13) ENVIRONMENTAL GUIDANCE AND RECOMMENDATIONS
13) ENVIRONMENTAL GUIDANCE AND RECOMMENDATIONS 13) ENVIRONMENTAL GUIDANCE AND RECOMMENDATIONS
1. Disposal of Liquid Effluents
The presence of liquid effluents or non-treated condensation from tank in rivers, lakes or in other water receiving
bodies may adversely affect the aquatic life and the water quality as well.
The condensation withdrawn from the tank, daily, according to the Preventive Maintenance Chapter 9, must be
kept in a container and/or in an appropriate collecting network for further treatment.
Schulz S.A., recommends that the liquid effluent produced inside the receiver of the compressor should be
adequately treated through processes that aim at protecting the environment and the healthy quality of life of the
population, complying with the country current regulation requirements.
Among the treatment methods available, one may choose the physical-chemical, chemical, and biological ones.
The treatment may be carried out by the company itself or by outsourcing.
2. Disposal of Solid Waste (parts in general and product packages)
The generation of solid waste is an important aspect that must be considered by the users when using and
maintaining their piece of equipment. The impacts to the environment may cause meaningful changes in the
quality of the soil, in surface and underground water, and in the population health, due to the inadequate disposal
of the discarded residues (on streets, water springs, landfills, etc).
Schulz S.A., recommends that the waste arising from the product, from its generation, handling, transportation,
and treatment to its final disposal should the handled carefully. Appropriate handling should consider the
following steps: quantification, qualification, classification, reduction at source, pick-ups and selective pick-ups,
recycling, storage, transport, treatment and final destination.
The disposal of solid waste must be carried out according to the regulation requirements of the current legislation
of the country the product has been exported to.
