Grease trap waste and water hyacinth is a major problem of sewer clods and impedes water flow, a factor in flooding. Both of which can be proceeded for use as soil amendments. This research had two objectives: 1) to study the appropriate characteristics of the ratio between grease trap waste and water hyacinth for compost production and 2) to study the efficiency of compost from the growth rate of kale. The results of the analysis revealed that moisture, organic carbon, pH, conductivity, C/N ratio, nitrogen, phosphorus, and potassium are conformed to organic fertilizer standards of the Announcement by the Department of Agriculture: Criteria for organic fertilizers 2014, Thailand. Comparison of compost quality from macronutrients revealed that the ratio between grease trap waste and water hyacinth (2:1) was of the highest quality. Comparing the average growth rate of kale by plant height, a number of leaves, leaf width, leaf length, and fresh weight, found that the efficiency of compost containing grease trap waste and water hyacinth (2:1) affected the maximum growth rate of kale. In conclusion, the study found that the utilization of residues can reduce costs for waste management and increase resource renewal, which contributes to sustainability in future.
