PLA Cups Manufacturer - ShinHigh Bio

Compostable Cold Cups

Compostable cold cups (suitable for beverages under 122°F/50°C) are crafted from polylactic acid (PLA), a non-GMO corn-derived biopolymer. These PLA cups meet the strictest international standards for biodegradability and compostability, holding ASTM D6400 certification for “compostable plastics.” They look the same as conventional plastic cups, in terms of appearance, weight and durability. However, when composted, they break down completely into water, CO₂ and organic matter. Unlike petroleum-based plastics—which create toxicity and persist in ecosystems—these cups originate from renewable resources, significantly reducing environmental impact.

FAQ about Compostable Plastic Cups

What does the "Compostable" logo on the cups indicate?

The "Compostable" logo printed on cups serves as a visual guide for municipal recycling and composting facilities. It ensures proper sorting during waste processing, streamlining the cup's journey to industrial composters where it can break down efficiently. This reduces contamination risks and supports closed-loop waste management systems.

How long does it take for these cups to decompose?

Decomposition time varies by composting method: Commercial composting facilities: Full breakdown occurs within 180 days due to controlled heat, moisture, and microbial activity. Home composting systems: May take 1-2 years, depending on factors like temperature, aeration, and material turnover efficiency.

What environmental benefits do compostable cups offer?

These cups provide dual sustainability advantages: Carbon-neutral cycle: Made from plant-based PLA, their production uses 65% less fossil fuel than conventional plastics. Additionally, plants absorb CO₂ during growth, enhancing carbon sequestration. Waste reduction: They eliminate plastic pollution risks—no microplastics enter ecosystems, and unlike traditional plastics, they don’t persist in landfills for centuries.
