    1. Eine Empfehlung des Zusammenschlusses nationaler Akademien der Wissenschaften und eine zusammenfassende Studie zum globalen Plastiksystem empfehlen die Reduktion des Verbrauchs um 50% und eine Reihe weiterer Schritte wie das fast vollständige Recycling von Plastik und die Produktion aus Biomaterialien. Anlass sind die Verhandlungen zum internationalen Plastikabkommen. Plastikproduktion und Verbrauch führen schon jetzt – abgesehen von zahlreichen anderen negativen Folgen – zu Emissionen von ca einer Gigatonne CO2 im Jahr. Ohne drastische Änderungen wird sich diese Menge vervielfachen. https://www.derstandard.de/story/3000000205422/wissenschaft-fordert-radikale-abkehr-von-herkoemmlicher-plastikproduktion

    1. in general countries tend to excavate enormous volumes of earth and this earth is incredibly considered as a waste material

      for - circular economy - building - excavation waste - circular economy - construction - excavation waste - key insight - repurpose excavation waste as building material

      key insight - She makes an pretty important observation about the inefficiency of current linear construction process - The excavation part requires enormous amounts of energy, and the earth that is excavated is treated as waste that must be disposed of AT A COST! - Instead, with a paradigm shift of earth as a valuable building resource, the excavation PRODUCES the building materials! - This is precisely what BC Material's circular economy business model is and it makes total sense!<br /> - With a simple paradigm and perspective shift, waste is suddenly transformed into a resource! - waste2resource - waste-to-resource

      new meme - Waste-2-Resource

    1. for - circular economy - kitchen - circular economy - furniture - circular kitchen - Stykka - modular furniture

      comment - sadly, it's not open source, but this is to be expected with most mainstream businesses. - the problem is in trying to protect one's IP and look after self-interest, it scales very slowly. - we need open-source, circular economy, open-source, circular furniture and open-source circular kitchen

    1. "There's so much pressure and emphasis on getting the Green Revolution happening that it's almost by any means necessary without that pause of 'well it is green, but is it as green as it should be?"

      Circular Economy for the Energy Transition

    1. first thing's first is we reorder the vital industrial hubs. 00:38:13 Now yes, those industrial hubs will actually have to have decision makers what considers a vital hub. What's a vital activity? Then we need the people to actually operate those in industrial services. So you'll have a population inserted. Around that population, we have our food production and it all has to be local. So you have now a series of localized, decentralized networks that are actually, you'll have a 00:38:39 hub where everything balances, but in a local area.

      !- alignment : Michaux's vision of industrial transformation and many others working in the commons - relocalization, dense local circular economies, community owned for democratization of production - in addition, commons theory of cosmolocal production networks all these relocalized dense production hubs together for information sharing efficacy

    2. there's an order to do things in. And so the first order of business was to reshuffle and reorder our industry sites around energy hubs. Where is their energy coming from? 00:35:16 And if we can't project it over such a long period of time, over a long distance anymore, how do we reorder our industry where each industrial site will be attached to other sites, where they function almost like an industrial version of an organic farm. The outputs of one industry unit and its waste plume inputs to another industrial unit, and 00:35:44 they're all attached to the same energy system.

      !- overview : restructuring industry around an energy constrained future - redesign for circular colocated factory networks - output waste streams of one plant feeds input feedstock of nearby plants - relocalize to minimze unnecessary transportation

    1. To avoid the worst case scenario, we need to embrace the circular economy of "repair, redesign, reuse" to reach net zero.

    1. Sewage sludge is commonly used on agricultural land as a sustainable and renewable source of fertiliser throughout European countries, in part due to EU directives that promote the diverting of sewage sludge away from landfill and incineration and towards energy production and agriculture.

      This EU directive led to the spread of the unintended consequence.

    2. the team estimate that microplastics removed from raw sewage at wastewater treatment plants go on to make up roughly 1% of the weight of sewage sludge, which is commonly used as a fertiliser on farms across Europe.

      This case illustrates the potential unintended consequences from attempting to do good.

      This is a classic example of how progress traps occur.

      Capturing nutrients in waste water closes a nutrient waste loop and seems a good example of applying circular economy thinking.

      HOWEVER, at the time the decision was made to process sewage sludge into fertilizer ignored the relationship of sludge to microplastics was unknown or insufficiently explored. After the decision was made, the practice was adopted across many countries in the EU. After years of practice, the new knowledge reveals that there has been years of silent microplastic contamination. To fix the solution will require another solution, perhaps even more complex..

      This illustrates the danger of applying circular economy techniques when the waste stream is not fully characterized.

    1. What can we do with a shift in thinking backed by a total of $3.6 trillion in funds under management? I’m backing strategic circular initiatives to convert the highest return on value for anyone’s money. Stay tuned as we crack open new investment opportunities.

      Her diagram explicitly shows a synthesis of planetary boundaries and circular economy. This is a connection that many in this area are tacitly aware of but is good to explicate it in a diagram of this sort..

      If circular economy is about ultimate reuse and recirculating material flows to eliminate the concept of waste, then how does energy consumption fit into the picture? Obviously, CO2 emissions is a form of material waste that is an undesirable byproduct of carbon-based energy usage. Capturing CO2 and reusing it is one method, but not a very scalable solution presently.

    1. For four years, an accelerated and intensive global effort will be made to reduce greenhouse gas emissions and restore ecological stability. It will be “fast and furious” because it will involve startup action as well as implementation. It is focused on the remaining “low-hanging fruit” for fastest global reductions

      The Tipping Point Festival can introduce the Bend-the-Curve (BtC) gamification to engage as many cities, towns, rural communities and bioregions as possible. A 3 year research program to dis-aggregate planetary boundaries can allocate a fairshare of local biophysical targets each city, town, rural community and bioregion must aim to achieve if we as a civilization are to meet the 1.5 deg C target, as well as other Anthropocene and planetary boundary targets.

      Doughnut economic framework can be adopted immediately and educated across all communities to plant seeds of local change actor chapters who can start their own local doughnut economies and begin reshaping their local economy into circular bio WEconomies.

      When the dis-aggregated planetary boundary metrics are available, then each community can adopt and aim to bend their local curve, in order that we altogether bend the global curves back to a safe operating space.

      it may be questionable whether we are able to develop highly accurate targets, but even if we are close enough, the greater value is to allow citizens to have a tangible and compelling and measurable reason to work together, organize and mitigate our human impacts in a systematic way. In this way, we can expose the hyperthreat by breaking it down into digestable, identifiable pieces that are cognitively more accessible and can lodge into the salience landscape of the individuals of a community.

    1. decarbonization also creates opportunities, and investors are keen to put capital to work on these areas. Many of them directly involve, or are adjacent to, chemicals production, including battery materials, green hydrogen, and materials that can enable energy efficiency.

      Circular economies are good news for everyone
