“…With studies (Adewuyi, 2020) shows a great dealing in designing a sustainable able for public offices, not much was achieved in the area of labour cost reduction, and time-consuming was practically overwhelming. With the use of the efergy meter, much has been achieved with cost reduction and time-saving when compared with the study (Ugwu et al, 2021).…”

Energy and humanity are superimposed. Its importance to humankind and indispensable nature to the world cannot be overemphasized. Public institutions and households need energy to carry out their daily activities. The increase in the demand for energy in public institutions can be traced to technological advancement, which has resulted in a sharp rise in energy consumption, increasing the energy monthly utility bill astronomically. These have put pressure on public institutions in Nigeria and across the globe, as most are heavily indebted to energy companies. Due to constant electric power failure in Nigeria, public institutions rely heavily on diesel generators to argument their daily energy need. Cost minimization and sustainable clean energy have become a priority for the managers of our public institutions. This study was carried out to establish the exact amount of energy consumption at the Federal Polytechnic Bida, Nigeria, and fashion out ways of reducing the cost burden for the institution.The study was achieved by installing "Efergy Meter" to understudy the energy audit of the institution. Based on the result obtained, the exact amount of energy consumption was established. The solar photovoltaic (P.V.) system was considered a clean and cost-effective option for our public institutions in the long term.

“…The latter requires sorting the various MSW components at the source, carried out at the generation point or disposal facility. For bulky samples, this can be done visually at the source or from the waste truck (Giang, 2017;Ugwu and Ozor, 2021). MSW characterization can be achieved using SowaCLINK software, a computer-based environmental MSW analytical tool developed based on Dulong's model (Sincero and Sincero, 1996).…”

Municipal solid waste constitutes environmental challenges globally, especially in developing countries, due to increasing waste generation, population growth, inadequate infrastructure, lack of data and poor planning. This study aims to conduct a comprehensive waste audit on the municipal solid waste generated in Aba, a metropolis in southeastern Nigeria. Aba is a commercial city considered the messiest because of the massive municipal solid waste generation and poor management. The study investigated the energy potential and waste regeneration. Municipal solid waste data was sought to provide insight into the quantity and composition of municipal solid waste. The methodology was site-based, in line with the standard test method for determining unprocessed municipal solid waste (ASTM-D5231-92) and SowaCLINK software, a computer-based environmental application, was used for characterization. Linear extrapolation was adopted to quantify the rate of municipal solid waste generated. The geometric mean was applied to forecast the area’s population for a 10-year design period. The chemical elements of the characterized municipal solid waste were utilized based on the ASTM-D5291 standard for municipal solid waste thermochemical conversion, and the high and low heating values were analyzed. The outcomes provided energy recovery potential, the electrical power potential, and the power to the grid of electrical power of the municipal solid waste. The results obtained were 0.7813 kg/p/d and 490,268 t/y for a population of 1,719,185 persons. The percentage of the municipal solid waste components with energy potential was 71%, comprising 48% combustible and 23% organic components on average. The high heating value computed was 176.5 MJ/kg, and the low heating value was 14 MJ/kg. The energy recovery potential was 3,709,463 MWh, the electrical power potential was 38,680 MW, and the power to the grid was 26.1 MW daily. The research reveals a promising direction in transitioning from the linear economy of municipal solid waste management toward implementing an integrated sustainable municipal solid waste management based on the circular economy model. The study recommends adopting detailed steps to proffer solutions to the environmental challenges associated with municipal solid waste in most low-middle-income countries to achieve sustainable municipal solid waste management while generating electricity and bio-fertilizers through incineration and anaerobic digestion.

“…In addition, the study's inference that "perceived behavioral control served as a mediator between the relationship of personal norms and waste management behavior" contradicted an earlier conclusion by Muniandy and Anuara (2020) that perceived behavioral control had an insignificant effect on recycling behavior and that the attitude played a mediating role in the relationship between environmental belief and recycling behavior of academicians. Attempts to explain and/or predict the relationship between environmental knowledge and attitude vis-à-vis environmental behavior and action on sanitation and waste management by researchers in Nigeria (e.g., Ugwu, et al, 2021;Bassey & Adekoya, 2021) have equally presented mixed findings as reported in other climes. Hence, further research among Nigerian pre-service teachers is required as done presently.…”

“…Environmental sanitation and waste management are among the most intractable problems of urban centers in less-industrialized countries including Nigeria. Unoccupied lands, roads, waterways, house surroundings, shops and markets in towns and cities are littered with waste while heaps of waste dumps make the urban environments filthy and unsanitary (ACCP, 2019;Ferronato & Torretta, 2019;Ugwu et al, 2021;Pona et al, 2021;UNIDO, 2021;World Bank, 2018). Past efforts at curbing these and other environmentally unfriendly practices appeared ineffective, given the renewed advocacy for environmental literacy (Babalola & Olawuyi, 2021;Jannah et al, 2013;Van Katwijk et al, 2021).…”

Environmentally literate teachers are indispensable to sustainably addressing the challenge of poor sanitation and waste mismanagementin less-industrialized countries. In Nigeria, efforts at stemming the trends of urban waste management problems through stringent environmentalregulations of the military in the 1980s have since yielded ways to programs of information, communication and education embeddedin environmental education under current civilian dispensation. This study analyzed attitudes and dispositions of 125 graduatingpre-service teachers, drawn from a Nigerian public university, towards environmental sanitation and waste management within the contextof environmental literacy (EL). The student-teachers were aware of the adverse effects of unsanitary practices. However, they had not embracedenvironmental sanitation practices as part of daily routines or a way of life. While gender and age were not found to be significantlyrelated to pre-service teachers’ EL knowledge and attitude, subject specialization correlated with knowledge just as family background didwith attitude. The study concluded that the current information-sharing approach is not enough to actualize the action-oriented nature ofEL and calls for curricular review to infuse environmental education (EE) concepts, activities, and methods for addressing the existing gapsin teacher education programs in Nigeria.
