Floriade Almere 2022: The surplus value of C2C in area design and development strategies – Indah de Zwart (Student Haagse Hogeschool / Graduate Intern Floriade Almere)

This presentation gives insight in the changes needed in the planning of area design development in order to implement C2C principles and to create added value in the development, using the case of Floriade Almere. See the video registration of the discussion.

Parametric Analysis for Material Selection of a Cradle to Cradle inspired House in Switzerland – Shady Attia (Ass. Prof. of Sustainable Building Construction, Université de Liège)

It is clear that a ‘Cradle to Cradle House’  doesn’t exist. In this presentation attention is given to the Cradle to Cradle principle of renewable materials, taking into account total life cycle of potential building materials. In the discussion it became clear that current practices and Swiss laws on buildings and waste disposal are major limiting factors. See the video registration of the discussion.

Sustainable Buildings Design Lab – Shady Attia (Ass. Prof. of Sustainable Building Construction, Université de Liège)

An announcement of the newly founded Sustainable Buildings Design Lab at the Université de Liège. See the video registration of the discussion.

Registry for C2C Inspired Elements – Douglas Mulhall / Michiel Kulik (EPEA)

This is a presentation of the new Registry for C2C Inspired Elements in buildings. Information on The Registry can also be found at the RSM website. Go to minutes.

Prêt-à-Loger: TU Delft Solar Decathlon Submission 2014 – Nick Kerckhaert (Prêt-à-Loger team TU Delft)

Presentation in an early design stage of the TU Delft submission for Solar Decathlon. In the discussion, questions were asked about the desirability of making ‘ugly’ houses last longer, and was remarked that it is important to not only attach something to the existing house, but also to improve the overall quality: of the public space, of the daylight levels inside. 

After this presentation, a lot of work is done on the design and execution. Finally, the Prêt-à-Loger won the third prize on the competition. More information on

The Breathing Green Pavilion – Lara Smits (TU Delft Architecture student)

This concept is received very positively on the C2C Lab and it has been recommended to transform this idea into a business model. Go to minutes.

Redesign of printer cartridges – Kay van ‘t Hof (TU Delft Industrial Design student)

This is an attempt to redesign the printer cartridge using the C2C principles. In the discussion it became clear that the major problem is the fact that reuse or refill is not commercially interesting for the manufacturer. Take back systems in collaboration with other partners are needed. Go to minutes.

Generic Approach Computing for Cradle to Cradle – Özer Ciftcioglu and Michael Bitterman (TU Delft, prof. and researcher Design Informatics)

A computational approach for complex C2C design problems is proposed. In the discussion, four possible outcomes of using this computational method in C2C came up: for optimizing integration multiple goals, for selecting between multiple ‘best’ options, for measuring total result, and as an extra forcing to clarify the variables at soft and hard level. These four need to be defined very distinctively to companies which want to use this. It is also remarked that the outcome is very much dependent on good information. The environment needs to be translated into parameters for input, which will be a major challenge and it is thinkable that this computational model not simplifies the human work, but only shift it. Another major issue is how to deal with (inevitable) false assumptions. Go to minutes.

Nature Inspired Design: Case study of Closed-loop Design – Ingrid de Pauw (TU Delft, PhD researcher Design Engineering)

This is received as a good example of implementing C2C. Some tips are given in the discussion, including implementing the principle ‘celebrate diversity’, and the warning that with using LCA for quantifying the results of the design you will ‘penalize’ yourself. Go to minutes.

Inspiration for Decline Areas – Ineke Lemmen (Ministry of Finance)

This presentation is from a traditional sustainability approach, not using C2C principles. In the discussion is tried to implement this. The first cause for shrinking areas is because people do not see future in their area; this can be caused by the ‘less bad’ approach. By starting with defining positive goals, new inspiration can start. The next step is to communicate this and involve the right parties. There is a huge financial component in this problem, the financial parties need to be involved strongly in new development plans. Go to minutes.

Building Integrated Greenhouses – Anouk Schrouwen (Wageningen University)

This presentation provides very useful information on integrating buildings with greenhouses. In the C2C Lab Session is mentioned that the next step will be to integrate the different results, and to implement this knowledge in business models and real examples. Also, it is important to state goals again in every project (celebrating diversity). Go to minutes.

World Views and Ecology – Annick Hedlund-de Witt (VU Amsterdam, Environmental Policy Analysis)

The perspective of world views (traditional, modern, post-modern or post-post-modern) is relevant in communicating C2C to people. Go to minutes.

Closing material cycles in the building envelope – Ifigeneia Riga (TU Delft, student Architectural Engineering)

Presentation of project for redesigning the envelope of an existing building: hotel in Scheveningen harbour, applying a C2C-inspired approach to materials. Go to minutes.

Picnic Set Ameland – Swen van Klaarbergen (TU Delft, student Industrial Design)

A business model and product is developed to get ‘a real Ameland experience’, Ameland being a Wadden island. The product is a picnic bag, in the form of the lighthouse, made and recycled on the island itself and available for rental (also in combination with bicycle rent). Go to minutes.

Happy Healthy School – Michiel Kulik (TU Delft, student Architectural Engineering)

Happy healthy school is a concept for combining schools with greenhouses. Classrooms are very unhealthy in terms of CO2 concentration. The broadleaf vegetation in a greenhouse can transfer the CO2 into O2, while the coniferous vegetation can remove the finedust. The result is 100% clean air. There are also other benefits: in greenhouses food can grow and vegetation can be used for education purposes or to get children in contact with nature. A pilot is applied at the Utrecht High School. Go to minutes.

Tableware design from a C2C perspective – Tim Overkamp (TU Delft, student Industrial Design)

Theoretical project on the use and reuse of canteen tableware at the TU Delft. It is the challenge to find something with a positive reward system. Go to minutes.

C2C in Supply Chain Management – Sarah Herms and Eliza Panagiotidou (TU Delft, students Industrial Ecology)

The C2C approach can be useful to apply to Supply Chain Management. It is recommended to start with a supply chain and then start optimising, keeping the integrity of the material, and keeping in mind that the chain is not the goal, but that the purpose is to fill human needs. Go to minutes.

Adaptive Building Structures – Andries van Westenbrugge (TU Delft, student Civil Engineering)

The model of a tree, adapting itself, can be applied to bearing structures. Go to minutes.
