    Role of energy resources to production output in cement organizations in Tanzania: Evidence from selected energy resources
    (International Journal of Economics, Business and Management Research, 2020) Sugnau, Joseph; Mandara, Isack
    In a country, energy is an important resource to be considered for the development of the Nation. The total country's energy consumption determines the level of development of a nation. Countries and organisations should be provided with empirical evidence on how energy resources affect production output. However, little has been researched in this area to explain the effect of energy resources on production output. Therefore, this paper aimed to determine the role of energy resources to production output in cement organizations. The study was conducted in Tanzania and used time series data for ten (10) years, from year 2005 to year 2014. To assess the effect of energy resource on production output, the study used multiple linear regression model to analyze the data. From the findings of the study, it was revealed that energy resources have positive and significant effect on production output in cement organizations. Being the case, cement organizations should consider energy resources as a key and important resource in the production of cement.

    Social life cycle assessment in solar dryer house for postharvest loss management technology: Application of UNEP / SETAC in Tanzania
    (Arabian Journal of Business and Management Review (Kuwait Chapter), 2024) Sungau, Joseph; Mkuna, Eliaza; Abeid, Ashiraf; Lyakurwa, Felichesmi; Manouchehr, Shokri
    Social Life Cycle Assessment is inherently an extension of sustainability assessment that is limited to environmental and economic pillars. Social life cycle assessment (S-LCA) on the other hand is a methodology used to cover the social aspects of sustainability. This article integrates three pillars of sustainability; economy, environment and society on Solar Dryer House technology for reduction of post-harvest losses. The purpose of the article is to examine the extent of sustainability of Solar Dryer House technology by exploring the environmental, economic and social pillars. A textual analysis was undertaken on United Nations Environment Program/Society for Environmental Toxicology and Chemistry (UNEP-SETAC) Life Cycle Initiative to examine the social life cycle assessment of SDH manufacturing technology on major categories of producers, workers, distributors, consumers. Analysis of social indicators were developed with the scoring system to describe the potential positive and negative social impacts on related stakeholders within life cycle stages. Lack of clarity in conceptualizing of UNEP-SETAC Life Cycle Initiative to examine the social life cycle assessment of SDH manufacturing technology limit the application of sustainability assessment on manufacturing technologies in Tanzania. Social Life Cycle Assessment supports social and labour policies as well as Sustainable Development Goal 8 which entails that people should have jobs that pay decently to support their livelihoods while other social welfare aspects and labour rights are considered. Manufacturing technologies that adhere to S-LCA principles guarantee sustainability.
