Compostable T-shirt bags are designed to decompose significantly faster than traditional plastic bags. Under industrial composting conditions—where high heat, moisture, and microbial activity are present—these bags typically break down within 90 to 180 days.
Made from renewable plant-based materials like corn starch, PLA (polylactic acid), or PBAT (polybutylene adipate terephthalate), compostable bags are engineered to meet standards such as ASTM D6400 or EN 13432. These certifications ensure that bags disintegrate and biodegrade without leaving harmful microplastics or toxins behind.
It's important to note that compostable bags require specific composting environments to break down efficiently. While they may degrade more slowly in home compost bins or landfill settings, industrial compost facilities can optimize the process and turn the material into usable compost.
For restaurants, cafés, and grocers in regions with access to composting programs, compostable T-shirt bags are an eco-forward alternative that helps reduce landfill waste and support sustainability initiatives.
