Answer

Yes, plastic pepper grinders can produce microplastics over time. When plastic items are used, they can wear down due to friction, heat, and other mechanical forces, leading to the release of tiny plastic particles known as microplastics. This process can be influenced by factors such as the hardness of the peppercorns, the frequency of use, and the quality of the plastic used in the grinder. To reduce the potential for microplastic generation, consider using grinders made from other materials, such as stainless steel or ceramic, which are less likely to degrade and produce microplastics.
