solid waste management


Waste management is an essential strategy for controlling the by-products humans, and other organisms produce daily. Biodegradable waste can easily be decomposed and promotes microbial activity as an effective component of making nutrient-rich compost for plants. There are several types of composters to hasten the composting process. In this study, a pedal-operated composter was designed, made, and used in the process of making organic compost. Results showed many favorable attributes. Using 2:2:1 and 1:1:1 ratio of dried leaves, manure, and rice bran, respectively, evaluation and proper handling were observed. Ambient and compost temperatures were collected every two days in daylight hours. Results showed that both ratios achieved similar results and yielded a mature compost on the 26th day of the composting period. The characteristics of composts produced satisfied the selected indicators of the Philippine national standards for organic compost. Further studies should be conducted on these aspects: chemical analyses on the composts, composter's ability to composting other materials (such as food waste products and community waste), and test the compost's effects on the plant's growth and development.
