BLASTIC developed new methodology and approaches to map sources, impacts and pathways of marine litter. Mapping approaches were combined with monitoring methods to produce the ‘BLASTIC riverine plastic litter monitoring method’ guidelines.
Additionally, BLASTIC also produced a list that identifies and prioritises measures to reduce litter streams from land to sea. The list helps municipalities to create local marine litter action plans. The guidelines and the list are accompanied by a socioeconomic report that looks at the impact of marine litter.
