LWV21204 Sustainable and Circular Organic Waste and Sargussum Management on Bonaire (BO-65-002-003)

Because of the diversity of wastes, several applications will be studied: 1) Direct applications for food/feed products, 2) Applications of (mixed) organic waste streams, digestate from anaerobic digestion and wastewater as substrate for compost or soil enhancers (reducing imports of comport and fertilizer) and 3) The production of biogas (for electricity generation, replacing fossil diesel) and digestate based compost from the organic wastes and Sargassum. Depending on the content in heavy metals, or other toxic components of the organic wastes, “clean” and “polluted“ conversion systems will be designed. This will avoid that polluted organic wastes enter the feed and food chain or end up on agricultural land (compost) or nature. Environmental, social and economic impacts will be assessed for the value chains. In addition, knowledge exchange will be realised with other Caribbean (Dutch and French) islands by joint events (workshops, meetings, etc) to maximize the impacts and efficiency of the project.
