Production of solid fuels from wooden biomass is defined with appropriate energy chain of supply. The notion of energy chain concept has been defined as the trajectory of energy transformations from the fuel source or energy sources to useful energy form to end users. Supply chain for production solid fuels from wooden biomass is also energy chain with high importance in biomass energy planning. In this paper, base for testing and research is developed mathematical model in previous published paper with preliminary note titled as “Multi-Criteria Optimization Concept for the Selection of Optimal Solid Fuels Supply Chain from Wooden Biomass“ at Croatian Journal of Forest Engineering. Three supply chains have been included in comparison: production of wood chips at the terminal – variant 1, production of pellet – variant 2 and production of wood chips by means of a mobile chipper in a forest – variant 3. The VIKOR methodology is used for total ranking all mentioned chains. Real input data have been used for mathematical calculation correspond to Bosnia and Herzegovina conditions.

The delivery of biomass products from the production place to the point of final use is of fundamental importance within the constitution of energy chains based on biomass use as renewable energy source. In fact, transport can be one of the most economically expensive operations of the entire biomass energy production process. In this work, a geographic identification, through remote sensing and photo-interpretation, of the different biomass sources was used to estimate the potential available biomass for energy in a small-scale supply chain. The economic sustainability of transport costs was calculated for different types of biomass sources available close to a biomass power plant of a small-scale energy supply chain, in central Italy. The proposed analysis allows us to highlight and visualize on the map the areas of the territory characterized by greater economic sustainability in terms of lower transport costs of residual agroforestry biomass from the collection point to the final point identified with the biomass power plant. The higher transport cost was around € 40 Mg−1, compared to the lowest of € 12 Mg−1.

Determining Factor

The use of biomass energy is increasingly widespread among industries. There is a growing demand for the purchase of biomass aiming at the generation of thermal and electric energy, as in the case of the sugar and energy sectors, pulp and paper and wood panels. The aim of this article is to analyze a biomass supply chain considering the offer, distance and energy characteristics of biomass. The demand for biofuel is from a panel industry located in the Metropolitan Region of Sorocaba. The final cost was calculated based on price quotes, freights and energy properties of each biomass. The biomasses chosen for analysis were: sawdust, wood chips, briquettes, firewood, standing eucalyptus forest (log) and rice husks. It was found that the largest supply of biomass at the lowest cost is in the distances between 50 km and 250 km. The best materials were wood chips and eucalyptus log. Freight was not a determining factor in the final cost of biomass, even for the longest distances. It was concluded that the chip and the log had advantages for different distances.

The delivery of biomass products from the production place to the point of final transformation is of fundamental importance within the constitution of energy chains based on biomass use as a renewable energy source. Transport can be one of the most economically expensive operations of the entire biomass energy production process, which limits choices in this sector, often inhibiting any expansive trends. A geographic identification, through remote sensing and photo-interpretation, of the different biomass sources was used to estimate the potential available biomass for energy in a small-scale supply chain. This study reports on the sustainability of transport costs calculated for different types of biomass sources available close a biomass power plant of a small-scale energy supply chain, located in central Italy. To calculate the transport cost referred to the identified areas we used the maximum travel time parameter. The proposed analysis allows us to highlight and visualize on the map the areas of the territory characterized by greater economic sustainability in terms of lower transport costs of residual agroforestry biomass from the collection point to the final point identified with the biomass power plant. The higher transport cost was around €40 Mg−1, compared to the lowest of €12 Mg−1.

Health And Safety Risks

Alternative solid fuels becoming popular thanks to considerable fuel cost save (comparing to gas). Pellet quality varies depending on content of bark, straw and other non-wood additives. These additives decrease the combustion efficiency and increase the fuel consumption and solid emission. Pellets stored in large amount bring certain hazard for a man. They may become dangerous for the high fire risk due to self-ignition tendency and also due to moulds presence attacking the human breath system.

Operational Structure

Abstract The process of Outsourcing Logistics Service (OLS) is deemed incipient in the management of organizations, not only because of the operational problems it presents, but also of its difficulties fitting into the company’s overall strategy. The present theoretical study, building on the resource-based view of the firm, aims to propose a framework that guides managers in developing strategies to OLS starting from the operational structure to establish the necessary resources, capabilities, and routines. In addition, taken into account is the importance of analyzing risks and resilience in the environment, concomitantly with the analysis of the operational structure. Thus, four questions were developed, aimed at leading operations managers to reflect on the development of the strategy. The framework proposed for OLS considers the supply chain management department as the main interlocutor of the strategy. This framework can be adapted according with the necessity of the contracting company, and its main intention is to enable the establishment of a project that contemplates the necessary resources, the capabilities (criteria), and the operational routines (subcriteria) for the selection of a logistics service provider in the market, one which truly addresses the needs of the organization. This framework is already intrinsic in the practical actions of the authors, because of their extensive advisory activity over the last five years in OLS to logistics service provider. In addition, it is worth mentioning that so far in the tacit applications of this framework there has been no application similar to another.

Abstract Background: In Ethiopia, about 92.3% of all the biomass energy is consumed by domestic households and the demand is growing from 10-14%. However, there are little/no practical experiences or documented indigenous knowledge on how traditional people identify and select high biomass producing plant species with short rotation periods at Boset District. Therefore, the present study was aimed at: (1) selecting and documenting high biomass energy producing plant species at Boset District; (2) identifying major predictor variables that influence the prioritization and selection of species; and (3) develop a Generalized Linear Model (GLM) to predict the selection of species. Methods: A total of 96 informants comprising 59 men and 37 women between the ages of 18 and 81 were sampled. Data were collected using structured interviews, guided field walk, discussions and field observations. Results: Collected data indicated that 88.5% of the informants involved in firewood collection, while 90% practiced charcoal making. A total of 1533.60 Birr per household on average was earned annually from this activity. A total of 25 firewood and/or charcoal plant species were identified and documented at Boset District. Of these, Acacia senegal, Acacia tortilis and Acacia robusta were the three best prioritized and selected indigenous high biomass producing species. Prosopis juliflora, Parthenium hysterophorus, Azadirachta indica, Calotropis procera, Cryptostegia grandiflora, Lantana camara and Senna occidentalis further grouped under introduced fuelwood species. Prediction of GLM assured sampled Kebeles and source of income generated from fuelwood species positively and significantly (p<0.001) related to selection of species. Higher efficiency to provide energy and heat; little or no smoke or soot; easier to cut and split the wood and easier availability were some of the main selection criteria. Conclusions: This study provides valuable information in selection and documenting of high biomass producing plant species for proper management and sustainable use at Boset District. The three most selected species (A. senegal, A. tortilis and A. robusta) should be further evaluated at laboratory to determine their energy values.
