Pilot and prototyping scale investigations were undertaken in order to evaluate the technical feasibility of producing value-added biopolymers (polyhydroxyalkanoates (PHAs)) as a by-product to essential services of wastewater treatment and environmental protection. A commonly asked question concerns PHA quality that may be expected from surplus biomass produced during biological treatment for water quality improvement. This paper summarizes the findings from a collection of investigations. Alongside the summarized technical efforts, attention has been paid to the social and economic networks. Such networks are needed in order to nurture circular economies that would drive value chains in renewable resource processing from contaminated water amelioration into renewable value-added bioplastic products and services. We find commercial promise in the polymer quality and in the process technical feasibility. The next challenge ahead does not reside so much any more in fundamental research and development of the technology but, rather, in social-economic steps that will be necessary to realize first demonstration scale polymer production activities. It is a material supply that will stimulate niche business opportunities that can grow and stimulate technology pull with benefit of real life material product market combinations.

Emerging technologies, including nanotechnologies, affect the social, economic, and environmental dimensions of our world, often in ways that are entirely unanticipated. There is considerable effort underway to explore uses of nanomaterials in applications such as membrane separations, catalysis, adsorption, and analysis with the goal of better protecting environmental quality. Along with the growth of a nanochemistry industry there is also the need to consider impacts of nanomaterials on environment and human health.

Quantitative Indicators

Social impact as growing concern is becoming an important aspect of the design and operation of wastewater treatment processes. A need has arisen for the development of quantitative indicators of social sustainability. Design and operation of wastewater treatment processes additionally require simple and effective methods to represent and understand the interconnections between the indicators of social sustainability. This paper presents an approach for the development of quantitative social sustainability indicators, and introduces a novel method for defining and visualizing indicator interdependence. It outlines equations for quantitative evaluation of health, safety and security, and comfort. Weighting method of the bipartite network of the relations between the indicators and stakeholders enables clear visualization of the interdependencies of the indicators and facilitates simplification of the set of social sustainability criteria. It creates a basis for reduction of amount of data needed for performing the analysis and reducing the social sustainability assessment’s costs.

Conventional wastewater treatment systems are expensive in either investment or running costs. On the other hand, waste stabilisation ponds may be unable to meet effluent standards for nutrients. Wastewater treatment using duckweed therefore becomes more significant as an option capable of achieving effluent standards and generating revenue from selling the duckweed. However existing duckweed based wastewater treatment (DWWT) systems have high land requirements despite being able to reduce concentrations of organic compounds and pathogens to acceptable levels. Improved guidelines for the design of DWWT are necessary to obtain a reliable and cost-effective wastewater treatment plant using duckweed. This guideline provides a DWWT design program using spreadsheets for different configurations of wastewater treatment units using duckweed. The design program developed suggests that a combination of anaerobic ponds, DWWT systems and maturation ponds can minimise land requirements and capital costs while achieving specified effluent standards. In order to achieve effluent standards, the land required is typically from 1.5 to 1.8 m2/capita (excluding associated facilities), capital costs are in the range from 7.9 to 9.7 USD/capita, with a retention time from 15 to 18 days. Income generation is dependent mainly on the social and cultural acceptability of duckweed use within the community.

Analysis Models

The environmental, economic, and social dimensions of sustainability, were connected in a systems ecology model with focus on wastewater treatment. Life Cycle Assessment and similar approaches are the most common systems analysis models in the wastewater treatment context. These models are beneficial, but are not the only possible approach to systems analysis. The model in this paper showed that the social and economic dimensions were inseparable intertwined, and both of them dependent on the environmental dimension for ecosystem services in the form of natural resources and regenerating capacity. The holistic view, as applied by a systems ecology approach, put focus on how sustainable wastewater treatment are limited to deliver something that can be assimilated by the environmental systems, and in the best applications, produce something that is again useful to the society

The purpose of the investigation was to examine the reason for the relative age shift in the incidence of diphtheria. The disease has been represented as now concentrating on children of school ages. We analysed, for various quinquennial periods beginning with 1901–5, the statistics of the notifications and deaths according to age and sex in the London boroughs which we classified into four social classes where I to IV represented descending order in the social scale. The conclusions arrived at were:I. The age shift as represented by the ratio of the mortality at ages 0–4 to ages 5–9 years which has taken place in London has been found to occur mainly in the poorer districts. The ratio in the residential districts has not altered appreciably during the thirty years under review (Table V).II. The age shift is also indicated by the morbidity statistics for the three quinquennial periods, 1901–5, 1909–13 and 1919–23, as there was a significant increase in the mean age of attack of children under 15 years of age.The case rate at ages 5–14 during 1929–33 as compared with that in 1901–5 has increased most amongst children in the lowest social group.III. Each of the variables (a) the decrease in the birth-rate between 1911 and 1931 in each London borough—an index of the change in the size of family—and (b) the decrease in infant mortality—a measurement of environmental improvement—is positively and significantly correlated with (c) the corresponding change in the size of the ratio of the case rates at ages 0–4 to 5–9 years. The coefficients were:but the partial correlation coefficientsindicate that the change in the size of family is the more important factor as the value of rac.b is fairly large and significant, whereas the correlation between the change in the ratio and the environmental improvement when the effects of the decreasing birth-rate are made constant—rbc.a—becomes statistically unimportant.

Abstract Background The social impacts generated by industrial waste treatment processes have not been studied enough, as shown in the literature. Social life cycle assessment studies have mainly focused on the assessment of products and less on industrial waste, especially wastewater, although potentially relevant from an environmental point of view, and also from a social one for various stakeholders. Purpose This case study concerns the social assessment of an innovative technology to treat the wastewater of a microelectronics company. In order to produce electronic components and semiconductors, the company has to treat and dispose of relevant wastewater streams containing various toxic substances. The wastewater streams need to be treated in order to protect the eco-system, representing a high cost for the company and a potential impact on the environment. For this reason, the company developed a LIFE project to demonstrate the viability to decrease the burdens on water bodies. The positive outcome of the test on the pilot plant paved the way for the construction of the full-scale plant that will treat all the wastewater generated by the company. The objective of this paper is the socio-economic assessment of a full-scale plant designed to treat three different kinds of wastewater. Methods The assessment of socio-economic potential impacts of a new technology has been carried out through the PSILCA (Product Social Impact Life Cycle Assessment) database implementation to evaluate 65 social indicators of a wastewater treatment plant. Results The line with the highest impact is the one which treats tetramethylammonium hydroxide; this is because this wastewater flow is the most abundant (14 and 43 times greater than the other wastewaters, respectively). The most affected stakeholder is the Local Community, followed by the Actors of the Value Chain; in fact, the results referred to the functional unit considered exceed 300,000 medium risk hours in both cases. For the Local Community this result arises from the indicator “Contribution to environmental load,” which is understandable considering the object of the study since this indicator includes health effects. As far as the Value Chain Actors stakeholder is concerned, the two indicators most impacted are “Corruption” and “Social responsibility along the supply chain”. The analysis conducted has also shown that upstream has a fundamental relevance for the social risks detected. Conclusions Considering the current lack of studies on both environmental and social impacts of wastewater treatment, and the fact that Social Life Cycle Assessment has not been widely used in this field, as emerged from literature review, this work is the first use of the PSILCA database to assess an industrial wastewater plant. The use of a social life cycle assessment database allows the value chain of a product system to be considered: the results show that most of the overall social risk derives from upstream sectors.

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.
