The Circular Plastics Alliance initiative aims to boost the uptake of recycled plastics (as regranulates) up to 10 million ton by 2025. Consequently, the demand for regranulates in Belgium and the Netherlands is expected to increase as electronic producers begin to pledge to use 25 % regranulates in their products by 2025 or 2030. Therefore, this research aims to gain insights into the potential of regranulates to be used in vacuum cleaners, coffee machines, and electric shavers, which are products with a fair amount of plastics concentration in the small household appliances (SHA) category of electrical and electronic equipment (EEE). A model is developed to forecast the amount of waste electronic and electrical equipment (WEEE) generated in 2030 in Belgium and the Netherlands using multivariate input-output analysis. The amount of regranulates released by the current formal WEEE management systems of SHA waste is quantified using material flow analysis, which equal to 22 %. This research indicates the need of improved collection rate and pre-processing efficiency (dismantling, shredding, and sorting) to at least 64 % to achieve the target of using recycled content in EEE. Moreover, up to 5 % of WEEE may still contain hazardous substances like brominated flame retardants by 2030. Lastly, through scenario analysis, we predict that the target to use recycled content in vacuum cleaners can be realized by 2027 or by 2023 in the base and positive scenario respectively, regardless of the changes in material composition as long as the collection and pre-processing technologies are continuously improved.
