Compostable cold cups are typically made from a variety of biodegradable and compostable materials. Common materials used in their production include:

PLA (Polylactic Acid): PLA is a bioplastic made from fermented plant sugars, usually derived from corn or sugarcane. It is one of the most common materials used in compostable cold cups. PLA is both biodegradable and compostable under the right conditions.

Bagasse: Bagasse is a byproduct of sugarcane processing. It is a fibrous material that is often used to make compostable cups. Bagasse cups are sturdy and can handle both hot and cold beverages.

Ingeo: Ingeo is a biopolymer made from fermented plant sugars, similar to PLA. It is commonly used in the production of compostable plastics, including cold cups.

PBAT (Polybutylene Adipate Terephthalate): PBAT is a biodegradable and compostable polymer often used in conjunction with other materials to enhance flexibility and durability.

Starch-Based Plastics: Some compostable cold cups are made from starch-based plastics, which can be derived from corn, potatoes, or other starch-rich crops. These materials are biodegradable and compostable.

Paperboard with PLA lining: Some compostable cold cups combine a paperboard exterior with a PLA (polylactic acid) or similar bioplastic lining. This combination provides a balance between the renewable aspect of paper and the protective qualities of the bioplastic lining.

Cornstarch: Cornstarch-based bioplastics are used in the production of some compostable cold cups. These plastics are derived from corn and are biodegradable and compostable.

Wheat Straw: Wheat straw is an agricultural byproduct that can be used to make compostable cups. It is often utilized as a fiber reinforcement in combination with other biodegradable materials.
