Systematically analyzing the problem of heavy metals in the municipal sludge, a meta-analysis of nine metals was undertaken to distinguish the sources and sinks of those with the impact of their accumulation on the environment. Municipal sludge was rich in N, P and K nutrients, was found to...

An increased energy recovery efficiency can be obtained from biomass waste due to coupling hydrothermal carbonation (HTC) with anaerobic digestion (AD). This study focused on optimizing the total energy yield (TEY) from sewage sludge (SS) and pinewood sawdust (PS) in co-HTC-AD coupling process,...

The issue of sludge utilization from wastewater treatment in agriculture is an important socio-economic and environmental problem in the European Union (EU) and Bulgaria. It is becoming topical issue along with constantly growing amount of produced wastewater treatment sludge, deficiency of...

This is a rejoinder to a comment written by Cutler and Miller on our recent paper, "Public Health Efforts and the Decline in Urban Mortality" (IZA DP No. 11773), which reanalyzes data used by Cutler and Miller to investigate the determinants of the urban mortality decline from 1900 to 1936. Two...

This is a rejoinder to a comment by Profs. Cutler and Miller (CM) on a recent paper of ours, “Public Health Efforts and the Decline in Urban Mortality” (NBER WP No. 25027), in which we examine the effect of water filtration on infant and total mortality using the same data as were used by CM...

Privatization of a public good (the management of sewage treatment centers in Dakar, Senegal) leads to an increase in the productivity of downstream sewage dumping companies and a decrease in downstream prices of the services they provide to households. We use the universe of legal dumps of...

Using data on 25 major American cities for the period 1900-1940, we explore the effects of municipal-level public health efforts that were viewed as critical in the fight against food- and water-borne diseases. In addition to studying interventions such as treating sewage and setting strict...

The objective of this paper is a theoretical and empirical analysis and evaluation of the role, importance and opportunities of the water-sewage-sludge industry in the implementation of the circular economy. To realize this objective, a review of both the literature and the EU strategic...

This paper analyses the interdependency of water and energy in India's wastewater sector. Wastewater treatment plants consume a great deal of energy. Energy-efficient technologies are available, but are only spreading slowly in developing countries. In India, only 10% of all wastewater generated...

Despite public approval from the Danish Environmental Protection Agency (Miljøstyrelsen), farmers have proven reluctant to accept wastewater sludge as a source of fertilizer. They are in fact still being paid for accepting it. Based on interviews with key stakeholders, a review of the...

Life Cycle Assessment (LCA) is a technique to assess environmental impacts associated with all the stages of a product's life from cradle to grave. With raising human population and the increasing industrialization, there has been very substantial increase in waste products too. Nowadays the...

Year by year domestic sewage treatment plants are becoming more popular. A pilot solution used on a grand scale in Pietrowice Wielkie commune allowed for the construction of a sewage system for villages located far from each other and made the commune more attractive. This paper presents the...

Water treatment process produces great amount of sludge. According to growing interest in sustainable development and environment protection, sludge management problem should be taken into consideration. Accordingly, its recovery, recycling and reuse are optimal solutions for Water Treatment...

"Forming the 10th volume from this successful international conference series, this book presents the work of scientists, practitioners and other experts regarding recent technological and scientific developments associated with the management of surface and sub-surface water resources."

The environmental Kuznets curve (EKC) could arise from the scale effect in abatement technology as emphasized by Andreoni and Levinson (2001) or from the induced policy response as suggested by Grossman and Krueger (1995). This paper incorporates these two contrary views into a model and...

Environmental pollution is a serious problem in highly industrialized countries, as it may pose a threat to the human health and life. For these reasons, entities responsible for polluting the environment and its natural resources undertake pro-environmental actions that involve reduction of the...
