Curitiba – Greca highlights circular economy strategies in his opening address to the Argentine authorities

In Buenos Aires, this Tuesday morning (18/10), the mayor of Curitiba, Rafael Greca, highlighted the strategies of the capital city of Parana in promoting a circular economy for sustainable development.

The mayor of Curitiba is in the Argentine capital this week to participate in the C40 World Summit of Mayors, an international forum of governments representing the Group of Major Cities for Climate Leadership.

“Curitiba is moving towards the transition to a circular economy with a collaborative approach, in partnership with different production sectors. Innovations, the use of technology and other initiatives led by institutions, industries, companies and commerce, such as the Buenos Aires Stock Exchange, are essential for the construction and success of the circular economy”, said Greca, speaking after the host city’s mayor, Horácio Larreta.

Opening the ceremony, the president of the Buenos Aires Stock Exchange, Adelmo Gabbi, cited Curitiba as an example of a city. The mayor of Buenos Aires, Horácio Larreta, spoke about the expansion of the BRT axis in the capital of Argentina and mentioned Curitiba as a symbol of sustainable transport.

“Innovation exists only if it is transformed into a social process. Balanced and orderly development of cities begins with planning focused on urban and human sustainability. Overcoming the bureaucracy and turning the planned into practice is the mayor’s task and challenge for a better life,” said the mayor of Curitiba.

sustainable practices

In his presentation, Greca highlighted Curitiba’s history in sustainable projects and practices that position the capital of Paraná as the Brazilian capital that recycles the most waste (20% of total waste produced), as part of the Lixo que Não é Lixo (Lixo que Não é Lixo) program.

Caximba and PlanClima

Greca highlighted the Bairro Novo Caximba climate risk management project as a pilot for the wide implementation of circular economy concepts, with the aim of social emancipation of the population involved in the project and ecological recovery of the implementation area.

He also pointed out that the development of circular economy strategies is already one of the activities of PlanClima, Curitiba’s climate action plan. In addition, as part of the partnership with the Ellen MacArthur Foundation, technical-institutional training is underway in the capital city of Parana for the development of a circular economy municipal plan/program that should be included in the guidelines of the Sector Plan for Economic Development, one of the tools of the Curitiba Master Plan.

As part of the C40 commitments, Curitiba also adheres to Zero Waste, which envisages the development of a strategy, over the next two years, to expand the processing of organic waste and reduce discarded waste. By 2030, it is intended to reduce the amount of organic waste by up to 30% and also by 30% the emissions caused by waste disposal in general.

circular economy

The circular economy is a model of systemic solutions based on three design-driven principles: elimination of waste and pollution, circulation of products and materials at their highest value, and regeneration of nature. In a circular economy, business models, products and materials are designed to maximize their use and reuse, creating an economy where there is no waste and everything has value. Based on the transition to renewable energy sources and renewable materials, the circular economy is distributed, diverse and inclusive.
