#StudioIntegrativeDesign #Master-Thesis

Plastics have shaped our society since the 1950s and will outlive our age as sediments. These man-made materials still allow freedom of design and industrial mass production. However, the global problem of the resulting waste disposal has long since ceased to be compatible with an idea of untouched nature that is to be protected as a refuge from human activities. «lac» researches plant-based plastics in textile applications and their potential as durable and biodegradable alternatives.

The title of this masterthesis is lac and frames the topic of this work. For on the one hand, lac denotes a milky liquid originating from a mammal or plant (Latin), and on the other hand lake (French). Using milk as the raw material, a material was produced at the beginning of the nineteenth century that became known as galalith. This material served as a cheap substitute for animal raw materials such as ivory, horn or tortoiseshell and was one of the first plastics.

Experimenting with plant based plastics, this masterthesis aimes to offer solutions for synthetic fiber textiles, that are non- fossil based and biodegradable. With polylactic acid fibres, that derive from starch, in combination with swiss grown flax fibres an archive developes.

Plastics are not only trash, that destroys our dream of perfect nature, it also comes from this nature and can get integrated into environment in other ways than trash.
