Cardboard pulp

Cardboard pulp

Pulp it!

Paper is probably the most common and easy material to find in the streets. Under the shape of cardboard, napkins, flyers, and so on, its main use is to carry a product, service or information for a short moment. After having fulfilled its role, it often becomes waste, filling trash bins and containers, before being recycled or burned.

Using cardboard or paper as the main material and sticky rice flour as the glue it is possible to create a very sticky clay, which once dry, become strong. This material is easy to mould, asks little energy to make, uses no chemicals or dangerous tools and is cheap. The clay can be moulded as plastic and even replace it when the object doesn't need to be in contact with water. The time of drying can last from a few days to a few weeks depending on the size of the objects, the temperature, the moisture in the air etc.
The project aims to create and share technics and recipes online in order to encourage the personal creation of objects.
