| The energy use and CO2 emissions of eggplant production in the Philippines were analyzed from data collected from 202 eggplant farmers randomly selected from the two major producing provinces of Pangasinan and Quezon, Philippines. Accordingly, the input and output energy of eggplant production were 77,342.09 MJ/ha and 233,905.50 MJ/ha, respectively. Diesel fuel and chemical fertilizer contributed the largest share of energy used in eggplant production. Most of the input energy was utilized in preharvest operations among which the application of fertilizer and water irrigation consumed the largest energy. The energy ratio and energy productivity were 3.02 and 0.51 kg/MJ, respectively. Direct and indirect forms of energy constituted 60.93% and 39.07%,... |

| The study determined the postproduction handling systems, losses and the needed intervention to improve the fresh sweet potato chain. Surveys were conducted among 350 sweet potato farmers in four major sweet potato producing provinces supplemented by the key informant interviews, focus group discussion and on-line search of secondary data. Actual loss assessments were undertaken adapting the tracing method and following two commercial marketing channels replicated 6 times for each marketing channel. The total average postharvest loss was 32.09 percent. Among the postproduction operations, quantity losses during harvesting were the highest at 15.96 and 17.94 percent for Bataan and Tarlac, respectively. Along the fresh sweet potato market chain, the farmer... |

| The performance of PHilMech cabinet dryer in drying mango slices was evaluated in terms of efficiency, product quality and cost. The dryer, originally designed with kerosene burner and rice hull furnace as heat source, was retrofitted with liquefied petroleum gas (LPG) heating system. Its performance was likewise compared with existing dryers of Pangasinan Tropical Fruits Multi-Purpose Cooperative (PTFMPC) in Manaoag, Pangasinan, Philippines. Results showed that mango slices with initial moisture content from 65.4 to 72.4 percent were uniformly dried in 9.5 to 10 h to final moisture content of 9.6 to 9.7 percent using an average drying temperature of 53.2 to 54.2 oC using the PHilMech dryer. The LPG heating system had higher heating system efficiency than... |

| Four corn production systems at farmer-level of operation were evaluated. Environmental performance such as energy use, energy efficiency, greenhouse gas emission (GHG) and carbon efficiency were determined. Data were collected from 60 corn producing farmers using survey questionnaires and face to face interview. The input energy to produce an output energy of 69,714.06 and 73,029.60 MJ/ha for sun drying and mechanical drying, respectively, were 22,346.27, 31, 469.75, 22, 399.05 and 31,522.53 MJ/ha for systems 1 (manual harvesting and sun drying), 2 (manual harvesting and mechanical drying), 3 (mechanical harvesting and sun drying) and 4 (mechanical harvesting and mechanical drying), respectively. The highest energy input was observed for system 4... |

| Biomass furnace ash (BFA) generated from drying of grains in mechanical dryers were blended with cement in varying ratio of 1:4, 1:5, 1:6, 1:7 and 1:8 by volume. Each composition was cured in an ambient condition for 7, 14 and 28 days and determined their properties such as density, porosity, compressive strength and thermal shock resistance. Cold crushing strength increased with increasing cement content and curing time. Likewise, density increased with increasing cement content and curing time while porosity showed the other way. All the sample compositions exceeded 30 cycles without any crack when subjected to thermal shock resistant cycles of heating and cooling using a firing temperature of 1000oC in an electric muffle furnace. |
