Abstract
A method and apparatus for converting expended thermo-plastic material, specifically empty plastic bottles, into artificial rocks, by placing the empty thermoplastic bottle in the apparatus between two sliding carriages, on each of which a rock has been mounted; and each carriage attatched to a hydraulic jack, which, when the handle is pumped, moves the carriage toward the bottle which has been heated to malleability by heat lamps mounted above and sideways to the bottle, and the said heated, flexible bottle is squeezed between the two rocks mounted on the carriages, and then the bottle is rotated and the process repeated to give the bottle a rock shape. The rock shape may be further altered using a portable heat gun.
Claims4
A method of converting an expended thermoplastic container by:
- (a) heating the container to a temperature where it becomes malleable,
- (b) pressing the malleable container between two real rocks to give it a rock shape,
- (c) spraying the rock shaped container with a bonding agent, then a texturing agent, then a concrete staining agent to form an artificial plastic rock,
- (d) attatching the artificial plastic rock onto a substrate.
