Plastic foam aggregate matrix made from recycled paper and fiber products
First Claim
1. A plastic foam material comprising:
- an aggregate of discrete parts made of substantially individual cellulose fibers combined with a cellulose starch and including a plurality of bubbles produced by a gas-generating agent; and
a matrix enveloping said discrete parts, including a plurality of bubbles produced by a gas-generating agent, said matrix retaining the aggregate in a geometric shape.

Abstract
A plastic foam material comprises an aggregate of discrete elements made of substantially individual cellulose fibers combined with a cellulose starch and including a plurality of bubbles produced by a gas-generating agent. The discrete elements are suspended in a matrix also including a plurality of bubbles produced by a gas-generating agent. In a preferred embodiment the matrix is also made of substantially individual cellulose fibers combined with a cellulose starch and formed into a geometric shape. In another preferred embodiment the discrete aggregate elements are substantially closed-cell foam and the matrix is substantially open-cell foam. In yet another preferred embodiment the discrete aggregate elements are substantially closed-cell, and the foam matrix is also substantially closed-cell.
