Purestone Environmental Overview

Purestone is an excellent performer in its intended application.
Purestone 7mm reduces mineral consumption by over 65% per slab as oppoised to standard 20mm e-stone.
The supply of minerals does not interfere with any confined aquifer and is from a recycled resource.
The polymer raw material supplier complies with the relevant environmental legislation.
Waste management procedures divert all waste into recyclable and reusable materials.
Purestone delivers a sustainable solution for implementing the number one measure in the hierarchy of controls in accordance with Australian Commonwealth Government.
Energy consumption is below 20mj/sqm of product.
Dust emission is 0mg/sqm of product.
Styrene emission is below 0mj/sqm of product.
Due to the nature of the polymer very VOC levels of 0 are obtained.
Effluent water is recycled and contain less that 0mg/L of contaminants. (permitted level 40mg/L).
Purestone does not contain and prohibited substances.
Noise level from the production does not exceed 30db(A).

Purestone environmental programs ensure a long product life cycle, whilst minimizing environmental loads and providing a sustainable product and manufacturing process the next generation in

surface technology, unmatched by any company or product in the world.
