The study entitled “Comparative Assessment of Management Options of Biodegradable Public Market Wastes of General Trias, Cavite” was conducted at General Trias, Cavite from August 2016 to March 2017. Specifically, the study aimed to: (1) characterize the biodegradable wastes generated from the public market of General Trias City; (2) quantify the amount of biodegradable wastes generated from the public market in terms of volume and weight; (3) determine the biogas production of biodegradable waste from public market of General Trias, City; (4) produce compost using biodegradable wastes of General Trias City public market; (5) determine the nutrient content (NPK) and soil pH of the compost; (6) design a suitable biogas plant for the public market of General Trias City; and (7) conduct economic analysis of composting and biogas production options.
The study was limited on fruit and vegetable wastes and fish entrails. The total weight of the biodegradable wastes generated for 7 consecutive market days was 779.60 kg with an average weight of 111.40 kg every market day, while the total volume of wastes generated was 1.118 m° with an average volume of 0.159 m3 every market day.
For biogas production, two treatments with varying frequency of agitation, namely: Treatment 1 (daily agitation) and Treatment 2 (every other day agitation) with three replications. The quantity of gas produced was determined using the displacement method. Treatment 1 had a total mean of 44,220 mL of biogas produced for a maximum retention time of 41 days and Treatment 2 with 42,258.33 mL for 41 days.
The square type DSAC model was used as design of a biogas plant for the public market of General Trias, Cavite. A total digester volume of 10 m was designed.
For compost production, three treatments with varying frequency of agitation, namely: Treatment | (daily agitation without EM"), Treatment 2 (no agitation with EM*) and Treatment 3 (daily agitation with EM”) and replicated three times. Treatment 1 has a mean peak temperature of 52.0°C with a composting time of 14 days and a composted mass of 9.13 kg. Treatment 2 has a mean peak temperature of 47.8 °C with composting time of 20 days and a composted mass of 9.18 kg. Treatment 3 has a mean peak temperature of 50.3°C with composting time of 12 days and a composted mass of 9.18 kg.
