Bio Filter : bioplastic + activated charcoal

 

In 1831, Mr. Touery, a professor at the French Academy of Medicine, drank strychnine, a deadly poison, in front of all his colleagues. He survived. How ? He had combined the lethal dose with activated charcoal. “That’s how powerful activated charcoal is as an emergency decontaminant in the gastrointestinal (GI) tract, which includes the stomach and intestines. Activated charcoal is considered to be the most effective single agent available. It is used after a person swallows or absorbs almost any toxic drug or chemical.”*

Last year Fab Textiles worked on a flexible bio filter design to reduce the pollution of Monterrey, the most polluted city in Mexico. This research was undertaken for an architecture project named Restology, a multidisciplinary project between architects, interior designers, product designers, fashion designers, material designers, graphic designers, electronic engineers and marketing strategists. During one month, Maria Luisa and I collaborated at Fab Textiles, Fab Lab Barcelona on the development of a bio-composite made of bioplastic mix with activated charcoal.

Activated charcoal is one material that seems especially applicable to Fab Lab makers, because of its ecologically sound and purifying properties. It is essentially a form of incredibly microporous carbon, processed from natural carbon-rich materials by applying various gases or chemicals to ‘burn’ in tiny holes and thus exponentially increasing its surface area. The result ? A material that can efficiently filter out all manner of impurities and toxins. A super-sponge, if you will. Bioplastics present themselves as an excellent and similarly sustainable substrate for activated charcoal with a wide range of uses.

During the material research, Maria Luisa and I tried out 10 different recipes to discover the correct ratio of ingredients that provided the most appropriate amount of flexibility for using activated charcoal as a filter. For this research, we decided to use gelatin as our biopolymer and glycerol as our plasticizer. By experimenting with the quantities of glycerol relative to activated charcoal, one can influence the degree of flexibility of the mixture. Maria Luisa told me that in the previous experiments  with her team, the issue was that the samples were cracking  after the drying process. Probably because the bioplastic mixture was containing too much activated charcoal according to the glycerol ratio.

At the end of the experiments, we succeeded to have good results, with samples with different flexibility (hard like a rock to flexible like rubber) and textures (Rough to Smooth and Matte to Shiny). I noticed that some of the samples were conductive, an interesting fact that we could use for future e-textiles and wearables.

Some samples made for the Restology project were sent to the laboratory to be tested. The scan of electrons viewed in the microscope shows that the best recipe for creating a bio filter is one with the greatest amount of activated charcoal and almost as much glycerol as gelatin for better flexibility. The amount of ingredients use for this recipe is 20% glycerol , 28% gelatin, 57% activated charcoal and 14% water. Compared to the others, this recipe presented the highest average pore-size of 50μm, “creating a set of thin porous walls one behind another with inside cavities allowing the filtration of air pollutants.”**

The laboratory analysis proved that one of the activated charcoal and bioplastic mixture was porous enough to fix pollutant particles. To validate the filtering potential of this bio-composite, the Restology researchers developed a machine measuring microparticles and gases such as NH3, Nox, Alcohol, Benzen, Smoke, CO2… This two-chambered device contains an Arduino system connected to two sensors : one reading dust density (GP2Y1010AU0F sensor) and one calculating air quality (MQ135 sensor). The two chambers are separated by the bio-composite filter, the polluted air is introduced in the first chamber, measured, and then remeasured in the second chamber after passing through the bio filter.

BioBags collection

“Today, my driving motivation is to discover methods, materials that are ethically sound and sustainable.” Clara Davis

This BioBags collection, created by Clara Davis from the FabTextiles at Fab Lab Barcelona, is an environmental project about how to replace plastic bags and daily life packaging with biodegradable materials. A plastic bag takes about 450 years to disintegrate in nature. Those three BioBags, made with gelatin base bioplastic are completely biodegradable. It takes about one week to dissolve completely in the water.

Gelatin base bioplastic is a recipe with 100% natural ingredients : 78% of water, 16% of gelatin and 6% of glycerol. With this recipe you can cook a strong material. The difference between gelatin bioplastic and petroleum plastic is that bioplastic is not long-term resistant to heat (more than 40°) and water (more than one week). That’s why it’s so easy to recycle it.

For now the problem is still the price of creation, too high to considerate the BioBags collection just like simple packaging. It’s costing approximately 80 euros to create one BioBag : price of material, design, machine and time of work. You should know that gelatin base bioplastic takes about one week to dry. A long cooking process before starting to laser cut the BioBag.

The BioBag collection stay at the moment a project between Art & Design but with financial investment we can easily imagine a biodegradable industry coming in a near future.

Barcelona Maker Faire 2017

barcelona maker faire 2017

This year the team FabTextiles (Fab Lab Barcelona) of Anastasia Pistofidou and Clara Davis participated to the Maker Faire Barcelona 2017.

Maybe you are wondering what is a MakerFaire ? A Maker Faire is a world event gathering makers : creators, innovative craftsmans, inventors and engineers. This Maker Movement is about using technology, creating new ways to produce together, learning how to do it yourself for changing our industry. The first Maker Faire was established by Dale Dougherty, one of the creators of Make Magazine, in San Mateo, California, in 2006. The goal is to introduce to the people the latest inventions and innovations, to teach them how to do it themselves with workshops, to discuss with them about different topics and to allow makers to meet each other and share their knowledge.

“ECOcyborg” YoMo festival 2017

ECOcyborg is a fashion tech show created by Alex-Murray Leslie and the students of the IED (Istituto Europeo di Design) Barcelona. This artistic performance is about the impact of technologies in our way of creating, producing and consuming today. The show took place in the Youth Mobile Festival (YoMo) during the Mobile World Congress 2017 (27 February – 2 March) in Barcelona.

During the last two months, the team of FabTextiles collaborated on this project by designing and producing materials used for making the garments of the show : bioplastics, 3d printed fabrics, thermoformed acrylic masks, laser cut textiles, weaving with electroluminescent threads…alex murray leslie yomo Alex-Murray Leslie (founder of Chicks on Speed, an internationally renowned art band) during the performance “ECOcyborg” at the YoMo Festival 2017.

  • 3D PRINTED FABRICS : USING SOFTWARE AND 3D PRINT MACHINE FOR CREATING GARMENTS

Anastasia Pistofidou design on the software Rhinoceros and Grasshopper a chain for printing in 3D.  The 3D printed chain like textile allows to print a pattern made of small rigid volumes that assembled together becomes a flexible material. The students from IED Barcelona took the chain for making the coating of a dress.3D print fabrics 3D print fashion tech show

  • THERMOFORMED ACRYLIC : It’s possible to deform an acrylic sheet by heating it up to 160degrees and using a vacuum forming machine. You can give to the acrylic sheet the shape you want by using a mold. For creating those thermoformed acrylic masks Anastasia Pistofidou 3Dmodel a human face made in MakeHuman software. The next step is to CNC mill the piece of PU high density foam (can be negative or positive. After, the 2d pattern is laser cut on an acrylic sheet of 3mm and finally heated-up and placed it on the foam face and put it under the vacuum forming machine. 3C2A3092mask thermo fashion tech show
  • WOVEN ELECTROLUMINESCENT THREADS : During the last day of the Textile Bootcamp Academy, a group mentored by Alex-Murray Leslie developed a woven piece that embedded Corning Fibrance Light-Diffusing Fibers from Versalume, reflective textiles and recycling elements like plastics bags and packaging papers. The loom used for creating the weaving was laser cut and built in the Fab lab from an open source file found in instructubles. The final woven piece became a shoulder piece inside a laser cut petticoat.
