Abstract
The present invention provides methods for preparing the nut waste pot composites from a nut waste component, one or more binders, and an oil.
Claims16
A cured nut waste pot composite prepared by the following method comprising the following steps:
- (a) providing a nut waste component selected from the group consisting of nut shells, nut hulls, and a combination of nut shells and nut hulls;
- (b) drying the nut waste component or adjusting the nut waste component to a pH of 5.0 to 8.0 then drying, sterilizing, or torrefying the nut waste component;
- (c) cooling the dried or pH adjusted then dried, sterilized, or torrefied nut waste component to room temperature;
- (d) grinding the nut waste component to a size less than 250 μm;
- (e) contacting the nut waste component from step (c);
- one or more binders selected from a group consisting of polyhydroxybutyrate (PHB), polyhydroxyalkanoate (PHA), polyhydroxybutyrate (PHB), polylactic acid (PLA), guayule, natural latex, bentonite, an anionic starch, hyaluronic acid, and any combinations thereof;
- and an oil producing a mixture;
- (f) heating the mixture to a temperature from about 150° C. to about 320° C. for about 15 minutes;
- (g) extruding, molding, or thermoforming the heated mixture from step (f) into a pot form;
- and
- (h) cooling the pot form to form the cured nut waste pot composite;
- wherein the mixture in Step (c) consists of 65 to 99.9 wt %;
- of the nut waste component, 0.1 to 35 wt % of one or more binders, and 0.0 to 20.0 wt % of an oil;
- and
- wherein the method further comprises step (i) by adding additional at least one fungus, at least one bacterium, or a combination of at least one fungus and at least one bacterium.
