Circular City
Cities have tremendous power to drive change toward more circular, closed-loop systems.
Some of the ways cities can improve their efficiency and quality of life are to:
Electric-powered
vehicles
Circular building
kit
Renewable
energy
Water
conservation

Electric-powered vehicles
Reduce the need for vehicles (and shift to electric-powered ones) by improving public transportation and bicycle infrastructure within cities.
Redesign the way we construct building to make more efficient use of resources and energy. A circular economy could reduce global CO2 emissions from buildings materials by 38% in 2050.¹⁸ The Circular Building Toolkit recommends a number of strategies, including build nothing, build long-term value, build efficiently and build with the right materials.¹⁹
Circular building kit
Use renewable energy, including bioenergy that can be recycled from food and other organic waste in Amsterdam found that using biorefineries, waste separation and return logistics could lead to added value of 150 million, as well as 900,000 tons of material savings and a reduction of 600,000 tons in CO2 emissions annually for the city.²⁰
Renewable energy
Improve water conservation and treatment systems to conserve water within city limits. Recovering energy in the wastewater sector can actually offset the energy required for treatment: A Hungarian-based company, Biopolus, has created a modular urban water treatment system to harness clean water, energy, nutrients and minerals from wastewater and organic waste.²¹
