The application of fruit coatings reduces gas exchange between the environment and the fruit by creating an additional layer to the fruit’s surface. If there is insufficient gas exchange, fruit coatings could induce anaerobic respiration and physiological disorders. Chitosan (CS) and nanosilica (NS) composite coatings for fresh ‘Carabao’ mango frui...

Direct measurement of gas transmission rates of coated commodities under controlled environmental conditions is needed in formulating coatings to extend the shelf life of fruits. The gas transmission rate of coated commodities, along with its respiration rate can be used to predict the level of modification of the internal atmosphere and the qualit...

Physical, thermochemical, and compositional analyses were performed on pigeon pea (Cajanus cajan) wood to determine its overall biomass characteristics. Pigeon pea is a minor crop locally known as kadios, usually grown in backyards, marginal lands, and insignificant land portions in the Philippines. In this study, pigeon pea wood is identified as a...

This chapter aims to discuss the strengths and weaknesses of Low-Carbon Technology (LCT) from the perspective of Intended Nationally Determined Contributions (INDCs) and its implications for regional cooperation. The chapter undertakes a Meta-Policy Analysis in order to determine the key LCTs that can significantly influence the INDC targets; deter...

This paper presents the findings of an expert working group of researchers from East Asian countries. The group was tasked with developing a theoretically sound and practically implementable methodology for assessing the sustainability of biomass utilisation in East Asian countries based on the needs and potential of biomass resources in this regio...

The study aims to determine the suitability of Jatropha (Jatropha curcas L.) wastes for charcoal briquette production. Three types of raw materials namely 100 % tuba-tuba husk, 50 % husk and 50 % pressed cake, and 100 % pressed cake were carbonized using FPRDI carbonizer. The carbonized materials were bonded with cassava and corn starch as binders...

A modified drum-type carbonizer was fabricated for the carbonization of young coconut waste. The major modification made was increasing the number of air inlets from four inlets per layer to eight inlets per layer, for three layers. Three tests were made by adjusting the number of air inlets opened. Water boiling test was performed using the three...

An energy balance analysis was performed to determine the energy efficiency of cassava bioethanol production in the Philippines. The analysis was based on a commercial scale production system and covered four segments in cassava bioethanol production: cassava production and cultivation, cassava processing, ethanol conversion and transportation. The...

In response to the importance of assessing both positive and negative impacts caused by biomass utilization for energy, number of initiatives in the world are currently working on development of criteria and indicators for sustainable biomass utilization. Although there is abundant biomass to be utilized in East Asia, it is difficult to say that co...

A study designed, fabricated, and optimized performance of a jatropha sheller, consisting of mainframe, rotary cylinder, stationary cylinder, transmission system. Evaluation and optimization considered moisture content, clearance, and roller speed as independent parameters while the responses comprised of recovery, bulk density factor, shelling cap...

The overall vision of the Philippine government is the reduced dependence on imported energy through environmentally desirable options such as the use of bioethanol. Sugarcane is considered to be tested and ready for bioethanol production. This paper presents the value addition from sugarcane production to processing into bioethanol as well as the...

This paper showed the abatement cost and the amount of GHG emission reduction if charcoal cookstove is used instead of fossil fuel-based cookstove such as kerosene and LPG cookstoves. The abatement cost per tonne emission reduction is calculated as the net present value (NPV) of the incremental cost between the fossil-based and the charcoal cooksto...

This paper presents the findings of an expert working group of researchers from East Asian countries. The group was tasked with developing a theoretically sound and practically implementable methodology for assessing the sustainability of biomass utilisation in East Asian countries based on the needs and potential of biomass resources in this regio...

Developing countries source majority of its energy for cooking from biomass mainly, wood and charcoal. Performance of the Improved Bioflame Stove using coconut rachis as solid fuel at different moisture content and length, and with varying area of air opening of the stove was evaluated through the following indicators: thermal efficiency, specific...

In order to provide decision-making methodology to evaluate sustainability of biomass utilisation in East Asian context, an expert working group has been formed since 2007 and has been conducting researches to assess the sustainability of biomass utilisation with the concept of triple bottom line focusing on environmental, economic and social pilla...

This paper provided an analysis of the commodity chain from coconutproduction as feedstock for biodiesel production (called Coco Methyl Ester or CME) as well as the value addition from its production and processing. The value-added for the industry included the summation of all the value-added in each enterprise, which includes personnel remunerati...

In this study, assessment methodology for biomass sustainability is introduced. An expert the Economic Research Institute for ASEAN and East Asia (ERIA) working group on "Sustainability Assessment of Biomass Utilisation in East Asia" developed guidelines for sustainable utilisation of biomass for energy in East Asia. Due to test and adjust the guid...

The determination and optimization of drying characteristics of the janitor fish was studied using the regression surface methodology. Fish samples were subjected to drying air temperature of 50 degrees C, 60 degrees C, and 70 degrees C; 0.21, 0.24, and 0.27 ms(-1) air velocity, and cuts 1, 2 and 3. The responses observed were average drying rate,...

The performance of a fabricated direct-fired corncob furnace was evaluated to determine best combinations of operating parameters involving fuel feed rate, combustion air, and fuel size. The furnace had the following components: hopper; rotary feeder; variable motor; inclined grate; and horizontal grate. The furnace wall was made up of cement and r...

This paper aims to develop a framework of strategies for successful technology transfer in the Philippines, particularly for biomass energy technologies (BETs). Evaluation of nine candidate BETs using seven selection criteria resulted in identification of three most promising BETs for the Philippines namely: Stirling engine, cogeneration and bio-di...

This study assesses the sustainable energy potential from non-plantation biomass resources in the Philippines. Biomass resources considered for energy potential were agricultural residues and animal manure; fuelwood and charcoal that can be potentially released due to efficiency improvements, and substitution by other fuels; municipal solid wastes;...

This study aims to estimate land availability for biomass production, identify and evaluate the biomass production options in terms of yield per hectare and financial viability, estimate sustainable biomass production for energy, and estimate the energy potential of biomass production in the Philippines. In estimating the area for biomass productio...

This study aims to analyse the policies pertaining to and the barriers to the commercialisation of biomass energy technologies in the Philippines and to devise suitable policy measures to overcome these barriers. The barriers are categorised into five different types: market and finance-related barriers, technological barriers, information dissemin...

Total energy consumption in the Philippines in 1995 is estimated to be about 32.45 million tons oil equivalent (MTOE) in which share of biomass is about 11.5 MTOE or 35.45%. Shares of woodfuel, agricultural residues and charcoal in the total biomass use for energy were 57%, 39%, and 0.04%, respectively. Only about 20% of the potentially available b...
