Agar plasticity is an ongoing material research project, in which the designers are exploring the potential usefulness of agar as one of alternatives to synthetic plastics. Its raw material is seaweed - precisely, two kinds of red algae, which grow and is harvested worldwide, and agar can be extracted by boiling the red algae. It is sold in dried state in shapes of block, flake and powder. Block agar shows porous, feathery structure and is very light despite its volume. These feautures led to explore its possibility as packaging material. The designers have worked on three different material experiments. Firstly, pure agar powder by itself. Secondly, combining agar powder with extracted red algae fibre. Thirdly, by mixing agar powder with shell ash, which is also a waste product from the food industry.
