Abstract
In general, this disclosure relates to an apparatus that compresses lightweight plastic waste (e.g., used grocery bags, empty trash bags, food wrappers, etc.), and then applies a limited amount of heat to “bake” the compressed plastic into a “brick” of plastic. The plastic is compressed, and then heated enough to cause it to retain its compressed shape, without melting or substantial outgassing.
Claims20
A plastic densifier comprising:
- a body, at least partially enclosing an interior volume with an aluminum interior surface;
- a loading port in the body, configured to allow plastic to be loaded into the body;
- a lift within the body and configured to reduce the interior volume when actuated, compressing plastic within the interior volume;
- and
- a heating element positioned beneath and abutting the aluminum surface, the heating element configured to heat the plastic within the body to a temperature in a range of 100 C to 180 C.

A method for densifying plastic, the method comprising:
- loading plastic to be densified in a compression chamber;
- compressing the plastic;
- and
- applying heat to the plastic to achieve a temperature in a range of 100 C to 180 C, wherein the compression and the heat bake the plastic into a brick.
