Lithoplast is a speculative material and composite developed by Eindhoven-based designer Shahar Livne. Constructed from plastic pieces (which cannot be utilised by the recycling industry), dust, solid residue from coal-mining, and powdery remains from stone masonry, Lithoplast is an easily moldable material.

Lithoplast is the end process that mimics natural metamorphism. Metamorphism is a natural process of the earth where a change in 'the structure or constitution of a rock comes about due to natural agencies, such as pressure and heat, especially when the rock becomes harder and more completely crystalline.' Materials familiar to us such as marble, slate, and quartzite are among the many rocks created through metamorphism.

In mimicking this thousand-year-old process, and arriving successfully at a glossy, rock-like material, Shahar triggers several questions: the first being–what can we consider natural and man-made today? and the second–If materials of functionality and beauty can emerge from the most toxic of our waste, can consider them ‘bad'?

Lithoplast aims to shift the attitude to undervalued waste, and Shahar points to a future where today’s plastic waste will be mined, quite like precious minerals are today.
