Cellulose is a natural component of plants, and nano-cellulose is isolated from them through various technical processes (e.g. from sugar beet, wood, pineapple fibers, etc.). In this respect, any exposure to the environment of technically produced nanocellulose is difficult to differentiate from the naturally occurring cellulose.

 

In one study the nano-cellulose content of ambient air during manufacturing (milling and drying process) was investigated. When the machines are correctly operated no or only very small numbers of particles are detected, and under normal conditions a small air-borne exposure through the production process is assumed [1]. There is currently no data available regarding other exposure routes such as through use or wastewater.
