intensive than recycling it so by recycling glass you reduce the total energy required for manufacturing new glass things. In a sense, you're recycling the energy that was put into processing the raw materials into raw glass.

      Paper recycling, however, is more about saving the trees.

      1. Yet Another Anonymous coward Silver badge

        Re: You can recycle energy as well

        Paper recycling is about feeling like you are doing something and a little about landfill volume.

        The trees you are saving are farmed pine forests, more trees are planted for every one that is harvested - "saving them" is like recycling flour to save the wheat.

        It's horribly energy inefficient to collect and recycle paper and involves lots of nasty chemicals - but it is also expensive to bury large amounts of paper that never rots.

        1. Nigel 11

          Re: You can recycle energy as well

          Surely the best way to recycle low-grade paper is to burn it to generate green electricity? (CO2 goes up the chimney. New trees grow and absorb the CO2. The trees are made into paper and the cycle repeats)

          Landfilling paper generates methane by anaerobic decomposition. If that leaks into the atmosphere it's a rather more potent greenhouse gas than CO2. Yes, a well-built landfill site can trap the methane and feed it into a generator, which may be less polluting than burning paper directly -- but there's always going to be some methane leakage in that process.

        Re: You can recycle energy as well

        I'm not sure that's true about glass. Also factor shipping to one of few glass factories vs a nearer hole in ground. But Re-use of glass is certainly good?

        Also unlike doors, window frames and floors etc, trees for paper are planted especially to cut down later. Not all paper comes from trees though.

        Paper rots quite quicky. Glass never does, but you can crush it.

          Re: Paper rots quite quicky.

          Not in a modern land fill. And by modern, I mean pretty much anything after 1930. There was an archeology class that did a "dig" in a landfill. They pulled out readable newspapers from 1945.

          In an attempt to do away with the awkward smell of your typical dump, we've created zones where no decay mechanisms are at work. Clay lined pits, no drainage into the local water system, etc. It seems to me sensible garbage processing would find ways to easily extract the recyclable bits, then turn the rest into a sludge that you purposely decompose, possibly yielding other resources that while not directly profitable at least offset some of the cost of rendering the garbage into something that is more readily disposed. But again, its a game of price point numbers.

        A small amount of gold is used in almost every sophisticated electronic device. This includes: cell phones, calculators, personal digital assistants, global positioning system units and other small electronic devices. Most large electronic appliances such as television sets also contain gold.

        One challenge with the use of gold in very small quantities in very small devices is loss of the metal from society. Nearly one billion cell phones are produced each year and most of them contain about fifty cents worth of gold. Their average lifetime is under two years and very few are currently recycled. Although the amount of gold is small in each device, their enormous numbers translate into a lot of unrecycled gold.

    Energy return on investment.

    Yes there is a vast amount of resource under the ground. These can be divided fairly neatly into two - minerals that are used to build things /grow food, and minerals/liquids/gas used as a source of energy. Extracting anything from the ground uses energy. An energy source that use more energy to extract than it usefully provides is not an energy source, it is a sink. We may get to the point where drilling for oil is a net energy sink, because oil is so much more useful to society than coal, that we are prepared to still extract it using energy from coal at a net loss. However, we will never mine coal at a net energy loss. And coal is still the single biggest source of energy in the industrial world. All the easy sources of energy are mined first. That means, unless technology improves exponentially, the net energy from each KWh of energy extracted must decline, relentlessly, regardless of how much is under the ground. All the easy sources of all minerals are also mined first. They need ever larger amounts of energy for each Kg on mineral extracted over time, unless technology can improve exponentially. And the mining of energy needs ever more kg of minerals as people dig and drill deeper and further.

    So over time, we spend more and more energy extracting the same amount of minerals, and more and more energy and minerals extracting the same amount of energy. More and more of the global resources of both minerals and energy are used to keep the mining industry expanding, and less and less is left over for the rest of society.

    This is not sustainable. Long before the total energy budget peaks, industrial society peaks. Demand for the ever more expensive minerals and energy cannot be sustained, the price falls below that required to invest in further mines and oil fields in ever more extreme environments, and investment collapses. Then industrial society collapses.

    We are at that point. All the major private oil companies are way past peak production, and are cutting their capital budgets because they cannot find more oil to drill at an affordable price, even though the price rose FIVE FOLD in a decade.

    Yesterday, the official estimate of shale oil (as in fracking) resource in California was cut by 13 billion barrels, or 95%. That oil is still down there, but it is going to stay down there. For ever.

      "So over time, we spend more and more energy extracting the same amount of minerals, and more and more energy and minerals extracting the same amount of energy."

      This isn't true though. I agree that logically it should be. But we didn't first survey the entire world and then decide to mine the cheapest deposits. All much more random than that. For tin, for example, we mined Cornwall first, then the Krusny Hory (where I am now) which are both high energy requirement hard rock deposits. It's only in recent decades that we've been mining the alluvial deposits in Indonesia which are so low energy that you can (quite literally) pick up the tin ore and separate it from the beach sand with a vacuum cleaner electric motor.

      1. Perpetual Cyclist

        Re: Not quite

        Of course as industrial society expanded we found more and more resources of key minerals and even energy supplies. However, we have now surveyed the entire planet (apart from the deep oceans) and we have a very good idea of what is down there. Shale oil has been known about for 50 years or more, but it was only a five fold increase in price (and incremental technology improvements) that brought it on tap in the US. Production from that source will peak in the next 3 YEARS.

        Oil is the first major energy source to hit the buffers. It will not be the last. technology cannot outpace depletion for ever.

            Please don't laugh. We may even be able to get it working down here on Earth, if we really try hard enough. But if not, it's already working up there in the sky, keeping us all alive, and we now know how to harvest it. Just cover a smallish fraction of the Earth's deserts with solar panels (or with mirrors and systems for turning the capured heat into electricity - the jury is still out on whether solar-thermal might beat solar-PV).

            Solar power will be as good as it is today for a lot longer than the Earth will remain habitable.

            (BTW that's not a prediction of man-made eco-doom. It's just the fact that the sun is naturally getting hotter as it oh-so-slowly uses up its Hydrogen. The Earth will turn into a Venus clone a long time before Sol finally goes nova. Maybe as little as hundreds of My hence).

    Confirmation bias

    Confirmation bias.

    Confirmation bias.

    It needs repeating over and over again.

    Policy lobbyists genuinely believe what they say, and think they've seen the evidence.

    But the only evidence they see is the evidence they look for. And it doesn't have to be "arts graduates".

    It's the same for all sorts of areas.

    For nutrition . Because of a bias in nutritionists who don't seem to believe that food can be pleasurable, ( roughly summed up as if it's nice it must be bad for you).

    For Education, because of a grouping of policy makers who think that rote learning and slogging are the way to learn (Only phonics work. And we must have a lousy education system because we do poorly in a set of tests that is biased towards that type of slogging ).

    Health. I have a deep suspicion that the people who want to ban e-cigarettes work in this way. I've never smoked, but the claims of anti-ecigarette campaigners do seem to be based on desperately looking for reasons why these things can't be as good as they seem.

    And I'm sure many other areas too.

    Of course that could be my confirmation bias.

        I tried very hard to argue that we needed a target of every child eating f and v at least once every day. Which I thought was more important and attainable.

        I lost.

        Of course I lost.

        It had to be 5!

        Is every child eating 5-a-day or even close to that?

        What do you think?

        Is every child even eating *some* f and v every day? Only if their school works hard to make them - and since that was never the target.............

    Don't worry about this stuff, it will be banned first

    A greater problem than the resources running out is the materials being banned. This is on the cards with coal (was it here we had a report of a campagn to buy up all coal mines and close them?), and lead only survives in use because car batteries still need it. So what does it matter what coal is still under the ground? I am holding my breath waiting for zinc to be banned (like lead, it already is banned in paint).

    Never mind that exterior timber rots and steel rusts for want of creosote, lead primer and galvanising, or that energy prices are sky-rocketing and will go higher because we must susidise windmills and solar panels, and pay the Russians and Arabs for gas; the Greens will be happy.

    Certainly the UK running out of energy report, was about the LOCAL reserves, if International trade shutdown. E.g. The Ukraine became a east-west showdown.... The report SHOULD be a wake-up call to pollicy makers who assume business as usual has permanence!

    Second, true we will never "runout" of resources. But the price and the cost of extraction can change very rapidly.

    Third, one has to look at the timing supply chain adaptation. It has taken nearly a decade to restart the non-chinese rare-earth extraction supply chain. Converting refineries to changing raw materials...

    Shock, horror, Scargill was right - minerals no use without miners!

    We may well be "pretty much built on a bed of coal", but it's no use to us under the ground, and I can't see any future government reversing the Thatcher-orchestrated destruction of the mining industry, so we probably are going to 'run out' - in the sense of no longer producing any of our own - when the remaining few mines are tapped out in the fairly-near future.

      Re: Shock, horror, Scargill was right - minerals no use without miners!

      Oh for heaven's sake. Mrs T was not the primary cause of deep mining effectively ceasing in the UK. The cause was the development of efficient surface transport technology (mainly shipping) that allowed open cast coal from the US and Australia to be delivered to Europe at a price well below that of deep mined coal. If you want to persist in your belief that 'Fatcha dunnit' you need to explain why deep mining ceased in Germany (for example) at exactly the same time.

    "If you put the right doohicky on the side of this plant then you get the gallium out. It's at about 100ppm, 100 grammes per tonne of bauxite processed. Some 8,000 tonnes a year passes through those plants, which is useful because only a few of those BP plants have the doohickeys and globally we only use around 400 tonnes of gallium a year."

    100 g/t * 8,000 t/yr = 800,000 g/yr = 800 kg/yr = 0.8 t/yr of gallium with 100% doohickeys fitted.

    That's not going to cover 400t/yr. Have we lost or gained a thousand somewhere? Given that world-aluminium.org reports primary (i.e. non-recycled) Al production last month was 4,169 kt maybe that should 8,000 kt of bauxite a *month*? That would need only 5% doohickeys.

    Sadly, quite representative of a lot of green- endeavours

    Take a real problem, screw up the science, propose half-baked solutions.

    Get the politicians aboard. Screw things up some more.

    Just as an hypothesis, let's postulate that climate change, due to CO2 is a problem (I do think it is, but that doesn't matter to my argument). How do we respond?

    Germany - go all solar & wind. No more nukes. No more nukes. Oh, wait, that nasty little problem of needing to provide backup capacity to said renewables? I know, let's use brown coal for baseloads. Result: more CO2 and more expensive energy.

    US. Ethanol, ethanol. Corn-based, 1st gen. Save the planet. And it looks green too. Does it save CO2 over oil cradle-to-grave? Hmmm, no, but the farming states' voters are grateful for the $ubsidies.

    UK and its windfarms? Nice, but what about the intermittencies? No matter, it loooks green.

    Canada - I could probably get a subsidy for a Tesla S, if I had the cash to buy it. Good of all the taxpayers to chip in for my chick magnet, neh?

    If we ever get the public behind real CO2 limitation, the first thing to do is to _price_ CO2. I.e. tax it and offset other taxes downwards. Once dollars and cents get involved, the emperor's clothes will flutter away and people will find real solutions.

    Same thing with the metal shortages. Given a shortage, there will be more recycling, less use and more prospecting. Let it come.

    One exception being the Helium shortages the US govt might be running us into by forcing a premature cheap sell-off of what is admittedly their reserve. Politicians meddling again.

    Lots of sensationalism, as always in the news, but even with deadlines in the thousands of years, I find it scary. Does it mean that human civilization relying on technology is doomed at such a short term notice (in historical terms)? This eventual shortage of resource availability is certain of causing wars between countries on the scale that will make WWI and II look like how we look at some African or Balkans regional conflicts today, except it will be us involved directly, nor far away countries.

    We'll eventually need to remove the concept of countries and national governments, or to ensure there is a full cooperation and distribution of resources with no possibility of one country attacking another, or to go past the dependency on such metals and chemicals for a more sustainable technology, or some other solution to address the problem before it arises and takes catastrophic proportions.

      The Great Horse Manure Crisis is a great example of an insoluble problem that was actually solved. When it comes to resource depletion then you've got recycling first and foremost (if you absolutely cannot mine many new materials then the cost of mining goes up then recycling the already mined stuff gets more viable)

      Plus, given that our currant rate of scientific advancement over the last century, I suspect that in several thousand years a future civilisation might create scarce materials with nano technology or something similar.

      Disruption

      Coal in UK maybe hasn't been Globally competitive since early 1900s. During WWI and WWII it was important and production increased as fuel was hard to import. In 1920s a lot of miners unemployed. Mines have closed not because coal is exhausted but it's not competitive and not the demand there once was (Town Gas used to be made from coal).

      There might even be several 1000 years of coal in UK. It depends how badly it's wanted. Coal now is out of favour. If there was no oil and gas you can be sure non-polluting Coal power stations and Gas production would be built. Meanwhile the Arab strangle-hold on Oil and Russian on Gas in Europe may be broken in a year or two as more shale & fracking comes online. USA may be net exporter rather than importer.

      DISRUPTIVE TECH

      Maybe solar energy will be deployed on African coast to make LPG from sea water and waste carbon, which can be then more easily/cheaply transported long distance than Electricity or Hydrogen. Or the problem of harnessing Fusion will be solved.

      I don't think we are due to run out of anything even in our Grandchildren's life.

    What you have to remember is that an Arts graduate doesn't have to know 'facts' as such (yes to a limited degree but wait a moment longer). They have to know how to present what facts they do know to successfully create a theory that matches those facts. ie its all about the spin.

    Arts Graduates are good at spin.

    Understanding a topic takes time to learn. Most people are more interested in hockey then working hard to understand something. So people listen to the spin, and believe it.

    But that's too narrow a definition of "resources", just to talk about elements or even compounds. Here are some resources of special interest to me, as hobby of stone carving and jewellery.

    Spoiler alert: if your only definition of value is to weigh the stuff, then yes we have plenty. But for much of the real world, that rather misses the point.

    Blue John fluorite. Only two sources known: classic Derbyshire mine is finished. There is NO MORE. Fragments, but if you want to carve a small bowl like those that were done a century back, you are out of luck. There is a Chinese mine, and it is nice, but just not the same - not as veined and decorative.

    Alabaster. The largest and best quality mines are all mined out. You can still get good quality stuff, but only relatively small chunks now. "The ancients" had access to fault-free chunks at multi cubic meter sizes, and there are existing sculptures to prove it. Now, at whatever price, to get a single fault free cubic meter is no longer possible. There just aren't any left.

    Marble - not as extreme as alabaster, but we are starting to suck the dregs on top quality vast chunks. Kitchen work tops, fine. If you wanted to carve Michelangelo's Slaves out of top quality Carrara, tough. You live three centuries too late, you missed your chance.

    Diamonds. These are plentiful, made rare only by monopoly. But if you want a flawless 1000+ carat, the last of those was found in 1905 (cullinan). Despite the total diamond mining throughput being orders of magnitude greater now, the goodput of vast diamonds dropped through the floor nearly a century ago.

    Good quality nephrite jade. Hundreds of tonnes plentifully available still mined. But by comparison to classic sources, small and flawed. Only useful for tiny dragons now.

    Emeralds. Modern emeralds of significant size AT ANY PRICE are basically shitty, flawed and with lousy colour. I have some old photos of my grandmothers emerald necklace. Central stone 30 carat flawlesst, plus another 20 carats in medium size stones. Today - that would buy palaces. Then, a middle class woman could wear it on an evening out.

      @just the facts

      there are still good quality gems out there - its partly the extraction methods that cause fault.

      OK big diamonds were naturally sorted and lying around on or near the surface* - possibly similar for emeralds. But extraction methods for big hunks of jade are not suitable for making a profit from large deposits of poor jade so the good quality stuff comes up in small hunks. Making things cheap - well makes things cheap!

      *though maybe there are large quantities of good quality stones in vaults to keep the price high!
