AYOS, ANSEL CHRISTIAN JAMIL D., POLINGA, CAMILO JR. E., ROSELL, SAGE JOSEPH P., and SANGALANG, REINIEL DAREN E.. Applied Research IV, Cavite State University Science High School, Indang, Cavite.” DEVELOPMENT AND EVALUATION OF A PORTABLE HOUSEHOLD COMPOSTER’”. Thesis Adviser: Dr. CAMILO A. POLINGA
The study on “Development and Evaluation of a Portable Household Composter” was conducted at the Faculty Village, Cavite State University, Indang, Cavite from August 2004 to February 2005. It aimed to develop, fabricate and evaluate a composter that can be used for composting household garbage. The composter was evaluated in terms of retention time.
The shortest retention time recorded was 7 days with a stirring duration of 10 turns applied two times a day (8am and 5 pm). This indicates that the garbage loaded on Saturday which is market day can be harvested on the next market day (Saturday) which is also the schedule for the next loading.
The temperature of the compost materials is affected by the duration and frequency of stirring the substrate. The highest temperature recorded was 51.4 deg. C.
Generally, there was a decrease in the Carbon to Nitrogen (C/N) ratio of the final product. The range of 18.6 to 31.2 is within acceptable limit for compost and
composting.
The Nitrogen-Phosphorus-Potassium (NPK) content of the compost product is sufficient for a good soil conditioner.
The recovery rate of the composter is 25.7 percent (air-dried compost). The cost of the machine was P 1,250.00
