For the Second International Conference of the African Marine Waste Network

Towards Zero Plastics to the Seas of Africa

23-27 May 2022, Boardwalk Convention Centre, Nerlson Mandela Bay, South Africa

Who we are

Sustainable Seas Trust is a Non-Profit Organisation (NPO) that supports and connects communities across Africa through research, education, enterprise development and growing awareness about ocean conservation and plastic pollution. We also build networks, for sharing information and support, focused on waste management. Through our events and projects, the African Marine Waste Network, Hope Spots and Marine Education, we are bringing like-minded and passionate people together, locally and internationally, to manage the issues of plastic waste in Africa.


Why our work is important: Africa has some of the most exquisite, biodiverse and marine-rich coastlines in the world. We need to protect them. Waste-focused studies predict that by 2050 there will be more plastic littering Africa and entering its seas than any other continent. This vast pollution, combined with habitat destruction and over-fishing, stands to collapse the ocean’s ecosystems. That is not only a threat to our environment/ oceans, but also to us humans. In addition, addressing poverty and human health are fundamental in the fight against marine pollution. Healthy communities lead to a healthy environment.


Our mission

To grow a network of stakeholders in the conservation and waste-management sectors to facilitate best practices around conservation of Africa’s seas, and the management of waste at source, before it flows into them.

Our Projects

SST protects Africa’s oceans through education on plastic waste, conservation and fostering enterprise development 

African Marine Waste Network

Our AMWN works to develop better waste-management strategies in Africa and foster enterprise development.

Hope Spots

These are marine areas of ecological and biodiversity significance around the world.  There are six Hope Spots in South Africa.  

Marine Education

Our programmes teach people about the coastal ecosystem and the effects of plastic pollution.

This is all that should be floating in the ocean

Plastic pollution has a huge negative impact on the marine ecosystem. Our programmes work towards tackling plastic pollution at its source: on land.
