(11) FIG. 1 illustrates a top down view of a coffee cup insulator sleeve according to the present disclosure.

(12) Referring to FIG. 1, an insulator sleeve 100 for holding a cup, such as the disposable paper or plastic cup, containing a hot beverage is formed of a biodegradable coffee ground amalgam 103. The insulator sleeve 100 is formed such that the insulator sleeve 100 has an outer surface 105 and an inner surface 107. The outer surface 105 is grasped by an individual drinking a hot beverage from a disposable paper or plastic cup. The inner surface 107 receives the disposable paper or plastic cup inserted therein.

(13) The insulator sleeve 100 is formed of a biodegradable coffee ground amalgam produced by mixing coffee grounds optionally with the residue of the husking process (i.e., coffee silver film). This amalgam is compacted and the resulting compacted material is injected into a mold. To aid in the injection into the mold, the compacted material is maintained at 70% humidity. While the insulator sleeve 100 is shown, it will be understood that other objects, such as tray, tray covers, coasters and the like may be produced from this process.

(14) The compacted material (i.e., coffee grounds, coffee silver film, plastic cups, plastic containers, cardboard cups, and/or cardboard containers for food) is inoculated with mycelium of any of a variety of species of mushrooms. The resulting molded coffee ground amalgam incubates at a temperature of 25 C. (i.e., 77 Fahrenheit) for a period of eight days. After the incubation period, the molded coffee ground amalgam is heated to a temperature of 55-66 C. to remove any humidity from the resulting product. Any of the many cafeteria residues, such as plastic cups, plastic containers, cardboard cups, and cardboard containers for food may be mixed with one or both of the other residues, coffee grounds and or coffee silver film.

(15) The resulting insulator sleeve 100 is then polished to provide a shiny appearance and submerged in yucca starch and dried.

(16) FIG. 2 illustrates a side view of a coffee cup insulator sleeve according to the present disclosure.

(17) Referring to FIG. 2, the insulator sleeve 100 is oriented vertically with a top surface 109 and a bottom surface 111. It will be understood that the top surface 109 of the insulator sleeve 100 receives the disposable paper or plastic cup while the bottom surface 111 restrains the disposable paper or plastic cup from passing beyond the point where the diameter of the disposable paper or plastic cup equals the diameter of the bottom surface 111. Alternatively, or mutually, the top surface 109 or the inner surface 107 as in FIG. 1 provide the same function of arresting the disposable paper or plastic cup from passing beyond the point where the diameter of the disposable paper or plastic cup equals the diameter of the top surface 109 or the inner surface 107 of the insulator sleeve 100.

(18) FIG. 3 illustrates a side view of a disposable cup with a coffee cup insulator sleeve according to the present disclosure.

(19) Referring to FIG. 3, a disposable cup 321 is inserted into the insulator sleeve 100. As discussed above, the inner surface 107, as in FIG. 1, restrains the disposable cup 321 from passing beyond a point where the diameter of the inner surface 107 equals the diameter of disposable cup 321. Once the disposable cup 321 is restrained from passing beyond that point, friction keeps the insulator sleeve 100 from sliding down the outer surface of the disposable cup 321. While the terms disposable cup 321 is used herein, any type of cup may be used provided a mold corresponding to the cup is available from producing the insulator sleeve 100.

(20) FIG. 4A illustrates of a side view of a coffee cup tray according to the present disclosure.

(21) FIG. 4B illustrates of a bottom view of a tray according to the present disclosure.

(22) Referring to FIGS. 4A and 4B, a tray formed of a biodegradable coffee ground amalgam produced by mixing coffee grounds optionally with the residue of the husking process (i.e., coffee silver film). This amalgam is compacted and the resulting compacted material is injected into a mold. The compacted material is inoculated with mycelium of any of a variety of species of mushrooms. The resulting molded coffee ground amalgam is incubated for a given time period. After the incubation period, the molded coffee ground amalgam is heated to remove any humidity from the resulting product. The resulting tray is then polished to provide a shiny appearance and submerged in yucca starch and dried.

(23) While FIG. 1 provides an insulator sleeve 100 and FIGS. 4A and 4B provides a tray, it will be apparent to those skilled in the art that any product capable of being molded may replace the insulator sleeve 100 and tray 401.
