Synopsis

Eva Gladek shares her vision on circular cities and the circular economy, particularly on the urban systems approach adopted by Metabolic.

Starting with the development of De Ceuvel - Amsterdam’s sustainable business park and ‘cleantech playground’ - Metabolic has driven numerous circular urban development projects across the Netherlands and worldwide. Based on recent work with the city of Rotterdam and the city of Charlotte in the United States, Ms Gladek shares strategies for transforming cities to a circular economy - and the integral next steps that cities need to take to realize the transition.


Lecture Report

“Imagine a circular city where you have all of your wastes that are getting collected and reprocessed into valuable materials… within the city itself. All the buildings are designed for disassembly and recovery so you’re putting less pressure on mining and hinterland needs.

 

You’ve dramatically reduced the need for shipping and created new, smaller logistic cycles which need a different kind of management. It’s the kind of environment that we should want to live in.”

 

With its numerous green and blue spaces, Singapore is well known as a city in a garden. But can its urban life and the economy be further improved by taking inspiration from natural systems?

 

This was the prospect raised by Eva Gladek, founder and CEO of Metabolic, a consultancy specialising in circular cities and sustainability. In her recent CLC lecture in September 2018, she made a case for how circular economy principles can make cities more efficient, sustainable and liveable.

 

Today, cities spend a huge amount of energy, time and money on extracting resources from the environment to make products that are eventually thrown away. A circular economy means preserving the material, technical and knowledge inputs within products and establishing pathways for maintenance, reuse and adaptation to other uses.

 

“The circular economy is about creating extended, infinite cycles of value, just like a natural system does,” said Gladek.

 

An example Metabolic has developed in Amsterdam is De Ceuvel, a formerly polluted industrial site. Gladek and her team transformed this 5,000 m2 site by salvaging houseboats to adapt into buildings, and including wastewater treatment, composting, bio-digestion, a struvite reactor and greenhouse facilities. Its success led the Dutch city to request scaling up strategies for larger neighbourhoods, such as Buiksloterham.

 

“One of the reasons (why) the circular economy is becoming so popular, especially in Europe, is that this represents a huge pathway for saving a lot of money,” explained Gladek. “That is because all of that value is not getting destroyed, but getting retained and cycled through the system.”

 

According to management consultancy McKinsey, adopting a circular economy approach would save Europe up to US$630 billion per year. In another example cited by Gladek, it was calculated that comprehensive plastics recycling system in the city of Charlotte in the United States could save it more than 900,000 barrels of oil annually, as well as create an industry with US$35 million in revenue and more than 1,300 jobs.

 

More than just saving the environment and money, Metabolic defines the circular economy via seven pillars. This includes maintaining materials at their highest value of use, basing energy on renewables, the proper maintenance of water sources, supporting biodiversity, preserving human culture and society, preserving human health and wellbeing, as well as using resources in ways that generate multiple forms of value.

 

In addition to circular economy principles, Gladek says a structured, strategic approach towards interventions can result in cascading positive impacts too. For instance, shifting from monoculture (singlecrop agriculture) towards symbiotic agriculture systems where different crops are grown such that their input and output support one another. Mushrooms grown on coffee grounds may produce carbon dioxide for plants, which also receive other nutrients from fish. Similarly, black soldier flies can consume municipal organic waste, with their larvae being turned into animal feed or protein pastes.

 

“It’s more than just thinking: how do we close and fix all the resource cycles, but (also) about how do we create new integrated, symbiotic solutions,” said Gladek.

 

For highly developed cities like Singapore, she suggested turning towards more sustainable, resilient methods of construction. Buildings can be designed to be easily deconstructed and reused so as to close the cycle on building materials, reduce the pressure on landfills and create a lot more value. For instance, the Dutch have come up with this idea of “material passports” where they see their buildings as a “resource bank”, and track the different materials in them in digital databases. Such practices can enable the growth of new industries that extract scarce materials through up-cycling used products. In this way, countries can become resource brokers even though they have no access to natural resources.

 

With the emergence of climate change and its many impacts on our world today, there is a pressing case for cities to adopt a circular economy to tackle the root cause of over-consumption.

 

“There’s no reason why anyone should… say well, no, we actually want to be living in polluted, messy and wasteful environments,” said Gladek. “I think it’s just about making this vision really clear and building these business cases step by step, so we can all collectively move there.”
