## Abstract

An insulated container may include a rigid container surrounding an insulation layer formed from a post-industrial, pre-consumer card waste. The insulation layer may be characterized by a lack of any wrapping material. The insulation layer may be manufactured using a variety of converting processes including, carding, airlay, and needle punch to form a non-woven material for providing consistent density throughout the insulation layer. The insulation layer may include a natural fiber lamination layer on an outer surface of the insulation layer. The insulation layer may be biodegradable in an anaerobic environment.

## Claims

### Claim 1

A method of making an insulated container comprising the steps of:
providing a rigid container;
providing a quantity of post-industrial, pre-consumer cotton waste;
processing the post-industrial cotton waste into a sheet;
converting the waste via one or more converting processes including: carding, airlay, and needle punch to achieve a specified thickness and density;
laminating a natural fiber lamination layer, comprising only a single layer, to the sheet cutting the sheet into rectangular sections;
forming the rectangular sections into interlocking C-shaped members; and
placing the interlocking C-shaped into the rigid container.

### Claim 2 (depends on 1)

The method of claim 1 wherein the cotton waste includes cotton waste generated from one or more of cotton processing, cotton manufacturing, and/or cotton converting.

### Claim 3 (depends on 1)

The method of claim 1 wherein the insulation layer is capable of maintaining a constant internal temperature for 48 hours where three 500 ML and two 250 ML IV bags are cooled by four 24 oz frozen ice packs placed at the top and bottom below a payload.

### Claim 4 (depends on 1)

The method of claim 1 wherein the insulation layer is biodegradable in an anaerobic environment.
