Europe aims at climate neutrality by 2050; to achieve this, plastic recycling needs to be increased through better processes and technologies. There is an increasing need for measurement technology that enable efficient identification of different pl

Plastic waste volumes are globally expected to increase from 260 million tons per year (2016) to 460 million tons per year by 2030. In Europe, industrial and private end-users consumed about 55 million tons per year in year 2018. Only about 17 % of t

Despite the new definition of the Kilogram, physical weights prone to contamination will still be used in the dissemination of the unit. Cleaning is applied to bring the weight surface to a well-defined state to allow predictable adsorption behaviour
