Algae Plastic
Algae-based alternative to single-use plastic packaging.
According to the designer, the material only includes natural matter, including the dyes used to colour it, which are extracted from the skins of fruits and vegetable such as blueberries, purple cabbage, beetroot and carrot. The basic mixture is made up of a polymer, a plasticiser and an additive, with the amounts of each ingredient varying depending on the desired consistency of the final product. The polymer and main ingredient in this case is agar – a jelly-like polysaccharide substance that is extracted from red algae by boiling. Talep adds water as a plasticiser and natural dyes to add gentle colour. To make a material that bears a close resemblance to thin plastic, Talep boils the agar mixture to around 80 degrees celsius, before transferring the molten liquid onto a mould.
