Work package 4 of the WasteForce project is aiming 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 results in four deliverables. The current deliverable 4.1 provides an inventory of needs and possibilities related to the information exchange mechanisms. 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.
