Our Environmental orientation: A fundamental pillar of SANDEN activity

Sewage and industrial water treatment

Three pools for lagoon-based treatment allow natural filtration of sewage from the company site. This is integrated fully with the natural environment of the factory.

Concerning the water from the industrial processes, we have installed an evaporator/concentrator. This system allows an initial distillation treatment of industrial waste water. The ‘clean’ water, separated from the ‘dirty water’, is afterwards reused internally. This solution allows us to reduce our volume of industrial waste water by a factor of 3.

Installation of energy saving solutions

• Though necessary in our industrial processes, the production of compressed air can be very expensive on energy. With the installation of a variable speed air compressor, the rotation speed varies according to demand, therefore reducing blow-off losses. Thus nearly 805MWh were saved each year.
• Installation of a heat recovery unit on an air compressor allows water to be heated to 70°C – 75°C, exploiting the heat generated by our industrial processes, in place of exhausting outside. (waste!). With heat recovery we save nearly 950MWh per year.

Mulching : A  natural method of maintaining the green spaces

In order to encourage biodiversity n our site, situated in the country, we use mulching to maintain our green spaces. This natural technique consists of laying down organic material or minerals surround the base of plants in order to feed and/or protect them.

Through using mulch at the base of our trees, we don’t use biocides (herbicides, fungicides, insecticides) in our green spaces.

For the last 15 years, every waste article is sorted on the SANDEN site in France. Trained in this practice on their arrival at SANDEN, our employees systematically sort their waste, whether in the production, the offices, or relaxation areas.
