Aluminium is the world’s second most-used metal after steel and the aluminium production industry is the largest, in volume of metal produced, in non-ferrous metal industry. In this study, results of the material flows (country and global scales) related to the production and use of aluminium and energy consumption in 1980 to 2012 were separately analysed. Also, overview of the current status o...

The main purpose of this research is to determine the generation quantity of each generator in a power system. In this way, not only will the electricity demanded by the system be supplied, but the cost of fuel along with the level of pollution can be minimized. Obviously, calculation of the optimal layout of power plants with the aim of minimizing fuel costs and pollutants level contributes to...

Santiago, Chile was subject to serious air quality problems in the late 1980s and early 1990s as a result of increased industrial and transportation emissions. In an effort to improve air quality, the government implemented a number of policies including an emission trading program to reduce and cap emissions of particulate matter smaller than 10 microns (PM10) from stationary sources. The emis...

A simple biofuel production system can be first examined for its policy 8 compliance in terms of GHG emission reduction target relative to fossil-based 9 counterparts. More integrated and optimised biorefinery systems with polygeneration 10 can then be evolved with the aid of graphical analysis of marginal emission savings 11 vs. additional economic margins. This bottom-up approach helps to ach...

Smart Emission is a citizen sensor network using low-cost sensors that enables citizens to gather data about environmental quality, like air quality, noise load, vibrations, light intensities and heat stress. This paper introduces the design and development of the data infrastructure for the Smart Emission initiative and discusses challenges for the future. The Spatial Data Infrastructure (SDI)...

Over the past 10 years, the Chinese State Environmental Protection Administration (SEPA) has actively investigated the potent to use emission trading to reduce sulphur dioxide (SO2 ) emissions from electricity generators and industrial sources. In 1999, SEPA partnered with the U.S. Environmental Protection Agency (U.S. EPA) to cooperate on a study to assess the feasibility of implementing SO2 e...

In the paper the problem of the real-time emission control is discussed, where the air quality forecast is based on the regional-scale model of air pollution transport. The problem formulation utilizes the optimal control technique for distributed parameter systems, which is integrated with the governing equations of air pollution dispersion process. The approach presented in the paper is sulfu...

Coal combustion is the primary anthropogenic source of atmospheric iodine, which has important environmental and health effects. The iodine distribution in Chinese coals and the atmospheric iodine emission factors of coal-fired boilers are studied to estimate the iodine atmospheric flux from coal combustion in China from 1995 to 2009. The national average iodine content weighted by coal yield f...
