Spectroscopy is being used to sort different kinds of plastic waste for recycling. Many plastics that are made from different polymers and require different recycling procedures are colorless and indistinguishable by eye, but techniques such as Raman and infrared spectroscopy, which are sensitive to the molecular vibrations in the sample, can be used to tell them apart.

Machine vision and imaging spectroscopy approaches have been successfully used for the identification of Japanese knotweed and can discriminate between different plant species in the same area. Other species, such as serica, can also be identified using such methodologies and instrumentation attached to airborne vehicles that can either be piloted remotely or run in autonomous modes.
