Continuum targets facility capacity, transforms composite materials to advance wind blade recycling



Denmark-based Continuum Composite Recycling was founded to target the wind blade recycling initiative taking place across the globe. In order to abandon landfilling and to significantly reduce the CO2 emitted during current “recycling” processes like incineration and co-processing in cement facilities, Continuum is targeting composite material transformation to achieve more eco-friendly, fully recyclable wind turbine blades. The company is also anticipating the need for increased recycling capacity, expecting to develop several industrial-scale factories. Combined, Continuum believes it can reduce wind blade disposal by 100 million tonnes by 2050.

“As a society we are rightly focused on renewable energy production, however the subject of what to do with wind turbine blades in the aftermath of that production has not been effectively addressed,” Nicolas Derrien, CEO of Continuum Holdings ApS, says per the offshoreWIND.biz announcement. “We’re changing that, offering a recycling solution for the blades and a construction product that will outperform most other existing construction materials and be infinitely recyclable, and with the lowest carbon footprint in its class.”

To achieve its goals, Continuum is reusing composites via a CO2-neutral transformation technology — final material is said to be made up of 92% recycled material. This material is used to created composite panels for the construction industry and the manufacture of day-to-day products such as facades, industrial doors and kitchen countertops. Per a technical overview on the company’s website, Continuum describes its material transformation process:

  • Continuum organizes the transport and logistics of feedstocks from wind blades, automotive, marine and manufacturing waste — primarily glass fiber/polyurethane (GRP/PUR) — to its facility according to client needs.
  • During material reclamation and reprocessing, the company mechanically transforms and separates feedstock materials back into their raw, basic constituents through a variety of process such as cutting, milling, breaking, screening, gravity-separating, sorting, sifting, cleaning and storing. The system is said to optically sort out formerly embedded carbon fiber; all ferrous and non-ferrous metals and pollutants are separated and sent off for further recycling.
    • Fibers (glass, carbon fiber, etc.) are cut to <20 millimeters.
    • PUR and fillers are ground to <1.5 millimeters.
    • Binders (epoxies and resins) are also ground to <2 millimeters.
  • After these processes, Continuum creates new compound blends “based on the classified, reclaimed materials together with virgin resin(s) and/or other formaldehyde-free additives.” Additional material/blends can be developed, depending on application needs.
  • High-performance, high-density (single or multi-layered) panels are development. Mats comprising the blended composite materials are formed, pre-compressed and then placed under high heat and pressure in a continuous press to form the final product.

According to offshoreWIND.biz, Continuum, which is already present in Denmark and the U.K., plans to build six factories, the first of which will be in Esbjerg, Denmark, and is expected to be operational by the end of 2024, followed by a second factory in the U.K. After the first two facilities, the company plans to build four more by 2030 in France, Germany, Spain and Turkey. Continuum estimates that each facility will have the capacity to “recycle a minimum of 36,000 tonnes of EOL turbine blades per year and will be designed to be powered only by 100% green energy, with zero carbon emitting environments.”

The company says it will be able to begin taking end-of-life (EOL) wind blades by the end of 2023.

  Simonelli undertakes research to reuse composite materials Simonelli Group is currently undertaking a research and development project to reuse composite materials, that nowadays have a vast range of uses and applications thanks to their durability and longevity, but which are also very difficult to dispose of. The De-Manufacturing research project, developed by Delta srl and Simonelli Group, is part of the Marche Region’s Marche Applied Research Laboratory for Innovative Composites (MARLIC) platform in the context of ‘Sustainable manufacturing: eco-sustainability of products and processes for new materials and de-manufacturing’. “We are truly delighted to take an active part in this virtuous synergy, promoted and developed also within the MARLIC platform as advocates of a dual objective, to make a strong contribution to the transition towards a circular economy and to grow and develop the local industrial system,” says Fabio Ceccarani, Simonelli Group Managing Director. “The De-Manu

Unsaturated polyester (UP)  resin  is a low cost thermoset with excellent processing ability and  mechanical properties  that finds applications in fiber-reinforced polymer (FRP) materials. It also crosslinks readily in the presence of a catalyst such ketone peroxide, forming an even stronger and stiffer resin. Unfortunately, this also leads to lower  fracture toughness . Several methods to enhance the toughness of the cross-linked resin have been proposed; one such method involved blending with nano-fillers m

  In the dynamic realm of materials science, polymer nanocomposites have emerged as a revolutionary class of materials with unparalleled versatility and performance. From automotive engineering to biomedical technology, polymer nanocomposites are revolutionizing industries. This article explores the potential of polymer nanocomposites, highlighting their contributions to advancing materials science and supporting a sustainable future.1 What are Polymer Nanoparticles? Polymer nanoparticles, often termed nanofillers or nanoscale additives, are integral to polymer nanocomposites, imbuing them with exceptional properties. Ranging from 1 to 100 nanometers in diameter, these nanoparticles integrate into the polymer matrix, influencing mechanical strength, thermal conductivity, and electrical resistivity. Carbon-based nanoparticles like carbon nanotubes (CNTs) and graphene reinforce polymer matrices effectively, while clay nanoparticles enhance mechanical reinforcement and flame retardancy. M
