Compostable seaweed-based compositions, and associated systems and methods are disclosed herein. In some embodiments, the seaweed-based composition comprises (i) a phycocolloid including agar, alginate, carrageenan, and/or unprocessed seaweed, (ii) a polymer comprising thermoplastic starch (TPS), polycaprolactone (PCL), polylactic acid (PLA), polyhydroxyalkanoates (PHA), polyesteramide (PEA), polybutylene adipate terephthalate (PBAT), polybutylene succinate (PBS), and/or polyvinyl alcohol (PVOH), and (iii) an additive, wherein the phycocolloid comprises no more than 90 wt% of the seaweed-based composition, the biopolymer comprises no more than 80 wt% of the seaweed-based composition, and the additive comprises no more than 50 wt% of the seaweed-based composition.

A buffer material of the present disclosure is a buffer material including cellulose fibers, and a binding material that binds the cellulose fibers, in which the binding material contains starch and natural wax. A method of producing a buffer material of the present disclosure is a method including a defibration step of defibrating a raw material containing cellulose fibers by dry type defibration, a mixing step of mixing the cellulose fibers defibrated in the defibration step with a binding material in a gas phase to obtain a mixture, a molding step of compressing the mixture to form a sheet, and a lamination step of laminating a plurality of the sheets to form a buffer material, in which starch and natural wax are used as the binding material.
