Compostable seaweed-based thin films, and associated systems and methods are disclosed herein. In some embodiments, an exemplary seaweed-based thin film comprises a seaweed-based composition comprising agar, alginate, carrageenan, semi-refined seaweed, and/or unprocessed seaweed; an agent comprising glycerin, sorbitol, sodium lignosulphonate, potassium lignosulphonate, calcium lignosulphonate, ammonium lignosulphonate, lignosulphonate, citric acid, ascorbic acid, ethylene glycol, polyethylene glycol, polyglyceride fatty acid esters, guar gum, tributyl citrate, and/or propylene glycol; and water. The seaweed-based composition can comprise 50-90 wt % of the seaweed-based thin film, the agent can comprise no more than 40 wt % of the seaweed-based thin film, and the water can comprise 0.1-50 wt % of the seaweed-based thin film.

An artificial flower, plant, or other botanical is produced from an aqueous agar-based solidifying mixture. The artificial botanical may be colored as desired by adding one or more colorants. The artificial botanical may also be scented by adding a perfume, odorant, or other scent. Because the artificial botanical is produced using the aqueous agar-based solidifying mixture, no animal-based gelatin products are used. The artificial botanical may thus also be edible and satisfies vegan diets. The artificial botanical may thus also be flavored by adding a flavoring, such as fruit, concentrate, or sweetener. The artificial botanical may be all-natural and edible by adding mica powder as the colorant and by adding glycerin as the flavoring.
