ABSTRACT:
This invention pertains to foamed and solid algal plastics and products made therefrom, and methods for making algal plastics. The invention also pertains to algal plastic resin precursors for generating the foamed and solid algal plastics and algal plastic products. The foamed algal plastics comprise a foamed and stabilized filamentous algal fiber matrix having substantial dimensional stability. The foamed algal plastics can be used, for instance, to generate packing materials, such as molded packings or foamed particles packings (e.g. packing peanuts). The solid algal plastics comprise a stabilized filamentous algal fiber matrix having substantial dimensional stability. They can be formed from any plastic forming process, such as molding, extrusion, calendering, casting and thermoforming and can be used to make a wide variety of solid plastics, such as, for example, films, rods, tubes, sheets, containers, and shaped forms, such as golf tees. The invention also pertains to cements comprising a stabilized filamentous algal fiber matrix having substantial water retentive capability.
