Based on analyzing colored and white plastic flakes, the output of the Virtual Chemist is a data sheet. This data sheet presents the ratio of different plastic types in the sample, as well as other contaminants such as wood, metal and even moisture. The computing algorithm combines images from different angles and incorporates volumetric data. The Virtual Chemist is capable to distinguish between more than 25 types of plastic and can perform the analysis even if the plastic is contaminated by fat or proteins. This ensures a high accuracy of the ratios and makes the data reliable.
