China yesterday published the nation's first energy-saving
standards for cement manufacturing plants to further increase the
industry's energy efficiency.
Published by the Ministry of Construction, the standards covered
every aspect of cement manufacturing, including plant construction,
manufacturing technology, power systems and equipment use. Some
articles are compulsory.
The standards are a part of the End-Use Energy Efficiency
Program of the Chinese government, run in cooperation with the
United Nations Development Program. The project aims to
dramatically improve the efficiency of China's major energy users:
commercial and residential buildings, and heavy industries, such as
iron, steel, cement and petrochemicals.
"By using the new standards, cement plants can reduce energy use
by about 15 percent," Vice-Chairman of the China Cement Association
Zeng Xuemin said.
The association's chairman Lei Qianzhi said that in the period
of the 11th-Five Year Plan (2006-10), China would cut
energy consumption per unit of gross domestic product (GDP) in the
cement industry by 25 percent, or by 5 percent annually.
Last year, the industry's total energy consumption was
equivalent to 131 million tons of coal. Energy consumption per unit
of GDP in the sector was 12.56 tons of coal equivalent in 2006,
down 10.68 percent from 2005.
The Chinese government has pledged to cut energy consumption per
unit of GDP by 20 percent and reduce pollutant emissions by 10
percent in the five years before 2010.
Cement accounts for nearly half of China's construction
material. By 1985, the country was already the world's largest
cement producer. But many domestic cement companies still use
outdated technology, resulting in significant energy waste and
pollution.
The 10 biggest cement companies in the world currently control
about 80 percent of the industry, while the 10 biggest Chinese
companies only account for 20 to 30 percent of the Chinese market,
Lei said.
To further consolidate the industry, 60 key cement companies
will become industry leaders, according to the National Development
and Reform Commission, the nation's top economic planning body.
