Circle Economy and ICLEI have partnered up to initiate the go to knowledge hub of case studies about the circular economy in cities. The Cities Collection is a repository of case studies that demonstrate the role of cities in the circular transition, and includes policies, business cases and research articles. Cases in the Collection flow into an ecosystem of digital products which support users in transitioning cities to circularity, for example [Ganbatte](https://ganbatte.world/cities/) and <a href="https://circulars.iclei.org/" target="_blank">ICLEI Circulars</a>, both part of the <a href="https://circulars.iclei.org/circle-lab-for-cities/" target = _blank">Circle Lab for Cities Programme.</a>

Regenerate strategies phase out hazardous or toxic materials and processes and substitute them with regenerative biomass resources. A circular economy aims to mimic natural cycles—by shifting to more regenerative farming practices, for example—while also maximising the share of circular biomass that enters the economy. Regeneration can happen both at the systems level (by designing regenerative processes) as well as at the product level (by switching synthetic to organic fertilisers, for example).

Regenerate

Cycle strategies aim to cycle and reuse materials at their highest value: they maximise the volume of secondary materials re-entering the economy, ultimately minimising the need for virgin material inputs and therefore also narrowing flows. Of course, virgin materials will always be needed to a degree: all materials degrade and can’t be cycled infinitely, use energy, and require blending with virgin materials to maintain strength and functionality.

A framework of policy instruments that enable and stimulate the transition to the circular economy

The principles of a circular economy concern designing out waste, regenerating ecosystems and keeping items in use. Decoupling the economy from material flows—improving the rate of resource productivity faster than the economic growth rate—is also a consistent guide. By evolving with the growing number of applications of circular economy principles, and consolidating these strategies across thematic areas, Circle Economy’s Key Elements Framework (KE) renders the elements of the circular economy salient and serves as a basis to derive contextual strategies and interventions. 


The Framework consists of:
- Core Elements: Activities directly handling product or material flows; and uniquely,
- Enabling Elements: those that remove obstacles for core actors.

Circle Economy's framework of strategies and activities that define the circular economy

The Circular City Actions Framework provides urban changemakers with five complementary strategies they can use to start working towards a more circular system. 

The framework is action-based to provide users with concrete strategic directions and showcase the desired outcomes of each strategy. 
The framework consists of five complementary **strategies**, under which **sub-strategies** provide further detail. Finally, each sub-strategy consists of a diversity of tangible **solutions** which are framed in relation to key thematic areas. 

Note: solutions are currently focused on:
- 🍏 **Food systems**
- 🏢  **Built environment**
- 👕📱  **Consumer goods**
- ⚡ **Energy Systems**
- 🚌 **Mobility Systems**
- 💧 **Water Systems**

More thematic areas are coming soon...

Based on the work of [Bocken et al. (2016)](https://www.researchgate.net/publication/309699661_Product_design_and_business_model_strategies_for_a_circular_economy), the Four Flows Framework serves as a simple framework for managing resource flows in a circular economy by using less (Narrow), using for longer (Slow), using again (Cycle), and using clean, regenerative materials and energy (Regenerate).

These different principles of circular economy can be applied to our socioeconomic metabolism: we can design stocks like buildings, infrastructure, machinery, and vehicles to be rich resource mines for the future, and design manufactured goods and consumables to be cycled and made regenerative. Furthermore, the focus must also centre on getting more value out of fewer materials. Achieving the aims of a circular economy—minimising material use, regenerating the Earth, and preventing material losses—can be done through these four key strategies mentioned above.

65% of Quezon City’s electric consumption is for streetlights.
The city government adopted a plan to increase energy efficiency, under a World Bank-sponsored programme.
Growing 2,8-million Quezon City updated its Land Use Plan to balance urban development with the preservation of its green spaces.

The night sky in Quezon City is dotted by blue, orange and white lights that surround the bay of Manila. These streetlights will now be more efficient and consume less energy.
A dynamic and growing city, belonging among other cities to Metro Manila, the national capital of the Philippines, Quezon City is the most populated city in the country. Having been the national capital for almost three decades, Quezon City is also the site of many government offices, including the Batasang Pambansa Complex, which is the seat of the House of Representatives.
The city is one of the beneficiaries of World Bank’s three-year Carbon Financing Capacity Building Programme (CFCB) in Emerging Cities of the South and in ECOS (Ecology, Economy and Social Responsibility). The aim of the programme is to assist cities in industrialized and developing countries to mitigate greenhouse gas emissions and to adapt to the effects of climate change.
As part of a comprehensive attempt to drive sustainable urban development, the local government has chosen as its CFCB project “Energy Efficiency from Streetlighting”. Streetlights constitute almost 65% of the city’s annual electric consumption with an average monthly billing of $615,000. The administration plans to establish baseline data on energy efficiency and emission reduction from the use of LED technologies, reducing electric consumption (which means less costs and less CO2 emissions).
Quezon’s administration acknowledges that balancing urban development with the preservation of green spaces and improvement of quality of life is a crucial challenge for a 2.8-million-people city. With this idea in mind, the city government updated its Comprehensive Land Use Plan, adopting the modern trend towards balanced, mixed-use communities and recognizing the need to maintain environmentally protected zones especially around the city’s reservoir. Local ordinances were also passed, prescribing standards for the design, construction and retrofitting of buildings in the city, and requiring all new buildings and housing construction in Quezon City to devote at least 30% of their roof area to plants and trees. It also launched an improved waste management and reduction plan, aiming at cutting in half solid waste, the only major city in the Philippines to adopt this measure. Part of the waste is now helping produce clean energy, thanks to the biogas plant located in Payatas. The Biogas Emissions Reduction Project was also registered with the United Nations Framework Convention on Climate Change (UNFCCC) as the country’s first Clean Development Mechanism (CDM). With revenues from carbon credits, the city government is funding socio-economic and livelihood programs for the Payatas community.
Due to its exposure to tropical cyclones and flooding, Quezon City and Metro Manila as a whole are threatened by climate change. Typhoon Glenda, in 2014, was the last to wreak havoc, causing death and destruction. Floods are becoming a familiar sight in this area, which prompted the local authority to earmark $3,4 million for flood control. The 21 projects include improvement of drainage systems, construction of ripraps, retaining walls and box culverts.

“The recent string of typhoons and storms has caused the death of many of our citizens, mostly living along the banks of our rivers” said Herbert Bautista, mayor of Quezon City and chairperson of ICLEI South-East Asia. “The best part of our efforts is now focused on protecting our citizens by being prepared to adverse weather conditions driven by climate change and doing our part to ensure climate change is kept under control”

Homes and businesses, natural resources and landscapes, in Quezon City as elsewhere, will be at risk if no agreement is reached between developed and developing countries on how to tackle climate change and who should bear the costs of reducing emissions and mitigating increasing climate instability.
Quezon City is an ICLEI Member and is reporting its carbon emission reduction targets and progress on the carbonn Climate Registry.

Rampant material extraction is pushing the ecosystems of Latin America and the Caribbean (LAC) to their limits. Over 11% of global raw materials are extracted within the region, yet it represents only about 8% of the world's population.

[*The Circularity Gap Report* (CGR) Latin America and the Caribbean](https://www.circularity-gap.world/lac), a first of its kind, demonstrates how the region can leverage the circular economy to tackle systemic inefficiencies in satisfying societal needs, conserve its unique natural wealth, and improve its people’s well-being.

To devise pathways for a circular transition, the report analysed the sectors where circular interventions could yield the most positive impact—environmentally, economically, and socially. This entails shifting to a circular food system, building a circular built environment, advancing circular manufacturing, transforming the energy system, reducing waste generation, and improve waste cycling.

[Circle Economy](https://www.circle-economy.com/) is a global impact organisation with an international team of passionate experts based in Amsterdam. We empower industries, cities, and nations with practical and scalable solutions to put the circular economy into action. Our vision is an economic system that ensures the planet and all people can thrive. To avoid climate breakdown, our goal is to double global circularity by 2032. Through the Circularity Gap Reporting Initiative, our mission is to deliver Circularity Metrics that measure the state of the global and national economy and identify key levers to transition to circularity.

The circular potential of organic wastes is dependent on the quality and low contamination rate of the residual stream that is collected. Food and organic wastes are difficult to sort and separate post-collection, and as such, collecting organic wastes through a mixed collection are often limited to incineration or landfill. Therefore, collecting organic wastes through a separate collection system is key to unlock potential high-value management practices, for example, composting and anaerobic digestion.

Due to the strong influence over the operation of local waste management systems, local governments have a key role in the provision of separate organic waste collection systems throughout the city. Collections systems can vary to suit the specific characteristics of particular neighbourhoods and areas of a city. For example, areas with detached homes have more space for bins, while for apartments with less space, a communal receptacle may be more appropriate. Communication campaigns can help to raise awareness and encourage participation of residents to separate their organic wastes.

🍏  Separate organic waste collection infrastructure

The food system nourishes populations and employs 50% of the global workforce, but:
- it currently drives a quarter of the overshoot on the climate change planetary boundary due to its greenhouse gas (GHG) production, 
- animal farming alone uses over one-quarter of all land, equivalent to the size of the Americas,
- nearly a quarter of freshwater resources are lost due to rampant food waste, and
- it is the single largest driver of biodiversity loss.

A circular food system must address the whole value chain, from production to consumption to waste management. The four key solutions for the food system are:
- Put healthier, satiating foods first: Prioritise satiating and healthy foods with a lower environmental impact—ideally shifting calories from meat, fish, and dairy towards cereals, fruits, vegetables, and nuts.
- Go local, seasonal, and organic: Prioritise the production and consumption of local, seasonal, and organic produce (sometimes in combination with GMO to reduce pests and disease loss on crops), which can lead to a significantly reduced need for chemical inputs, fuels, and processing services that contribute to environmental impacts.
- Mainstream regenerative agriculture: Scale up agricultural practices that regenerate ecosystems, recirculate nutrients and sequester carbon by design. 
- End avoidable food waste: Minimise food loss and valorise waste following the food waste hierarchy along the supply chain and at the consumer level through better management of transport and storage, more refrigeration and smart planning, and technology at the consumer and food service levels.



🍏 Food Systems

Cities consume about 75% of global energy and emit between 50% and 60% of global greenhouse gases (UN-Habitat). To reduce the negative impact of their energy consumption, cities need to shift away from fossil fuels and move towards renewable energy sources. Such a shift will help cities work towards their climate change mitigation and adaptation action plans. Renewable energy technologies such as wind, water, solar, and geothermal can also help improve access to energy in vulnerable and marginalised neighbourhoods through, for example, decentralised, off-grid solutions.

Renewable energy technologies can harvest the energy in nature’s processes, such as wind, and solar radiation and geothermal heat, that can be replenished within a human lifespan. In contrast, fossil fuels are materials that are not replenished within a human lifespan and are combusted for energy, losing the fuel material and resulting in emissions.

Local governments can develop sustainable energy plans, considering different energy resources and requirements, to develop a robust strategy for the development of renewable energy technologies and infrastructure throughout the city. They can also institute specific legislation and tax systems to regulate energy production and consumption, incentivise research and development of cleaner, more efficient technologies. Via Power Purchase Agreements cities can buy renewable energy from green energy providers and fix the price in order to provide security to financial institutions to finance renewable energy infrastructure. Furthermore, increasing awareness and facilitating capacity-building on planning urban sustainable energy projects can help the uptake of clean energy across the city by different stakeholders—from citizens to businesses and institutions. Facilitating collaboration, then, will be crucial, since private companies operate most of the world’s energy systems.


⚡ Energy Systems

When organic wastes are landfilled, the value and nutrients are lost and irrecoverable. Landfilling also causes additional environmental pressure, for example, the decomposition of food and organic waste in landfills emits greenhouse gases into the climate. Reducing the space required for landfills creates opportunities for better use. 

Local governments have an important role to play in the elimination of the landfilling of organic wastes. Municipalities with the legislative authority to do so can introduce legislation that bans organic wastes from being landfilled and fines non-compliance.

Municipalities can ensure that municipal organic wastes are collected and diverted from landfill by mandating certain processing techniques, for example, composting or anaerobic digestion.

🍏  Phase out landfilling of organic waste

Thematic Areas

                 This document has been realized as part of the second phase of the City Assistance Project offered to the Municipality of Sao Paulo (Brazil) under the framework of the Climate and Clean Air Coalition Municipal Solid Waste Initiative (CCAC MSWI). The project was implemented by ISWA, the International Solid Waste Association, with the local coordination of ABRELPE, the Brazilian Association of Public Cleaning and Special Waste Companies (ISWA’s National Member in Brazil). The first phase of the project was a city assessment and the establishment of an Action Plan for Sao Paulo, in line with Sao Paulo’s PGIRS (Plan for Integrated Management of Solid Waste) lasting from 2014 to 2033. The second phase of the project aims to provide technical and strategic guidance on how to pursue the Action Plan and build capacity in public communication and organic waste treatment plant operation. This strategy paper is an outcome of one of the activities in the second phase, namely for the Action “Define the strategy for organic waste diversion and help realize a pilot biowaste treatment plant” of the Action Plan. The idea of this activity came about after assessing the current Municipal Solid Waste (MSW) management activities in Sao Paulo and considering the targets and guidelines defined in Sao Paulo’s Master Plan for the City of Sao Paulo (Plano de Gestão Integrada de Resíduos Sólidos da Cidade de Sao Paulo - PGIRS). The Master Plan strongly emphasizes the role of diverting organic waste from disposal (currently into landfills) by means of reducing it at source (e.g. home-composting), separate collection at large producers and households and recycling by applying composting, anaerobic digestion and pretreatment with MBT (mechanic-biological treatment) technologies. Specifically, the PGIRS foresees the realization of composting/AD/MBT plants for a total treatment capacity of about 4.700 tons/day or 1,7 million tons/year. Sao Paulo needs strategic guidance on how to achieve those goals, so the aims of the strategic guidance are to develop:  A strategy for organic waste diversion including collection, treatment and recycling and their challenges and opportunities for Sao Paulo, namely this document; A technical guidance on the operation of organic waste treatment plants taking into consideration the existing legal framework. This deliverable constitutes another document.
 Data quoted in this paper are from the PDF version of the PGIRS and the Executive Summary of it (hard-copy) dated 2014. Existing Brazilian legislations and technical norms are described according to the existing status as at the end of January 2016.

Managing municipal food wastes at scale may require complex and costly infrastructures to collect, transport and process these residual materials. Large-scale composting facilities are challenging to place and zone appropriately in space-scarce cities.

Community-based initiatives, for example, community composting, can provide a localised solution to managing urban food wastes. Community composting initiatives are small(er)-scale solutions that are distributed throughout the city, located close to the sources of food waste, reducing the need for complex logistics and collection systems. Community composting schemes can take a variety of forms, for example, in-vessel composting (IVC), as well as vermicomposting (which utilises insects to break down organic materials). Community composting initiatives can generate valuable by-products for use in (urban) agriculture, in gardens and in parks, as well as support community building. 

Local governments can support the development and implementation of community composting schemes through the provision of equipment and infrastructure, for example,  composting boxes. The formation of public-civic partnerships can help formulate the relationships and validate the valuable role such activities can play in the management of organic waste streams. Awareness raising can be facilitated through collaboration with schools.

                   trasmettiamo conoscenza in modo appassionato e in sintonia con le esigenze ed i programmi formativi della scuola         I nostri progetti non sono “calati” dall’alto ma vengono formulati in collaborazione ed in sinergia con gli Insegnanti coinvolti, privilegiando l’interazione con le attività didattiche ordinarie.  In questo modo definiamo con precisione gli argomenti da sviluppare, lasciando ampio margine di gestione in proprio degli argomenti di progetto al corpo docente.
Le nostre proposte includono sempre un’attività di aggiornamento e di formazione degli insegnati, per arricchire le conoscenze dei docenti e dare loro le competenze ed i materiali per sviluppare anche autonomamente percorsi didattici su diverse tematiche. Le nostre proposte focalizzano su tre tematiche principali:                          Lavorariamo trasversalmente con le diverse classi ed età degli alunni, cercando di limitare gli interventi dei ns. esperti in classe per lasciare ampio spazio al ruole dei docenti ordinari.
I nostri progetti prevedono sia momenti di aula (didattica convenzionale) che attività esperenziali (gioco, bricolage) e attività sul territorio in cui è inserita la scuola.                                                                    Gli obbiettivi e le finalità del progetto realizzato nell’A.S. 2016/2017 sono:

comprendere il problema dei rifiuti;
rendere i bambini consapevoli dell’importanza del rispetto del proprio quartiere, una terra condivisa;
creare un contesto autentico e motivante a scuola;
creare un processo di interazione/condivisione anche con le famiglie;
lavorare a scuola in modo interdisciplinare, aumentando la collaborazione tra gli insegnanti

Altereko ha curato la stesura del progetto didattico con le insegnanti, realizzato un seminario di orientamento e formazione iniziale e svolto diversi interventi mirati con e nelle classi.

      A handbook for schools on waste management focused on the organic fraction which aims to:  Emphasize the important role that schools play as a waste generator as well as an educational agent sensitizing the future generations on solid waste management; demonstrate the potential for reduction of waste and GHG emissions from schools through source separation, reuse, and recycling of organic waste. Empower teachers and school directors by providing technical knowledge on waste and particularly on organic waste management: characteristics, treatment techniques, challenges, and benefits; Present cases of schools in Sao Paulo that have been successful in managing  the organic fraction of their waste; Encourage schools that do not yet take actions to start activities regarding managing waste particularly the organic fraction; Spread waste management education wide across schools in Sao Paulo and eventually in others countries by providing a handbook in a comprehensive approach
 The target audience of the Handbook is teachers who intend to introduce the topic of recycling organics by means of composting in schools, but also to improve the separation of quality dry recyclables. It provides a general overview about the opportunities and possibilities to teach about composting, practical information about how to sort organic waste in schools and how to manage the composting process with children between 3 and 14 years old. The Handbook is also available in Portuguese.   

      By properly disposing of organic waste, São Paulo’s 1,500 municipal schools can prevent emissions equivalent to 40,000 tons of carbon dioxide annually.            

 
           The City of São Paulo has launched a manual designed to encourage schools to separate and recycle organic waste with the aim of reducing both food waste and emissions of greenhouse gases, like methane, from decomposing organic waste. The Handbook for Schools on Organic Waste Management aims to empower teachers and school directors by providing technical knowledge on organic waste management, including: characteristics, treatment techniques, challenges and benefits. It emphasizes the important role schools play in waste generation and in influencing future generations to manage waste properly.   The potential for schools to reduce waste and greenhouse gas emissions by source separation, reuse, and recycling of organic waste is high. São Paulo’s 1,500 municipal schools serve 245 million meals, generating 30,000 tons of food waste, every year. Green waste from gardening and grounds maintenance adds another 15,000 tons of organic waste annually. If the 45,000 tons of organic waste are composted locally the city can prevent the equivalent of approximately 40,000 tons of carbon dioxide emissions from entering the atmosphere. At the launch Bruno Covas, Vice Mayor of São Paulo, said the project provided multiple benefits for the city including the building of important partnerships, reduction of greenhouse gas emissions, better treatment of solid waste, and the creation of more conscious citizens. Mr Covas hopes that the schools initiative will encourage more schools, in São Paulo, across Brazil, and internationally, to properly manage waste. “Global warming is an issue that demands the most attention and care, and the contribution of environmental education in schools is important to prepare the next generation of citizens,” Mr Covas, said. “In schools we not only form new citizens, but create the opportunity for them to take home what they’ve learned and teach others how we can live in society, and think about the natural resources that we have to leave for our children and grandchildren."            

 
 The Vice Mayor of São Paulo, Mr. Bruno Covas, speaking at the launch 
  
   São Paulo’s Municipal Education Secretary, Alexandre Schneider congratulated the schools taking part saying the experience of helping to develop the materials contributed to making the world a better place. "We want to bring this experience to the more than 1,500 municipal schools here in São Paulo,” Mr Schneider said. “It is our role to bring the whole process of vigorous environmental education to work on issues related to the environment and sustainability. We want children to be able to learn English, math, Portuguese, but we also want to form citizens with these values ​​we have in our network, which we need to preserve and carry forward." The publication also features exemplary cases of organic waste management, such as that of EMEI Dona Leopoldina, in Lapa, which has 230 students and generates about 300 kg of organic waste, which is treated and processed into compost to fertilize the local vegetable garden. Mr Gilberto Natalini, São Paulo’s Secretary of Environment said the handbook will be distributed throughout the city and should have a significant result.

   “Solid waste is one of the many environmental and urban challenges of a city, and organic waste is a priority issue that needs to be addressed because it accounts for half the current volume generated and sent to landfills,” Mr Natalini said. “It is our dream, and I am sure that with the help of all, we will move forward and prevent all this material from going to landfills.” The handbook was developed by the International Solid Waste Association (ISWA), a non-governmental and non-profit organization for the Climate and Clean Air Coalition (CCAC), whose Municipal Solid Waste Initiative works with cities around the world to reduce emissions of short-lived climate pollutants like methane and black carbon from waste.  Its production is part of the CCAC’s technical assistance to the city, which is implemented by ISWA with local coordination by the Brazilian Association of Public Cleaning and Special Waste Companies (Associação Brasileira das Empresas de Limpeza Pública e Resíduos Especiais or ABRELPE).

   Mr Carlos Silva Filho, President of ABRELPE, and Vice President of ISWA, said the project has been very interesting and ambitious for a city the size of São Paulo. “The school handbook demonstrates the potential local initiatives can have on climate change by improving organic waste management and composting. The 1,500 municipal schools of São Paulo have the potential to contribute 4% of São Paulo State's 2020 emission reduction target,” Mr Silva Filho said.  “We are very proud of what we have achieved so far and to provide further assistance to São Paulo as part of the CCAC.” The Handbook for Schools on Organic Waste Management was launched on 18th of April 2017 at the Municipal Secretariat of Education, in São Paulo, Brazil, with participation of around 50 representatives from schools and municipal staff.

São Paulo, Brazil, realised a handbook on composting in schools to support local teachers who intend to teach composting practices. Home composting is encouraged by the government of São Paulo as part of the Integrated Solid Waste Management Plan, which delivered compost bins to houses.&nbsp;
