Our Advances and Production Processes in Environmental Protection

csvwater1.jpgNestlé factories promote rural development, as well as implement new environmental quality standards. Nestlé has made important steps in reducing environmental impacts to improve long-term sustainability.

Production processes at the Kejayan plant are more than sufficient to supply the many different products that meet our commitment to satisfy the needs of valued customers. Not only do we adopt many innovative approaches towards more efficient production and product quality, we also strive to protect the environment we work in, by a variety of methods using the latest technologies.

Combined Electrical and Steam Power

Energy, in the form of steam and electricity, provides the power that fuels our production process. In mid-2008 our production processes were powered by steam, generated by conventional power plants. These plants used two types of fuel oil; Heavy Fuel Oil (HFO) and Light Fuel Oil (LFO), also known as diesel. As part of our long-term plan to further reduce our energy consumption and emissions responsible for the greenhouse effect, we decided to use the combined generator, or cogeneration plant (CPH), so fossil fuels are gradually replaced by natural gas.

In this combined power system, natural gas entering a turbine drives the generator and produces steam; this steam is transferred to a heat recovery device to produce energy. By using energy generated from this gas turbine and steam generator, we can reduce our use of petroleum by 24%.

These combined generators are not only beneficial in terms of energy savings, but also reduce environment impacts. When compared to fuel oil, natural gas produces less carbon dioxide gas, the largest contributor to the greenhouse effect. Coupled with the reduced usage of petroleum, adoption of combined generators has lowered the amount of carbon dioxide produced by as much as 26,000 tons a year. These advances have allowed Nestlé factories throughout Indonesia to reduce their carbon dioxide emissions by 30%. This policy is a manifestation of our commitment to reduce the use of natural resources, using advanced technology to reduce adverse environmental impacts.

Water Management

Many years before protection and conservation of the environment became a public concern, Nestlé had already focused on water management. Over the last decade, our commitment has been to conserve water resources such as wells; paying close attention to any water we use to generate steam, in cooling towers, and for cleaning processes.

Water is heated to produce steam, and then, after it has served its purpose, it is cooled and collected. This condensed water is returned to the steam generator to be recycled to produce more steam, thus conserving water.

Fresh milk arrives from farmers in liquid form. To produce milk powder, water must be separated from the milk solids through the process of evaporation. Once condensed, this water (cow water) is collected in a separate tank and recycled for cleaning tools and used to replace water which evaporates from cooling towers.

Food product production naturally generates quantities of waste water; it is the food industry’s responsibility to ensure this waste water does not damage the environment. We fulfill our commitment to preserving the environment by proper waste management at Waste Water Treatment facilities, or Waste Water Treatment Plants (WWTP), in accordance with national and international standards. Treated waste water also provides benefits to local people, who use it for irrigating their rice fields.

At WWTP, we turn waste water into clean water by the processes of aeration and purification, restoring water’s natural balance. Every day, this facility produces approximately 1,300 cubic meters of clean water. Regular checks, close monitoring and sampling maintains the quality of water produced by facilities. We work closely with local communities and farmers on a canal which stretches for 1.2 kilometers through their rice fields. A total of 26 hectares of fields are irrigated by this channel, in a process with a positive impact on the environment, since farmers no longer have to depend on wells for their irrigation water.

Our initiatives for reducing water usage and saving energy are key elements in our commitment to creating a sustainable environment. We embrace these activities as a global company promoting good nutrition, health and wealth; in addition to environmental benefits, this responsible activity also improves our competitiveness, through increasing efficiency, so our customers can enjoy nutritious and affordable products.
