Since it is technically and economically impossible to reduce the amount of plastic waste in oceans, solutions to cut the entry of such substances into the environment must be developed. Developing countries, however, often lack land-based approaches to such solutions. Unused plastic waste actually represents a missed work and income opportunities in less-developed countries, particularly for less-educated people. Valuable plastic wastes usually enter into the environment in these areas, which in turn constitute a significant point of entry into the oceans. The project developed concepts and implementation planning of an infrastructure for recording, boat-based processing, and marketing of plastic wastes in order to reduce their entry into the environment and marine ecosystems. The programme targeted less-developed countries, with an aim to create supply chains for trade and utilisation of plastic waste as well as to create added value for the people in the target countries. The programme targeted the source of the problem and thus reduced the entry of plastic waste into the ecosystem.
Main areas of work
- Data collection, analysis and evaluation (local conditions in less developed countries)
- Preliminary planning of waste treatment plants
- Design of a concept for suitable ship and plant technology
- Development of strategies for the implementation of value chains in less developed countries
- Analysis and evaluation of results (economic, ecological)

Short description
It was of utmost importance for the processing of the entire project to gain knowledge of the composition of the plastic waste that potentially was collected in less developed countries. To this end, data and information (types, qualities, quantities, framework conditions, logistics, etc.) were first collected, analysed and evaluated, including on site in the example countries Sierra Leone and Mauritius.
WP 2 Pre-design of a treatment and recovery plant

Short description
In this WP, waste treatment plants were planned in various variants. For this purpose, national and international framework conditions connected with the construction and operation of the ship-based facilities to be developed were determined. Various known procedures were evaluated and tested for their suitability, as were requirements for operation, maintenance and repair. On this basis, the objectives for the treatment of plastic waste were defined, followed by the development of conceptual designs.
WP 3 Concept development (ship and plant engineering)

Short description
Preliminary designs for up to three variants of carrier vessels/semi-submersibles for the treatment of plastic waste were developed with alternative shipbound logistics concepts. Rough planning included room planning and process-oriented arrangement of facilities, equipment for maritime technology, equipment for waste treatment plants, etc. The production costs and energy requirements were also determined and the variants were compared economically.
WP 4 Marketing potential of secondary raw materials

Short description
The market for secondary raw materials was examined, since these are fundamentally valuable. Tradeable products from plastic waste were identified and the quality requirements to be met specified. Possible revenues were also estimated. The resulting technical requirements for processing technology and quality management were taken into account in the other WPs. Based on the results, strategies for the most economical processing and marketing of products made from plastic waste were developed.
WP 5 Profitability analysis and life cycle assessment

Short description
The concepts and preliminary planning for the ship-based collection, processing and marketing of plastic waste from less developed countries developed in the project were evaluated under economic and ecological aspects. On the basis of the results, the ecological advantages (reduction of the input of plastics into the environment, protection of resources by recycling plastic waste) were determined. The evaluation of the economic efficiency was intended to assess the chances of realisation and provide a planning framework for potential investors, funding providers and operators of a ship-based collection and treatment plant for plastic waste.
WP 6 Project management, public relations, recycling concept

Short description
WP 6 covered work on internal and external communication (project meetings, workshops, communication between national and international partners including maintaining contacts with interested shipping companies/owners, public relations work etc.) and project management (administrative and content reporting, work and progress control and coordination etc.).
