    By Maddalena Fava – Cooperativa Ziguele Every year, millions of tons of waste end up in the sea or in the port area; this phenomenon derives from: poor management and collection of waste, lack of infrastructure, little knowledge about the serious consequences on the natural habitat.Since the 1970s, the scientific community has been paying attention to this phenomenon, known as “marine litter“: “any durable material produced by man and abandoned in the marine environment; waste resulting from human activities whose destiny is to accumulate in the marine environment”. Fishing, aquaculture and recreational waste includes special waste (batteries, motor oils), organic waste (undersized species, waste), waste collected at sea (plastic, glass, paper and cardboard, fabric, wood, ferrous material).Currently, in the ports, this waste has a disorganized management: no space is available for storage and there are no operating methods for disposal. The reuse practices of the organic fraction are completely absent. Because of this, fishermen who collect waste from the sea, not finding suitable structures on the ground, abandon them back into the water, helping to increase environmental problems even in port areas. PRiSMa-Med is a cooperation project funded on the Interreg Maritime program, born precisely to combat these problems.The project involves several public and private partners located in three Italian regions, Liguria (Liguria Region, TICASS Scrl), Tuscany (Tuscany Region, Gestimar Scpa, CIRSPE) Sardinia (FLAG North Sardinia, Union Comuni Alta Gallura), and Corsica (Chamber of Commerce of Ajaccio and Southern Corsica).The objective is the characterization of the waste produced by fishing activities or collected at sea and to reinsert them in the production cycle through feasibility studies of recovery chains. We want to contribute to the reduction of waste and waste deriving from fishing, aquaculture and therefore from ports. To do this we need a system of governance, integrated management and...

    40South Energy

    By Michele Grassi – CEO & CTO of 40South Energy and Element Works Michele Grassi begins his speech by introducing 40South Energy, a project born in 2007, and Elements Works, a project born in 2014. The focus of 40South Energy is to produce renewable energy from sea waves. Over the years Elements Works has adopted a sustainable approach to the resources of the sea, including one called Integrated Coastal Zone Management (ICZM) whose goal is to establish a circular approach to the marine environment. In this sector it is possible to interact with various stakeholders, including those involved in fishfarming. Data collection is also essential to have a complete picture of the environment in which you operate. We need to move towards a continuous and punctual knowledge and data collection, which at the moment is lacking. The tools that can be used at the moment are sensors that are separated by large distances that only give a partial collection of information; then there are simulations like those of Aeneas; the collections on the spot field are not enough. Sea energy is different from wind energy; it is more distributed and predictable.In 2005, Grassi had the idea of a new approach to convert sea waves into electricity. This idea has become a project, and after about 10 years it has produced a machine called H24, so called because it can work 24/24. The first prototype of this machine was installed in Marina di Pisa. This technology is particularly useful for efficient dispatching and for isolated networks.Microgrids need less energy and generally have to bear higher costs per kWh, up to 0.50 cents per kWh and even more. In this context, machines with greater capital and management costs can be exploited, and commercial installations can be made, which are self-financed thanks to...

    By Thomas Lamberti – CEO of H2Boat Thomas Lamberti started his speech by introducing the current ecological situation, underlining that thanks to the abundance of energy provided by fossil sources, mankind has experienced unprecedented growth, thanks to a rapid but not sustainable economic development based on a linear model of continuous growth. The cycle of oil formation and its consumption travel on two incredibly different time scales. Furthermore, the rapid release of fossil CO2 has brought the planet into the Anthropocene era, characterized by strong ecological imbalances. The future of humanity will require more and more energy, but in a sustainable way, within a circular economy approach. Lamberti then continued his discussion focusing on the importance of hydrogen as a new source of energy; he explained that the hydrogen energy is among the most promising solutions for storing energy produced from renewable sources. H2Boat, is a spin-off of University of Genoa, born within the Department of Mechanical Engineering DIME and they work together on the technology transfer. H2Boat was born out of the desire to concretely realize its ideas at an industrial level, always maintaining the innovative and enterprising spirit that characterizes the university activity.Among his projects, Lamberti is researching and developing innovative solutions in order to introduce hydrogen technology on the market and make it available in every sector and to engineer energy systems for sailboats and motorboats, with the intention to start a successful entrepreneurial initiative able to contribute to the clearance of fuel cell and hydrogen technology in the nautical/naval world and beyond. The launch product of H2Boat is the Energy Pack, an energy storage system produced from renewable sources for sailboats. H2Boat Energy Pack is a system that uses hydrogen technology for autonomous pleasure boats – in particular sailboats – from the on-board electrical needs point...

    The incoming bioplastics

    By Giovanni Perotto – Engineer and Researcher at IIT Giovanni Perotto, Engineer and Researcher at the Italian Institute of Technology, focused his speech on smart materials and bioplastics, presenting a very interesting speech on technologies developed to convert plant residues into bioplastics. In Europe in 2016, 55 million tons of vegetable waste was produced. This waste is unfortunately thrown, composted or incinerated, all solutions with low added value when not expensive.Perotto explained how in a simple carrot there are materials that nature has engineered for the function that the vegetable must carry out: growing, having a structure, working as long as it is needed and then being reintegrated into the environment once its use is over. The macromolecules inside the carrot like cellulose, pectin, lignin and hemicellulose, have the function of supporting the various parts of the vegetable.The focus of the research being carried out regards the ability to harness these properties to produce short-lived objects (single use, packaging) instead of using plastic. The aim is to obtain solutions to be used as an alternative to common plastic, making entire supply chains such as packaging and disposable plastic more sustainable from an environmental point of view. At the same time this will improve the economic sustainability of the food supply chain, turning all the plant biomass, that is currently being disposed, into a resource. These are the focus areas of his research at the Smart Materials laboratory of the Italian Institute of Technology: the development of technologies necessary to carry out this conversion and the work on vegetable waste materials in order to obtain a suitable performance and to facilitate the implementation of new Circular Economy systems.The goal is to convert what is available as a waste from the food industry, but to achieve this we need to get the...

    By Tiziana Monterisi – RiceHouse CEO RiceHouse is a start-up born in 2016 that tackles the problem related to the construction building sector, that in EU is responsible for 40% of energy consumption, 36% of CO2 emissions and it generates 1/3 of all waste. The problem is widely acknowledged, and EU is setting clear guidelines for a resource-efficient and sustainable circular economy, with the vision of a decarbonised building stock by 2050. In addition, the UN SDGs (Sustainable Development Goals) objectives for 2030 are focusing on sustainable cities, responsible consumption, renewable energy and action on climate change. The company produces 100% natural building materials and finishing’s, that derive from by-products from rice cultivation and production. RiceHouse uses raw products such as rice straw, husk and bran, introduces them into the construction cycle and at the end of their service life they return in a circular way to the natural cycle. RiceHouse in an innovative way coordinates and controls a short supply chain, creating new economics from the field to the construction site. The company strongly believes that turning organic waste into a source of value is a key feature of the circular economy and from several years promotes the use of rice by-products from short supply chain. All products developed from the company are highly efficient in terms of energy, 100% natural, formaldeide free and made in Italy. Sustainable and green construction trend is growing fast with a prediction to increase 12% by 2026, with a total value of 254 b€ (50% in Europe). It clearly emerges that the value proposition of Ricehouse has all the features to satisfy the needs of the future demand: it proposes an offer in an economic sector in a phase of change that is based on values already incorporated and shared in different sectors...

    Energy from the Oceans

    By Gianmaria Sannino – Senior Researcher at ENEA Gianmaria Sannino opened his speech during ReThink – Circular Ocean Forum in Genoa, with a brief and current introduction concerning the correlation between climate change and sea-level rise, explaining how the oceans absorb heat and they expand by increasing their volume. In addition to melting glaciers, in fact, the oceans’ temperature increase, is the second reason that causes the raising of the level, which is among the causes of the disaster that took place in November in Venice. The sea can also be exploited as an intelligent energy source, Sannino showed a quote by Joseph Conrad from the book Typhoon, which says “… he had never seen the immeasurable force and excessive anger, the anger that passes and runs out without ever subsiding – the anger and fury of the irritated sea”, which turns out to be a fictionalized definition of what marine renewable energy is. Even Victor Hugo already in 1874, with a quote taken from the novel “Novantatrè”, emphasizes how the sea is a source of energy that the earth should make use of: “Think of the movement of the waves, the ebb and flow, the coming and going of the tides. What is the ocean? a huge lost force. How stupid the earth is, not to use the ocean! “ The global marine energy potential can be a very powerful resource, it is estimated that the amount of marine energy we can extract is equal to 1,200 TWh / year, while the global wave is estimated to be 29,500 TWh / year, these data are surprising if we consider that the current global electricity demand is 25,600 TWh / year. It would be easy to ask why it is not exploited, the first reason is that this energy is not distributed...

    Plastic offset is here

    Plastic offset is here. Here’s how to do it right by Peter Wang Hjemdahl (Co-Founder, rePurpose Global) A new paradigm is entering the environmental zeitgeist, and that paradigm is plastic offset. So what is it really, and how could it stem the global tide of plastic pollution? Put simply, for every dollar contributed by a polluter, a certain amount of plastic waste would be intercepted from the environment on your behalf as an individual or a company.  All across the developing world, waste management social enterprises have popped up to provide ethical & efficient solutions to our plastic epidemic, yet they are often underfunded and left unable to scale. Inspired by carbon credit, plastic offset is a transformative way of funding these innovations to accelerate our transition towards a circular economy.  Just like carbon, there are as many ways to do plastic offset wrong as ways to do it right. With the complex relationship between consumer responsibility and producer accountability, generating a truly meaningful impact is challenging yet entirely possible. From the landfills and alleyways of Mumbai to corporate headquarters in New York, we spent years understanding both local needs and the global systems that govern our waste. Here are 3 principles we have distilled on how to do plastic offset, right. Principle 1: Hit the problem where it hurts Anywhere in the developing world, if you pay attention to the kinds of plastic that are actually littering our streets, beaches, and landfills, you will notice a trend – it’s dominated by low-value plastic like to-go containers, candy wrappers, and plastic bags.  These materials are classified as low-value plastic because they are extremely difficult to recycle. Shanghai, Cairo, New Delhi, Nairobi, Jakarta – a vibrant informal recycling industry do exists in cities worldwide and employs tens of millions of workers who...

    Orange Fiber

    By Enrica Arena – Orange Fiber Co-founder Enrica Arena presents Orange Fiber, a company that produces a sustainable fabric similar to silk from citrus fruits. The material was born as an alternative product to classic cellulose, so the production is cut down over 70 million trees all. The developed product can be printed, colored and packaged, so brands don’t have to modify their suppliers and can be woven together with all other materials. The activity was born from the idea of ​​recovering what remains at the end of the industrial pressing of the orange for the production of the juice, which is considered a processing waste and which involves great costs for the companies in the sector and for the environment. In fact, 60% of the original weight of the fruit is considered waste but through a series of research carried out in collaboration with a university professor in the chemistry department of the Politecnico di Milano, it is currently possible to examine and patent an innovative process to transform the by-product of citrus fruits in a new resource capable of revolutionizing fashion in a sustainable and protected way to the resolution of problems related to the disposal. In the fashion field, 60% of the garments are made with materials deriving from the transformation of oil, and this not only causes environmental problems, but also links the value of materials to the oscillation of oil prices, by influencing the possibility that a collection is profitable or not for a brand. Furthermore, 25% of the products in the sector come from the cotton, a material whose production requires high quantities of water and soil, and which is often produced using pesticides. Organic cotton, on the other hand, has the disadvantage of needing more soil because it uses less pesticides but has...

    The energy of the Circular Economy

    By Giovanni Tula Giovanni Tula started his speech by introducing the focus of his presentation: circular projects linked to the energy world. The goal is to understand the status of renewable energies and their dissemination at the global level, by considering the 4 macro areas: storage, efficiency, the automation, and digitalization. The starting point is the comparison of the estimates regarding the dissemination of the renewable energies developed by the World Energy Agency in 2008 and 2017. As you can see from the image above, the estimates have more than doubled, the reason is that in 2017, with circa 13 years to spare, the estimate of the 2030 has already been reached, now the expectancy is to reach 4.718 GW installed in 2030. Actually, the estimates recently made could be underestimated because the renewable energies are becoming highly competitive thank to a strong reduction of the cost of production. For example, in the solar energy field, there has been an 83% reduction in the costs of the photovoltaic panels starting from 2010 till today. In the previous image it is highlighted the evolution of renewable energy sources compared to the fossil fuel, where it is estimated that the renewable could reach 64% of the overall energy resources. The storage Among the enabling elements of this revolution there is the “storage theme”. The batteries are essential to this evolution per 3 functions: Stabilization of the electricity grid Reduction of the imbalances on the generation side Offer of the energy in time of need on the consumer side The evolution of the lithium batteries in the last years has been important such that it has gone from some MW of power and storage of some minutes to a power of hundreds MW that can last for hours. The one that is impossible...

    An urgent opportunity

    By Francesco Castellano Francesco Castellano started his speech by explaining the reasons that drove him to create Tondo and ReThink. It all started from a beach, a place where he loved swimming, that place changed dramatically during the years because of the plastic and the waste. Trash created by human beings, which denotes, in part, the failure of the current system, a system that doesn’t take into account the impact of our actions on the environment. ReThink – Circular Economy Forum Without any doubt, we need to rethink our economic system, to reconsider its elements and the path we are following. The necessity to rethink led to the birth of “ReThink – Circular Economy Forum”, with the purpose to question some of the elements of our economic and industrial system and to show concrete applications of some interesting trends in the Circular Economy. Problems To understand the importance of the Circular Economy we need to show firstly the problems that humanity has to face at this moment. One of the most important issues is global warming caused by the CO2 issued for energetic production, for industrial activities and for transports. In particular, Castellano reported, that according to the last IPCC (Intergovernmental Panel on Climate Change)’s study, dated October 2018, to avoid the increase of the global temperature over 1.5°C (temperature that is considered the maximum limit to avoid effects that could be catastrophic on the global ecosystem and for the humanity in general), we have circa 12 years to reduce the 50% of the CO2 emissions and circa 30 years to delete them completely. Otherwise, some effects, that are already present, will expand more and more, with a devastating impact of drought, fire and flood. These events have already caused damages for 320 billion dollars in 2017 (https://newclimateeconomy.report/2018/). In addition,...

    Understand and Regenerate

    By Barbara Pollini Understand Barbara Pollini started her presentation by mentioning the contemporary philosopher Timothy Morton who coined the term “hyperobjects” to explain those interconnected phenomenons which have a wide vastness in time and space and that are incomprehensible for us. Climate change is one of them. In this perspective, designer’s ability to value material is important for the environmental impact of a product, also, in the complex world, the sustainability is not a steady-state, once it is reached you can’t keep it, it is a  dynamic threshold based on the continuous research. Designers, very often, are focused on some aspects of the project, and they ignore the life-cycle of the products and their materials; there aren’t many Italian universities that push the students to think about these issues and not many corporates of materials that explain information about the life-cycle of materials. Some designers adopt a critical approach and they reinvent some materials in order to find solutions that the market is not able to propose or in order to show a walkable path or an unresolved problem. Among these examples there is “Studio Swine” which created a stool made by plastic recovered at sea. It’s not part of a series production, but it wants to stimulate a critical thinking on an environment issue through the story of a material. At NABA, during Pollini’s lessons, there have been a lot of trials on DIY materials, that are organic or “made in waste”. Some of the projects are virtuous, such as “Peel Saver”, packaging for the street food made by potato’s peel, created by the students: Simone Caronni, Paolo Stefano Gentile and Pietro Gaeli. Also at Politecnico di Milano there are a lot of studies on DIY materials, Pollini is a tutor of the Metaprogetto Lab that took part at the...

Circular Economy

What is the circular economy and why it is important for everyone: citizens, businesses, institutions

While the circular economic motivations are clear, very often we don’t know how to implement it, as it is shown in the last report of the Global Fashion Agenda. The industry of fashion is the one which often finds difficult to marry an ecological approach. This is why it is even more important that the philosophy of the Circular Economy is linked to fashion: 20% of water waste resources comes from the fashion industry, at global level, and 10% of the emissions of anhydride carbon are due to textiles.

The reason why Circular Economy is spreading, is clear: the plastic residues that invade seas and oceans (and therefore all marine fauna), global warming, climate change are phenomena largely investigated by the scientific community and (almost) all the actors in the field realize that it is time to act in this direction.

The ‘how’ is missing, however, perhaps because there is no unambiguous definition of what the ‘current’ circular economy actually is: what are the objectives? What are the essential processes? What are the founding principles? In fact, similar questions are not at all trivial.

What is the Circular Economy

Where does Circular Economy come from? It is the economist Kenneth E. Boulding, who developed the first circular model for materials, in which the production has no residue, but everything is reintegrated and reused in the production circuit. It is 1966 when Boulding writes his article “The Economics of the Coming Spaceship Earth“.

Since then the concept has evolved and formalized in recent decades, especially for the emergence of climate change, defining the concept of a Circular Economy in the academic sphere. But where we are, it is still far from identifying a single and precise definition.

Julian Kircherr et al., Of the University of Utrecht, for example analyzed 114 definitions of Circular Economy, coming from scientific papers, identifying some frequent frames, but without being able to establish recurrent principles in the whole spectrum of definitions.

The 3 Rs: Reduction, Reuse, Recycling

Mainly, from the analysis of Kircherr et al. it emerges that the academic world sees the Circular Economy as a combination of 3Rs (a fourth is often added).

The three Rs are:

  • Reduction
  • Reuse
  • Recycling

By reduction, we mean the creation of production processes that aim directly at reducing the waste at the base. 3D printing can be an example in this sense, because the material used in the production model is only the one strictly necessary to create an object.

When we talk about reuse, instead, we assume the presence of an object that can no longer be used in its original function, which is than riused in a different area, almost without transformations. A glass bottle can be transformed, for example, into a design object (a lamp, for instance).

Finally, recycling is the best known and most common “R”. Here the idea is to exploit the material that constitutes an unusable object, to create something new. In other words, the plastic of water bottles is again transformed into a “raw” material for the creation of new products.

There is a fourth R, less mentioned in the documents analyzed by Utrecht researchers, which is the one of Recover. In this case, the waste is recovered to produce energy or to be composted, in the case of damp.

According to the analysis of Kircherr et al., most of the Circular Economy models discussed in scientific papers concern a combination of Recycling, Reuse and Reduction practices. In particular, recycling is mentioned in 79% of the definitions analyzed.

A holistic view of Circular Economy

Actually, the analyzed one seems an excessively narrow vision of Circular Economy. Also because it seems to consider exclusively the “traditional” productive process, while the ambition of the circularity should concern different human systems, including institutional ones.

The Utrecht researchers themselves offer a more varied definition of Circular Economy:

“[The EC] is an economic system that replaces the concept of “end of life” with reduction, or alternatively reuse, recycling and recovery of materials in production / distribution and consumption processes. This system operates at micro (products, companies, consumers), medium (eco-industrial park *) and macro (cities, regions, nations and so on), with the aim of producing sustainable development, while simultaneously creating greater environmental quality, prosperity and economic equality, for the benefit of current and future generations. It is implemented by new business models and responsible consumers”.

In this definition, a great number of actors are involved and the objectives of the circular economy are defined more precisely.

An even more comprehensive definition of EC is offered by the Ellen MacArthur Foundation, one of the most influential organizations on the subject. For the foundation, Circular Economy has the broader objective of “redefining economic growth”, which should focus on “positive benefits for the entire society”.

According to Ellen MacArthut, Circular Economy is based on three principles:

  • Create systems that permanently eliminate waste and pollution
  • Keep products and materials in use
  • Regenerate natural systems

Source: presentation of “The Circular Economy” by Professor Maria Zifaro (UNIMC)

The idea is that Circular Economy is an overall system changer. From the linear economy, which takes a product and turns it into a chain that inevitably leads it to waste, to a circular model, where everything is transformed and nothing is lost. Finally, a system that aims to bring new business opportunities, but also social and environmental benefits.

Can the impact of the Circular Economy be quantified?

As we have seen, the CE has objectives in different areas, from the environment to social equality. At the bottom of this definition, there is probably the misunderstanding that making the interests of the whole does not represent a profitable business. But, this is not supported by the data.

It is complex, even here, to define exactly the impact of the circularity on the economy, but the European Union has tried to draw up a balance. If the EU adopted at least three best practices (eco-design, waste prevention and re-use) of the circular model, it could achieve, compared to the usual economic scenario:

  • Net savings for businesses of around 600 billion euros (8% of annual turnover)
  • Increased resource productivity: + 30%
  • GDP increase: + 1%
  • Jobs created: two million

Meanwhile, the greenhouse gases released into the atmosphere from the manufacturing world would decrease by between 2 and 4 percent.

Three trends to keep an eye on

As we have seen, the Circular Economy is a vast and complex concept. It can involve companies, primarily, but it concerns everyone: from the ‘micro’ citizens / consumers to the ‘macro’ of states and conglomerates of states.

Reducing the scope on which to focus attention can be interesting to understand where and how the principles of the circular economy can be taken into consideration in practice. We have selected three of them, among the most interesting in the historical moment we are living, which we will mention here, but we will discuss later in as many articles on this blog.

The Cities

85% of GDP is produced in the cities and 75% of resources are consumed. We can say that they are the beating heart of the contemporary economy, where almost everything is produced and consumed.

It is therefore essential to think about the future of the Circular Economy starting from the cities. Even urban agglomerations must become circular. To succeed, they must exploit materials, technologies and flows that optimize and connect infrastructure and the people who live there, with their human and social capital.

Examples of this new paradigm are already in place: think of the discourse on smart cities, sustainable mobility, urban-farming.

The Materials

If cities are the “place” of the contemporary productive world, materials still represent the “thing”: each product is essentially a composition of materials. Even digital technologies need solid materials to work (smartphones, computers, servers).

For an effective transition to the circular economy, it is essential that the materials be rethought at the root. Recycling is useful but not enough: it is during the product design phase that we have to completely rethink the type of materials we use, their impact during use and the so-called end of life.

The need is therefore to design materials from scratch that can more easily be recycled or reused. One of the most interesting trends is the one concerning organic or bio-material materials, which use not only food waste and which have the advantage of being reproducible and biodegradable.

The Technologies

Technology is not opposed to the concept of sustainable growth, even if some business models have had a strongly deleterious impact on the ecosystem. In reality, exploiting the most of new information technologies can help us to reduce waste, simplify flows and optimize the use of resources and infrastructure.

Let’s think, for example, about the Internet of Things: the amount of data we receive from technological objects can help us, for example, to improve its energy performance.

Circular Economy: examples

We talked about the circular model in general. We have seen some concrete application areas. All that remains is to get to the heart of things and find out who made it. The stories of circular economy in the entrepreneurial sphere are many. We have selected five.


“Perpetua” is a pencil created by the Venetian company Alisea, made with graphite powder. The material, which has been named Zantech, is actually a waste obtained from the processes of molding electrodes.

The philosophy behind the creation of Perpetua is explained on the Alisea company website:

“We have been dealing for years with the recovery and re-use of customers’ corporate materials – the website states – with which we create objects for corporate communication. Our customers have always been a source of inspiration: so, when we were asked if we had an idea to dispose of several tons of graphite, coming from the processing of one of our customers, with high annual disposal costs, we thought: “Why not dispose of writing?”.


Aquafil (formerly Aquaram) is an Italian company that in the 1960s has staked everything on Nylon fiber, producing clothes first, then carpet. And which today leads the world in research into ecological nylon.

It is called Econyl, it is green nylon, which Aquafil produces infinitely zero emissions. The production process is based on the regeneration of caprolactam, a recycled raw material.

Giulio Bonazzi, 54, son of the company’s founder and now president and CEO, explains:

“We started with the fishing nets used in aquaculture, but the goal now is to get 100% ecological nylon regenerated from waste and not from petroleum derivatives. The strong idea is the circularity, creating a product that is a regenerated and can be disassembled and reused at the end of the cycle as a “second raw material”, for a new generation of products and without time limits”.


Alstom is a French train manufacturer, which in 2014 began to market the HealthHub diagnostic system. It is a maintenance prediction tool. In practice, by obtaining analytical data from a series of sensors, it is able to predict with greater precision how long the life cycle of trains, railway infrastructures and network signals can last.

Thanks to this system, it has been possible to extend the life cycle of trains and tracks. According to the company, the system allows a saving in the use of materials up to 15%, because it can signal when to change certain pieces only when it is strictly necessary.


FatLlama is a business that is based on the concept of sharing economy. In this context, real giants of the caliber of Airbnb were born, offering apartment sharing, and Uber, where they share their private cars.

FatLlama is a website that offers the exchange and sharing of practically everything: DIY tools, vehicles, cameras, drones, projectors, radios, and so on. Anyone who does not constantly use an object at home can share it on the platform and rent it for a certain period of time.

The startup was born in London in 2016 and in recent months has been facing an important expansion in the United States, starting in New York.

De Ceuvel

De Ceuvel‘s idea, instead, is to make an entire circular building. An old ferry anchored on the coasts of the city of Amsterdam has been transformed into a sustainable incubator, with 17 office spaces, where everything that is consumed is somehow revived.

The water is then filtered and used to irrigate the soil. Food waste becomes compost to be used as a fertilizer for the food that is offered by the kitchen. Finally, 150 photovoltaic panels make it a self-sufficient system.

Furthermore, the incubator is specialized in business that make the environmental vocation its own figure.
