Layered containment features

A layered containment comprising:

• an outer structural layer defining a containment cavity and constructed of an organic or organic-based material;
• an interior nanomaterial layer constructed of at least one of the following:
• silicon dioxide, zinc oxide, and/or a nanomaterial of hydrophobic nanoparticles;
• and,
• a central carrier layer underlying the outer structural layer and constructed of a biopolymer,
• wherein the outer structural layer comprises a plurality of parts adhered by the central carrier layer and/or the interior nanomaterial layer without an additional adhesive and wherein the central carrier layer and/or the interior nanomaterial layer extend from a cavity of the containment to cover a portion or the entire exterior surface of the layered containment;
• and
• wherein the biopolymer comprises polyhydroxyalkanoate, lignin, or a mixture thereof.
