Abstract: The Methodist University of São Paulo, a confessional institution with three campuses in São Bernardo do Campo, in the São Paulo Metropolitan Region, which has 1,600 employees and 25,000 undergraduate students and postgraduate students, adopted in 2008 Sustainability as a transversal theme in its Institutional Educational Project. In 2009, started the Methodist Sustainable Program with the goal to mainstream sustainability in all undergraduate programs, in a co-creative process that included staff, professors and directors. Theory U and other similar methodologies were used in order to connect with new perspectives and attitudes that could arouse a co-creation field and a process able to reveal the connections of all expertises and knowledge produced with the sustainability area. The expectation is that this methodology continues to expand, involving university sectors and participants and oriented by educational purposes, research and community outreach. The expansion of the program led to the development of Actions Research Projects as reported in the present work, designed to consolidate a network of regional solidarity economy. The experiment enrolled 12 professors and lecturers, 20 students and 11 social enterprises linked with Solidarity Economy Network of the populous neighborhood of Montanhão in São Bernardo do Campo, Brazil. The development of the project and the results accomplished created concrete actions of the University that benefit peripheral areas of the Metropolitan Region of São Paulo and could be used for promoting emergence and organization of individual and collective enterprises in other six nearby cities, that together with São Bernardo do Campo forms the Great ABC region, home to 2,500,000 inhabitants. Collective training of entrepreneurs in technology, human reasoning and political citizenship in the urban world were the axis of project. The results obtained can engage other groups and nearby cities, strengthening the social consciousness and regional identity.

Abstract: However, the design, control, and optimization of the hybrid systems are usually very complex tasks; the stand-alone hybrid solar–diesel power generation system is recognized generally more suitable than systems that only have one energy source for supply of electricity to off-grid applications. A proposed PV system has been designed and optimized using HOMER software computer model to supply a potato cooled store in Kirkuk city in Iraq. The result obtained from the optimization gives the cost of energy (COE) is 0.639 US$/kWh with 2axis trucking system and 0.692 US$/kWh with no trucking system. Energy cost is 0.796 US$/kWh when the load is supplied by the diesel generator alone.

Abstract: The economic and ecological problems associated with fossil fuel have raised interest in biofuel research in recent times in different parts of the world. The use of Eucalyptus forest waste biomass with no appreciable value to industries or for food as alternative and cost effective feedstock for bioethanol production was evaluated in this study. E. camaldulensis biomass (bark and leaves) were pretreated separately with acid (2M H2SO4) and Microwave irradiation (250V, 50Hz) prior to fermentation with Bacillus subtilis and Escherichia coli isolated from surrounding soil. Higher yield of reducing sugar were obtained from bark (43 %) and leaves (38.5 %) pretreated by microwave irradiation as compared with acid treated plant biomass. Similarly, Bioethanol volume and concentration of 34.89 g/l and 0.51 % respectively were higher in Microwave irradiated bark of E. camaldulensis at 21 days of fermentation when E. coli and B. subtilis were used in synergy The least bioethanol volume yield of 18.79 g/l and concentration of 0.12 % when bark and leaves of E. camaldulensis were combined was obtained on day 7 of fermentation using E. coli. The study concludes that the amount of dried wastes generated (37.8 kg) from one average stand of Eucalyptus tree could yield significant volume (131,884.2 g/l) of bioethanol when B. subtilis and E. coli are used in synergy.

Abstract: In this study,the global solar radiation over the southern coastal region of Bangladesh is estimated from the duration of relative sunshine hours. Five models are considered to estimate the solar irradiance. These models are modified form of classical Angstrom – Prescott regression equation. A quadratic logarithmic model, relating the relative solar radiation and the relative sunshine hours is proposed for southern coastal region of Bangladesh. NASA Surface Meteorology and Solar Energy (SSE)have record of solar radiation data all over the world, measured from satellite. As Bangladesh Meteorological Department or any other organization has no record of measured solar radiation data for the considered locations, the estimated solar irradiance from the proposed regression model is compared with the data recorded by NASA SSE. Also t – statistics is applied to the estimated results to determine whether or not they are statistically significant at a particular confidence level.

Abstract: The paper introduces and develops a green public procurement practices (GPPP) analytical framework for the Ghanaian Public Sector involving six major practices including Acquisition and Material Specification Planning, Environmental Requirements, Green Purchasing, Strategic Supplier Partnership, Green Information & Communication Technology, and Employee Training. The study involved five Polytechnics in Ghana selected using random sampling and ten public procurement professionals from the five selected Polytechnics using a hybrid of convenient and purposeful sampling techniques. The data for the study was obtained using questionnaires and interviews techniques. A grey-based DEMATEL technique, a multi-criteria decision-making (MCDM) tool,was utilized to help identify the most influential major practice and important sub-practice in terms of the overall goal of achieving green economy. The MCDM tool revealed that ‘Strategic Supplier Partnership’ is the most influential major practice whilst ‘Review of Material needs to include Green Procurement Requirements’ was identified as the most important sub-practice. For the first time, a MCDM tool is utilized to identify the most influential and important GPPP for implementation in Ghanaian public sector. Finally, the paper will allow public sector procurement professionals to make thoughtful decisions on products and service purchases with a focus on environmental and societal consequences to achieve sustainable development.
