“…Troncoso et al [29] note that businesses need an implementation strategy that targets different adopter behaviours, as well as a long-term vision. Additionally, in a study focusing on the assessment of bioenergy alternatives in Uganda, Okello et al [16] found that the adoption rate of bioenergy technologies can potentially increase if policies can make it more affordable.…”

“…Buchholz et al [15] addressed a multidimensional approach to assess the different contexts in which sustainable bioenergy systems are embedded. To utilise the full potential of biomass residues, additional research is required that should, according to Okello et al [16], address the technological, economic, and social dimensions that increase the adoption of innovation within social systems. Fri and Savitz [5] stress that the movement through different stages of diffusion is not linear and requires complex feedback loops.…”

a b s t r a c tWith diffusion theory as the point of departure, this study analyses the factors that influence the adoption of renewable electricity from individual households' perspectives. The analysis is based on a case study provided by a Swedish energy service company operating in rural Uganda. The company distributes electricity to rural households via a mini-grid powered by a biomass gasification system. Three critical dimensions are identified to be crucial for adoption: technical, economic, and social. First, there is an emphasis on the relative advantages of the new technology. Second, there are economic requirements regarding a viable financial system for adopters, especially in such a low-income market. Third, the social dimension is critical, particularly the importance of foreign firms collaborating with local actors. We further suggest that a lack of understanding of local communities can lead foreign companies to fail in diffusion attempts. While we focus on Uganda, the results of our research are highly relevant for foreign actors who attempt to penetrate rural markets in developing countries in general.

“…The resulting product is called briquettes and is easier to handle and has better combustion properties than the original biomass material. In Uganda, the available agricultural and forest residues could be used as raw material for briquetting [44,45]. In the proposed system, the briquettes are used for cooking in gasifier stoves that are more efficient than traditional stoves [45].…”

Appraising Bioenergy Alternatives in Uganda Using Strengths, Weaknesses, Opportunities and Threats (SWOT)-Analytical Hierarchy Process (AHP) and a Desirability Functions Approach

Poor access to clean and reliable energy technologies is a major challenge to most developing countries. The decision to introduce new technologies is often faced by low adoption rates or even public opposition. In addition, the data required for effective decision making is often inadequate or even lacking, thus constraining the planning process. In this study, a methodology for participatory appraisal of technologies, integrating desirability functions to the strengths, weaknesses, opportunities and threats (SWOT)-analytical hierarchy process (AHP) methodology was developed. Application of the methodology was illustrated with an example for participatory appraisal of four bioenergy technologies in Uganda. Results showed that the methodology is effective in evaluating stakeholder preferences for bioenergy technologies. It showed a high potential to be used to identify and rate factors that stakeholders take into consideration when selecting bioenergy systems. The method could be used as a tool for technology screening, or reaching consensus in a participatory setup in a transparent manner.

“…Woody biomass resources can be found in all countries and many fields, (Lakó et al 2008), such as forestry, agricultural, and marine (Plištil et al 2005), and it can be used for fuel in developing or developed countries (Lundborg 1998;Prasertsan and Sajakulnukit 2006;Jehlickova and Morris 2007;Gavrilescu 2008;Kazagic and Smajevic 2009;Okello et al 2013;Vilcek 2013), separately or when mixed with coal (Kostanaki and Vamvuka 2005). The European Union (EU) uses about 41.3% of the area, (4 million km 2 ) of its total land (10 million km 2 ) for agriculture and 3 million km 2 for forestry.…”

This study was done to determine the effects of beech sawdust torrefaction on pellets obtained in the laboratory. Torrefied beech (Fagus sylvatica L.) sawdust was used to make pellets. This species was chosen based on the existence of a market for such micro-briquettes. Rigorous comparisons between torrefied and non-torrefied pellets were conducted. It was found that treating the sawdust had both beneficial and non-beneficial effects, but the total effect is positive. Economical elements were also considered, emphasizing the use of wood biomass as fuel. Theoretical and experimental aspects are taken into consideration, the experimental results being used to validate the theoretical model. The experiments performed demonstrate that heat treatment can add value if it meets certain parameters, such as a maximum temperature of 260 °C for 5 min. Heat treatment of beech sawdust in the form of pellets or briquettes was shown to be a simple, viable, effective treatment because the heating process improves the calorific value and other relevant properties of the torrefied sawdust.
