Decoding Labels: A Scientific Guide to Sustainable Packaging

What each label actually means

• ★Recyclable: Could be recycled if it is one clean, sortable material — not a promise that this object will be.
• ★Biodegradable: Will break down eventually — even a plastic bottle counts, on a ~450-year clock, as microplastics rather than soil.
• ★Compostable: Breaks down under specific heat and microbes. If it doesn’t say Home Compostable, assume it needs a factory you may not have.
• ★Vegan: Certifies zero animal ingredients. Silent on packaging waste.
• ★Bioplastic: Derived from plants. Still structured like plastic.
• ★Plant-based: Bio-based carbon content. Same synthetic polymer backbone.
