Abstract

This research investigated the potential application of blue-green algae to improve the quality of composts generated from multiple waste streams including the fly ash, fish waste, and sludge from a local wastewater treatment plant. The algae strain used is Anabaena 387, which was obtained from the Canadian Phycological Culture. Different mixture ratio of the fly ash, fish waste compost, sludge and algae were tested and different reaction periods were selected to generate multiple compost products. The parameters including the trace element concentrations, carbon to nitrogen ratio, pH level, moisture content, organic matter, and germination index were monitored to evaluate the quality of composts. Three levels of compost products were generated, which are Type AA, A, and B. The algae treated composts could be used as amendments for agriculture applications.
