2005-2009 Work Summary of Emission Reduction
-- - Providing Low Carbon Economy New Type of Operation materials for interview

In recent years, Group Company has emphasized assessment and guidance of development of energy conservation and emission reduction, broken down the work objective and mission of emission reduce by levels to subordinate enterprises, monitored implementation situation at all levels, established responsibility system for the company''s management to workers at the production line as well as from Group Company to positions at basic level, and formed the work system of "Responsibility implemented by levels and pressure passed by levels". In 2009, XD Group invested RMB 8.52 million Yuan in environmental protection reconstruction in technological upgrading projects to try to reduce the discharge of COD and SO2. Discharge of COD in 2009 was reduced to 442.9 tons, discharge of sulfur dioxide was reduced to 53.6 tons, respectively year-on-year reduced by 9.14% and 19.65% compared with 2005, consequently totally completed assessment objective within 2007-2009 tenure of 8% emission reduction transmitted by the State-owned Assets Supervision and Administration Commission.


We will also manage pollution emission reduction as an important job for following a scientific approach of development and promoting good and fast economic development, stress to take technological upgrading projects as platform, strictly implement energy conservation and emission reduction, and seek for new breakthrough in key working procedures of emission reduction. For example, we will reduce the discharge of COD and SO2 fundamentally by means of implementing on-line monitoring, wastewater treatment, reclaimed water reuse transformation, kiln waste heat reuse, waste gas burning heat energy reuse projects, etc.


In recent years, all subsidiaries of Group Company have implemented large-scale technological transformation, all projects were strictly examined and approved concerning environmental protection before they are transformed in accordance with principle of "replacing old with new". As deepening of technological transformation, improvement of environmental protection management, progress of emission reduction technology as well as adjustment and enhancement of technology, Group Company''s comprehensive discharge of atmospheric pollutant has been significantly reduced. Although the production scale has been expanded in successive years and discharge of wastewater has also increased over the same period of the previous year, yet comprehensive energy consumption for unit output value has been greatly reduced, main pollutant discharge has been effectively controlled, thus realizing standard discharge and ensuring the sustainable production development of Group Company!
 
In recent years, XD Group''s main work in environmental protection as flowing:
Establish a leader group of Group Company in charge of emission reduction. Lead, direct and coordinate each unit of Group Company the work of energy conservation and emission reduction.
