Although the field of waste batteries and accumulators (B&A) recently has attracted lots of attention from general public and policy makers and the number of researches conducted with the application of system dynamic modelling has a wide application for waste management sector, there is still a lack of research regarding the complexity of problems within the waste B&A management. Thus in this paper the dynamic model for the management system of waste B&A has been studied. The model is applied for the case study of Latvia. The developed SD model allows the investigation of complex relations and simulation of effects from various policies within the management system of waste B&A, because the model incorporates non-linearities, feedbacks and delays. The results of sensitivity analysis show that the changes in the collection ratio and import rate have both high and at the same time in the opposite direction aimed influence on the amount of landfilled B&A. This paper shows that the introduction of innovation diffusion model for the sector of waste batteries and accumulators can decrease environmental pollution by up to 30.7 %. However, based on the developed system dynamic model, scenarios comprising other policies could also be simulated, evaluated and discussed.
