In this narrated slideshow, McKinsey alumnus Markus Zils explains how the circular economy encourages companies to seek ways of retaining more of the value of the material, energy, and labor inputs that go into their products.
Circular economy thinking is throwing up some fascinating dynamics right now. The urgent need for systems-level redesign requires an experimental cocktail of innovation and imagination, not to mention open platform dialogue and collaboration.
Different European regions have very different diets and environmental conditions, meaning their water consumption varies widely. Despite this, switching to vegetarian diets in keeping with regional variation would substantially reduce water consumption in all areas, a new study co includes. Where people choose to eat meat, adopting a healthy diet low in oils and sugar will also reduce water consumption, although to a lesser degree.

Processed foods are notorious for their jaw-droppingly long lists of chemical-laden ingredients, each one sounding worse than the last. But as these detailed infographics show, even the simplest of foods are anything but.
Even today's best rechargeable lithium batteries do lose their ability to hold a charge after a while, and are considered toxic waste once discarded. In just a few years, however, they may be replaced by batteries that are refillable and biodegradable, and that will also have a higher energy density yet a lower price ... and they'll run on sugar.
"Sugar is a perfect energy storage compound in nature," says Virginia Tech's Prof. Y.H. Percival Zhang, who is leading the research. "So it's only logical that we try to harness this natural power in an environmentally friendly way to produce a battery."
Zhang's isn't the first experimental sugar battery, although he claims that its energy density is "an order of magnitude higher than others."
It's actually a type of enzymatic fuel cell. For fuel, it utilizes maltodextrin, which is a polysaccharide made from the hydrolysis of starch (polysaccharides are chains of sugars). The catalyst in its anode is made from inexpensive enzymes, as opposed to the costly platinum that's used in regular batteries.
When the maltodextrin is combined with air, water and electricity are produced. Unlike the case with a hydrogen fuel cell, however, the sugar battery is non-explosive and non-flammable.
Zhang envisions users refilling the batteries with sugar when they need refueling, "much like filling a printer cartridge with ink." He hopes that they may be powering electronic devices in as little as three years.
Tweet Tweet 3D printers have been around for a while now. Their prices are slowly coming down. Some people are still not sure what they can do with a 3D printer though. 3D printers can print food, human tissue, plastic, and other material.
