ECOBULK Excels at Ecomondo

ECOBULK was once again active at the Ecomondo 2019 environmental exhibition in Rimini, Italy.

ISWA Booth - Project Presentation

Dr. Gennaro Gentile, representing ECOBULK partner Istituto dei Polimeri, Compositi e Biomateriali (IPCB), was kind enough to help present the project to the visiting crowd. He addressed the work being done by IPCB to characterise and test the new circular materials being developed in the framework of the project. Circular materials must not only fit the properties required by the products, they must also meet circular criteria in terms of reusability and recyclability. In recent years, safety factors have gained increasing interest, with significant studies aimed to underline the presence of harmful substances in waste materials and to prevent their emission during the reprocessing/recycling of specific classes of wastes. A significant barrier to plastic recycling at the moment is the highly heterogenous composition of the recovered materials, particularly in the automotive shredded residue (ASR), which includes several immiscible polymer fractions and can contain a lot of contaminants. Further work is needed to improve separation. The IPCB investigations into materials fractions coming from municipal, furniture, construction, automotive and wind turbine waste has shown that these are, in general, well suited to be used as fillers in plastic matrices, resulting in new materials with appropriate mechanical properties. Care must be taken however, since in some cases toxic and other dangerous substances may be released both during the production and the use of the materials. Further work needs to be done to ensure better separation and avoid contaminants that can hinder recycling options.

EASME Stand - Networking

The Executive Agency for Small and Medium Enterprise (EASME) hosted 40 of their currently funded projects at their stand. This way the projects could network with the visitors to the exhibition as well as promote funding opportunities for future EASME calls for projects. ECOBULK took advantage of this good opportunity to present its work as well as network with other related circular projects which were also present there. Jose Uribe from partner ISWA was at the stand to introduce visitors to the project activities and the upcoming practical demonstrations of circular approaches to bulky composite materials and products, as well as answer any specific questions.

EASME Workshop on Plastics

Discussion panels organised by EASME gave the invited projects the chance to present themselves and discuss some of their challenges and lessons learnt. ECOBULK was present at the special Session on Supporting Actions to Improve Plastics Management.  The session showcased some of the front-running EU projects funded by Horizon 2020, among other funding schemes, which developed innovative solutions for plastics waste prevention, product design and recycling. ECOBULK was represented by Dr. Enrico Mangino, from CRF (Centro Ricerche Fiat).

Enrico talked about the challenges of using recycled plastics in the automotive industry, which until now has not implemented the use of recycled materials in any driver visible parts of cars due to aesthetic reasons. ECOBULK is changing that by introducing a dual layer construction in which virgin plastic coats a recycled core in central console parts. This way the visible quality is not compromised, and by ensuring compatibility between the virgin and recycled materials, it can also still be recycled in the same way. But at the moment, the flow of recycled materials is somewhat haphazard, depending on the availability of different types of waste. As Markku Vilkki, CEO of Conenor once put it, “… today my storage is full wind turbine blades, but next week it will be plastic pipes!”.

Dr Mangino also pointed out issues with materials that come from products with longer lifespans. In the automotive industry, using plastics recovered from End-of-Life (EOL) vehicles means using plastic compounds that were produced 10 to 20 years ago. In this case, the challenge is to prove that we can work with a wide and almost unpredictable array of sources and still provide a reliable output material.  Furthermore, regularly the market and regulations are updated to reflect the recognition of additives and substances which are no longer considered safe. These considerations are clearly reflected in the earlier mentioned work by Dr. Gentile and IPCB, which is a crucial contribution to ECOBULK and all other circular economy plastics initiatives.

Making Wind Turbine Blades Circular – the ECOBULK way.

Finnish Teknikka & Talous calls attention to the growing problem of wind turbine blades, and Conenor, ECOBULK partner, may have the solution.

Markku Vilkki, CEO of Conenor, has been working with ECOBULK on new circular approaches for composite materials. Composite materials, such as used in wind turbine blades, are considered difficult, if not impossible, to recycle. Most of these end up in landfills or being incinerated. Considering the annual production of composite materials is expected to reach $108 billion  by 2023 (BusinessWire), the expected destruction of value is enormous.

ISWA President Antonis Mavropoulos already called attention to the problem of wind turbine blades on his blog back in 2017. He stated that around 43 million tons of blade waste is expected to be generated worldwide by 2050, out of which China will have to manage 40 percent, Europe 25, the United States 16 and the rest of the world 19 percent.

Luckily, solutions are already being found. In his labs at Conenor, Vilkki is already producing extrusion profiles containing 35% FRP waste from wind turbines in a thermoplastic matrix. They have good physical properties, and best of all, they are fully circular. These will be demonstrated in the ECOBULK project which is now entering its demonstration phase. They will be used for lightweight and outdoor constructions, some of which will be placed at the new Kymiring motorsport park that is being built in Finland, and will host the Finnish MotoGP event in July 2020.

Vilkki will be presenting a paper at the Wind Turbine Blade Manufacture event in Dusseldorf between the 9th and 11th of December 2019: “Volume opportunities for re-manufacturing GFRP-waste; test results & applications”. This is a follow up from the previous year’s presentation – “Closing the loop for wind turbine blades” which can be downloaded here.

ECOBULK is a 4-year project, funded by the EU H2020 program. It combines 32 partners in a consortium of experts from product design, materials, production, logistics, business models, recycling and waste management. Together they have developed new circular design frameworks, materials and products that will be demonstrated across Europe in 2020. These products will be supported with new circular business models, reverse and circular logistics as well as a stakeholder platform that will be able supply advice on end of life options for composite products or materials.

Seriously Circular Gaming

Ecobulk partner FCBA has been thinking about how they can help companies become more circular. Sometimes companies need to be inspired by new ideas and possibilities, other times they need to consider technical challenges, and always they will have to take into account the business models that might have to be adapted to fit a circular value chain. At the latest Ecobulk meeting in Coventry, FCBA gave the partners a chance to play test their new educational game.

Both during the project and in the of work promoting circularity and sustainable models, it has been found that people sometimes learn better by doing, by trying something out. To help businesses think in a more circular way, they need to be challenged to start with an idea and then see how they can go forward with it. By creating a game around circular concepts, it is possible to challenge people to think about new ways of doing things in a safe format. The safety is not only due to the simulated nature of the exercise, but also the game aspect that removes the participants from their normal reality and allows them to be more creative and think in different ways than they normally would allow themselves to. FCBA likes to quote Einstein for this:

“Creativity is intelligence having fun!”

The game challenges participants to collect cards that represent concepts and materials that combined could form a credible circular product concept. Each player gets project and a challenge that defines some of the circular economy pillars that the project should fulfil. Players pick random concept cards from the table, each of them a real-life example of the circular pillars applied to a product or service. Players use the concepts as inspiration for proposing their own complete product that fulfils each pillar. After pitching their idea to their fellow players, the others decide how much money they should invest in the idea. Of course, in the end, the most investable idea wins.

The game works on several levels to increase the knowledge and circular thinking of the participants. At the more abstract level, some of the concept cards contain a pillar description instead of a concept, which gives players pause to reflect on what the pillars of the circular economy are.

  1. Sustainable Supply – material and business choices that consider environmental factors
  2. Eco-Design – taking into account all life cycle stages, including EOL, at design phase
  3. Industrial and territorial ecology – opportunistic exchange of energy flows and materials
  4. Functional economy – supply the function or use of a product
  5. Responsible consumption – mutualization or sharing of products and services
  6. Reusing – extending the product or part life cycle
  7. Recycling – turning waste into resources

At a more concrete level, each of the concepts presented during the game gives a tangible example of the fulfilment of the pillars. Players may draw on this inspiration by either applying similar solutions to their own similar challenges or considering when the particular approach might be appropriate depending on the product or context. Particularly surprising or inspiring concepts tend to become a short discussion item at the table, which engenders an interesting exchange of knowledge and experiences.

At a systems level, the players are forced to try to think of coherent product concepts that incorporate the different partial solutions that they have so far encountered. This is important, particularly from the Ecobulk perspective, the main goal of which is exactly to push the different enabling solutions into a demonstrable, working circular chain in real-life.

Finally, at an entertainment level, all those who participated in the game agreed it was seriously enjoyable to play!

Coventry, Cars, and Circular Economy

The innovative heart of the British auto industry is still beating.

Coventry is the traditional home of the British automotive industry. The industry reached its peak around 1950, when the UK was the second-largest car manufacturing country of the world. At this time there were 12 manufacturers in Coventry including then household names such as Rover, Jaguar and BMC (makers of the Mini) and it became known as the British Detroit. The size of the industry may have declined, but the knowledge has remained.  Coventry is emerging as a research centre with the opening of the National Automotive Innovation Centre as well as current expansion plans from JLR. In the midst of all this, ECOBULK gathered to finalise their plans to demonstrate the circular composite materials and prototypes that have been developed in the last 2 years.

MicroCab is one of the companies in Coventry working to rethink the car as a sustainable mode of transport for the future. Their vision is based on hydrogen fuel cells replacing the internal combustion engine and tailoring the design of the car to be highly efficient in its expected use. Within the ECOBULK consortium, they are pioneering a leasing business model that would allow them to maintain ownership of the car and sell mobility as a service. Following the circular philosophy, they are creating a modular design that fits with a regular maintenance schedule that exchanges parts, not just for maintenance, but also as an opportunity to modernise and upgrade the user experience over the multi-decade life of the car.

Maintaining ownership of the vehicle, MicroCab envisions various new opportunities that would allow them to increase the lifespan of the cars as well as the possibilities of re-using parts. The cars they design are highly efficient for their targeted use, but as we all well know, people’s use and expectations of a product are constantly changing. As the usage mode of the car changes, MicroCab will be able to switch out parts and make the car adaptable to the changing market needs without having to junk an old car or produce a whole new one.

Recycling is a growing issue with end of life vehicles, particularly in light of the increasing demands from governments to achieve higher re-use and recycling rates. At the end of life, a car is first stripped of any valuable major parts that are easily taken out. But after that, it is shredder time. The shredded particles are then separated out to Ferrous and Non-Ferrous metals, with a large mix of materials left over. The left-over materials contain a lot of plastics, but separating plastics, and in particular different types of plastics, can be quite difficult. However, with recycling targets now set at a minimum of 85%, this can only be possible by recycling these after-shredding plastics. TOMRA has been working together with Bellver and AIMPLAS to demonstrate the possibilities to to sort out these plastics in a way that is useful to recycling.

Interior fascia parts to be made with mixed plastic composites salvaged from ELV plastic waste.

Meanwhile partners FIAT and MAIER are getting to grips with the challenge of incorporating the salvaged plastics into internal car parts using composite materials. One of the core circular principles is to simplify and separate both parts and materials at the design stage to enable better re-use and re-cycling options at the end of life stage. However, vehicles reaching the end-of-life stage tend to be between 10 and 20 years old, which means that changes in design would only start affecting the availability of recycled materials at least 10 years from the start of production. To maintain the core practical demonstration purpose of the project, they will have to prove how they can take a large mix of plastic waste from 10 year old cars, and integrate it as efficiently as possible into the production of new parts. While designing to use mixed plastics might sound decidedly un-circular, it is perhaps the only practical demonstration that takes into account the fact that the automotive industry will always have to deal with design and material choices from at least a decade ago.

Ecobulk 2 Years on – M24 Meeting

Two years of Ecobulk where celebrated last week in Coventry, historical home of the British automotive industry. The meeting was hosted by the new project partners Warwick and Coventry University at the Scarman Conference Centre. Both partners will be contributing through their demonstrations of the new prototypes in furniture and construction sectors, as well input on the design of circular value chains.

The main aim of the meeting was to put all the pieces of the puzzle together for each of the planned demonstrations. Several exciting new concepts have been developed by the partners in the past 2 years which we expect will enable new highly circular materials and products to be produced. But the Ecobulk project is a large-scale demonstration initiative, and so an integral part of the challenge is to fit all the newly developed partial solutions into a coherent, circular chain that is feasible – not only technically, or theoretically, but also economically, and practically.

Furniture Sector

Moretti will be demonstrating the use of its modular furniture design concept for students and universities. They will be exploring business models that include the option to lease the furniture to their users, and where possible, recondition and re-use the returned furniture. With research from KEAS and Akzo-Nobel, the percentage of re-cycled particle board used in production can be significantly increased to accommodate the return of used furniture into the production lines.

Construction Sector

Conenor has developed some interesting new WPC materials using ‘waste’ materials from diverse sources such as wind turbine blades, discarded furniture, and plastic pipes. These will be used in several demonstration sites to create appealing light outdoor constructions and furniture. The materials are 100% recyclable into the same material at the end of life. With careful design and selection of fasteners, the individual components will be easily taken apart and replaced when necessary.

Automotive Sector

In the automotive sector, MicroCab is designing a modular platform for their hydrogen powered cars that allows the controlled and timely replacement of auto parts that not only maintain the quality but also modernise the user experience during the lifetime of the vehicle. Meanwhile Maier and Fiat are working on using materials and processes for their interior car parts that can re-use the plastics being retrieved by TOMRA, AIMPLAS and Bellver from shredded vehicles.

More to Come Soon ....

With the prototypes and demonstrations almost ready, we will be updating soon the information about where you can see the Ecobulk products being tested all across Europe.

Business models revisited

Creating circular value chains is not always straightforward, as choices for each stage have ripple effects on the entire chain. These effects can have secondary effects, and so the ripples go on. The only way to resolve this is to implement an iterative process.

This iterative process has been integrated into the design process for the ECOBULK prototypes and demonstrators. Initial prototype designs were created based on the Circular Design Framework and workshops from the previous consortium meeting. The next iteration in the process were the business model workshops at the M18 meeting in Valencia.

Design Workshops - Optimizing Business Models

EOCBULK Business Model Ambition versus Circularity

To start off with, the partners were asked to judge a number of different circular products and concepts that have been introduced into the market recently. Each of these was to be placed on two scales – one reflecting the level of circularity involved in the idea and another one assessing the level of ambition in the business model being used. The discussions served to calibrate the participants understanding and expectation of circular solutions and business models. After discussing several of these examples, the participants were then asked to consider the prototypes and demonstrations planned for ECOBULK.

Table setup Workshop

For this exercise the participants were divided into groups, each representing the different stakeholders in the system. There was a Materials table, a Manufacturing table, a Users table and an End-of-Life table. Each table was confronted with questions about what practical solutions or considerations would be important to increase the circularity of products in a particular sector.

 A list of requirements and questions would then emerge to could be directed to any of the other stakeholder tables. This list could then be passed around to the relevant stakeholders to answer and/or possibly provide further requests and questions to other tables. After several rounds, an overall shared picture could crystallize among the groups about the remaining obstacles and challenges that could be solved to improve the current circular concepts.

During the Construction workshop, some of the considerations revolved around the practicalities of separating waste streams for recovery, the importance of end-user behaviour in ensuring the availability of waste streams, and strategies for product life/cycle extension. For example, when trying to recover materials it is essential to have reliable data on what the material contents are, and it would be most helpful if materials were mixed as little possible, or at least were easily separable. To improve user attitudes and behaviour towards returning materials back into the cycle, communication was considered key – concepts like tagging materials with informative and inspiring messages like “in my next life I would like to be a spoon” to encourage people to be aware and engage with the life-cycles of their products. To solve for the collection logistical problem, the end-user engagement and strategies for life extension, a peer 2 peer network would allow end-users to match supply and demand in an organic way.

Slotted construction makes components easily separated for reuse and recovery.

The Automotive workshop produced some interesting discussions about the use preferences of car drivers which may be a barrier to shared car models, a more modular approach to vehicle design, and the manufacturers role in creating a wider acceptance of recycled materials used in aesthetic components. The idea of car sharing is quite popular, but still lacks wider appeal possibly because there is no possible customisation of the shared vehicle. This can be difficult to accept for many users who have as much an emotional relationship with their cars as they do a functional one. More modularity in design and equipment could help to increase the life span and maintain value by exchanging outdated parts with modern ones. Acceptance of recycled materials in aesthetic components could also be improved by manufacturers adapting their marketing to promote them – users have already accepted other forms of upcycled and recycled products as fashionable.

The partners will continue to develop and refine their prototypes as ECOBULK starts preparing for the demonstration phase of the project. Follow the progress by  signing up for our newsletter, and join us on our social media channels.

Coventive’s Quest for the Circular, Long Fibre Pellet

In the automotive industry lower weight means lower fuel consumption. One way to achieve lower weight is to replace heavy metal parts with lighter plastic ones, however, the replacement parts need to be made of materials offering similar structural performance. This is where composites come in. 

In particular, long fibre reinforced thermoplastic composites (LFTs) offer increased strength and toughness; and could be considered the best choice for structural performance for injection mouldable thermoplastic parts. These qualities basically translate to lower weight for parts at equal structural performance, a valuable economic and environmental advantage. 

Coventive have been working to develop first natural fibre, and now carbon fibre, LFT pellets. Their research progression, leading up to the practical implementation of their knowledge and processes for ECOBULK, was shared recently at the Long-Fibre Thermoplastics 2018 conference in Berlin. The work on recycled carbon fibre drew considerable interest from members of the automotive industry in the audience.

Coventive's LFT Journey

Coventive’s adventure into LFT’s started already with previous projects. Their original foray into this subject was more a feasibility study than anything else. With the project ECO-LFT, Coventive demonstrated their first ability to create a long fibre pellet that could be used for injection moulding. In a follow up project to develop a process for self-reinforced composites, PELTEC, they also by chance started experimenting with natural fibres. The experiment was eventually successful in delivering a pultrusion based process to create LFT pellets for which the material and moulded samples achieved all the technical specifications required by the manufacturers, except for one – price. The original recipe used continuous yarn fibre – which has a high added value and had a significant effect on the final pellet price. Coventive are working hard to replace the high value yarn with discontinuous, cheaper sources that will still maintain the same qualities.  This project will conclude in the spring of next year, by which time they expect to be able to supply production samples to those interested.

For ECOBULK, targeting the automotive industry, the collaboration with Coventive was obvious. Cooperations like this clearly highlight the value of demonstration projects that can bring separate research developments together and integrate them into a practical, circular market application. The knowledge and experience gained by Coventive in the pultrusion process for LFT’s can now be implemented to specifically develop alternative carbon fibre LFT pellets using recycled and waste materials. This would achieve the required structural properties for diverse uses in car parts, at a competitive price, lower weight, and with full circular credentials.

Their initial studies have shown that it should be possible to create LFT pellets using selvedge waste (virgin carbon fibre trimmings – production waste) and pyrolised carbon fibres from waste composite materials (recycled).  Using these sources, the fibres maintain slightly lower but similar properties, but offer a 35% – 50% reduction in price. 

The supply of selvedge (virgin carbon fibre trimmings) for this purpose might pose problems at scale, although at the moment this is considered production waste and has no commercial value. The pyrolised carbon fibres however, can probably count on a readily available supply from waste composites recyclers once the value of them has been established.

M18 ECOBULK Project Update

ECOBULK - Business Models Workshop - Valencia

The consortium gathered in Valencia for their regular 6 monthly meeting, hosted by partner ITENE at their offices in Paterna. After 18 months of hard work, the partners shared their progress, and collaborated on workshops designed to enhance the ECOBULK prototypes and demonstrations. 

Business and Design

The full first day was spent on intensive workshops specifically designed to challenge and stimulate the partners to further refine the business models for their circular prototypes. These workshops were a follow up to the previous circular design workshops in Koblenz (M12 – 06/2018) where the first concepts for the prototypes were crafted based on different circular strategies.

EOCBULK Business Model Ambition versus Circularity

The circular design process, perhaps by its very nature in having to integrate solutions from both up and down the value chain, requires an iterative approach where the original designs and concepts are revisited to ensure that the partial solutions being integrated are well matched and adjusted to each other where necessary. While this redesign iteration focused on the business model, the next ones will revisit and optimize material choices and then recovery options at end of life. Read more about the workshops.

ECOBULK Fastener Finder
The Fastener Finder developed by TUDelft

The meeting also featured presentations of some of the many deliverables due at this stage of the project. One of these was the finalised Circular Design framework developed by TUDelft, and a great new tool, the Fastener Finder, specifically designed to search for and provide information on the circularity of a wide range of fasteners and joining options for designers and manufacturers. This enables smarter, more circular choices to be made already at design time that make the flow of products and materials easier in the subsequent steps of the circular chain.


Of course, an essential part of circular design has to do with materials – which ones to choose and how to improve them for circular scenarios. In Valencia the partners presented the latest developments in this area. Granta has been working on the Materials Explorer database, which enables designers and manufacturers to choose from a wealth of materials and the resulting circular impact on the product from those choices. Further, our materials partners have continued developing and improving new materials for the ECOBULK project, based on pultrusion (Coventive), compounding (Tecnaro), agglomeration (Conenor), Airlaid (NTT) and hot press (KEAS/AKZO/CU) processes. These target different applications for the demonstrations, and are all now testing and improving their formulations for production.

Systems and Services

UPC, along with partners Exergy, ITENE, Granta and IRIS have been hard at work developing the digital systems support that will be necessary to enable the efficient circular flow of materials and products. Along with the required databases that will house the enormous amounts of data for the materials, their properties and their availability, they are also starting to design a decision support system that will help to make the most appropriate and efficient decisions at each stage of the circular chain. The system will first help in identifying the product or components, and then based on a reported failure mode can then propose possible actions such as repair, refurbishment or recycling by taking into account both economic and environmental costs of each action. 

Next Steps

During the next few months, the prototypes will be further refined and developed. They will go into production towards in 2019 so that they can be deployed to the demonstration sites by the end of next year. As the plans for the demonstrations become more concrete, we will be posting more information on what, where and how you will be able to experience the ECOBULK demo products.
