    Rice straw is a promising renewable energy source because it is abundantly available in Asia. This study conducted a case study of logistics cost analysis for rice straw pellets by considering all stages in the supply chain to define the main factors affecting the selling price of rice straw pellets: collection (job commission or employment of part-time workers), transportation, storage (vinyl greenhouses or storage buildings with larger capacity), pelletizing, and delivery to users with biomass boilers. The selling price was found to be strongly dependent on the production capacity because the investment cost for the pellet production facility had a significant effect of economies of scale. A production capacity of larger than 1500 t y(-1) is required for rice straw pellets to compete with wood pellets and fossil fuels in the studied Japanese context if the subsidy rate for the investment is 50%, part-time workers conduct the collection, and rice straw is stored in the storage buildings. Our sensitivity analysis also showed an economically feasible spatial scale: for example, rice straw should be collected within a 20 km radius and the users should be within a 38 km radius when the production capacity is 1500 t y(-1). In addition, other critical factors related to the collection of rice straw from the paddy fields and transportation of rice straw rolls to storage were identified as planning factors to further reduce the total logistics cost of rice straw pellets.

    The high methane gas production potential of two phase olive milling waste (2POMW) makes its application to biogas plants in business an economical process to increase the productivity of the plants. The objective of this study was to investigate the appropriate conditions for the codigestion of NaOH-pretreated 2POMW with food waste. NaOH pretreatment can increase the methane production by increasing the soluble chemical oxygen demand (sCOD), but it may cause inhibition because of higher levels of alkalinity, sodium ion, volatile fatty acids and long chain fatty acids (LCFAs). Therefore, the first experimental phase of this study aimed to investigate the effect of different mixing ratios of 2POMW to food waste. A continuous stirred tank reactor experiment with different mixing ratios of 3%, 4.3%, 5.7% and 8.3% (2POMW: food waste) was conducted. NaOH pretreatment in the range of 6-20% was used. A mixing ratio up to 4.3%, when 10% NaOH pretreatment was used, caused no inhibition and increased methane production by 445.9 mL/g-VS(2POMW). For this mixing ratio an additional experimental phase was conducted with the 20% NaOH pretreatment as the 20% NaOH pretreatment had the highest sCOD. The methane gas production was increased by 503.6 mL/g-VS(2POMW). However, pH adjustment was required for applying this concentration of the high alkalinity 20% NaOH-pretreated 2POMW. Therefore, we consider using 10% NaOH pretreatment in a mixing ratio of 4.3% to be more applicable. The increase in methane gas production was correlated to the oleic acid concentration inside the reactors. The high oleic acid concentration of 61.8 mg/L for the 8.3% mixing ratio was responsible for the strong inhibition. This study showed that adjusting the appropriate mixing ratio of the NaOH-pretreated 2POMW could increase the electricity production of a reactor that regularly receives food waste.

    A step of pretreatment prior to anaerobic digestion has been widely studied to enhance biogas production from lingocellulosic biomass. In this study, alkaline pretreatment and mechanical pretreatment by size reduction were tested on the two phase olive mill waste (TPOMW) in order to facilitate the degradation of lignocellulosic organic matter and thereafter the subsequent bioconversion to methane. For alkaline pretreatment, NaOH and CaO with concentrations in the range of 2.4 % to 30 % were tested. Following pretreatment, anaerobic digestion was conducted in batch mode for 26 days. Mechanical pretreatment did not increase the soluble compounds, measured as soluble chemical oxygen demand (sCOD), nor improved methane production. On the other hand, both CaO and NaOH were able to degrade part of the lignocellulosic organic matter to more easily degradable organic compounds. Especially NaOH was strong enough to solubilize part of the lignocellulosic organic matter sCOD was increased to 265 ± 49.5 g O2/kg after pretreatment with 30% NaOH compared with 74.1 g O2/kg for the untreated TPOMW. However, inhibition because of high initial alkalinity or high sodium ion concentration was recognized for high NaOH dosage. Six percent NaOH increased methane production by 20.3% and 11.2% compared with the untreated and the CaO pretreated TPOMW respectively. Although NaOH concentration of 6% was found to be reasonable for improving methane production without pH neutralization, considering a full scale reactor system receiving food waste as a main substrate and the NaOH-treated TPOMW as a co-substrate, the NaOH concentration of 20% might be optimum regarding the soluble COD concentration.

    A large amount of rice straw is generated and left as much in paddy fields, which causes greenhouse gas emissions as methane. Rice straw can be used as bioenergy. Rice straw pellets are a promising technology because pelletization of rice straw is a form of mass and energy densification, which leads to a product that is easy to handle, transport, store and utilize because of the increase in the bulk density. The operational conditions required to produce high quality rice straw pellets have not been determined. This study determined the optimal moisture content range required to produce rice straw pellets with high yield ratio and high heating value, and also determined the influence of particle size and the forming temperature on the yield ratio and durability of rice straw pellets. The optimal moisture content range was between 13% and 20% under a forming temperature of 60 or 80 degrees C. The optimal particle size was between 10 and 20 mm, considering the time and energy required for shredding, although the particle size did not significantly affect the yield ratio and durability of the pellets. The optimized conditions provided high quality rice straw pellets with nearly 90% yield ratio, >= 12 MJ/kg for the lower heating value, and >95% durability. (C) 2014 Elsevier Ltd.

    Long term methane emissions from landfill sites are often predicted by first-order decay (FOD) models, in which the default coefficients of the methane generation potential and the methane generation rate given by the Intergovernmental Panel on Climate Change (IPCC) are usually used. However, previous studies have demonstrated the large uncertainty in these coefficients because they are derived from a calibration procedure under ideal steady-state conditions, not actual landfill site conditions. In this study, the coefficients in the FOD model were estimated by a new approach to predict more precise long term methane generation by considering region-specific conditions. In the new approach, age-defined waste samples, which had been under the actual landfill site conditions, were collected in Hokkaido, Japan (in cold region), and the time series data on the age-defined waste sample's methane generation potential was used to estimate the coefficients in the FOD model. The degradation coefficients were 0.050 1/y and 0.062 1/y for paper and food waste, and the methane generation potentials were 214.4 mL/g-wet waste and 126.7 mL/g-wet waste for paper and food waste, respectively. These coefficients were compared with the default coefficients given by the IPCC. Although the degradation coefficient for food waste was smaller than the default value, the other coefficients were within the range of the default coefficients. With these new coefficients to calculate methane generation, the long term methane emissions from the landfill site was estimated at 1.35 x 10(4) m(3)-CH4, which corresponds to approximately 2.53% of the total carbon dioxide emissions in the city (5.34 x 10(5) t-CO2/Y).

    Land use at contaminated sites, following remediation, is often needed for regional redevelopment. However, there exist few methods of developing economically and socially feasible land-use plans based on regional needs because of the wide variety of land-use requirements. This study proposes a new needs analysis method for the conceptual land-use planning of contaminated sites and illustrates this method with a case study of an illegal dumping site for hazardous waste. In this method, planning factors consisting of the land-use attributes and related facilities are extracted from the potential needs of the residents through a preliminary questionnaire. Using the extracted attributes of land use and the related facilities, land-use cases are designed for selection-based conjoint analysis. A second questionnaire for respondents to the first one who indicated an interest in participating in the second questionnaire is conducted for the conjoint analysis to determine the utility function and marginal cost of each attribute in order to prioritize the planning factors to develop a quantitative and economically and socially feasible land-use plan. Based on the results, site-specific land-use alternatives are developed and evaluated by the utility function obtained from the conjoint analysis. In this case study of an illegal dumping site for hazardous waste, the uses preferred as part of a conceptual land-use plan following remediation of the site were (1) agricultural land and a biogas plant designed to recover energy from biomass or (2) a park with a welfare facility and an athletic field. Our needs analysis method with conjoint analysis is applicable to the development of conceptual land-use planning for similar sites following remediation, particularly when added value is considered.

    Proper countermeasures are needed for remediation of illegal dumping sites of hazardous ma-terials such countermeasures should be based on the distribution of both the waste layer and contaminated groundwater. However, because of limitations in the number of borehole points, the precise distribution of the waste layer and contaminated groundwater cannot be enough de-termined only by conducting conventional bore exploration. On the other hand, a low-resistivity area obtained by the electrical resistivity survey can detect both the waste layer and contami-nated groundwater. However, distinguishing between the waste layer and contaminated groundwater is impossible by the resistivity survey alone because the resistivity is a relative value. This study proposes an estimation method of the distribution of both the waste layer and contaminated groundwater in illegal dumping sites so that the limitations of each investigation method could be compensated. Especially, this study introduces analysis of geological charac-teristics such as the permeability of soils around the waste layer to distinguish between the waste layer and contaminated groundwater. As a result of applying our method to three actual illegal dumping sites, the distribution of both the waste layer and contaminated groundwater was estimated separately.

    Bottom ash from Municipal solid waste incineration (MSWI) is a main type of waste that is landfilled in Japan. The long-term elution of organic matter from the MSWI bottom ash layers is a concern because maintenance and operational costs of leachate treatment facilities are high. In closed system disposal facilities (CSDFs), which have a roof to prevent rainfall from infiltrating into the waste layers, water must be supplied artificially and its quantity can be controlled. However, the quantity of water needed and how to apply it (the intensity, period and frequency) have not been clearly defined. In order to discuss an effective watering plan, this study proposes a new washout model to clarify a fundamental mechanism of total organic carbon (TOC) elution behavior from MSWI bottom ash layers. The washout model considers three phases: solid, immobile water and mobile water. The parameters, including two mass transfer coefficients of the solid-immobile water phases and immobile-mobile water phases, were determined by one-dimensional column experiments for about 2 years. The intensity, period and frequency of watering and other factors were discussed based on a numerical analysis using the above parameters. As a result, Our Washout model explained adequately the elution behavior of TOC from the MSWI bottom ash layer before carbonation occurred (pH similar to 8.3). The determined parameters and numerical analysis suggested that there is a possibility that the minimum amount of water needed for washing out TOC per unit weight of MSWI bottom ash layer could be determined, which depends on the two mass transfer coefficients and the depth of the MSWI bottom ash layer. Knowledge about the fundamental mechanism of the elution behavior of TOC from the MSWl bottom ash layer before carbonation occurs, clarified by this study, will help ail effective watering plan in CSDFs.

    We are developing a bioreactor system for treating dioxin-contaminated soil or water using the dioxin-degrading fungus, Pseudallescheria boydii (P. boydii). In order to design the bioreactor system, this study estimated the rate at which R boydii degraded 2.3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD), which is the most toxic of the dioxins. The experimental results showed that P. boydii degraded 2,3,7,8-TCDD during its logarithmic growth phase, using glucose as a carbon source for growth, and that the growth of P. boydii was not affected by 2,3,7,8-TCDD concentrations usually found at contaminated sites. These results were then used to apply successfully an existing mathematical model to the degradation of 2,3,7,8-TCDD by P. boydii. This allowed an estimation of the rate of degradation of 2,3,7,8-TCDD by P boydii that can be used in the design of the bioreactor system. (C) 2008 Elsevier B.V. All rights reserved.

    We proposed an improved numerical design method for the remediation of contaminated sites based on a sensitive tracer test using rare earth metals such as holmium. The numerical design method was then applied to a real contaminated site, where immediate counter-measures were required because of detection of high arsenic concentration in a spring near a sea line outside the site. First, the sensitive tracer test using insium, europium and holmium under natural gradient condition revealed the groundwater flow path from the three suspected source points to the sea line, and analysis of the breakthrough curve for each tracer compounds determined the parameters, such as the hydraulic conductivity and dispersivity. A site-specific model representing the distribution of aercenic concentration in groundwater identified the source points, responsible for the contamination of the spring, and revealed that contaminated groundwater might flow out of the site boundary. A vertical wall was designed to prevent contaminants spreading from the site, and the change in the arsenic concentration after the construction of the vertical wall was predicted. The prediction had similar tendency to the actual decrease in arsenic concentration over a two-year monitoring phase. Consequently, our numerical design based on the sensitive tracer test predicted that the contamination level in the groundwater around the spring would continuously decrease toward remediation.

    In Japan, most farm animal excreta has been stored directly on farmland. Runoff from this storage has often Caused water pollution. Biogasification is anticipated as an important technology to manage excreta properly, but complex problems hinder its introduction. Economic aspects of management have been especially difficult for dairy farmers. For this study, structural problems regarding introduction of biogasification into dairy farming were identified. Subsequently, a desirable system of dairy farming including biogasification was suggested, and an evaluation model of the financial balance was constructed. A case study using current financial balances of several systems of dairy farming wits evaluated using the constructed model and actual data. The systems were based on several policy alternatives including the suggested system mentioned above. Results show that a farmer can obtain sufficient income from a system featuring centralization of dairy housing and biogasification facilities and coordinated management by over six farmers.

    The Analytic Network Process (ANP) has been proposed to incorporate interdependence and feedback effect in the prioritization of remedial countermeasures using a hierarchical network decision model, but this approach seems to be incapable of capturing the vagueness and fuzziness during value judgment elicitation. The aim of this paper is to present an evaluation method using a fuzzy ANP (FANP) approach to address this shortcoming. Triangular fuzzy numbers (TFN) and their degree of fuzziness are used in the semantic scale as human judgment expressed in natural language is most often vague and fuzzy. The method employs the alpha-cuts, interval arithmetic and optimism index to transform the fuzzy comparative judgment matrix into set of crisp matrices, and then calculates the desired priorities using the eigenvector method. A numerical example, which was drawn from a real-life case study of an uncontrolled landfill in Japan, is presented to demonstrate the process. Results from the sensitivity analysis describe how the fuzziness in judgment could affect the solution robustness of the prioritization method. The proposed FANP approach therefore could effectively deal with the uncertain judgment inherent in the decision making process and derive the meaningful priorities explicitly from a complex decision structure in the evaluation of contaminated site remedial countermeasures.

    We developed a conceptual feasible design of bioreactor system for treatment of dioxin-contaminated soils that uses the dioxin-degrading fungus Pseudallescheria boydii (P. boydii) we had isolated. The dioxin-degradation conditions in bioreactor treatment was established by clarifying the inhibiting factors for the growth of P. boydii using both real contaminated and laboratory prepared soils mixed with fly ash. In addition, ethanol extraction process as post-treatment methods for the remaining dioxins, and the sterilization conditions of P. boydii, i.e., a weakly pathogenic fungus, in the residue was investigated. The better growth conditions of P. boydii were found to be chloride ion concentration of less than 10 g/L and a pH of less than 9. Under these conditions, 73 10 pg-TEQ/g of the soil was treated to 2860 pg-TEQ/g by the bioreactor process, and the dioxin concentration was further decreased to 580 pg-TEQ/g by ethanol extraction, resulting to total removal ratio of 92%. Furthermore, development of an effective sterilization method for living P. boydii in the residue increased the applicability of our bioreactor system for practical use in dioxin-contaminated sites.

    The aim of this paper is to present an evaluation method to aid decision makers in the prioritization and selection of appropriate countermeasures at the planning stage of site remediation. We introduced a hierarchical network (hiernet) decision structure and applied the Analytic Network Process (ANP) supermatrix approach to measure the relative desirability of the remedial alternatives using the decision maker's value judgment as input. A simplified illustrative example is presented to elucidate the process, as it is being applied to evaluate the feasible remedial countermeasures of a contaminated site caused by uncontrolled landfill. Four decision models derived from the generalized hiernet were examined to describe the effect of hierarchic functional dependence, inner dependence and feedback cycle on the derivation of the priority weights. The ANP could provide a more flexible analytical framework to break down one's judgment through a more elaborate structure in a systematic way to understand the complexity of the decision problem. The proposed method therefore may not only aid in selecting the best alternative but also may help to facilitate communication to understand why an alternative is preferred over the other alternatives through the analysis of the derived weights and its underlying decision structure.

    About 20 million tons of cow manure is generated in Hokkaido, Japan, each year. Approximately 94% of this manure is reported to be recycled. However, the actual amounts of cow manure generated and of manure applied to pastures as compost or soil improver are not entirely clear, and so the reported rates of cow manure recycling are unlikely to represent the realities of current cow manure management. It is possible that excessive amounts of manure are being applied to pastures, leading to nitrate-nitrogen leaching and groundwater pollution. Therefore, it is necessary to assess the mass balance of nitrogen in the system to determine appropriate management strategies for cow manure. In this study, the nitrogen mass balance was calculated for cow manure during all stages of the process, from its generation to its application as a compost or soil improver. The nitrogen mass balance was determined through site investigations. Assuming a typical model of dairy farming, the actual amount of nitrogen applied in pastures was calculated in terms of nitrogen use efficiency, depending on vegetation type. The potential for groundwater pollution was evaluated by numerical simulations based on the nitrogen mass balance. The results showed that when large amounts of manure are applied to pastures, excess nitrogen will be present in the system, which may be susceptible to leaching and lead to groundwater pollution. Methods for cow manure management are discussed based on the results of the numerical simulations. © 201 WIT Press.

    The Japanese government has a strategy for achieving a sustainable society by integrating three societies: low carbon, a sound material-cycle, and natural symbiosis. In particular, biomass utilization is critical for achieving a sustainable society. The utilization of forest residues, which form part of the unused biomass, is expected to occur, and the target utilization ratio of forest residues is > 30% by 2020. However, the current utilization ratio is 1%. It is necessary to clarify the relationship between the utilization of forest residues and the implementation of the three societies above, and to promote the strategic utilization of forest residues, particularly in Hokkaido, as it has abundant forests. Therefore, in this study, the relationship between the utilization of forest residues and the three societies was clarified regarding its effect and limitations according to the Japanese strategy for a sustainable society. Problems in the utilization of forest residues in Hokkaido were then extracted systematically by carrying out a hearing survey of specialists in Hokkaido. Based on the problems encountered, we have developed a feasible system for utilization of forest residues in Hokkaido. © 2012 WIT Press.

    The Analytic Hierarchy Process (AHP) has been used widely in multicriteria selection problems. However, AHP can deal with only a simple hierarchy of elements. On the other hand, the Analytical Network Process (ANP) can deal with more complex structures that have some interdependence or feedback between elements. This study attempted to apply ANP to recycling policy making of organic waste in a region where a large amount of kitchen waste and livestock manure are generated as solid waste. Using the weightings given by interviews with five specialists who are familiar with solid waste management in the region, ANP selected alternatives that included blogasification of kitchen wastes and livestock manure, and it clarified why those alternatives were selected. In addition, a compatibility quotient was proposed as an index to promote a group discussion for the selection of recycling systems. This index was found to be useful for helping to identify the attitude of each decision maker in a group discussion.

    When surveying and diagnosing me contamination of soil and groundwater caused by waste disposal, a number of typical waste-related problems will tend to occur in the initial period. These result from 1) lack of feasibility study (topography, geological conditions, contaminants), 2) diversity of contaminants (chemical and physical properties, subsurface water, and behavior in the environment), and 3) lack of a sense of responsibility in remediation. To solve those problems, it is important to implement a policy, making a purification plan in an early stage of the remediation project, examine the surveying goals in line with an efficient purification plan, and establish the items and index regarding the quantity and quality of required data. With a view to standardizing the survey of soil and groundwater contamination, the authors have proposed a "Contaminant Diagnosis Remediation System([1]) ([2])." By creating a survey chart and a management and operation system of the survey data, based on GIS (Geographic Information System), they suggested efficient survey plan to deal with soil and groundwater contamination by waste, which involves various complex problems.
