Abstract

Accompanying the accumulation of plastic waste is the growing demand for reusable and biodegradable alternatives. In addition, many commercial water filters consist of a plastic outer shell and replacement of these filters contribute to the progress of plastic pollution. Not only does plastic in the environment negatively and physically impact wildlife, additives of the plastic, including phthalates, can leach into waterways and end up in tap or drinking water. As contaminants in water pose a risk to wildlife and human health, more efficient and environmentally friendly alternatives must be considered. To combat these waste related issues, a 3D-printed water filter is proposed here. The structure of this filter is comprised of polylactic acid (PLA), which is a biodegradable polyester and is comparable in strength and toughness to petroleum-based plastics. A composite mixture of graphene oxide and nanocellulose is added to the inside of the PLA cartridge, supplying its filtration properties. These materials allow the refinement of commercial water filters into a device that is biodegradable, cost-effective, and environmentally friendly. The purpose of this study is to find an alternative method to commercially purify water and reduce the growth of plastic waste in the environment.
