Too often buildings end up as waste at the end of their lifecycle. How can the built environment move towards a circular economy, and in turn, reimagine how valuable materials are tracked and recycled? Looking to address this issue, material passports are one idea that involves rethinking how materials are recovered during renovation and demolition for reuse. The result is when a building is ready to be demolished, it becomes a storage bank for useful materials.
Schoonschip is Amsterdam’s innovative circular neighbourhood, a community-driven project set to become a prototype for floating urban developments. With a masterplan designed by Dutch architecture practice Space&Matter, the project comprises 46 dwellings across 30 water plots connected by a jetty and features decentralised and sustainable energy, water and waste systems. With the last of its buildings completed this year, the development showcases a valid adaptation strategy in the face of climate change and rising sea levels.

A circular economy is an economic system aimed at eliminating waste and the continual use of resources. Looking beyond the current take-make-waste extractive industrial model, a circular economy aims to redefine growth, focusing on positive society-wide benefits. It entails gradually decoupling economic activity from the consumption of finite resources and designing waste out of the system. Underpinned by a transition to renewable energy sources, the circular model builds economic, natural, and social capital.
It is based on three principles:
With the inauguration of the 17th Venice Architecture Biennale, 60 nations from across the world showcased unique solutions to the question of “How will we live together”. Neither the pandemic nor its repercussions got in the way of the curators' creative process. Instead, they took it as a factor to explore how the notion of 'living together' has changed over the past year, and how they can reimagine better built environments. ArchDaily had the opportunity to meet with architect Wael Al Awar, one of the co-curators of the UAE Pavilion, to discuss how the pavilion's innovative material came to be and what it means for the future of architecture.
The concept of “decarbonization” has been in vogue recently in political speeches and global environmental events, but it has not yet gained enough attention in the field of architecture to profoundly change the way we design and construct the world of tomorrow. Buildings are currently responsible for 33% of global energy consumption and 39% of greenhouse gas emissions, indicating that architects must play a significant role if we are to stop or reverse climate change. With carbon acting as a universally agreed upon metric with which the greenhouse gas emissions of a building can be tracked [1], one of the most important ways through which this goal can be achieved is therefore the decarbonization of buildings.
Making material recycling commonplace within the architectural field would require a top-down approach in adapting the industry’s processes and standards to create a suitable framework for the task. However, individual endeavours are bringing about change within the profession, pushing for a reconsideration of architecture’s relationship to waste. This article looks at some of the initiatives that are spearheading the transition towards a common practice of material recycling.
Some researchers define the Anthropocene as beginning at the Industrial Revolution. Others identify it with the explosion of the first nuclear bomb, and others with the advent of agriculture. Regarding the precise timeline, there is not yet a scientific consensus. But the notion that human activities have been generating changes with planetary repercussions, whether in the temperature of the Earth, in biomes, or in ecosystems, is one that has become increasingly popular. The anthropocene would be a new geological era marked by the impact of human action on planet Earth. This acknowledgement of human impact is particularly disturbing if we consider that if the entire history of the Earth were condensed in 24 hours, humans would only appear in the last 20 seconds. Whether in the massive extraction of natural resources or in the carbon release from vehicles and industries, it is well known that a large part of the fault lies with construction activities, especially in the production of solid waste due to waste and demolition. In Brazil, for example, civil construction waste can represent between 50% and 70% of the mass of solid urban waste [1]. Many will end up being discarded irregularly or thrown in landfills to be buried indefinitely.
The concept of Design for Disassembly (DfD for short) gained increasing traction in recent years, as it addresses the growing concern around the high consumption of resources and low recycling rate within the construction industry. The following article details on the method and features guidelines for a design process that facilitates the dismantlement of future buildings, with the scope of providing a better understanding of this principle within the broader framework of the current practice and circular economy.
White Arkitekter, in collaboration with Silicon Valley-based ReGen Villages, have joined forces to create fully circular, self-sufficient and resilient communities in Sweden. Inspired by computer games, the project puts in place organic food production, locally produced and stored energy, comprehensive recycling, and climate positive buildings.
SFERA 2020: BIOURBANISM is an international conference on building better cities using knowledge about the natural world around us.
Located in a prime location in the city of Taipei, the invaluable large open space at the Taiwan Contemporary Culture Lab (C-LAB) is historically significant as it used to be home to the Industrial Research Institute of the Taiwanese Governor-General’s Office and also the Air Force Command Headquarters under the Ministry of National Defense. Since the Ministry of Culture took over its operations in 2018, C-LAB has become a place for art and cultural experimentation, with various participatory events and actions initiated and reflections and imaginations for contemporary urban space and lifestyle projected.
German architecture and design practice HPP Architekten have created a proposal for a hybrid timber office building along the Düsseldorf riverfront. Inspired by the circular economy and the Cradle to Cradle concept, the design for the project aims to show how architecture can become part of more sustainable cities. Working with developer INTERBODEN, the team plans to show how individual components can be recycled after use, non-recyclable materials minimized and CO2 emissions reduced.
