Transform Single-use Waste Plastic into Valuable Products

On Thursday, November 4, 2021 you are most welcome to join the webinar about TRANSFORM-CE in English. The project team will then tell you what it is looking for and provide examples of business support opportunities.

Opportunity for your business?
Interreg NW Europe funded project, TRANSFORM-CE, launches the first in its informative webinar series on turning single-use plastic waste into valuable new products. It will introduce two innovative technologies, additive manufacturing and intrusion-extrusion moulding, which are facilitating the transformation of this common waste stream into the feedstock for countless applications, from roof tiles and decking to architectural models and 3D printed components.  This is a fantastic opportunity for businesses, manufacturers and government authorities interested in learning more about TRANSFORM-CE and the potential benefits of transitioning to a circular economy business model. The project partners also welcome designers, creatives and members of the public who are interested in exploring the potential of single use plastic waste.

New technologies for a circular economy of plastic?
TRANSFORM-CE is currently running two pilots to turn single-use plastic waste into raw plastic feedstock: an AM R&D centre in Greater Manchester (United Kingdom) and an IEM plastic factory in Almere (The Netherlands). A third AM facility, a prototyping centre, will open early 2022 in Belgium. Work has already begun, using the feedstock to manufacture products like outdoor furniture, building materials and even houses. Once the technology is scaled up, TRANSFORM-CE’s partners will have the potential to develop circular economy business models and stimulate new secondary material markets across North West Europe and beyond. Waste plastic can be re-purposed and revalued.

Who will speak?
• Rhiannon Hunt: Circular Economy Project Manager at Manchester Metropolitan University, UK.
• Bram Peters: Owner of the Green Plastic Factory Almere and Save Plastics, the Netherlands.
• Malou van der Vegt: Researcher and Lecturer in the Circular Economy at the Utrecht University of Applied Sciences, the Netherlands.
• Evert-Jan Velzing: Scientist and Lecturer at the Utrecht University of Applied Sciences, the Netherlands.

David Greenfield will be the facilitator of the webinar. He is managing director and founder of SOcial, ENvironmental & EConomic Solutions (SOENECS) Ltd.

What will be preliminary programme?
14:00 Opening address and introduction to TRANSFORM-CE
14:05 Transforming single-use plastic waste into filament for additive manufacturing
14:15 Creating new products from single-use plastic waste using intrusion-extrusion
moulding
14:25 The business case for adopting circular economy solutions
14:45 Be a part of TRANSFORM-CE; opportunities for businesses
15:00 Q&A

Danish Researcher looking for inspiration in Amsterdam

Featured image

Hi community,

I am looking for inspiration on nature-based solutions in Amsterdam. I have a full day in Amsterdam the 6 th of October 2021, and I would love to visit locations having implemented nature-based solutions in impressive ways. I am curious about how Amsterdam has worked with urban biodiversity and how Amsterdam has implemented large-scale nature-based solutions, e.g. green corridors or other kinds of 'wild nature' in the city, for the benefit of people and other species :)

I hope you can help me with advices on where to go and whom to talk with?

My research project: Biocities of the future
The ambition is to develop initiatives that can help urban stakeholders integrate nature-based ideas and design strategies in urban development. The project includes prototyping a dialogue tool and testing if it could supplement the international certification tool DGNB Urban Districts.

I study how nature-based ideas integrate in urban development of today, and I identify some of the main drivers, paradoxes, consequences, and challenges, related to these integrations. The project focus is urban development inspired by nature’s ability to regenerate, through e.g., biomimicry and regenerative and biophilic design thinking.

My research is based on a cooperation between three Danish organisations:
City & Port - develop large scale urban areas in Copenhagen, DK
The Royal Danish Academy - Architecture, Design, Conservation
Bloxhub Science Forum - a nordic innovation hub for sustainable urbanization

Urban mining and circular construction – what, why, and how it works

Featured image

When the functional lifetime of an object is over, its highest possible value should be retained. This shortens supply chains, increases resilience, and safeguards the environment from manufacturing-related emissions.

Currently, the construction sector is optimized for a linear supply chain. This is mainly due to a lack of information on harvestable materials and their reuse value.

Learn more about urban mining and how it can help us move towards a circular economy.

Ready to meet the winners of the No Wast Challenge and their ground-breaking ideas?

Featured image

Ready to meet the winners of the WDCD No Waste Challenge? Earlier this evening, a total of 16 ground-breaking ideas were selected for the top prize, representing a wide range of strategies for reducing waste and its impact on the planet. Each winning team will now gain access to €10.000 in funding and an extensive development programme designed to launch their ideas into action.

“The quality and range of entries we’ve seen in this Challenge is remarkable,” comments Richard van der Laken, co-founder and creative director of What Design Can Do. “In a turbulent year, it’s particularly inspiring to see that the creative community is willing and able to break away from decades of linear thinking and bad design. I’m hopeful that others in the industry will follow their lead.”

Revolutionizing the the taking and making
The winners were determined by an international jury who reviewed every project from a list of 85 high-potential nominees.  Among the ideas to take home the top prize are solutions that focus on the production process – aiming to revolutionise the taking and making of all the things we use and eat. Sustrato (Mexico), for example, combines traditional craft, contemporary design and waste from the pineapple industry to develop a range of sustainable bioplastics. Modern Synthesis (UK) makes use of a similar waste stream, this time from apple farms, to feed microbes that grow fully circular fibers for the fashion industry.

Adressing the underlying problem of consumerism
Meanwhile, other winners are unified by their desire to uproot entire value systems. These projects are looking to prevent waste by addressing the underlying problem of consumerism. Reparar.org (Argentina) for example, is a service which connects individuals to local cobblers and repair shops, working to promote a culture of care and the right-to-repair. Similarly, Project R (Japan), is a community centre that empowers citizens to learn about circular techniques and lifestyles. Together, these winners suggest inventive ways for us to reconcile what we want with what the planet needs. In doing so, they also help to redefine design as a tool that can be restorative and regenerative, instead of merely productive or destructive. Congratulations to all!

ABOUT THE NO WASTE CHALLENGE

What Design Can Do and IKEA Foundation launched the No Waste Challenge in January 2021, calling for bold solutions to address the enormous impact of waste on climate change. The competition was open to innovators everywhere, and offered three design briefs tackling different aspects of our take-make-waste economy. In April, the open call ended with an exceptional 1409 submissions from creatives in more than 100 countries. As part of the No Waste Challenge award package, sixteen winners will now enter a development programme co-created by Impact Hub, which will propel their projects through 2022.

Almeerse basisschool De Verwondering meest duurzame project van Nederland!

Featured image

Ecologische basisschool De Verwondering in Almere Hout heeft de Gouden Kikker gewonnen: de prijs voor het meest duurzame project van Nederland.

De jury van de Duurzaam Bouwen Awards vindt De Verwondering een inspirerend voorbeeld van duurzaam maatschappelijk vastgoed op zeer hoog niveau én in de breedste zin van het woord. Niet alleen door de keuze van natuurlijke materialen, systemen en bouwmethoden, maar ook door de ontwerpfilosofie. Het natuurinclusieve schoolplein is een ecosysteem op zich, met nestgelegenheden voor vogels en insecten, lokale flora en een kleine baai. De leerlingen zien zelf hoe hun school is gebouwd, welke materialen zijn toegepast en hoe het van energie wordt voorzien.

Met dit alles, is het project niet alleen een inspiratie voor de leerlingen én medewerkers van de school, maar ook voor de rest van Nederland!

Esther 't Hoen, jurylid en projectleider circulaire bouweconomie van het ministerie van BZK, mocht de award aan de architect, Daan Bruggink van ORGA architect overhandigen. “De samenwerking tussen de Gemeente Almere en Stichting Prisma Almere, de opdrachtgevers en Paula van Kuijk, de directrice van de school en de installateur, heeft geleid tot dit resultaat.”

We zijn trots op het project en uiteraard op de samenwerking tussen de verschillende partijen wat heeft geleid tot een prachtig resultaat. Mooi dat dit, mede dankzij de Gouden Kikker van de Nederlandse Duurzaam Bouwen Awards, nationaal de aandacht krijgt. De awards worden mede mogelijk gemaakt door abcnova, Stichting W/E adviseurs duurzaam bouwen, FSC Nederland en Duurzaam Gebouwd.

Verder hebben meegewerkt aan De Verwondering: Bladgroen, Van Norel bouwgroep, Lüning Ingenieurs in houtconstructies, Nieman Groep, TDS Engineering, Projectum Inrichten B.V., GoedGeplant en uiteraard iedereen bij De Verwondering!

Tools for circular construction

Featured image

The impact of circular principles on the construction sector will be large and beneficial because buildings are responsible for more than 50% of the total use of materials on earth, including valuable specimen such as steel, copper, aluminium and zinc.

The picture above – the interior of the Circle pavilion of the ABN-AMRO bank in Amsterdam is an example of a new building that uses as many existing components as possible and new components of the building are designed to be reused. Think of:

• 1200 m2 of wooden floors
• Partition walls of a demolished building
• 16.000 garments of employees for isolation purposes

By circular construction we mean designing, building and demolishing a building in such a way that, in addition to the high-quality reuse of materials, justice is done to sustainability ambitions in the field of energy, water, and biodiversity and ecosystems.

New materials are often more expensive than new ones
In case of demolishment, nowadays many components are already reused, but at a very low level, for instance concrete and stones as the foundation of new roads. Apart from the limited necessity to construct many new roads, this type of recycling destroys the intrinsic quality of materials and does not diminish the use of new materials. The biggest problem is that recycled materials are often more expensive than new ones.

Evidently, progress can be made by planning, designing, developing, and building circular buildings. A number of options are mentioned below.

Dedicated urban planning
Challenges for planning are the use of inner-city vacant land and issuing mandatory requirements regarding the construction of new buildings, for instance the use of less cement, glass and steel, the mandatory application of a certain percentage of reused materials, and becoming energy positive or at least energy-neutral. Switching to sustainable timber is an option for 90% of homes and 70% of offices being built.

Mandatory reuse of existing components
Reuse of existing materials means that glass is reused as glass and concrete pillars as pillars. The same applies to doors, frames, carpets, wall-cladding materials and so on. To start with, after demolishment all materials must be selected, cleaned, registered, and stored in new-to-develop warehouses. A materials passport, which contains an overview of all materials and components that are used to construct of a house or building, is a useful tool as well. The obligation to reuse a large percentage of existing components has far-reaching consequences for the design and construction of new houses.

Industrial production and 3D printing
Construction of components in factories, deploying industrial processes, will reduce costs by 30 percent and the delivery time by at least 50 percent. In 2014, the Chinese company WinSun printed and assembled ten houses, each 195 square meters, in 24 hours, for an amount of €5,000 per house[1]. The company used 30 - 60 percent less material than in traditional construction. The “ink” for their 3D printers is a mixture of dry cement and construction waste. WinSun plans to open 100 recycling plants in China to convert waste into cost-efficient ink. This video below demonstrates the printing activities of WinSun

Sharing space
The size of apartments will decrease, partly due to costs, but also because of the presence of shared guest rooms, lounge areas and terraces for working and socializing, spaces for washing and drying laundry. The need for office space will decrease rapidly due to sharing space and working home. Already now, IBM has only one desk available for 12 employees. Given the presence of 300,000 employees, this has led worldwide to savings on real estate of around € 1 billion in the past 10 years.

Modularity and durability
A key barrier for better use of floor space is the lack of flexibility in the design of buildings and room configurations. A modular design, which provides for easy replacement of partitions and placement of complete pre-fab units (kitchens and bathrooms, walls, and roofs as well) facilitates adjustments in case of new construction or as the use of a building changes. DIRTT builds interior components that are modular and standardized and offer maximum interchangeability in both existing and new buildings[2]. This video gives an impression of the production and application of these flexible and inexpensive solutions.

Forget new construction at all
Anyway, a first step is more efficient use of existing buildings and houses.
As families become smaller and offices need less space, existing space becomes underused. Many thousands of one family houses can be transformed in apartments. Well-thought adjustments to the lay-out of existing houses and buildings can improve their efficiency without reducing their functionality and amenity. Look here for inspiring examples.

I will regularly share with you ‘snapshots’ of the challenge to bring social and ecological sustainable cities closer using technology if helpful. These posts represent findings, updates, and supplements of my e-book Humane cities. Always humane. Smart if helpful. The English version of this book can be downloaded for free below.

The building for the Temporary Courthouse in Amsterdam will be relocated to Enschede!

Featured image

Over the coming months, the building of the Temporary Courthouse Amsterdam will be dismantled and completely reassembled on 'Kennispark Twente' (the area of Business & Science Park/Campus UT) in Enschede. There, it will have a new function as an office and research facility.

The temporary accommodation provided the Amsterdam judiciary continuity during the construction of the new permanent court. Now that this new home has been completed, the building will move as planned. At the time, the Central Government Real Estate Agency (RVB) tendered the assignment as a Design, Build, Maintain & Remove contract, which was realized by dpcp, a cooperation between cepezedprojects and Du Prie Bouw & Ontwikkeling. cepezed and cepezedinterior designed the building and Du Prie took care of the execution.

National Sustainability Award Steel after completion
Importantly because of its high degree of circularity, it won both the Amsterdam Architecture Prize (Golden AAP) and the National Sustainability Award Steel after completion. Also, in the report 'Circular Buildings – a measurement method for detachability' it scores the highest of all tested projects. The demountable construction and floors, which cepezed designed in close collaboration with IMd Consulting Engineers, play an important role in this.

Dismantling and reassembly with a 3D model
Yesterday saw the handover of the key from the RVB to dpcp, which heralds the new phase of the building. For the relocation, dpcp called in the expertise and experience of Lagemaat from Heerde, a company with a solid background in the dismantling and reassembly of buildings. Through a unique coding based on the 3D model and a 3D scan, the precise position of each part is known. Smaller elements are transported in containers and larger ones, such as the walkway, are loaded directly onto trucks. Lagemaat processes materials that are not reused in other projects. A minimal amount will be recycled in a high-quality manner. The dismantling period starts today already. The building is expected to be taken into use by the Overijssel Restructuring Company in early 2022.
