Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
An EU project improved recycling of agricultural plastics film waste. The group developed a logistics system, also a three-stage process for on-site removal of earth and rocks from the film, involving a dry airflow technology.
