UNLABELLED Source-separating urine from other domestic wastewaters promotes a more sustainable municipal wastewater treatment system. This study investigated the feasibility and potential issues of applying a urine source-separation system in tropical urban settings. The results showed that source-separated urine underwent rapid urea-hydrolysis (ureolysis) at temperatures between 34-40 degrees ...

Bhutan lacks the solid waste data which are essential parameters for planning and scheduling of municipal solid waste management (MSWM) systems. The first ever large-scale research survey on solid waste generation and characterization in the urban areas of Bhutan was conducted between November 2007 and January 2008 using the method of waste sampling at source. The MSW generation rates in the ur...

6.2.1 The traditional role of municipal bodies had been one of providing basic amenities of civic life. Services such as water supply and sanitation, roads and drains, street-lights, collection and disposal of solid waste, maintenance of public places, burial grounds and crematoria, cattle pounds, registration of births and deaths, maintenance of markets have long been seen as the function of m...

The trend towards redevelopment or re-profiling direction greening increasing comfort living population is becoming more significant. These changes have become popular a number large cities Russia due to huge rate urbanization movement from...

Source contributions to ambient PM10 (particles with an aerodynamic diameter of 10μm or less) in Beijing, China were determined with positive matrix factorization (PMF) based on ambient PM10 composition data including concentrations of organic carbon (OC), elemental carbon (EC), ions and metal elements, which were simultaneously obtained at six sites through January, April, July and October in ...

This paper investigates possible solutions to the problem of urban orthophotography. Extensive work has been carried out to attain the best possible results, using all the existing software in the Department of Geomatic Engineering, University College London. Two of the most promising methods, which yield the best results, are analysed further. New routines were written in C language, as additi...

FOR MANY YEARS, poverty in urban areas of Africa, Asia, Latin America and the Caribbean has been identified by spatial area (e.g. settlement, neighbourhood, inner city) as often as it has been referred to by social group (e.g. low-income women, the homeless). This has perhaps given inadequate recognition to poverty differentiation within urban poor groups or, to put it another way, it has contr...

Ambient air pollution in urban and industrial areas in Greece was a serious environmental problem which was connected with rapid urbanization of cities, anarchic housing development without basic infrastructures and increases of motor vehicle fleet in urban regions. Especially Athens, witnessed severe air pollution problems in the decades 1960s‘-1970s‘ and the formation of the infamous brown-ye...

Air pollution experienced by expanding urban areas is responsible for serious health effects and death for millions of people every year. Trash burning is a common disposal method in poor areas, yet it is uncontrolled in many countries, and its contribution to air pollution is unclear due to uncertainties in its emissions. Here we develop a new trash burning emission inventory for Mexico City b...
