🔖 Topics: Circular Economy

🏢 Organizations: Sapienza University of Rome


The management of waste from electrical and electronic equipments (WEEEs) is a well-established topic in the extant literature. However, also the automotive sector is becoming a relevant source of WEEE, given the even more relevant presence of electronic components in cars. Due to new European environmental policies, end-of-life vehicles (ELVs) volumes are expected to grow in the next future, together with obsolete car electronics components. Hence, this work wants to assess the potential economic impact derived from car electronics recycling processes adopting the Net Present Value (NPV) as reference indicator. Through a detailed sensitivity and break-even point (BEP) analysis and a comparison of different cases, this work identifies a set of scenarios useful for industrial actors willing to enter the market of car electronics recycling. Results show an NPV varying from 136,570 to 607,621 €/t with a decisive role played by gold recovery.

‘Pushing the limits of innovation’ - 3D printed footwear showcased by Dior at Paris Fashion Week

🔖 Topics: 3D Printing, Laser Bed Power Fusion, Sustainability, Circular Economy

🏭 Vertical: Apparel

🏢 Organizations: Dior


The two different types of shoes created by Dior, derbys and boots, were printed using laser powder bed fusion technology, but the brand did not disclose the specific system used. The footwear was just about visible on the catwalk beneath long pants that models were wearing, but close-up images have now been released.

In a video shared by the official Dior Twitter account, a member of the design team spoke about the sustainability of the shoes: “What interested us here is that, once the tongue has been unstitched and the undersoles and laces have been removed, 80% of the material can be entirely reused for other purposes. It’s a circular approach.”

The Circular Economy vs. Industrial Automation

🔖 Topics: Circular Economy

🏢 Organizations: Novotek, ACTronics, CRS Holland


The Circular Economy is quickly permeating throughout the way consumers/end users think about manufacturing. Beyond end-of-life solutions, the circular economy at its heart is demonstrating the power of tapping into waste resources to create value, and new ‘product-as-a-service’ business models are highlighting the poer of new consumer demands.

Front-running companies are already pursuing circular strategies and successfully developing new, circular markets. This includes start-ups such as ACTronics, which remanufacturers automotive electronic equipment and CRS Holland, which recovers and recycles marine cable. It is becoming increasingly apparent that to remain competitive in the globl market and create a future-proof business, circular economy business strategies must be adopted.

Prototyping for the Circular Economy: Impact of Sustainability Regulations on Packaging Development

📅 Date:

✍️ Author: Craig Crossley

🔖 Topics: Sustainability, Circular Economy, Monomaterial


New environmental regulations are going to require manufacturers to redesign packaging so they are only one material (monomaterial) – which allows for increased ability to recycle as opposed to packaging made from multi-materials. This creates the need for rapid product development in order to completely redesign bottles and caps to be made of different materials than ever before. More companies are leaning on HDPE bottles and caps rather than the traditional PET bottle, which is going to cause a necessary redesign as the mechanical and physical properties of the materials are different.

Along with mono materials, tethered caps and closures are another shift in the world of manufacturing, designed to keep caps with their bottles to decrease the amount of litter made from single-use containers. These types of caps are pushing designers to get creative and develop entirely new caps and closures. This blog is going to give designers, product developers, and industry professionals the proper information for the future of packaging and how to leverage 3D printed tooling to stay ahead of the competition while maintaining proper prototyping procedures.

A hi-tech factory supports circular mushroom production

🏭 Vertical: Food

🏢 Organizations: Eclo


To grow mushrooms you need a ‘substrate’ – the base material colonised by the fungi’s mycelium from which the edible mushroom flowers. But sourcing substrates is a thorn in the side of commercial exotic mushroom growers, with supply chain issues dogging the market. This is where Belgian startup Eclo comes in. Normally, mushroom substrates are made from a wood base, grains, water, and mycelium. Eclo, by contrast, has found a way to replace the grains with organic waste from breweries and industrial bakeries. Not only is this a good use of recyled material that reduces the demand for virgin grain – the novel substrate is also high-yield, benefitting growers’ bottom lines.

Design for Sustainability

📅 Date:

🔖 Topics: Sustainability, Circular Economy

🏢 Organizations: Fractory


Typically, product designers select a few focuses, for instance, design for manufacturing (DFM), design for assembly (DFA) and design for reliability (DFR), and optimise those aspects of the product. Every design decision is evaluated in the light of the selected focus or focuses and relevant changes are then made taking the full life cycle of the product into account.

A sustainable alternative to this system is the circular economy. The main focus of this type of economic model is to reintroduce used parts as raw materials for new products. The intent is to move from a high-waste to a high-value model. Such a system is highly resource-efficient and reduces the effect of consumer demand on the exploration, pollution, and wastage of natural resources. Models such as biomimicry, cradle-to-cradle, product service systems (PSS), 4Rs, are all strategies that can provide design features to achieve a circular economy.

In recent years, the pulp and paper industry has gone from having a reputation of being dirty and environmentally unfriendly to being a leader in sustainability and pollution control. Now the technologies that enabled that transition are being used to help the textile industry too. And the players involved are restarting a shuttered paper mill in Sweden to make it happen, once more providing good-paying jobs for the area.

Renewcell is the Sweden-based scaleup at the center of it all. The company developed a sustainable process that recycles waste textiles into a product called Circulose, whose name is the tip-off that it’s aimed at making fashion circular.

How Eastman Strives for a Circular Plastics Economy

“Mechanical recycling—where you go out and take items like single-use bottles, chop, wash and re-meld them and put them back into textiles or bottles—can only really address a small portion of the plastics that are out there,” Crawford said. After a few cycles, the polymers in the products degrade and the process is no longer possible.

Instead, Eastman uses advanced, also known as molecular or chemical, recycling. “We unzip the plastic back to its basic building blocks, then purify those building blocks to create new materials,” Crawford said. This “creates an infinite loop because that polymer can go through that process time and time again.”

The next big shift will be an environmentally friendly movement dubbed the “circular auto factory.” According to some experts, the circular cars initiative will reshape the auto industry during the next two decades, as OEMs and suppliers attempt to achieve net-zero carbon emissions across the entire vehicle life cycle.

The term “circular car” refers to a theoretical vehicle that has efficiently maximized its use of aluminum, carbon-fiber composites, glass, fabric, rubber, steel, thermoplastics and other materials. Ideally, it would produce zero material waste and zero pollution during manufacture, utilization and disposal.

One of the key elements of a circular car factory is a closed-loop recycling program where disassembly lines are housed in the same facility as traditional final assembly lines. All vehicle components and materials are remanufactured, reused and recycled at the end of life.
