All toilet tissue is biodegradable.

charmin is somewhat biodegradable. if anything i would suggest Royale because is does brake down the best. i did i science fair project and i used 5 different kinds of toilet paper. Charmin Ultra Strong. Charmin Ultra Soft. Royale. Cottonelle Comfort care and Swan school bran. so i would suggest royale or swan school bran.
