Our commitment towards sustainable development

The Dal Maso Group is committed to complying with environmental and workplace safety legislation, while seeking ongoing improvements in its environmental performances by continuously monitoring the direct and indirect environmental impact of its work.

The recovery and sanitisation of salt are fundamentally important so we do not put too much stress on purification processes or further clutter up landfill sites. The storage facility has been built and is run to minimise the risk of contamination.

The facility’s specifications

The facility has been built and is run to protect groundwater resources and air quality, while minimising the risk of pollution of the surrounding soil.

Protection of groundwater resources

In order to prevent any potential soil pollution, the facility’s flooring has been made from special corrosion-resistant 35 cm cement, protected by a double wire mesh and waterproofed with a high-density polyethylene HDPE geomembrane (the same used for landfills). The flooring is fitted with a polyethylene sealed drainage system which channels the waste leachate and the washing water into a cistern. This liquid is then extracted and sent to a suitable treatment facility.

Protection of air quality and minimisation of emissions

The same attention is placed on preventing air pollution. To prevent any odours or dust from leaking, the entire facility is completely enclosed and fitted with a forced ventilation system. This system ensures that the air is treated before it is released into the atmosphere, using a wet scrubber with alkaline, acid and oxidative phases.

Minimisation of soil pollution risk

The outside of the entire facility has been made from 35 cm thick cement with a double wire mesh. The water drainage system uses polyethylene sealed manholes. An automatic system controls and manages the first rain and second rain waters; any liquid waste automatically flows into a cistern and is then sent to the treatment facility.

Protection against the risk of hazardous waste

The storage and disposal operations for waste containing asbestos and Eternit carefully follow all applicable legislation in order to prevent their hazardous and carcinogenic fibres from escaping into the environment. Materials containing asbestos are sent to our facility exclusively under approval from the SPISAL-ULSS body which certifies the operational safety plan (POS). The disposal procedure is only used for reclaimed Eternit that is sealed in approved big bags and pallets.
