In this second period, energy consumption of industry sector has decreased by more than a quarter with respect to 2003, with the greatest decreases by non-metallurgic minerals (−31.5 %) and chemical and petrochemical (−30.2 %).
Heat integration is essential for reducing the energy consumption of process industries.
However, in order to simplify the calculation process, we assume that the water consumption structures of various industrial departments of Beijing in 2020 and 2010 are identical; thus, the water consumption of these industries in 2020 is derived as shown in column 2 of Table 6.
It is the English judiciary that is deciding that the betrayal of human relationships through infidelity and consumption of the sex industries – middle and upper-class exploitation of working class personal dignity – is not in "the public interest".
Their results show that the total energy consumption of these four industries could be reduced by about 20%.
Input output tables also show each industry's consumption of the products of other industries, as well as each industry's contribution to the production process.
There were four main criteria presented in level 2 of the hierarchy, which were water pollution, air pollution, energy consumption and resource consumption of paper-making industry and water pollution, air pollution, energy consumption and hazardous waste of printing industry.
Case studies conducted by the authors in the last 10 years demonstrate, that in a number of cases water consumption per production unit of industries from the surface treatment sector, from food processing and from the textile industry could be reduced by 30 90%, auxiliary materials consumption could be reduced by 30 50%, and energy consumption of processes could be reduced by 15 25%.
The quantity of water consumption differs between types of industries.
Furthermore, pollutant emissions and energy consumption of the cement industry under four control scenarios are projected for 2010 2030.
