Other proteins work as well meaning the process can be scaled without interfering with food supplies.

Researchers at Princeton Engineering have found that egg whites can be used to cheaply remove salt and microplastics from seawater, according to a press release by the institution published on Thursday.

The scientists used the food substance to create an aerogel, a lightweight and porous material that can be used in many types of applications, including water filtration, energy storage, and sound and thermal insulation.

Princeton scientists discovered that egg whites can create a filtration process that requires only gravity to operate and wastes no water. They are now looking for other uses for the substance.
