Are cellulose sponges safer than plastic ones?
Based on 1 peer-reviewed studykitchen
Verdict: Safer
Yes. Cellulose is plant fiber. It doesn't shed plastic and biodegrades when worn out.
What's actually in it
Cellulose sponges are made from wood pulp, naturally absorbent, and biodegradable. No plastic, no microfiber shedding. Some cellulose sponges have a thin non-plastic abrasive layer.
What the research says
A 2025 study in Sci Adv shows how much microplastics move through the body. Kitchen sources add up. Cellulose is among the cleanest swap-outs.
Replace cellulose sponges every few weeks, sanitize by microwaving wet for 1 minute, and compost when done.
