To build a circular economy, we need to put recycling in the bin
Recycling is linear, but the economy shouldn't be.

Too often the concept of a circular economy is muddled up with some kind of advanced recycling process that would mean keeping our industrial system as it is and preserving a growing consumption model.
This idea is based on a belief that recycling will take care of everything.
One of the most startling examples of this is the part of the European Union's Circular Economy Action Plan which aims to increase recycling rates: up to 70% of all packaging waste by 2030 and 65% of all municipal waste by 2035. In a properly built circular economy, one should rather focus on avoiding the recycling stage at all costs. It may sound straightforward, but preventing waste from being created in the first place is the only realistic strategy.
While we obviously need to continue recycling for quite some time, putting the emphasis on genuine circular innovations – that is, moving us away from a waste-based model – should be our sole objective.
Recycling is linear
In a linear economy, we do not account for the side-effects generated by a product once sold to an end customer. The aim is to sell a maximum number of products at minimal cost. Continuous pressure to reduce costs leads to the creation of many of these side-effects – called externalities by economists. The higher a company's rate of production and the higher its efficiency, the more successful it will be at selling its goods in a fiercely competitive environment.
What is a circular economy?
This worked well in the 20th century when resources were easily available and raw material prices kept decreasing. Waste, as an economic externality, was not the producers' responsibility. Managing waste cycles, dumping it out of sight or, at best, recycling it – but only when it was cost-effective – were under the control of our national institutions.
Visionary manufacturers, who understand the upcoming challenges of increasing their economic resilience, know better: a product that is returned for repair will cost less to fix and sell again, than manufacturing it from scratch.
In our current model, we extract resources, transform them into products, and consume or use them, prior to disposing of them. Recycling only starts at the throwing-away stage: this is a process that is not made to preserve or increase value nor to enhance materials.
We need to understand that recycling is not an effective strategy for dealing with unused resource volumes in a growth model. We will find ourselves in a never-ending pursuit of continuously generated waste, rather than seeing the avoidance of waste as a path to beneficial innovations on many levels.
Of course, it is easier to think about recycling. This avoids changing the whole of our volume-based production model. But in a world where we have to shift our consumption patterns and use less energy, recycling no longer has all the answers.
Recycling is 'business-as-usual'
Since we cannot stop the volume of waste overnight, investments in the recycling industry are needed. But truly meaningful investment in developing a circular economy takes place outside of the recycling space. Indeed, the more we recycle and the more we finance recycling factories, the more we stay 'linear'. We mistakenly believe this is the best route to solve our problems - but by staying in a recycling-based economy, we will delay the transition to an advanced circular economy.
In a circular economy, resources do not end up as recyclables since products are made to last several lifecycles. Products' lifespans are extended via maintain, repair, redistribute, refurbishment and/or re-manufacture loops, thus they never end up in the low-value, high-need-for-energy loop: recycling.
We live in a world in dire need of disruptive innovations. Closing loops next to where customers live while avoiding waste is a short and longer-term win-win for any leading re-manufacturer. Short-term because you are in direct contact with your customers, and taking back a product that needs maintenance is an opportunity to better understand their needs and help them with additional services. Long-term because you will lower your exposure to future financial risks. Any of the feedback loops that exist prior to the recycling loop are an opportunity to take back control over your stock of resources – taking control away from the raw material markets, which may become highly volatile. Increased interactions with your customers, both commercial and financial, and an in-depth understanding of their needs, would increase customer loyalty and a business' overall resilience.
Re-using, re-distributing and/or remanufacturing strategies are the preferred approaches in a circular economy, as they are based on parts durability. Caring for and preserving the value of product components increases corporate economic resilience, while diminishing external market risks. Whether you are acting in a highly advanced or a developing economy, these strategies make crystal-clear sense: they are less costly in the long-run because repairing a product made to last is always less expensive than producing it from scratch.
Leapfrogging into valued supply chains
Following this approach, we must move away from activities that devalue the material, such as recycling, and instead invest in those activities that preserve it: reuse and remanufacture. These two are especially important since they create many more secure jobs. Walter R. Stahel, the godfather of the modern circular economy, introduced the metric of labor input-per-weight ratio (man-hour-per-kg, or mh/kg) to measure job creation in relation to resource consumption. He found that the ratio of mh/kg when building a remanufactured engine from used resources compared to making the same engine from virgin materials is 270:1. The impact on employment is huge.
The re-localization and the re-sizing of activities closer to customers become critical. Production sites should migrate from a highly centralized global hub to units designed to fulfill local needs. In developed markets, a possible plan could be to develop strategic partnerships with local service providers, who can provide the infrastructure. In emerging markets, where there is often an urgent need for jobs, leapfrogging straight into a national re-manufacturing strategy is the way forward. Becoming the next 'world factory' hub is an obsolete vision today.
One way to start thinking like a leader in the next economy while creating jobs could be in order of priority:
- Reuse by repairing (goods) through re-hiring (people), while sharing the radical benefits (awareness) of such a model
- Redistribute by promoting access (goods) through collaboration (people), while sharing information (awareness) about this model
- Remanufacture via the ease of disassembly (goods) by training (people), while sharing the acquired knowledge (awareness) through this model
- Migration of recycling activities by diverting (goods) to service models, transferring skills (people) to remanufacturing processes (awareness).
All of the above make sense in a world where planetary limits have already hit most economies.
Adopting a circular strategy by avoiding reliance on recycling is the way forward.
This is about genuine innovation derived from genuine leadership.

No, the Yellowstone supervolcano is not ‘overdue’
Why mega-eruptions like the ones that covered North America in ash are the least of your worries.
Ash deposits of some of North America's largest volcanic eruptions.
- The supervolcano under Yellowstone produced three massive eruptions over the past few million years.
- Each eruption covered much of what is now the western United States in an ash layer several feet deep.
- The last eruption was 640,000 years ago, but that doesn't mean the next eruption is overdue.
The end of the world as we know it

Of the many freak ways to shuffle off this mortal coil – lightning strikes, shark bites, falling pianos – here's one you can safely scratch off your worry list: an outbreak of the Yellowstone supervolcano.
As the map below shows, previous eruptions at Yellowstone were so massive that the ash fall covered most of what is now the western United States. A similar event today would not only claim countless lives directly, but also create enough subsidiary disruption to kill off global civilisation as we know it. A relatively recent eruption of the Toba supervolcano in Indonesia may have come close to killing off the human species (see further below).
However, just because a scenario is grim does not mean that it is likely (insert topical political joke here). In this case, the doom mongers claiming an eruption is 'overdue' are wrong. Yellowstone is not a library book or an oil change. Just because the previous mega-eruption happened long ago doesn't mean the next one is imminent.

This map shows the location of the Yellowstone plateau and the ash beds deposited by its three most recent major outbreaks, plus two other eruptions – one similarly massive, the other the most recent one in North America.
Huckleberry Ridge
The Huckleberry Ridge eruption occurred 2.1 million years ago. It ejected 2,450 km3 (588 cubic miles) of material, making it the largest known eruption in Yellowstone's history and in fact the largest eruption in North America in the past few million years.
This is the oldest of the three most recent caldera-forming eruptions of the Yellowstone hotspot. It created the Island Park Caldera, which lies partially in Yellowstone National Park, Wyoming and westward into Idaho. Ash from this eruption covered an area from southern California to North Dakota, and southern Idaho to northern Texas.
Mesa Falls
About 1.3 million years ago, the Mesa Falls eruption ejected 280 km3 (67 cubic miles) of material and created the Henry's Fork Caldera, located in Idaho, west of Yellowstone.
It was the smallest of the three major Yellowstone eruptions, both in terms of material ejected and area covered: 'only' most of present-day Wyoming, Colorado, Kansas and Nebraska, and about half of South Dakota.
Lava Creek
The Lava Creek eruption was the most recent major eruption of Yellowstone: about 640,000 years ago. It was the second-largest eruption in North America in the past few million years, creating the Yellowstone Caldera.
It ejected only about 1,000 km3 (240 cubic miles) of material, i.e. less than half of the Huckleberry Ridge eruption. However, its debris is spread out over a significantly wider area: basically, Huckleberry Ridge plus larger slices of both Canada and Mexico, plus most of Texas, Louisiana, Arkansas, and Missouri.
Long Valley
This eruption occurred about 760,000 years ago. It was centered on southern California, where it created the Long Valley Caldera, and spewed out 580 km3 (139 cubic miles) of material. This makes it North America's third-largest eruption of the past few million years.
The material ejected by this eruption is known as the Bishop ash bed, and covers the central and western parts of the Lava Creek ash bed.
Mount St Helens
The eruption of Mount St Helens in 1980 was the deadliest and most destructive volcanic event in U.S. history: it created a mile-wide crater, killed 57 people and created economic damage in the neighborhood of $1 billion.
Yet by Yellowstone standards, it was tiny: Mount St Helens only ejected 0.25 km3 (0.06 cubic miles) of material, most of the ash settling in a relatively narrow band across Washington State and Idaho. By comparison, the Lava Creek eruption left a large swathe of North America in up to two metres of debris.
The difference between quakes and faults
The volume of dense rock equivalent (DRE) ejected by the Huckleberry Ridge event dwarfs all other North American eruptions. It is itself overshadowed by the DRE ejected at the most recent eruption at Toba (present-day Indonesia). This was one of the largest known eruptions ever and a relatively recent one: only 75,000 years ago. It is thought to have caused a global volcanic winter which lasted up to a decade and may be responsible for the bottleneck in human evolution: around that time, the total human population suddenly and drastically plummeted to between 1,000 and 10,000 breeding pairs.

So, what are the chances of something that massive happening anytime soon? The aforementioned mongers of doom often claim that major eruptions occur at intervals of 600,000 years and point out that the last one was 640,000 years ago. Except that (a) the first interval was about 200,000 years longer, (b) two intervals is not a lot to base a prediction on, and (c) those intervals don't really mean anything anyway. Not in the case of volcanic eruptions, at least.
Earthquakes can be 'overdue' because the stress on fault lines is built up consistently over long periods, which means quakes can be predicted with a relative degree of accuracy. But this is not how volcanoes behave. They do not accumulate magma at constant rates. And the subterranean pressure that causes the magma to erupt does not follow a schedule.
What's more, previous super-eruptions do not necessarily imply future ones. Scientists are not convinced that there ever will be another big eruption at Yellowstone. Smaller eruptions, however, are much likelier. Since the Lava Creek eruption, there have been about 30 smaller outbreaks at Yellowstone, the last lava flow being about 70,000 years ago.
As for the immediate future (give or take a century): the magma chamber beneath Yellowstone is only 5 percent to 15 percent molten. Most scientists agree that is as un-alarming as it sounds. And that its statistically more relevant to worry about death by lightning, shark, or piano.

Smartly dressed: Researchers develop clothes that sense movement via touch
Measuring a person's movements and poses, smart clothes could be used for athletic training, rehabilitation, or health-monitoring.
In recent years there have been exciting breakthroughs in wearable technologies, like smartwatches that can monitor your breathing and blood oxygen levels.
But what about a wearable that can detect how you move as you do a physical activity or play a sport, and could potentially even offer feedback on how to improve your technique?
And, as a major bonus, what if the wearable were something you'd actually already be wearing, like a shirt of a pair of socks?
That's the idea behind a new set of MIT-designed clothing that use special fibers to sense a person's movement via touch. Among other things, the researchers showed that their clothes can actually determine things like if someone is sitting, walking, or doing particular poses.
The group from MIT's Computer Science and Artificial Intelligence Lab (CSAIL) says that their clothes could be used for athletic training and rehabilitation. With patients' permission, they could even help passively monitor the health of residents in assisted-care facilities and determine if, for example, someone has fallen or is unconscious.
The researchers have developed a range of prototypes, from socks and gloves to a full vest. The team's "tactile electronics" use a mix of more typical textile fibers alongside a small amount of custom-made functional fibers that sense pressure from the person wearing the garment.
According to CSAIL graduate student Yiyue Luo, a key advantage of the team's design is that, unlike many existing wearable electronics, theirs can be incorporated into traditional large-scale clothing production. The machine-knitted tactile textiles are soft, stretchable, breathable, and can take a wide range of forms.
"Traditionally it's been hard to develop a mass-production wearable that provides high-accuracy data across a large number of sensors," says Luo, lead author on a new paper about the project that is appearing in this month's edition of Nature Electronics. "When you manufacture lots of sensor arrays, some of them will not work and some of them will work worse than others, so we developed a self-correcting mechanism that uses a self-supervised machine learning algorithm to recognize and adjust when certain sensors in the design are off-base."
The team's clothes have a range of capabilities. Their socks predict motion by looking at how different sequences of tactile footprints correlate to different poses as the user transitions from one pose to another. The full-sized vest can also detect the wearers' pose, activity, and the texture of the contacted surfaces.
The authors imagine a coach using the sensor to analyze people's postures and give suggestions on improvement. It could also be used by an experienced athlete to record their posture so that beginners can learn from them. In the long term, they even imagine that robots could be trained to learn how to do different activities using data from the wearables.
"Imagine robots that are no longer tactilely blind, and that have 'skins' that can provide tactile sensing just like we have as humans," says corresponding author Wan Shou, a postdoc at CSAIL. "Clothing with high-resolution tactile sensing opens up a lot of exciting new application areas for researchers to explore in the years to come."
The paper was co-written by MIT professors Antonio Torralba, Wojciech Matusik, and Tomás Palacios, alongside PhD students Yunzhu Li, Pratyusha Sharma, and Beichen Li; postdoc Kui Wu; and research engineer Michael Foshey.
The work was partially funded by Toyota Research Institute.

Do you worry too much? Stoicism can help
How imagining the worst case scenario can help calm anxiety.
Stoicism can help overcome anxiety
- Stoicism is the philosophy that nothing about the world is good or bad in itself, and that we have control over both our judgments and our reactions to things.
- It is hardest to control our reactions to the things that come unexpectedly.
- By meditating every day on the "worst case scenario," we can take the sting out of the worst that life can throw our way.
Are you a worrier? Do you imagine nightmare scenarios and then get worked up and anxious about them? Does your mind get caught in a horrible spiral of catastrophizing over even the smallest of things? Worrying, particularly imagining the worst case scenario, seems to be a natural part of being human and comes easily to a lot of us. It's awful, perhaps even dangerous, when we do it.
But, there might just be an ancient wisdom that can help. It involves reframing this attitude for the better, and it comes from Stoicism. It's called "premeditation," and it could be the most useful trick we can learn.
Practical Stoicism
Broadly speaking, Stoicism is the philosophy of choosing your judgments. Stoics believe that there is nothing about the universe that can be called good or bad, valuable or valueless, in itself. It's we who add these values to things. As Shakespeare's Hamlet says, "There is nothing either good or bad, but thinking makes it so." Our minds color the things we encounter as being "good" or "bad," and given that we control our minds, we therefore have control over all of our negative feelings.
Put another way, Stoicism maintains that there's a gap between our experience of an event and our judgment of it. For instance, if someone calls you a smelly goat, you have an opportunity, however small and hard it might be, to pause and ask yourself, "How will I judge this?" What's more, you can even ask, "How will I respond?" We have power over which thoughts we entertain and the final say on our actions. Today, Stoicism has influenced and finds modern expression in the hugely effective "cognitive behavioral therapy."

One of the principal fathers of ancient Stoicism was the Roman statesmen, Seneca, who argued that the unexpected and unforeseen blows of life are the hardest to take control over. The shock of a misfortune can strip away the power we have to choose our reaction. For instance, being burglarized feels so horrible because we had felt so safe at home. A stomach ache, out of the blue, is harder than a stitch thirty minutes into a run. A sudden bang makes us jump, but a firework makes us smile. Fell swoops hurt more than known hardships.
What could possibly go wrong?
So, how can we resolve this? Seneca suggests a Stoic technique called "premeditatio malorum" or "premeditation." At the start of every day, we ought to take time to indulge our anxious and catastrophizing mind. We should "rehearse in the mind: exile, torture, war, shipwreck." We should meditate on the worst things that could happen: your partner will leave you, your boss will fire you, your house will burn down. Maybe, even, you'll die.
This might sound depressing, but the important thing is that we do not stop there.
Stoicism has influenced and finds modern expression in the hugely effective "cognitive behavioral therapy."
The Stoic also rehearses how they will react to these things as they come up. For instance, another Stoic (and Roman Emperor) Marcus Aurelius asks us to imagine all the mean, rude, selfish, and boorish people we'll come across today. Then, in our heads, we script how we'll respond when we meet them. We can shrug off their meanness, smile at their rudeness, and refuse to be "implicated in what is degrading." Thus prepared, we take control again of our reactions and behavior.
The Stoics cast themselves into the darkest and most desperate of conditions but then realize that they can and will endure. With premeditation, the Stoic is prepared and has the mental vigor necessary to take the blow on the chin and say, "Yep, l can deal with this."
Catastrophizing as a method of mental inoculation
Seneca wrote: "In times of peace, the soldier carries out maneuvers." This is also true of premeditation, which acts as the war room or training ground. The agonizing cut of the unexpected is blunted by preparedness. We can prepare the mind for whatever trials may come, in just the same way we can prepare the body for some endurance activity. The world can throw nothing as bad as that which our minds have already imagined.
Stoicism teaches us to embrace our worrying mind but to embrace it as a kind of inoculation. With a frown over breakfast, try to spend five minutes of your day deliberately catastrophizing. Get your anti-anxiety battle plan ready and then face the world.

Study: People will donate more to charity if they think something’s in it for them
A study on charity finds that reminding people how nice it feels to give yields better results than appealing to altruism.
