ISO 14001 certification of all Degussa’s major production sites, EMAS validation in selected regions |
|
Decentralized implementation by business units |
|
ISO 14001 certification had been achieved for more than 95% of Group-wide production by year-end 2004 |
| Aerosil & Silanes, Rheinfelden, Germany |
|
1. Improve exhaust gas situation to increase availability of plants and reduce emissions |
|
Erect a central thermal exhaust gas scrubbing unit |
|
On cost grounds, it was decided to implement the following measures instead of erecting a central exhaust gas scrubbing unit:
a. Upgrade the existing incineration plant (by 2005)
b. Pressure condensation of exhaust gases (by December 2005)
c. Back-up scrubber for HMDS (by June 2005)
d. Combine exhaust air streams from VE scrubbers (by June 2005) |
| |
|
2. Reduce energy-related carbon dioxide emissions |
|
Extend supply of steam from the cogeneration plant for the northern section of the site |
|
Achieved.The northern and southern sections of the site have been linked via steam and condensate pipelines. Start-up took place on schedule in early 2005. |
| Coatings & Colorants, Herne/Witten, Germany |
|
1. Reduce consumption of natural gas by at least 200,000 m³ p.a. and raise output at the same time |
|
Pre-heat with excess steam, utilize exhaust air, reduce ballast gas in plant, reduce heating requirements by cutting cooling water and brine consumption |
|
The anticipated reduction in consumption of natural gas has been achieved. |
| |
|
2. Reduce wastewater load by 25% in the polyester 1 plant |
|
Introduce a new wastewater treatment process |
|
Test run delayed; expected completion date: 2006 |
| Coatings & Colorants, Marl, Germany |
|
Reduce volume of wastewater by approx. 500 m³ p.a. and reduce wastewater load in synthetic resin production |
|
Switch process from base catalysis to phase transfer catalysis |
|
Changeover delayed; expected to take place by end 2005 |
| C4 -Chemistry, Marl, Germany |
|
Reduce water consumption and amount of wastewater in the raffinate I/II plant by 30% |
|
Reduce wastewater from C4 scrubbers |
|
Target not achieved. Concept was not realized due to technical problems. |
| Exclusive Synthesis & Catalysts, Wolfgang, Germany |
|
Reduce HCl in flue gas by 30% |
|
Connect to thermal afterburner and add flue gas scrubbing step |
|
Target achieved. Connection implemented and scrubber came into operation in 2004; emissions measurements show action was effective. |
| Advanced Fillers & Pigments, Kalscheuren, Germany |
|
Avoid heat and water losses in the gas black plant |
|
Utilize exhaust heat from the plant by decoupling from district heating supply |
|
Achieved. |
| Advanced Fillers & Pigments, Wesseling, Germany |
|
Further reduction (10%) in off-spec products that cannot be recycled |
|
Optimize production planning and process design |
|
Target not achieved. Increased number of start-up procedures due to product changeovers increased off-spec products from 131 metric tons in 2003 to 150 metric tons in 2004. |
| Feed Additives, general |
|
Optimize the use of amino acids in animal feeds |
|
Carry out lifecycle assessments to compare feeds with and without additional amino acids and their ecological profile |
|
Lifecycle analyses of the use of D, L methionine, L-lysine and l-threonine in poultry and pig farming successfully completed. -> See article in Corporate Citizenship Report, page 31 |
| Food Ingredients, Trostberg, Germany |
|
Reduce cooling water in the refrigeration plant by more than 10,000 m³ p.a. |
|
Install a new control valve that is linked to the new computer system |
|
Achieved. |
