The solution consists of a pulp fiber cup and lining which innovates upon the existing fiber cup and plastic lining by using raw materials and a manufacturing process that results in a fully biodegradable product that maximizes recoverability. The cup can be made with the same raw materials as current fiber coffee cups (minus the plastic lining), but the design of the cup is new- it features a perforated lip at the top that when ripped, flattens the cup to accelerate the biodegrading process. The clear lining of the cup, which is suitable for use with hot and cold liquids, is composed of a combination of seaweed and x. This lining, which is adhered to the cup through a proprietary process, is an excellent sealant material. Tests demonstrate that boiling water at 212 degrees F can be poured into the cup, left to cool and remain for 10 days without any leakage. This same cup can be used again with boiling water with no significant sealant expansion. No fungus or mold was observed and no change of color occurred in the liner in this time period. The estimated time it takes for this solution to fully biodegrade is approximately one year. 1 encouraging fact is that there is no fungus and mold buildup observed;no change of color of the sealant/liner. the application of sealing and drying is pivotal. All ingredients are approved for human consumption and affordable to produce.
