The new filter, detailed in Separation and Purification Technology, is made out of corn protein rather than petroleum products like comparable filters.
Besides being plentiful, corn protein is also biodegradable, making it an environmentally-friendly alternative to the petroleum and glass products that most other filters are made of. Corn protein is hydrophobic as well, which may make the filters especially useful in certain products like facemasks.
These filters rely on the functional groups of the amino acids in the corn protein. These groups essentially “grab” toxins as they pass through the filter. The companies believe that they may be able to arrange the corn proteins in such a way that a “tentacle-like” set of functional groups could grab multiple types of pollutants from the air concurrently.
Manufacturing the filters is quite simple: the team uses polyvinyl alcohol to glue the corn protein nanofibers together into three-dimensional configurations, forming a lightweight material similar to foam.
The Global corn protein air filter market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Novel corn-based air filter captures wide variety of pollutants.
A research team from Washington State University has developed an air filter made out of corn protein instead of petroleum products that can concurrently capture small particulates as well as toxic chemicals like formaldehyde that current air filters can’t.
Particulate matter is not that challenging to filter but to simultaneously capture various kinds of chemic,al gas molecules, that’s more significant,These protein-based air filtering materials should be very promising to capture multiple species of air pollutants.
With micron-sized pores, typical high efficiency particulate air filters, also known as HEPA filters, can capture the small particles but aren’t able to capture gaseous molecules. They are most often made of petroleum products and glass, which leads to secondary pollution when old filters are thrown away
A new type of air filter made of corn protein instead of petroleum plastic appears to be better able of filtering out small pollutant particles as well as toxic chemicals like formaldehyde than current air filters, according to a press release from Washington State University.
