## Abstract

A disposal system for the processing of solid waste devices to recycle materials located within the devices and recover, reuse and recycle such materials. Such system may include a primary chamber and secondary chamber, attached preferably by use of one or more exhaust ducts, and a secondary chamber exhaust duct. The solid waste devices may include any type of waste, such as electronics waste, medical device waste, and the like.

## Claims

### Claim 1

A waste processing system, comprising:
a primary chamber section; and
a secondary chamber section connected to the primary chamber section via an exhaust duct,
wherein the primary chamber section comprises
a heating chamber,
a primary chamber disposed within the heating chamber, the primary chamber being configured to receive feedstock, and
a burner configured to heat the heating chamber and the primary chamber, and
wherein the secondary chamber section comprises
a secondary chamber, and
a secondary chamber exhaust duct connected to the secondary chamber.

### Claim 2 (depends on 1)

The waste processing system according to claim 1, wherein the primary chamber is loaded with an inert gas.

### Claim 3 (depends on 1)

The waste processing system according to claim 1, wherein the primary chamber section further comprises a lid that is configured to collect syngas produced while heating the heating chamber and the primary chamber.

### Claim 4 (depends on 1)

The waste processing system according to claim 1, wherein the primary chamber section further comprises a cooling fan configured to cool the heating chamber.

### Claim 5 (depends on 1)

The waste processing system according to claim 1,
wherein the primary chamber comprises a plurality of heat transfer fins that are configured to transfer heat from the primary chamber to the heating chamber, and
wherein the plurality of heat transfer fins are attached to an exterior surface of the primary chamber.

### Claim 6 (depends on 5)

The waste processing system according to claim 5, wherein the plurality of heat transfer fins are made of the same material as the primary chamber.

### Claim 7 (depends on 1)

The waste processing system according to claim 1,
wherein the primary chamber section further comprises a drive motor configured to rotate the primary chamber, and
wherein the drive motor is attached to a bottom surface of the primary chamber and the heating chamber.

### Claim 8 (depends on 1)

The waste processing system according to claim 1, wherein the feedstock comprises computer or electrical equipment, or medical waste items.

### Claim 9 (depends on 1)

The waste processing system according to claim 1, wherein the secondary chamber section further comprises a syngas combustion air fan configured to supply combustion air to the secondary chamber.

### Claim 10 (depends on 9)

The waste processing system according to claim 9, wherein the secondary chamber section further comprises a syngas combustion air diffuser connected to the syngas combustion air fan and the secondary chamber exhaust duct.
