Researchers at Chalmers have now demonstrated how the carbon atoms in mixed waste can replace all fossil raw materials in the production of new plastic. The recycling method is inspired by the natural carbon cycle and could eliminate the climate impact of plastic materials, or even clean the air of carbon dioxide.</b></p><strong>​</strong><img src="/sv/institutioner/see/nyheter/PublishingImages/HenrikThunman_191004_091.jpg" alt="Henrik Thunman" class="chalmersPosition-FloatRight" style="margin:5px" /><span style="background-color:initial"><strong>“There are enough carbon</strong> atoms in waste to meet the needs of all global plastic production. Using these atoms, we can decouple new plastic products from the supply of virgin fossil raw materials. If the process is powered by renewable energy, we also get plastic products with more than 95% lower climate impact than those produced today, which effectively means negative emissions for the entire system,” says Henrik Thunman, Professor of Energy Technology at Chalmers University of Technology and one of the authors of the study published in the Journal of Cleaner Production. </span><div><br /><span style="background-color:initial"></span><div>To achieve circular cycles, we need to make better use of the resources already in use in society. Henrik Thunman and his research team want to focus on an important resource that often goes up in smoke today: the carbon atoms in our waste, which are currently incinerated or end up in landfills instead of being recycled. This is made possible with technologies targeting the carbon contained in plastic, paper and wood wastes, with or without food residues, to create a raw material for the production of plastics with the same variety and quality as those currently produced from fossil raw materials. </div> <div><br /></div> <div><strong>Just like nature </strong></div> <div>Current plastic recycling methods are able to replace no more than 15-20% of the fossil raw material needed to meet society’s demand for plastic. The advanced methods proposed by the researchers are based on thermochemical technologies and involve the waste being heated to 600-800 degrees Celsius. The waste then turns into a gas, which after the addition of hydrogen can replace the building blocks of plastics. Using this recycling method could decouple new plastic products from the supply of new fossil raw materials.</div> <div>The researchers behind the study are developing a thermochemical recycling method that produces a gas which then can be used as a raw material in the same factories in which plastic products are currently being made from fossil oil or gas. Different types of waste, such as old plastic products and paper cups, with or without food residues, are put into the reactors at the Chalmers Power Central.</div> <div><br /></div> <div>“The key to more extensive recycling is to look at residual waste in a whole new way: as a raw material full of useful carbon atoms. The waste then acquires value, and you can create economic structures to collect and use the material as a raw material worldwide,” says Henrik Thunman. </div> <div>The principle of the process is inspired by the natural carbon cycle. Plants are broken down into carbon dioxide when they wither, and carbon dioxide, using the sun as an energy source and photosynthesis, then creates new plants. </div> <div><span style="background-color:initial">“H</span><span style="background-color:initial">owever, our technology differs from the way it works in nature because we don’t have to take the detour via the atmosphere to circulate the carbon in the form of carbon dioxide. All the carbon atoms we need for our plastic production can be found in our waste, and can be recycled using heat and electricity,” says Henrik Thunman. </span><br /></div> <div><br /></div> <div>The researchers’ calculations show that the energy to power such processes can be taken from renewable sources such as solar, wind, hydro power or biomass​, and they will be more energy-efficient than the systems in use today. It is also possible to extract excess heat from recycling processes, which in a circular system would compensate for the heat production currently derived from waste incineration, while eliminating the carbon dioxide emissions associated with energy recovery. </div> <div><br /></div> <div><strong>Can replace fossil raw materials</strong></div> <div>The research has been carried out as part of the FUTNERC* project.

Our plastic products are key to the transformation to a sustainable society, so it’s important for us to support research like this.

This is shown in a new study from Chalmers University of Technology. To promote the construction of larger systems and solar-as-a-service, changes in regulations are required. Such changes in regulations can contribute to the national goal of reaching one hundred percent renewable electricity production by the year 2040.</b></p>​In recent years, the market for self-produced solar energy has exploded in Sweden. The reason is, among other things, high electricity prices and the ongoing climate change. But for those who do not have a roof of their own or the financial conditions to invest in a solar system, the alternatives are limited.<br /><br />&quot;If we are to be able to increase the amount of solar energy in Sweden, we must ensure that more people have access to solar photovoltaics, not just those with detached houses who can afford to buy a system&quot;, says Amanda Bankel, doctoral student at the division of Innovation and R&amp;D Management at the Department of Technology Management and Economics, Chalmers University of Technology.<br /><br />The new study by Amanda Bankel and Ingrid Mignon, Associate Professor at the same division, has been published in the scientific journal Energy Policy. It shows that there is a lack of agreement in how researchers, policymakers and firms view solar business models. For instance, “community solar” business models have received much attention in research and policy at, for example, EU level. Community solar means that many people come together to produce, share, and consume renewable energy locally.<br /><br />However, such business models are hardly found among solar firms on the Swedish market. This does not imply that there are no energy communities in Sweden – only that firms do not see the need to design their business models for these customers. If Swedish policymakers want to increase the amount of solar energy through energy communities, they must also understand how firms that offer photovoltaic systems reason and what motivates them to specifically target energy communities, says Amanda Bankel.<br /><br />Other solutions that make it possible for customers to buy solar energy as a service through, for example, leasing, are also scarce in Sweden, despite having had a major impact in other countries, such as the US.<br /><br />&quot;Swedish policy instruments have favoured small-scale systems where the person who consumes the solar energy is the same one who buys and owns the system. Hence, it is not surprising that we see many firms offering these solutions and only a few that are aimed at people who do not want, or have the opportunity, to invest in their own system.&quot;<br /><br />&quot;If Sweden is to achieve its goal of 100 percent renewable electricity production by 2040, policymakers should ensure that more people have access to solar photovoltaics by promoting different types of solutions&quot;, says Amanda Bankel.<br /><div><div><br /></div> <div><img src="/sv/institutioner/tme/nyheter/PublishingImages/AmandaBankel_600.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px;width:300px;height:450px" /><img src="/sv/institutioner/tme/nyheter/PublishingImages/IngridJohanssonMignon_photoLaurentToudic_600.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px;width:300px;height:450px" /><br /><br /><br /><br /><br /></div> <br /><div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em><br /></em></div> <div><em>Amanda Bankel and Ingrid Johansson Mignon.<span style="display:inline-block"></span></em></div> <br /></div> <br /><strong>About community solar</strong><br />Community solar involves many people coming together to produce, share, and consume renewable energy locally.

Marimon Giovannetti sees many possibilities for the unique measurement method developed by the team: </div> <div><br /></div> <div><div><strong>&quot;At the Americas Cup in San Francisco Bay in 2013</strong>, it was the first time we saw a 72-foot sailing boat learning how to “fly” using hydrofoils during the competition. And since then, we've seen a huge increase in sailing boats with hydrofoils. With this new method and knowledge we are able to bring together a range of different branches of engineering – naval architecture, advanced materials and aeronautics as well as renewable energy.&quot;</div></div> <h2 class="chalmersElement-H2">Paving the way for hydrofoils on electric ferries </h2> <div>Hydrofoil technology is not in itself a novelty, but was developed as early as the 60s and 70s. Back then the focus was on getting boats to travel at as fast as possible and the hydrofoils were made of steel, a heavy material with higher maintenance costs. Today's modern hydrofoils are made of carbon fibre, a much lighter and stiffer material that can maintain its rigidity even under high loads – and can be tailored to the expected loads. Part of the research project was therefore to fully understand how a carbon fibre structure behaves underwater during different operational conditions. The research team's method developed in association with modern technology is now paving the way for the use of carbon fibre hydrofoils on larger passenger ships that can travel in a safe, controlled and climate-friendly way even at low speeds. <br /><br /></div> <div><strong>&quot;You want the foil to be as efficient as possible</strong>, which means carrying as much weight as possible at as low a speed as possible with the least resistance. Our next goal is to use this method when designing more efficient hydrofoils for ferries in the future,&quot; says Eslamdoost.</div> <div><br /></div> <div><strong>More about the scientific article </strong></div> <div>The study <a href="">&quot;Fluid-Structure Interaction of a Foiling Craft&quot;</a> has been published in the Journal of Marine Science and Engineering.

The isomer can then be stored in liquid form for later use when needed, such as at night or in winter. The researchers have refined the system to the point that it is now possible to store the energy for up to 18 years. A specially designed catalyst releases the saved energy as heat while returning the molecule to its original shape, so it can then be reused in the heating system.
