The SeeElefant is a multi-purpose ship converted into a recycling and energy vessel that will be stationed at sea. He takes over the marine waste collected by the SeeKühen with on-board cranes. The SeeElefant will have market-proven plant technology for sorting, crushing and processing marine litter on board. The entire plant technology of the SeeElefanten was designed in a standard container grid. This modular design makes the system scalable and can be flexibly adapted to the conditions at the site of use.
The plastic is sorted, pressed into plastic bales and recycled on land. In a later phase, plastic waste will also be able to be oiled directly on board. The oil extracted from plastic waste is stored in tanks of the ship. The process of plastic oiling consumes about 20-30 percent of the fuel produced, the rest can be sold directly to ships or settlements that are on the route. The proceeds will help to finance part of the project.
Organic residues and wood are to be converted into biogas or thermally recycled. Initially, the aim is to achieve a processing capacity of 20 t/day. In further stages of expansion, this system will also be developed for commercial operators with up to 200 t/day. According to calculations by One Earth – One Ocean e.V., two employees can collect about 200 tons of plastic waste per day.
For 10 months, a team of ship designers, plant engineers, environmental engineers and project developers worked in Kiel on the planning implementation of the first sea elephant.
In spring 2019, the comprehensive research and concept study on the elimination of coastal marine pollution from plastic waste was completed.
The focus is on the pilot system of a recycling vessel called SeeElefant. The results of the study confirm the technical, economic and legal feasibility of the pilot system “SeeElefant”.
Investors from the business community who want to participate in the construction of the first “Sea Elephant” pilot system in order to tackle the problem of plastic waste actively and pragmatically are cordially invited.
In 2019, oeoo was awarded the Federal Ecodesign Award of the Federal Ministry of the Environment for its concept of the sea elephant, the highest state award for ecological design in Germany.
Simply put, plastic oiling, as we are currently practicing with our technology partner BIOFABRIK and its solution WASTX Plastic , breaks the plastic back into its components. First, the plastic waste is crushed, cleaned and unsuitable plastics such as PVC or high-quality and recyclable plastics such as PET are sorted out. The remaining plastic mixture is then heated, melted and then evaporated to gas in a second step. Substances such as chlorine or sulphur which are not suitable for further processing are separated. The remaining gas mixture is condensed, so liquefies again. At the end of the process heating oil or diesel. The chemical process also provides bitumen coal, which is disposed of on land.
