Abstract
A biodegradable cigarette filter has a filter tow surrounded by one or more wrapper layers. The filter tow is a mixture of hemp, a second fibrous material comprising cotton, paper, or a mixture of cotton and paper, and a thickening and bonding agent comprising flour or starch initially added to the mixture as a solution in water. The mixture of hemp and the second fibrous material in the filter tow act as a filtering matrix for the cigarette smoke when consumed by a user. In one example, two wrapper layers comprising a plug wrap and a tipping paper surround the filter tow. The filter tow or one or both wrapper layers, or both the tow and wrapper layers, may contain plantable seeds.
