Oh, patents! FabBRICK® Projects

 Copyright © Françoise Herrmann

In 2023, five years after its inception, FabBRICK® had produced 152,000 bricks. A quantity of bricks that amounted to 32 tons of upcycled, used textiles. In other words, enough brick orders to justify expanding the company’s size, and to give everyone working for FabBRICK® a clear sense of doing good in the world. A positive impact on yet another serious aspect of environmental pollution, considering how much used and/or waste textiles had been given a second life in stunning wall cladding and furniture projects, such as those exemplified below. 

After all, 4 to 5.8 million tons of used textiles are discarded each year, in Europe alone, a large portion of which is sold to Africa. Sales to Africa, where some 30% of the used clothing ends up in infamous landfills, because the textiles are too damaged for purchase. An environmental disaster compounded by the fact that the African used-clothing market, called the Mitumba market, also contributes to strangling local textile production, as no one can compete with used-clothing prices (Textile Mountain, 2020).

Oh, patents! FabBRICK®

 Copyright © Françoise Herrmann

Founded by the French architect Clarisse Merlet, FabBRICK® is a company that upcycles used and/or waste textiles into bricks, in turn used for interior design, decorative cladding, and/or thermal or sound insulation. Textiles, sorted by fiber and/or color palette, are shredded, mixed with a patented adhesive compound, and then compressed into bricks that are dried, prior to being used in various decorative and/or functional applications. FabBRICKS® are a patented invention. The invention is recited in a family of French (FR), European (EP) and World (WO) patents, in particular WO2021078815A1, titled (in English) Recycled textile material (in French, Matériau en textile recyclé). The patent was granted on April 29th 2021, to Clarisse Merlet.

The FabBRICK® invention offers a solution at the intersection of a two-fold problematic situation. First, the use of insulating construction materials that are environmentally polluting, high-energy-consuming, and/or potentially damaging. For example, such polluting materials as synthetic polystyrene insulators have a high energy footprint. Even organic, bio-sourced insulating materials have the disadvantage of being potentially depletable. For example, this is the case for plant wool made from straw, cork, or wood; animal wool harvested from sheep; or mineral wool such as fiberglass. Secondly, and most importantly, the invention seeks to offer a new outlet for recycling existing environmental waste, in particular used, and or waste textiles*. Especially considering that no prior art exists for upcycling used and/or waste textiles for construction, specifically for insulation purposes, whether thermal or acoustic. 

Finally, by bringing together concerns about existing insulation material pollution with a high energy footprint , on the one hand, and limited recycling outlets for used textile waste, on the other, the FabBRICK® invention also seeks to offer a product that is aesthetically pleasing. Thus, both the FabBRICK®  product and manufacturing process address problems of the prior art by upcycling used and/or waste textiles into construction and/or insulation materials, using non-polluting, organic adhesive and a press with a zero-energy-consuming footprint. 

The patent Figure 1 below depicts a construction FabBRICK® 10, made of a substance 1, comprising a used and/or waste textile-based stiffening component 2, and an animal and/or plant-based adhesive matrix component 3. The patent Figures 2A and 2B depict, respectively, top (10A) and bottom (10B) views of the FabBRICK® 10. The top view 10A depicts the FabBRICK® 10 tenons 11. The bottom view 10B depicts the FabBRICK® 10 mortises 12.

The patent Figure 3 below depicts the FabBRICK® fabrication press 200**. The press 200 comprises four or more vertical molds 210, attached to a frame 201 and platform 202, and into which the FabBRICK® substance 1 is poured. Each of the molds have lateral sides 211, top 212 and bottom 213 ends. The bottom ends 213 each have a base 214 that translates under compression within the lateral sides 211. Each of the mold bases 214 is also pierced to enable all excess liquid adhesive to drain from the highly absorbent bricks, under compression forces. Excess drainage liquid is then recovered beneath the press in a collection tray, and used to dilute subsequent batches of adhesive.  

The press has a double vertical compression and ejection mechanism, one at the top 220, and one at the bottom 230, each comprising a 20-ton hydraulic cylinder, a stamping hydraulic cylinder 221 at the top, and an ejection hydraulic cylinder 231 at the bottom. Thus, the press 200 exerts downward vertical compression forces on the product inside the molds 210, via a compression stamp 222, and upward ejection pressure 232 that strips the compressed bricks from the molds after a 30-minute pause. A pause designed to enable the compressed bricks to settle into their shapes with sharper edges and augmented density. Compression and ejection forces are exerted via an actuating mechanism 240, equipped with a leverage arm 241.

In the short, subtitled YouTube video below, the FabBRICK® inventor and CEO, Clarisse Merlet, presents the manufacturing process, the advantages, and rationale of her invention.  


Note
* A problematic situation that has been quantified as a 4 to 5.8-million-ton surplus of used clothing, and/or waste textiles, discarded each year in Europe alone (European Environmental Agency, 2024).
**A manual version of the press is described in the patent, with the specification that an automated version would clearly still fall within the scope of the invention.

Mitumba* - A story of used clothing.

 Copyright © Fançoise Herrmann


The documentary, Textile Mountain, produced by Make Europe sustainable for all** shows the impact of the 4 million-ton surplus of used clothing in the world. 70% of which is sold in bales to sub-Saharan Africa. 50% of which is in such a bad state, it ends up in dumps on riverside beds, the sides of roads, or in large fields, such as the well-known, 30-acre, ‘Dandora Dumpsite’ (mountain), on the outskirts of Nairobi (in Kenya).  

The remaining ‘re-usable’ mitumba that floods African markets also ends up canceling all local textile production, since no one can compete with the price or quantity of mitumba. In response to this situation, the documentary highlights two exemplary European solutions to textile waste.  
  • ISATIÓ,  a company that uses the principles of a circular economy to upcycle fabric samples into high-quality fashion products, in Brussels, Belgium.
  • Nuw Wardrobe, a fashion exchange app and social networking community for sharing clothes, in Dublin, Ireland.
As Annie Leonard, founder and author of The Story of Stuff project puts it: There is no such thing as ‘away’. When you throw something away, it must go somewhere.

MESA was designed to increase awareness of roles and responsibilities of EU citizens and policymakers in creating a sustainable future for all. The project began in July 2017, and ended in July 2020.
