In industrial recycling of waste plastics the on‐line sorting of different kinds of consumer plastics often represents the key to the successful commercial operation. The principle and a limited feasibility study of a novel wavelength independent photoacoustic sensor applied to this problem are presented. This wavelength independent sensor offers the advantages of low cost, portability, and is not limited by the surface modifications such a color, printed labels, etc. in the commercial products. © 1994 John Wiley & Sons, Inc.
