Circular Economy in Cities Evolving the model for a sustainable urban future
The linear methods of production and consumption are unsustainable for the planet. As urbanization continues, the demand for greater resources will accelerate if the current consumption trajectory persists. For cities, this means increased waste. The linear model of “produce, use, dispose” is inherently wasteful, while the circular economy is conceptualized as a continuous cycle of value preservation and resource optimization, offering sustainable alternatives for eliminating waste.
Today, more than half of the world’s population lives in cities, a figure projected to rise to 70% by 2050. The quality and resource efficiency of cities will become an increasingly critical issue. Cities are engines of economic growth, generating approximately 85% of global GDP. They are places where people live, work, innovate, and consume significant amounts of resources. Therefore, cities play a pivotal role in the transition to a circular economy.
Making cities sustainable requires rethinking every element of urban living. This includes moving away from practices such as landfill dumping and the degradation of resources (e.g., waste incineration). It is imperative that solutions are implemented to ensure products are kept in circulation, minimizing the loss of resources during production and consumption processes.
This White Paper seeks to highlight innovative solutions that apply circular principles to upcycle waste from existing buildings, infrastructure, and construction; harvest rainwater for reuse; generate clean and resource-efficient energy; treat medicinal waste; and procure goods and services sustainably.
The transition to a circular economy can only be achieved when all stakeholders—individuals, the private sector, government, and civil society—collaborate. The Forum hopes that these recommendations will pave the way towards a more sustainable, livable, and healthier urban future, as well as spur additional circular initiatives in cities.
