Designing sustainable cities will require turning waste into raw materials.
Much of the world’s population is concentrated in cities, where huge amounts of waste are generated.
This waste becomes a pollutant if it ends up in the wrong place, such as our bodies, air or water.
If instead of considering waste as a nuisance, we managed it as a valuable resource, it could offer solutions to multiple problems and create a more sustainable future for billions of people.
An effective way to make a city sustainable is to reduce all waste streams and use them as resources. Waste from one process becomes the raw material for another.
Much of the world’s population continues to migrate to cities, putting urban centers at the forefront of solving the global resource problem. The climate agreements reached in 2015 in Paris also recognized the key role of cities.
Changing building codes and investing in energy efficiency are just two initial steps that, according to many leaders, could be implemented much faster by city councils than by national governments.
It makes sense for cities to step up. The population of some cities (New York, Mexico City, Beijing) exceeds that of entire countries, and the urban landscape emerges where many vital challenges are concentrated. Cities can lead change because they are able to provide solutions quickly and because they are living laboratories for improving the quality of life without depleting the planet’s resources, polluting the air and water, or damaging our health.
Cities abound in wasted energy, wasted CO2, wasted food, wasted water, wasted space and wasted time. Reducing each waste stream and managing it as a resource, rather than a cost, could solve multiple problems at once and create a more sustainable future for billions of people.
