Pollution control techniques and technologies for cleaner coal
ABSTRACTThe consumption of coal results in negative environmental impacts. Despite these adverse effects, coal is a significant energy source in the improvement of countries. However, modern technology can be used for cleaner coal. The quality of the coal can be increased with advanced technologies. These advanced technologies build an integral part of sustainable energy and clean coal technology (CCT) programs developed to meet the needs of globalization. This study summarizes developing techniques and technologies in decreasing pollutions from utilizing coal more efficiently. This paper presents information for scientists and engineers to select more cost-effective and environmentally friendly technologies of coal.
This paper presents a study of the technical efficiency of industries in a transitional economy: China. Using data for 28 manufacturing industries across 29 provinces and the Data Envelopment Analysis approach, the technical efficiency of each industry is measured and compared across regions and provinces. The determinants of differential technical efficiency performance are analysed, with a particular focus on the impact of trade orientation and foreign investment. Trade openness is found generally to have a positive effect on technical efficiency.
