A university student has gone from stool to stools after transforming cow manure into a range of designer household furniture. Sanelisiwe Mafa, a Product Design Student at Birmingham City University, came up with the innovative idea in a bid to create useful items from the waste material.After researching how cow manure could be used as a sustainable resource she put her ideas into practice and transformed the manure into a material which could be shaped, moulded and styled into different items of furniture.She experimented with the substance before finding a method which allowed the manure to be manipulated into a range of shapes and sizes while retaining the detail of the material.The manure has been used to produce a range of stools and designer flower pots, mounted on wood stands, which are also fully recyclable.
