Company-wide steering instruments and regional action programs

Comprehensive analyses and simulations are the basis for company-wide programs that increase productivity, quality and safety, while simultaneously reducing resource consumption, waste, and maintenance costs. The diversity of our products makes varying demands on our production processes. For example, fundamentally different processes are needed to make tile adhesives, household cleaners, and skin creams, and these processes also differ widely in terms of their water and energy consumption. The experience and activities of our individual plants are therefore channeled into the company-wide efficiency programs. In fact, process-specific ideas and the creativity of employees often make major contributions to the achievement of our objectives.

In addition to optimizing local production processes, the Laundry & Home Care business sector has set itself the goal of reducing the growing complexity between its 31 production sites and its suppliers, distribution centers and customers. A planning and steering system was already introduced for this purpose in 2006, and this has increased the transparency of the worldwide processes. It enables us to identify inefficient processes and effect integral improvements in the interplay of the various partners. For example, we increasingly group production capacities in the geographical vicinity of our markets. Taking a cross-border view of our production network enables us to locate our logistical distribution centers in such a way as to optimize the distance between sites and customers, thus reducing transport mileage to a minimum.

Since 2006, we have systematically carried out analyses of the processes in our eight cosmetics plants as part of our Total Productive Management Plus program. The aim is to identify losses in the various production processes and the supply chain, so that we can continuously increase added value. On the basis of detailed analyses which were carried out at the start of the program, our sites specify actions and quantified targets each year. To achieve these objectives, we rely on the process-specific experience and the ideas and creativity of our employees. To involve all employees as unbureaucratically as possible in the process of continuous improvement, “blue cards” have been placed at clearly visible locations in all cosmetics plants.

Our employees can use these cards to submit suggestions for improving processes. Regarding the production of our Adhesives, Sealants and Surface Treatments, we continued to consolidate our worldwide production network in 2010 and have reduced the number of sites to 149. Key aspects of our production planning are production in the geographical vicinity of our customers, as well as economies of scale and the resulting optimized utilization of resources.

Use of renewable energies

Pilot projects: In Spain, we have installed small-scale solar thermal systems at our sites in Seville and in Montornès (photo). These systems use the heat from solar radiation to provide hot water for the sites.

In the area of climate protection, our primary focus is on the efficient provision and utilization of energy, to prevent climate-damaging emissions in the first place. As a basic principle, we explore all other options for reducing energy consumption first before considering the use of green electricity or carbon offsetting certificates.

Nevertheless, we regularly check whether and where the use of renewable energy sources for electricity generation or the provision of heat is economically worthwhile for us and can make an additional contribution to climate protection. Our Laundry & Home Care business sector has developed a scouting tool to help with this. It takes into account the local availability of different forms of renewable energy, as well as the changing economic conditions and the demand at our sites.

In 2010, as a result of all our worldwide programs, cuts were achieved in energy consumption at 62 percent of our sites, in water consumption at 57 percent, and in waste at 55 percent. We were thus able to further improve our performance on important sustainability indicators in 2010 and have already achieved the 2012 environmental targets we had set for our production sites.

Examples for efficiency programs

Cross-Regional Projects

Efficiency drive:
Excellence in Site Services (EISS) is one of our worldwide efficiency programs. Since 2006, it has helped us to increase the productivity, quality and safety of our sites, while simultaneously reducing resource consumption, waste, and maintenance costs. Comprehensive analyses and simulations often provide a basis for local improvement measures. As a result of the EISS program, we have identified 731 individual measures at our sites worldwide, in the fields of energy, water, waste, building management, safety, health and the environment, and plant logistics.

Wassertrüdingen and Dülken, Germany / Maribor, Slovenia / Sfax, Tunisia / Bogotá, Colombia / Chonburi, Thailand: Numerous optimization measures were carried out in 2010 as part of the Total Productive Management Plus program for our cosmetics sites. These enabled us to reduce the energy consumption by a total of 10 percent, water consumption by 12 percent, and waste by 19 percent.

Europe, Africa, Middle East

European Union: Emissions trading  
Since January 2005, some 12,000 industrial installations in the European Union participate in the world’s largest emissions allowances trading scheme. The objective is to achieve a reduction of 8 percent in carbon dioxide emissions in Europe (base level: 1990) by the year 2012. Henkel’s power plant in Düsseldorf-Holthausen, the company’s largest source of direct carbon dioxide emissions, is subject to the emissions trading scheme. The power station is technically very well equipped. Its efficiency is almost 90 percent, thanks to the especially effective use of cogeneration. As early as 1990, the construction of a gas turbine brought about a reduction of approximately 25 percent in carbon dioxide emissions. With the help of further improvements in energy management and a tripling of the carbon dioxide neutral fuels from production residues, emissions per kilowatt hour of electricity and steam have been reduced by an additional 20 percent since 1990.

Europe: Sale instead of disposal
Marketing of all left-over stocks, including raw materials, packaging, finished products and equipment, via a virtual surplus goods marketplace, where they are sold to interested external parties. Result: significant contribution to avoiding waste and conserving resources by returning surplus materials to the recoverable materials cycle. In addition: considerable savings in disposal and warehousing costs. The money earned covers part of the production and purchase costs of these left-over stocks.
