This study aims to quantify water appropriation and the potential production of algal bio-oil using freshwater and municipal wastewater effluent (MWW) as an alternative water resource. The county-level analysis focuses on open-pond algae cultivation systems located in 17 states in the southern United States. Several scenarios were developed to examine the water availability for algae bio-oil pr...

Waste-to-energy (WtE) facilities have been established worldwide as a sustainable method for the disposal of residual waste. In the present study the following competing WtE systems were compared: (1) municipal solid waste incinerators (MSWIs) with energy recovery; (2) co-incineration of waste in old lignite or coal-fired power plants; (3) substitute [refuse-derived fuel (RDF)] incinerators wit...

As one of the countries with large amounts of dioxin releases, the control of dioxins is a major challenge for China. Municipal solid waste (MSW) incineration should be considered a high priority source of dioxin emissions because it is playing an increasingly more important role in waste management. MSW incineration in China has much higher emission rates of dioxins than in the developed count...

This work investigated the characteristics of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F) in stack-flue gases from six stationary emission sources in five types of incinerators: industrial waste incinerator (IWI), small-scale municipal solid waste incinerator (MSWI), medical waste incinerator (MWI), cement kilns (CK), and crematories (CR). These characteristics were further inv...

Thermal treatment is an interesting strategy to dispose of municipal solid waste: it reduces the volume and weight of the material dumped in landfills and generates alternative energy. However, the process emits pollutants, such as dioxins and furans. The present study evaluated MSW gasification-combustion integrated technologies in terms of dioxin and furan emission; and compared the obtained ...

With the growing concern regarding emission of volatile organic compounds (VOCs) from wastewater treatment plants (WWTPs), the relationship between the VOC emission rates and the associated public health risks has been rarely discussed. The objective of this study was to examine and compare the VOC emission rates and cancer and non-cancer risks by inhalation intake, using a municipal WWTP in Ch...

Wireless broadband initiatives for cities are receiving significant attention today. However, while some major cities have already announced citywide wireless networks, the market for municipal wireless broadband is still in the early stages. Most of these large networks will almost certainly experience numerous changes before they are fully deployed. Most of the existing municipal wireless net...

This paper proposes a discussion concerning the use of social media-related geographic information in the context of the strategic environmental assessment (SEA) of Sardinian Municipal masterplans (MMPs). We show that this kind of information improves, substantially, the SEA process since it provides planners, evaluators, and the local communities with information retrieved from social media th...

Many U.S. metro cities’ municipal wireless projects have been delayed or canceled. Cost forecasting, market penetration rates, and changing technologies are factors that contribute launch failure. Although larger cities have tried, smaller towns are more successful due to the lack of commercial competition. This paper takes the issues of price, cost, and market share of WiFi municipal wireless ...

Background: Municipal waste incineration are one of the largest resources of 2,3,7,8- tetrachlorodibenzo-pdioxins (TCDDs) and Polychlorinated dibenzofurans (PCDFs) from incineration ends up in water and food cycle are taken up by fish and etc. These gaseous emission products tend to give rise to concern due to their carcinogenic potential, as well as their potential adverse health effects on re...
