Like many cities, Ljubljana is faced with significant overgrowth of Japanese knotweed, a plant on the list of 100 most invasive non-native species worldwide. Ljubljana teamed up with the Re-generacija collective of young designers and architects focused on issues connected to social and environmental well-being, as well as the University Botanic Gardens Ljubljana, the Pulp and Paper Institute and the public waste management company, Snaga, to prevent excessive overgrowth of the plant and reuse it.
Utrecht, one of the four biggest cities in the Netherlands, aims to be climate neutral in 2030 and to reach a fully circular economy by 2050. In the shorter term, Utrecht is committed to increasing its share of circular procurement from 4% of the annual spend in 2016 to 10% by 2020. Utrecht’s sustainable vision is also reflected in its aspiration to become the most bike-friendly city in the world.
Lyon Métropole, which includes 59 municipalities and 1.3 million inhabitants, wants to build a sustainable future for its citizens. The Métropole relies on green investments to face environmental challenges. Lyon is also committed to building circular solutions for the region and has been recognised as a ‘zero waste territory’ (territoire zéro déchet, zéro gaspillage) since 2015. In April 2017, Lyon Métropole voted on strategic actions in favour of the circular economy.
Oslo has been developing a waste management system based on circular principles to ensure separate waste collection is maximised and transform waste into secondary raw materials. To do so it has actively engaged with citizens, farmers as well as with its city’s public transportation company.
Facing dramatic deindustrialisation and an uncertain future, the city of Turin implemented processes that paired physical redevelopment with strategic planning to promote citywide revitalisation and economic restructuring in the 1990s. While the transformation has been profound, current challenges call for more circular strategies and an inclusive approach.
Munich has taken its ambitious waste reduction strategy to the next level by developing an innovative reuse lab and shop concept. Its Halle 2 municipal secondhand store not only enables citizens to take responsibility for living more sustainably, it also provides opportunities for job creation, educational programmes and voluntary activities.
As a densely populated and economically powerful urban area, the city of Dusseldorf recognised the challenge of climate change early on and initiated a process of low carbon and zero waste strategy development.
In 2015 Amsterdam commissioned an in-depth study on the potential of a circular economy. The project was the first large-scale research study in the world that uses the ‘city circle scan’ methodology. The scan identifies the areas in which the most significant, tangible progress in realising a circular economy can be achieved. This potential impact is significant and can result in more jobs, bring added value to the city’s economy, and reduce carbon dioxide emissions and material use.
Birmingham is Britain’s youngest and fastest growing city, boasting the highest quality of life of any English city outside London. The city also has the strongest economy outside the capital and is one of the first cities to adopt a proactive industrial symbiosis approach to develop a medium and long-term strategy for sustainable economic development. Often described as ‘the circular economy in action’, the projects born from the industrial symbiosis approach are part of Birmingham’s circular economy strategy.
The purpose of the project has been to highlight the possibilities the municipalities and regions have to accommodate a more circular economy in the future.
The Granada Sur Biorefinery of Emasagra has set up an ambitious environmental strategy in order to become European circular economy reference in the field of sanitation and wastewater treatment.
Cities and regions in Alpine Space have mainly set their low-carbon objectives and adopted relevant strategies in energy, mobility, construction aso. The project GREENCYCLE aims to introduce the system of circular economy as a holistic approach to support implementation of low-carbon strategies and provide additional 2-4 % greenhouse emission reduction to the partner cities.
The city of Almere, working together with local stakeholders and the company Millvision, has developed an innovative circular economy partnership. Mowed plants from the local lake instead of just being disposed of, are now being integrated by Millvision, a paper company, in to biomass blends used to produce sustainable paper. The aquatic plant is a local and renewable input to the production of the paper but it also "circular" as something that would be discarded as waste is re-valued as a raw material used in production.
In one of its terminals, Schiphol Airport runs the project "Light as a service" whereby it pays for the light produced, while its two partners Philips and Cofely remain the owners of the lamps and fittings.
Thanks to this innovative partnership, maintenance costs are reduced and recyclability and reusability of the lighting and framing guaranteed.
Household organic waste and small plants: door to door collection solves the composting dilemma for inhabitants in Milan
The door to door households organic waste collection plan was first introduced in November 2012 in one quarter of the city of Milan and then was extended to the whole city in June 2014. Collection frequency is twice a week.The aim of the separate collection of food waste is to divert this material from incineration and to send it to AD for production of biogas and good quality compost.
