Abstract: Apparatus and methods for manufacturing compostable, biodegradable drink straws from polyhydroxyalkanoate (PHA) material are disclosed herein. Such apparatus may include a hopper that contains raw PHA material, an extruder that receives the raw PHA material from the hopper and produces extruded PHA material, one or more waters baths that cool the extruded PHA material, a puller that pulls a tubular stream of PHA material through the system, and a cutter that is configured to cut the stream of PHA material into finished straws. The finished straws may be soil- and marine-biodegradable, as well as home- and industrial-compostable.

Abstract: A lid for a drinking cup may include a rim portion and a raised cover portion. The rim portion may be adapted to matingly engage an upper peripheral edge of the drinking cup so as to selectively maintain the lid in a covering relationship on the cup. The raised cover portion may extend from the rim portion, and have a perimeter adapted to impede spillage of liquid over a peripheral edge of the lid. Liquid spilled or released on the cover portion or perimeter portion may drain away from the periphery of the cover portion and into the drinking opening or a recess in the cover portion that is adapted to receive a reclosable tab.
Abstract: A food or beverage container may include an open-ended expanded polystyrene (EPS) foam body and a shrink sleeve film label. The shrink sleeve film label may be made of a material which may enable a high quality design to be displayed on the outside of the EPS foam body. A heating source may be applied to the shrink sleeve film label to fit the label to the EPS foam body. The shrink sleeve film label may be affixed to the EPS foam body using an adhesive. The EPS foam body, the shrink sleeve film label, and/or the adhesive may comprise compostable or recyclable materials, such that the entire food or beverage container may be compostable or recyclable.
