    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...

    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...

    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...
