  • Potential of Combustion of Poultry Litter for Space Heating in Poultry
           Production

    • Abstract: Confined poultry production, which is expected to double by 2050, produces a lot of litter. For successful and sustainable poultry production, litter management is prompted and should be prioritized. Poultry litter can serve as an energy feedstock for space heating and electricity generation. Currently, heating systems in use depend on electricity, charcoal or diesel which are very expensive leading to high energy costs in poultry production. The purpose of this study was therefore to investigate the potential of combustion of poultry litter for space heating in poultry production. A brazier with 32 holes, of a diameter of 1cm, on its sides comprising of dimensions; Diameter=8 cm and Height=65 cm was used to burn 1kg of Poultry Litter Briquettes. The briquettes were made with a mincer which had a nozzle of dimensions, Length=11 cm and Diameter= 25 mm producing briquettes of a diameter of 25 mm and a length of 10 cm. The briquettes were made from poultry litter of chickens at the ages of 4, 5 and 6 weeks, and were either sun or solar dried. They were then directly combusted in the brazier and heat distribution was measured at distances of 30 cm, 60 cm and 90 cm from the brazier. Charcoal was used as a control. The maximum average temperatures recorded on the surface of the brazier for week 4, 5, 6 were 471oC, 491oC, 493oC respectively; whereas for charcoal was 555oC. However, the poultry litter briquettes were not able to sustain high temperatures for long compared to charcoal. Complete combustion took an average of 120 minutes while charcoal took an average of 180 minutes.

  • An Assessment of the Challenges affecting Smallholder Farmers in Adopting
           Biogas Technology in Zambia

    • Abstract: The objective of this study was to assess the challenges of adopting biogas technology among rural households in Zambia. Three hundred and twenty households with and without biodigesters were selected randomly from five provinces in the country for the study. A household survey and qualitative methods such as focus group discussions and key interviews were used to collect information. The results show that firewood and charcoal are the main sources of cooking energy in the study areas despite the enormous potential for the utilization of biogas. The use of biogas technology is in its infancy and few households have adopted the technology. The study found that several challenges or factors were responsible for the low adoption status of biogas technology in the study areas. The main challenges were the high cost of installation of biodigesters; lack or limited access to credit to help meet the costs of construction of biodigesters; inadequate numbers of skilled biodigester technicians; and lack of awareness or limited information on biogas technology. Increasing access to affordable credit, as well as awareness raising on biogas technology among rural households are suggested as some of the ways that will assist to promote the adoption of biogas technology as a sustainable renewable energy source for rural populations in Zambia.

  • Effect of Rice Bran on Continuous Organic Waste Decomposition Processes

    • Abstract: The mirobial decomposition process of househole waste, mainly food waste, is considered an environmentally friendly way to treat organic wastes. However, there are some problems which often occur, such as low conversion rate and bad smell generation, especially in the early stage of continuous operation systems. Rice bran has been known empirically as an acclerator or improving material for the microbial decomposition process of organic wastes. Unfortuantely, little information about the detailed findings has been obtained so far.This study intended to analyze the effect of rice bran as an activating agent in organic waste decomposition in order to minimalize the problems. Firstly, the effect of rice bran was confirmed. Reactor weight, temperature, moisture content, pH, and microbe number were measured and used as the parameters to confirm the effect of rice bran addition in the decomposition process. It was observed that the total waste reduction during the process was larger in the case of rice bran addition than that of the blank, i.e. without rice bran addition. The other parameters also showed similar tendencies, indicating that rice bran is surely capable of activating the decomposition process. Then, the growth accelerating effect for microorganisms in the composting process was examined by a cultivation test using trypticase-soy liquid medium. The microbe number in the medium with rice bran addition was higher than the medium without rice bran.Secondly, the factors contributing this effect were searched. Although we could narrow down the number of candidate constituent, among them magnesium was one of the major candidates, the precise identification was not possible, possibly because the effect of each nutrient on the microbes varies depending on the kind of microbial strain, and not a single but a combination of multiple nutrients may cause this effect. However, it was confirmed as a whole that rice bran shows a good influence on the growth of many micorbes in the composting process and accelerates the performance of decomposition.

  • The Form and Intensity of Community Participation in Conservation
           Management Program at Papua Barat Province

    • Abstract: This research aimed to determine the degree of participation of local communities in the management program of Gunung Meja natural recreation park and to provide alternative recomendations for the management based on community participation. Community participation in the management of the park was found to be the highest in the family group (46.15%), and the lowest in the leader group (5.13%). The same case was also found in the intensity of community participation. The participation of community includes leaders, interested groups, household heads, housewives and youth which was categorised as very inactive. This inactive result was influenced by community participation function which was in general only participating in activity implemention,information sharing and consultation. The management efforts were permit of natural tourism utilization and natural resources tourism infrastructure utilization, which can be used as the basis of the management program.

  • Thin Layer Drying and Modelling of Poultry Litter Briquettes

    • Abstract: Drying is an energy consuming process influenced by humidity, air velocity and temperature and is defined as a heat conveyance process wherein the product is heated hence removing moisture. Thin layer drying equations are used to estimate drying times of products and generalizing their drying curves. In this study, mathematical modelling and prediction of drying behavior of poultry litter briquettes (PLB) was investigated through open sun drying (OSD) and solar tunnel drying for moisture content (MC) calculations. A solar tunnel dryer (STD) having a: black painted collector unit, drying unit and black painted vertical bare flat-plate chimney was used. MC results were converted to moisture ratio and fitted into 12 different thin layer drying models, using Microsoft Office Excel, which were compared according to their coefficients of determination to estimate drying curves of PLB. The most accurate model was selected based on three statistical parameters: correlation coefficient (R2), chi-squared (χ2) and Root Mean Square Error (RMSE). Solar insolation of between 220 and 1005 W/m2 resulted in air temperature of up to 64oC at the collector unit, up to 60oC at the drying unit and an ambient temperature of up to 31oC. Exposure of PLB with an average initial MC of 61% (w.b.) to these conditions resulted in a final MC in a range of 0.2-11.2% (w.b.) in 31-55 hours. PLB was dried to similar final weight from whichever drying method although OSD took longer than STD. The Logarithmic model was found to satisfactorily describe the drying curves of PLB with R2 of 9.93E-01-9.99E-01; χ2 of 1.36E-11-6.50E-14; and RMSE of 2.94E-02-1.30E-02.

  • Possibility of Using Solar Energy for the Creation of Carbon Neutral
           Hotels in Mediterranean Countries

    • Abstract: Mitigation of climate change requires the increased use of renewable energy sources instead of fossil fuels in all sectors. Hotel buildings utilize large amounts of energy consuming mainly electricity while the use of renewable energy sources is rather limited. Solar energy is abundant in the Mediterranean basin and it is currently used for heat and electricity generation in many applications. Various solar energy technologies are mature, reliable and cost-effective. Use of solar thermal energy, and solar photovoltaic energy combined with the use of high efficiency heat pumps, can cover all the energy needs for domestic hot water, space cooling and electricity in summer-operating hotels in the Mediterranean region. A summer-operating hotel located in Crete, Greece with a covered surface of 3000 m2 has a specific annual energy consumption of 150 KWh/m2. The capital cost of the required sustainable energy systems for covering all the annual energy requirements in the hotel including a solar thermal system with flat plate collectors, a solar photovoltaic system with crystalline-Si modulus and high efficiency heat pumps has been estimated at 95.7 €/m2 while the annual CO2 savings due to the use of benign energy systems in the hotel have been calculated at 68 kgCO2/m2. It is concluded that the use of solar energy technologies in summer-operating hotels in the Mediterranean region could cover all their energy requirements, while it is technically feasible, economically profitable and environmentally desirable.
