    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...

    Blockchain, AI and Sharing

    by Lisanne Huizing Due to the urbanization phenomenon, more people are going to move to cities. This will lead to more congestion of traffic, more pollution, and a necessity for more resources in cities among others. We will need more of everything than we have right now, in order to generate food and products. Resources are not endless, and they will become scarce in the future. “Smart Cities” have to solve this problem of rapid movement of goods, people and capital. By integrating technology, both cities’ and citizens’ behaviors can be understood. People can become involved and empowered by giving control over resources to more stakeholders by combining circular and smart technologies. It will give citizens the possibility to more actively govern their own resources at a lower geographical scale. Adaptive systems will be very beneficial for our future needs. Sharing & Circular Economy  With the Sharing Economy, a new phenomenon has arisen and it provides opportunities to redesign urban planning and access to locally shared resources. This will create a shift from possession-based, to a service-based economy. In order to use less resources in a growing and more demanding society, it will become necessary to make better use of the capacity of resources that is already existing.  When you look at a car that you only use in the weekends, for example, by sharing this with other people, it can also be used during the week. Once the car is optimally used and it comes to the end of its lifecycle, you can move towards the next step; circularity.  Although the Sharing Economy and Circular Economy are two different elements, they are connected. Because where the Sharing Economy ends, the Circular Economy begins. Together, they influence the taking shape of practices and optimization of processes. Cities can play a big role...

    New trends for circular materials

    Marco Cappellini’s speech is focused on three themes: the production of new materials and their end-life management, the transition to “products as services” and the measurement of the circularity. Trends in corporates According to a report by OCSE, it is estimated that the number of used resources will double by 2060. In particular, this fact involves specific sectors, as the packaging and the fashion ones, that are promising the recycling and the creation of biomaterials starting from 2020/2030. However, there are no doubts about the possibilities of recycling, but there could be problems about who carry out the process: some corporates produce recyclable products, but they are not recycled. For this reason, it exists the idea that the circular economy is uneconomic: but this is not the truth because multiple international cases prove the contrary. New business realities are proposing new custom materials. Many of these start from the principle of being “biomaterials”, material that are easily biodegradable and, or, compostable; there are other recyclable materials that are recyclable only through very specific processes and methods. This is very worrying because, it is possible to order recyclable products, but it is very hard for consumers to manage the end-life of the products. We can say that corporates have to play a more important role in managing the recycling of materials, for example, by creating a clause that specifies the end-life of the products in the patents. Matrec’s example is about a material made of recycled rubber by PFU, that is a very useful material, but it is undervalued. The input is to add value to the material: Matrec worked for new solutions that can improve sound and heat insulation performance, but they are also working on three-dimensionality. The aim is to increase the value of the materials on the market...

    “Old” and “New” Circular Economy

    This article is based on Roberto Zoboli’s speech during “Re-Think Forum”. Roberto Zoboli, during “ReThink Circular Economy Forum”, introduced some key elements to understand the Circular Economy, by distinguishing between “Old” and “New” Circular Economy. Some of the elements described in this article are coming from studies developed by the Inter-University research center called “SEEDS” – Sustainability Environmental Economics and Dynamics Studies – of which Catholic University is a member. Catholic University is also a partner of the European Topic Centre on Waste and Materials in a Green Economy, that develops studies and researches for the European Environment Agency (EEA). In particular, the Catholic University has contributed to the drafting of three reports for the EEA which include both technical and informative aspects: “Circular Economy in Europe, Developing the knowledge base”  “Circular by design, Products in the Circular Economy”  “The Circular Economy and the bioeconomy, Partners in sustainability”  In 2019 the fourth report of the EEA on the Circular Economy will be published. New behavioral patterns The idea of implementing the Circular Economy can force and orient the whole economic system towards new behavioral models. That means to move towards what the community like and what the community wants to prevail, from a sustainable, environmental and social point of view.  The OECD’s conceptual scheme is useful to frame the Circular Economy, it underlines three different levels of possible actions: The closure of the resource flows: best known as the “recovery and recycling process”, where the waste system has an important role, but it also includes the re-use and re-manufacturing of products; The slowdown of the use cycle: the elongation of the lifespan of products and the contrast of the fast aging, compared to what it is logical by the technical point of view and acceptable at the social level; Shrinking...

    Built environment

    This article is based on Guglielmo Carra’s speech during “Re-Think Forum”. Guglielmo Carra’s speech opened with the comparison of two pictures that portray the city of Shangai, one of them was taken in the mid-1990s and the other one only a few years ago. The difference is clear: the development of the city in the past 20 years was impressive and this trend is common in all urban contexts in Asia, Africa, South, Centre America and also in Europe. It is estimated that by 2050, about 70% of the global population will live inside these cities. It means that every week, a city of 1,6 million people is built. Cities are a place for people, but also a place where resources, coming from outside, are transported to be consumed with a linear approach. This change will impact the construction sector – that, at the current state, consumes 60% of resources and emit 40% of CO2. Improvements are possible since the constructions sector is the least automated ever, so it is also the least efficient, whose productivity of one hour is still equivalent to the one in 1946. Circular Economy can be the solution, in order to enhance the processes and the resources used, not only in the design of the utilization of the building but also by defining what will happen in the future to those materials and resources used for the construction. The 4 areas by Arup Carra presents some projects by Arup that revolve around 4 thematic areas: The regeneration of natural capital, which consists of transforming the city from a place that consumes resources, to a place where resources are produced and regenerated; The creation of open and shared processes by developing and implementing collaborative processes in addition to the promotion of actions and production chain processes....

    Cleantech

    In the common imagination, technology and environment can be seen as in contrast. On the one hand, the manufacturing industry with its energy-intensive production processes, which consume enormous amounts of resources, introduces toxic substances in exchange for air. On the other hand, the environment is seen as an element to be preserved and defended. The term technology itself, however, indicates the most efficient and economical use of available goods and tools. This is why it is not an oxymoron to talk about Cleantech, clean technologies, although it can be complex to define its fields of action in an exact manner. Cleantech: clean technology without borders The concept of Cleantech is difficult to define. If it is true that in a theoretical level it is a rather simple concept when you go into it, the possibilities become practically endless. In Cleantech, we can include all the innovations, regarding processes and products, that limit or completely eliminate the negative environmental impact of human action. We can talk about Cleantech when we are faced with technologies that deal with: • Collection and recycle of waste • Production of electricity from renewable sources • Rationalization of transport • Optimization of energy consumption • Reduction of packaging volumes • Limitation of resources used in the production process • Cutting emissions of pollutants into the atmosphere. In a Circular Economy perspective, Cleantech can, therefore, become any technology that limits energy; optimize their production and consumption processes; prevents waste eventually produced. In our analysis, we will focus on technologies that provide innovative energy production and storage. Artificial intelligence Forbes has dedicated to the world of new technologies for the creation of clean energy an article on the possible trends for 2019. Among the 6 trends that could emerge this year, the newspaper cites Artificial Intelligence, now pervasive...

    Biomaterials

    Plastic is probably humanity’s biggest failure. Even today hundreds of millions of tons are produced, despite the risks it entails, for humans and ecosystems. The solution is biomaterials, substances obtained from organic elements (from fruit to plants, to mushrooms), biodegradable and potentially zero-impact. Let’s find out why today it is increasingly necessary to identify these types of solution and why some companies have already focused their core business on biomaterials. The huge problem of plastics In spite of good intentions and proclamations, the creation of plastic does not seem to stop globally. Historically, the production of this material has established itself in the first decades of the twentieth century and has not stopped growing until at least 2010. Estimates tell us that plastic production has grown from 1.5 million tons, globally, from the 1930s to the 280 million tons in 2010, with a 38% growth in the last 10 years of the reference period. Statista also reports that in 2017 the figure has risen further to 348 million tons. According to the portal, the greatest growth in recent years has occurred in non-European countries: in 2002 global production was in fact 200 million tons (almost half compared to today), but Europe has contributed to this growth “only” for 8 million tons. The quantity of materials deriving from the oil that we put into the environment, therefore, becomes abnormal. According to UNEP, the UN environmental program, 8 million tons of plastic waste ends up in the oceans every year, an enormous amount of material that will remain there for decades, if not centuries. A plastic bag takes 20 years to degrade, while bottles and cutlery can take up to a thousand years. In reality, the problem is even more serious than it seems: in nature, nothing is created and nothing is...

    Circular Cities

    3 models for a sustainable city: the Circular Economy applied to the urban context A story of two cities. The first is the city as we have known it so far. The air made unbearable by pollution. It is very difficult to dispose of waste properly. Resources are widely wasted or underused. The other is a sustainable and circular city. Here the waste does not exist, the resources are used to the best according to the rules of the sharing economy and the energy required is completely produced from renewable sources. In the middle, there are the real cities, which are more or less similar to one or the other model. Cities are the first context in which it is essential to apply the terms of the Circular Economy. Because they represent an area in which it is perhaps easier to agree on its founding principles. Also because, above all, they are the place par excellence where humans live and will live. Why the cities? According to a World Bank report, 54% of the global population lives in urban areas and in cities, 85% of world GDP is produced (data: 2017). 75% of the natural resources are consumed here, 50% of the waste produced and greenhouse gas emissions equal to 60-80% of the total, according to different estimates. It is therefore clear that we need to start from the cities if we want to influence the way in which human beings live together and exploit resources. Also because the trend is destined to increase, by 2050 75% of the population will be living in cities. This means that even more funds will be invested in cities: infrastructures will be at the center of the growth strategies for the cities. Increasingly, natural resources, capitals, talents, and data will be concentrated in urban contexts....
