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.
 
The project tested its methodology in pilot areas, where concrete plastic marine litter was removed. The pilot along with the created materials served the general aim to increase knowledge and awareness about plastic, micro plastics and hazardous substances among different target groups. As part of this, a knowledge bank (https://www.blastic.eu/knowledge-bank/) was setup.
