Some might find it problematic to use resources that requires killing an animal because of religious or animal welfare beliefs. Arguments are also made that as long as there's a meat industry, it is better to use product from the entire animal, including skin and bones. Some might consider gelatin to be a product that comes from a waste stream, but this is considered controversial by others. -Acrylic is a petrol based plastic but results in very shiny foils and sheets and can be reused endlessly for casting high quality bioplastic sheets. +Acrylic (for the mold) is a petrol based plastic but results in very shiny foils and sheets and can be reused endlessly for casting high quality bioplastic sheets. +Using plant-based ingredients is not by definition petrol-free. Imagine they have to travel long distances by plane, boat or truck: it takes fuel. Also, the effects of GMO technologies and pesticides can be harmful to the environment and it's worth using knowing the source and production standards involved. If you can afford it, buying organic ingredients is a good starting point. ### Sustainability tags @@ -192,6 +195,8 @@ The biofoam feels like the foam-like packaging materials sometimes used for ship - **Chemical resistance:** needs further research - **Scratch resistance:** poor - **Surface friction:** sliding +- **Color modifiers:** none + ### Tactility & sound impression @@ -222,30 +227,28 @@ By Cecilia Raspanti, Textile Lab, Waag Amsterdam, 9 March 2020 ### Estimated cost (consumables) in local currency -0,50 Euros for a yield of approx 150 ml +0,78 Euros for a yield of approx 200 ml ### Local supplier/sourcing info Gelatin powder - Jacob Hooy (online retailers) Glycerine 1.23 - Orphi/Chempropack (online retailers) -Eco dishwasing soap - any (eco)supermarket -Lego sheet - second hand/flea market/thrift shop +Acrylic sheet - Online retailers, DIY stores ## Copyright information ### This recipe is in the public domain (CC0) -No +Yes ### This recipe was previously published by someone else -Yes - -**Biofoam Recipe** by Cecilia Raspanti (Textile Lab, Waag Amsterdam), biofoam sample from the material archive, n.d. +No ##References - **The Secrets of Bioplastic** by Clara Davis (Fabtex, IAAC, Fab Lab Barcelona), 2017, [link](https://issuu.com/nat_arc/docs/the_secrets_of_bioplastic_). - **Glycerin** by Materiom, n.d.
