AbstractThis chapter’s target is to accentuate on the benefits for the social-economic development, resulting from the wastewater governance. The wastewater treatment is the process of extraction of extra-resources, namely: residual biogas, used for heat and electricity; sand used in the construction; sludge and purified water, discharged into hydro-basins. Simultaneously, attention should be paid of the environmental challenges in relation to the circular economy. The sludge use should become a national policy with a direct governmental engagement, having in view that wastewater treatment plants and wastewater safety are strategic guidelines. Statistical information was used by Eurostat and the Ministry of Agriculture and Food and Forestry (MAFF)’s Agristatistics Department (2020). A brief literature review of publications on the topic is made at the outset. Thereafter, more light is placed on the regulatory framework in the EU and Bulgaria. The analysis continues with the situation so far, based on existing statistics on the quantities of sludge received and its utilization in agriculture in the European countries and in Bulgaria. Dependence and sludge effect on grain yield are determined on the basis of regression analysis.

Water reuse and recycling is gaining momentum as a way to improve the circularity of cities, while recognizing the central role of water within a circular economy (CE) context. However, such interventions often depend on the location of wastewater treatment plants and the treatment technologies installed in their premises, while relying on an expensive piped network to ensure that treated wastewater gets transported from the treatment plant to the point of demand. Thus, the penetration level of treated wastewater as a source of non-potable supply in dense urban environments is limited. This paper focuses on the demonstration of a sewer mining (SM) unit as a source of treated wastewater, as part of a larger and more holistic configuration that examines all three ‘streams’ associated with water in CE: water, energy and materials. The application area is the Athens Plant Nursery, in the (water stressed) city of Athens, Greece. SM technology is in fact a mobile wastewater treatment unit in containers able to extract wastewater from local sewers, treat it directly and reuse at the point of demand even in urban environments with limited space. The unit consists of a membrane bioreactor unit (MBR) and a UV disinfection unit and produces high quality reclaimed water for irrigation and also for aquifer recharge during the winter. Furthermore, a short overview of the integrated nutrient and energy recovery subsystem is presented in order to conceptualise the holistic approach and circularity of the whole configuration. The SM technology demonstrates flexibility, scalability and replicability, which are important characteristics for innovation uptake within the emerging CE context and market.

The Impact

Although significant progress has been achieved in the field of environmental impact assessment in many engineering disciplines, the impact of wastewater treatment plants has not yet been well integrated. In light of this remarkable scientific progress, the outputs of the plants as treated water and clean sludge have become potential sources of irrigation and energy, not a waste. The aim of this study is to assess the environmental impacts of upgrading the wastewater treatment plants from primary to secondary treatment. The Lifecycle Assessment Framework (ISO 14040 and 14044) was applied using GaBi Software. Abu Rawash wastewater treatment plant (WWTP) has been taken as a case study. Two scenarios were studied, Scenario 1 is the current situation of the WWTP using the primary treatment units and Scenario 2 is upgrading the WWTP by adding secondary treatment units. The study highlighted the influence and cumulative impact of upgrading all the primary WWTPs in Egypt to secondary treatment. With the high amount of energy consumed in the aeration process, energy recovery methods were proposed to boost the circular economy concept in Abu Rawash WWTP in order to achieve optimal results from environmental and economic perspectives.

Annotation. In the article, the authors first proposed a comprehensive model for assessing and predicting the indicators of sustainable socio-ecological and economic development of the Republic of Kazakhstan. These aspects are system forming in the activities of any state in the development of programs and strategic documents. The main objective of which is to ensure the social well-being of the population, which is impossible without economic development and ensuring the reproduction, process as well as maintaining environmental standards. Based on the correlation-regression analysis a system of econometric equations describing the relationship of the main indicators of the development of the economic, social and environmental spheres and various factors, respectively, explaining the changes in these spheres had compiled.

Energy access plays a crucial role in enhancing the social-economic development among the household members in any nation. Notwithstanding the role of energy access in improving the livelihood of people, the problem of energy access has revealed to be more serious in rural areas of Tanzania. The increased in problem of energy access in rural areas of the developing countries is due to the absence of a unified set of indicators for measuring the energy access to rural households from developing countries including Tanzania. This study therefore, aimed at determining the indicators of energy access in rural areas of Tanzania.The study employed Cross- sectional type of the research design to collect data from 384 heads of household from the rural areas of Njombe and Iringa regions in Tanzania. Moreover, the Quantitative Exploratory Factor Analysis using Principal Component analysis and varimax method was employed to determine the indicators of energy access. The identified indicators using exploratory Factor Analysis was further confirmed using Confirmatory Factor Analysis. The study findings revealed that, the indicators for measuring the provision of energy access to rural households in developing countries including Tanzania ranked based on its importance are: availability, affordability, durability, efficient, no production of smokes, easy to use and ability to keep cooking facilities clean.Based on these findings, the study concludes that, indicators of energy access are important in enhancing the social economic development and improvement of the livelihood of people in rural areas. In the light of this conclusion the study recommends to government energy experts and other practitioners of to use the identified indictors when measuring energy access to rural households in Tanzania in order to improve the livelihood and their standard of living.
