These straws are made primarily from sugarcane. Sugarcane absorbs carbon dioxide during its growth, so the carbon dioxide emissions from incineration can be considered zero, contributing to a reduction in greenhouse gases compared to conventional polyethylene. They are also recyclable, just like polyethylene. Individually wrapped for hygiene. Stored in a dark place. Please confirm the condition in the photos before purchasing.
