A circular economy is an industrial system that is restorative or regenerative by intention and design. It replaces the end-of-life concept with restoration, shifts towards the use of renewable energy, eliminates the use of toxic chemicals, which impair reuse and return to the biosphere, and aims for the elimination of waste through the superior design of materials, products, systems and business models.
For technical nutrients, the circular economy largely replaces the concept of a consumer with that of a user. This calls for a new contract between businesses and their customers based on product performance. Unlike in today’s buy-and-consume economy, durable products are leased, rented or shared wherever possible. If they are sold, there are incentives or agreements in place to ensure the return and thereafter the reuse of the product or its components and materials at the end of its period of primary use.
The power of the inner circle refers to minimizing comparative materials use vis-à-vis the linear production system. The tighter the circle, i.e. the less a product has to be changed in reuse, refurbishment and remanufacturing and the faster it returns to use, the higher the potential savings on the shares of material, labour, energy and capital still embedded in the product, and the associated externalities (such as greenhouse gas (GHG) emissions, water and toxicity).
The power of circling longer refers to maximizing the number of consecutive cycles (be it repair, reuse, or full remanufacturing) and/or the time in each cycle. Each prolonged cycle avoids the material, energy and labour of creating a new product or component.
The power of cascaded use refers to diversifying reuse across the value chain.
2018/09/10: microgrids as the end result the combination of several technological trends, namely, rooftop solar, electric vehicles, heat pumps and batteries for storage. The key is that these technologies are decentralized—they can easily be owned by consumers and cooperatives in local systems.
Currently the way in which we use these technologies is, in his words, “dumb.” We simply attach solar panels, heat pumps, and electric vehicles to the grid for their own separate purposes. This dramatically increases the load on the local grid, requiring costly infrastructure upgrades to sustain the system.
The report simulated what would happen if the Ardehuizen implemented an intelligently managed microgrid with more sophisticated local supply and demand mechanisms.
These would entail a whole suite of interconnected technologies: a community battery storage system, smart meters which actively monitor the entire system, air-to-water heat pumps intelligently managed according to actual demand, local energy trading between the houses so they can exchange surplus, more electric vehicles, the use of Combined Heat and Power (CHP) units which generate both heat and electricity using biomass, and the installation of a local district heating network to distribute heat to multiple houses.
this could well represent only the beginning of what is possible. The end-goal of the Metabolic team’s technology research is a concept called “Smarthoods.”
The project aims to design an urban system which integrates decentralised food, water and energy flows in order to create a nearly fully self-sufficient neighbourhood.
It works based on the principle of “circularity”—recycling water, materials, and waste as much as possible within the system.
2015/12/02: circular economy will boost the EU's competitiveness by protecting businesses against scarcity of resources and volatile prices, helping to create new business opportunities and innovative, more efficient ways of producing and consuming.
It will create local jobs at all skills levels and opportunities for social integration and cohesion. At the same time, it will save energy and help avoid the irreversible damages caused by using up resources at a rate that exceeds the Earth's capacity to renew them in terms of climate and biodiversity, air, soil and water pollution.
Action on the circular economy therefore ties in closely with key EU priorities
2018-09-08: To produce a gold ring today, up to 30 tonnes of waste is created. This includes toxic waste such as cyanide, mercury, and sulphuric acid, which then finds its way into the world’s oceans, lakes, and rivers. Ten years ago, up to ten times less waste was created because the quality of ore was higher. Today, there is more gold in one tonne of waste electricals than there is in one tonne of ore. We need to be recovering this gold from waste before mining virgin ore.

Precious Plastic started 5 years ago and has grown into a big community of enthusiastic people aroundrnthe world recycling plastic. Over 200 plastic recycling workspaces have already been set up and arnnew one is opening up somewhere around the world every week. This is great and keeps expanding.rnHowever, the plastic problem is still way, way bigger than us- most of the plastic is still laying aroundrnas waste. We can do more. Specially looking out our map with +6000 people from around the worldrnwanting to get started. Until now Precious Plastic is hacked together with minimal resources thanks tornthe help of people around the world. It is now time to step up our game and get more professional (atrnleast a bit :). We have been gathering feedback and shaping a plan for a new version. Precious Plastic
Customers say they want brands to be more environmentally conscious - but eco-friendly marketing campaigns fall flat.

What would it take to make the fashion industry truly sustainable?
Fablabs, makerspaces, emerging global knowledge commons... These are but some of the outcomes of a growing movement that champions globally-sourced designs for local economic activity. Its core idea is simple: local ownership of the means to produce basic manufactures and services can change our economic paradigm, making our cities self-sufficient and help the planet.
The current state of worldwide urban development is depressing. We are not moving towards environmentally sustainable design and reduced consumption quickly enough. There have been dire warnings about
Jamadda, l'ecovillaggio in Giamaica nato dal sogno di un'italiana, è diventato una delle più rilevanti avanguardie del cambiamento di tutta l'isola.
Medha Tadpatrikar helped design a machine in Pune, India, that heats up plastic to convert it to fuel. The process is eco-friendly in more ways than one.
'The Real Circular Economy' studies how relocalising production with not-for-profit business models helps build resilient and prosperous societies
J. B. MacKinnon on how the durability of light-emitting diodes challenges the economics of planned obsolescence.
Reading the previous post you may have thought: Okay, so perma-circularity is about circularity and permanence -- about recycling, reusing, re-manufacturing, repairing, and reducing -- but what does it consist in? Isn't it some sort of neo-primitivist pipe dream? Do we really need to reduce? Why have zero or near-zero growth? Surely engineers nowadays are
We need a genuinely circular metabolism, and that can only be a self-maintaining circle - one that doesn't spiral outward.
