Work package 4 of the WasteForce project (https://www.wasteforceproject.eu/) aims at supporting international operational networking between the EU and the Asia-Pacific region through information-sharing activities and dedicated training materials. The project will contribute to build stronger relationships among key stakeholders in the cross-border waste chain that can continue after the project. WP4 will result in four deliverables: Deliverable 4.1 provides an inventory of needs and possibilities related to the information exchange mechanisms; The current deliverable 4.2 is an assessment of information exchange mechanisms for international operational networking; Deliverable 4.3 provides guidance on prosecuting Waste Crime; and Deliverable 4.4 is a collection of good practices to support the EU-Asia collaboration, especially on the repatriation of illegal waste shipments.
