Users of the Toolbox will find information on how to document and communicate their important work against marine litter. Effectively documenting and communicating one's work helps to raise awareness in the long term. It will aid to get the public and political decision-makers on board, to create networks and gain allies, to make one's work replicable, and to inspire others.

With the publication of this guide, the PROMAR teams hopes to motivate users in communication their important work and thereby contributing to the reduction of terrestrial waste streams that reach the sea.
