    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
