The Biotank is a waste cleaning product developed by UGV and Bioremediation Africa to promote clean environments in West Africa. It uses three natural components - the Digester, Filter, and Cleaner - to break down, filter, and treat household waste on-site. The processed water can then be reused for gardening or domestic purposes. The Biotank reduces pollution from sewage trucks and the need for septic tank emptying. It is a cost-effective and space-efficient way to safely manage liquid waste and promote more sustainable sanitation practices.
