A new, fully online Profed course on Circular Economy at an advanced level will be available by TU Delft, October 7. Come join us at the “Circular Building Products for a Sustainable Built Environment” online course, register now and enhance your learning on Circular Economy.
The course is suitable for architects, product designers, managers, supply chain actors and other professionals working towards the development of future products used to create sustainable, circular buildings. TU Delft’s Circular Built Environment hub (CBE) has designed and developed this course working with leading industry and research partners, to achieve a higher level of applicability and relevance. It is based on real world case studies and provides you with the tools to create new products and business models. It will help you to fully understand the complexity of the task and to be able to evaluate existing circular approaches. You won’t be alone: a group of highly qualified people will support your learning throughout the course. For more information please visit our page.
I have just read Jeremy Till’s Design after Design lecture and it is so inspiring.
Till discusses the ‘modern project’ using the principles of progress (“If the modern project is underpinned by the need to maintain progress on all fronts, then design is used as a messenger for that urge“), growth (“the modern project is only deemed credibly progressive on the back of markers of growth“), order (“The modern project was, and still is, a project of ordering and categorising, and with it a project of excluding and privileging“) and reason (“the application of rational thought to a given context in order to better it“) and how they are currently challenged by climate change. The modern project, he claims, does not respond to ethics. It will only address its own demise. Climate emergency also defies reason and the scientific method.
So, what about design then? “What we see,” says Till, “is a radical shift from design being attached and addicted to the production of the new, and into practices that pay attention to what comes before the object and what comes after it.” Design now “accommodates difference,” it is “a collective enterprise of sense-making,” it is “sensitive to systems of production, both material and human.”
After a very successful second re-run, our MOOC has been launched again last Monday! This is a self-paced MOOC, so you can start any time and also follow it in your own time. If you are a student, a working professional in the field of architecture, urban design and engineering and you want to know more about the circular economy, join the course and the instructors from our department will guide you through.
About this course
Building construction is one of the most waste producing sectors. In the European Union, construction alone accounts for approximately 30% of the raw material input. In addition, the different life-cycle stages of buildings, from construction to end-of-life, cause a significant environmental impact related to energy consumption, waste generation and direct and indirect greenhouse gas emissions.
The Circular Economy model offers guidelines and principles for promoting more sustainable building construction and reducing the impact on our environment. If you are interested in taking your first steps in transitioning to a more sustainable manner of construction, then this course is for you!
In this course you will become familiar with circularity as a systemic, multi-disciplinary approach, concerned with the different scale, from material to product, building, city, and region.
Some aspects of circularity that will be included in this course are maximizing reuse and recycle levels by closing the material loops. You will also learn how the Circular Economy can help to realign business incentives in supply chains, and how consumers can be engaged and contribute to the transition through new business models enabling circular design, reuse, repair, remanufacturing and recycling of building components.
In addition, you will learn how architecture and urban design can be adapted according to the principles of the Circular Economy and ensure that construction is more sustainable. You will also learn from case studies how companies already profitably incorporate this new theory into the design, construction and operation of the built environment.
What you’ll learn
At the end of the course you will be able to:
Recognize the principles of circularity and their application to the built environment
Identify the scales of the built environment from materials and products to cities and regions
Identify the life-cycle phases of building products and how they can be circular
Discuss design principles in building of products and key aspects such as stakeholders, incentives, time-frames, business models
Discuss the circular design and development approach for buildings and recognize the impact of a building on society and the environment during its life-cycle
Recognize the flows at different city scales and how they differ depending on the actors and the local context
Reflect on the complexity and variety of possible circular solutions in terms of energy, water and waste management
Analyze and map the different stages and value webs of building materials at the regional level
Reflect on possible environmental impacts of the different building life-cycle stages and activities along the value web
Explore the potential of intervening to steer the value web towards more circularity

Patrick Schroder, Promoting a Just Transition to an Inclusive CE, Clatham House (Report): The ‘just’ transition concept is not new; it comes from climate change and climate justice movements (…) many social and political issues have been neglected in planning for the CE transition (…) a just transition framework for the CE can identify opportunities that reduce waste and stimulate product innovation (…) low- and middle-income countries that rely heavily on ‘linear’ sectors and the export of these commodities to higher-income countries are likely to be negatively affected by the shift to circularity (…) there is a need for new international cooperation programmes and a global mechanism to mobilise dedicated support funds for countries in need (…) COVID19 has shown that global emergencies have fast forwarded processes that otherwise may take years (…) three points: a. CE is necessary for both long-term resource security and short-term supplies of important materials, b. there is a need to improve the working conditions of the informal CE (waste pickers etc) and c. global supply chains will be radically changed (…)
Cindy Isenhour, Department of Anthropology, Climate Change Institute, University of Maine | CRITIQUE I: CE cannot be just about efficiency and technological improvement alone within the confines of a global economic system (…) in fact, success of CE has been hindered in part by carbon leakage to developing countries, off-shorial waste or by other means of shifting environmental burdens and market externalities (…) for some critics, high levels of total material throughput emissions and consumption have cannibalised a great deal of the gains (…) evidence that CE has helped us to decouple growth from environmental degradation is sadly hard to come by still (…) critics claim that despite CE success is not solely dependent on regenerative design (new packaging materials, industrial symbiosis, nutrient cycling technologies or recyclable polymers), but it is also about a fundamental shift, in global societal organisation and cultural frameworks (…) these have the power to renegotiate the meaning of ownership-property-economic value on materials and how we measure the successor our economic system (…) Can CE be capable of cultural change?| CRITIQUE II: CE scholarship is focused on rational choice theory and ecological modernisation and based on cost-benefit analyses (…) however, economic decision-making is highly contextual and social (…) consumers don’t want to alienate themselves from their peer groups and their neighbours (…) there is a necessity of coordinated approaches and collective action between social actors, so as to build trust and possibility of collaboration (…) How do we implement a CE that recognises the sociality of the economy? | CRITIQUE III: CE represents a new commodity frontier (…) sustainability programming can often capture the resources for those segments of society that are already more fortunate leading to economic exclusion (…) How can we broaden participation in CE as well as its conceptualisation and operationalisation to ensure equity and justice?
(…) one could argue that culture is integrally tied into the notion of environmental sustainability (UNESCO 2009) given that human beings (and the societies within which they exist) have a relationship with the natural environment that transcends biophysical definitions (…) Chan et al. (2012b) argue that to value cultures entirely in economic terms “cannot reflect the full extent of their differences from other ecosystem services” and risks the unintended interpretation that different cultures can be bought or sold (…) There are a few examples of tools specifically designed to assess only cultural values (…) However, Alonso and Medici (2012) emphasise that the lack of assessment tools that specifically include cultural aspects alongside environmental, economic and social aspects directly contributes to the marginalisation of culture, particularly regarding development policies (…) “values are the building blocks of culture” (…) the notion of ‘value’ is arguably just as ambiguous as ‘culture’ (…) The role of values in the process of undertaking LCA studies has been recognised in relation to defining the problem, goal and scope; the selection of impact category indicators; the optional weighting element at impact assessment; and interpretation of results (…) values have an important—if largely unrecognised—role to play in influencing these choices about the inclusion of different processes on the basis that they are judged as more or less relevant to the decision situation (…) Accounting for differences in cultural perspectives will, in theory, help to “establish the seriousness” of environmental impacts (…) “broadening LCA towards social, cultural and economic aspects would move LCA from environmental towards sustainability assessments” (…) future research should focus on opportunities for the development of (a) a culturally inclusive LCSA process and (b) additional cultural indicators and/or dimensions of existing LCSA indicators that represent cultural values (…) Presenting decision makers with information about economic, social, environmental and cultural aspects will allow them to simultaneously consider a range of impacts associated with a given process

The Amsterdam City Doughnut is intended as a stimulus for cross-departmental collaboration within the City, and for connecting a wide network of city actors in an iterative process of change, as set out in the eight ‘M’s: mirror/ mission/ mobilize/ map/ mindset/ momentum/ monitor/ mmm!
The Doughnut’s ecological ceiling comprises nine planetary boundaries: ozone layer depletion/ climate change/ ocean acidification/ chemical pollution/ nitrogen & phosphorus loading/ freshwater withdrawals/ land conversion/ biodiversity loss/ air pollution in order to identify Earth’s critical life-supporting systems and the global limits of pressure that they can endure.
The inner ring of her donut sets out the minimum we need to lead a good life, derived from the UN’s sustainable development goals and agreed by world leaders of every political stripe. It ranges from food and clean water to a certain level of housing, sanitation, energy, education, healthcare, gender equality, income and political voice. Anyone not attaining such minimum standards is living in the doughnut’s hole. The outer ring of the doughnut, where the sprinkles go, represents the ecological ceiling drawn up by earth-system scientists. It highlights the boundaries across which human kind should not go to avoid damaging the climate, soils, oceans, the ozone layer, freshwater and abundant biodiversity.
Between the social foundation and the ecological ceiling lies a doughnut-shaped space in which it is possible to meet the needs of all people within the means of the living planet – an ecologically safe and socially just space in which humanity can thrive (…) The Doughnut’s social foundation, which is derived from the social priorities in the UN Sustainable Development Goals, sets out the minimum standard of living to which every human being has a claim. No one should be left in the hole in the middle of the Doughnut, falling short on the essentials of life, ranging from food and water to gender equality and having political voice.
The scheme was based on the concept of doughnut economics as explained in 2017 Kate Raworth’s book: “Doughnut Economics: Seven Ways to Think Like a 21st-Century Economist.” Raworth, who is part of the team responsible for this initiative commented: “Who would expect in a portrait of the city of Amsterdam that you would include labour rights in west Africa? And that is the value of the tool.”

Life Cycle Assessment (LCA) can assist in: ⎯ identifying opportunities to improve the environmental performance of products at various points in their life cycle ⎯ informing decision-makers in industry, government or non-government organizations (e.g. for the purpose of strategic planning, priority setting, product or process design or redesign), ⎯ the selection of relevant indicators of environmental performance, including measurement techniques, and ⎯ marketing (e.g. implementing an eco-labelling scheme, making an environmental claim, or producing an environmental product declaration).
There are four phases in an LCA study: a) the goal and scope definition phase: The scope, including the system boundary and level of detail, of an LCA depends on the subject and the intended use of the study. The depth and the breadth of LCA can differ considerably depending on the goal of a particular LCA. b) the inventory analysis phase: The life cycle inventory analysis phase (LCI phase) is the second phase of LCA. It is an inventory of input/output data with regard to the system being studied. It involves collection of the data necessary to meet the goals of the defined study c) the impact assessment phase: The life cycle impact assessment phase (LCIA) is the third phase of the LCA. The purpose of LCIA is to provide additional information to help assess a product system’s LCI results so as to better understand their environmental significance. d) the interpretation phase: Life cycle interpretation is the final phase of the LCA procedure, in which the results of an LCI or an LCIA, or both, are summarized and discussed as a basis for conclusions, recommendations and decision-making in accordance with the goal and scope definition.

Schoonschip (space&matter) consists of a total of 30 water plots, with 46 unique water dwellings for more than 100 residents (…) Each separate house is insulated and equipped with solar panels. Water pumps extract heat from the water in the canal to heat the homes. There is only one connection to the national energy grid, through which residents of Schoonschip trade their generated solar power. Each home has a battery which stores the energy surplus. Waste water from toilets and showers is treated separately and converted back into energy. Many homes also have a green roof, where residents can grow their own food (…) Schoonschip is not only sustainable in an ecological sense, but also socially: the residents work closely together to realize their residential area and coordinate their plans. They have agreed to renounce their personal cars and instead share electric cars together. The group also made a conscious search for diversity in the composition of residents. On that note, there are two ‘kangaroo houses’ in Schoonschip, where two households live together on one boat. Meanwhile, the houses are connected by a ‘smart jetty’ that serves as a pavement and meeting place (…) The district is connected with a smart grid, which is linked to a blockchain. With their own crypto coin – the Jouliette – the Schoonschip residents can trade the solar power that they generate with the neighbourhood’s 500 solar panels. They can also pay with it in other places around the Buiksloterham area, such as the cafe and restaurant at De Ceuvel, a circularity incubator which Space&Matter also initiated, developed and designed.
In September 2016 the government launched a Utilities Strategy promoting, among others, better utilisation of waste. Thus, the Utilities Strategy constitutes a key contribution to creating a more circular economy. The Strategy for Circular Economy, therefore, must be seen in close correlation with – and as a follow-up to – the Utilities Strategy (…) the government has decided to expose waste incineration and management of recyclable waste to competition (…) local authorities must put out for tender their household waste suitable for incineration (…) this way all parties have equal access to the waste (…) the in its Utilities Strategy the government has proposed a full competition exposure for the treatment of recyclable waste streams.
In regard to CE there are six areas of effort: 1. Strengthen enterprises as a driving force for circular transition/ 2. Support CE through data and digitization/ 3. Promote CE through design/ 4. Change consumption patterns through CE/ 5. Create a proper functioning market for waste and recycled raw materials/ 6. Get more value out of buildings and biomass
Category 3. Promote CE through design in particular, entails 2 of the 16 initiatives taken: a. incorporating circular economy into product policy and b. boosting Danish participation in European work on circular standards:
The design of products is crucial for the transition to a circular economy, since choices in the design phase of, e.g., materials and chemicals are decisive for the lifetime of the product, and whether components and materials can be used again with a high value (…) The eco-labels (Nordic Swan & EU flower) thereby make it easier for consumers, enterprises, and public authorities to purchase in a circular manner thereby contributing to a market-driven transition to a more circular economy.
An enhanced Danish effort in this standardisation work will make it possible to communicate knowledge from the European working groups on standards for circular economy to Danish enterprises who may be interested in having influence on the standardisation work.
Category 6 is also related to the construction industry through initiatives 13 & 14:
The building sector is challenged by a relatively high consumption of new raw materials for the production of construction materials and contents of substances of concern in buildings. The limited traceability of construction materials deteriorates the opportunities for recycling and reuse of high value. The embedded energy for new buildings can constitute up to 50 percent of the energy consumption over the entire life of the building. Today, no requirements are made for including construction materials’ so-called “embedded energy” – i.e. the sum of all energy used for production and waste management – in buildings’ energy calculation. If at some point of time an international building passport is developed, it will give better opportunities for the recycling of construction materials and a reduction of costs for maintenance and renovation.
Already today enterprises have an obligation to source-separate their waste so it can be recycled. But far from all enterprises comply with the rules. In fast and relatively unplanned demolitions construction materials are often mixed, which makes it difficult to separate the valuable parts of the waste. It also increases the risk that substances of concern are recycled or recovered instead of being managed safely in a landfill. Where existing rules focus on recycling, so-called “selective demolition” leads to a higher focus on the reuse of construction materials.
