LANXESS saves 50% of water consumption with retro-washing project at Porto Feliz plant

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) March 26, 2009 -- LANXESS, specialty chemicals company, has saved approximately 50% a year in water consumption through a retro-washing project at its manufacturing unit in Porto Feliz, where iron oxide inorganic pigments are produced and marketed under the brand names Bayferrox® and Xadrez®.
The water re-use system in the plant shows that by efficiently managing scarce resources, it has been possible to achieve outstanding results.

Water consumption has dropped by around 50% on 2004, the year when the retro-washing project was established. The amount of waste has been reduced by around 40%. Moreover, the quality of the product, and therefore competitiveness, have increased.

Data show an annual reduction comparable to the consumption of almost 12,000 households in the city of Porto Feliz.

Retro-washing

In order to improve quality and consequently reduce the consumption of water used in production, the retro-washing process is a set of measures applied in iron oxide inorganic pigment production, from the moment water is collected from the Tietê river to the stage when, after being used in the production process, it is treated once again and returned to the river, following strict parameters. Basically the whole water collection and treatment has been reviewed in detail and made more efficient.

“LANXESS values responsible operations where actions are not only profitable for the company, but also for the community in the surroundings of the units, as well as our partners, clients, suppliers and employees. The continuous development of processes is key to assuring the company’s competitiveness and shows its commitment to the regions where we operate. As current reality has proven, it is a duty to operate sustainably, integrating the economy, the environment, and social competency”, states Robert Madersdorfer, manager at the Porto Feliz plant.

Porto Feliz
The Porto Feliz plant has a production capacity of about 38,000 tons a year of pigments based on iron oxide and exports about 50% of this total to North America, Latin America and Europe. The Brazilian site is one of LANXESS’ largest producers of pigments based on iron oxide and one the Inorganic Pigment business unit’s main plants.
Covering around 572,000 m², the unit employs approximately 300 people. In the region the company is considered to be one of the leading employers, actively participating in the city’s life and contributing to the development of the municipality.
