IWIS states that its production processes do not pollute the air, water or soil, and that the components of all products do not contain toxic substances for humans and for the environment.
We supply our production cycles with the power obtained from renewable sources, with 3 photovoltaic plants, for a total of 440 kWp, and a cogenerator producing additional 800 kW of trigeneration.

Every day, before recirculating it in the environment, we filter 10,000,000 cubic metres of air.
We design energy-efficient production plants.
We optimize the logistic system to speed up deliveries and to reduce vehicle pollution.

We organize our industrial production so as to limit our waste to a minimum: whenever possible, we produce products with recycled materials and application systems and we design product application systems to minimize site waste.
