Abstract: LALAP, ALLAN F. Formulation of Pelletized Compost Using Various Binders. Master's Thesis. Master of Science in Agriculture, major in Crop Science. Cavite State University, Indang, Cavite. August 2017. Adviser: Dr. Adolfo C. Manuel, Jr. This study was conducted to produce pelletized compost using various binders. It dealt strictly with testing the suitability of starches from arrowroot (Maranta arundinacea) and cassava (Manihot esculenta) as binding materials in pelletizing compost compared with a commercial synthetic pellet binder (Calcium lignosulfonate). Likewise the study also determined the optimum level of binding materials in pelletizing the organic fertilizer. It also identified which organic starch will have comparable effect in pelletization with that of commercial binder in terms of pellet durability and bulk density. Finally, nutrient contents (N, P, K, micronutrients and organic carbon) of the pelletized compost after inclusion of various binders with varying levels of inclusion were compared. The composting and pelletization was done at the Marinduque State College, Torrijos, Marinduque. The factors used in this study were the binders used and the different levels of inclusion. The compost produced through anaerobic composting was mixed with three types of binder: calcium lignosulfonate, arrowroot starch, and cassava starch with four levels of inclusion: 2%, 5%, 8%, and 10%. Pelletization was done using an extruder-type pelletizing machine. Arrowroot starch, cassava starch and calcium lignosulfonate were tested suitable as binding material in making pelletized compost. Mechanical properties were determined for the produced pellets. The average durability of pellets expressed as the Pellet Durability Index was 90.13 ± 1.82%. The average pellet bulk density was 535 ± 14.69g/cm3. An inclusion level of 2% calcium lignosulfonate was sufficient to improve pellet durability and bulk density. For most parameters evaluated, cassava starch used at 10% inclusion level revealed to be comparable with the commercial synthetic binder. Nutrient content of the pelletized compost was also analyzed. The average value of total NPK was 2.13 ± 0.339%; total Organic Carbon was 9.87 ± 1.78%; pH was 7.42 ± 0.5563; micronutrients were 154.02 ± 26.69ppm for Zn, 72.16 ± 14.58ppm for Cu, 375.83 ± 50.95ppm for Mn, and 7,906.38 ± 914.28ppm for Fe at an average moisture content of 33.49 ± 1.23%.
