icona industry 4.0 Dal Maso Group

Development and innovation:
our 4.0 salt-treatment system

Thanks to recent investments, the system we use to treat salt has been totally automated for management and processing. Our new digital systems and the installation of latest-generation components has enabled us to improve both productivity and the effectiveness of the end product itself, optimising consumption and reducing environmental impact.

The patented salt recovery system

Strengthened by twenty years of experience built up over the years, the Dal Maso Group has developed a patented system for the recovery of salt from the tanning and food sectors.


This process involves a kind of full cycle to recover the salt. Once it has been treated, it is ready to be placed on the market as a de-icer for road maintenance during winter. The sanitisation treatment is carried out through a thermal process, using a high-temperature furnace that allows us to recover all of the treated material, completely removing the dangerous bacterial load.

The subsequent phases to mechanically separate the organic and inorganic parts are carried out through a complex sieving system. This produces an end product that is classified as a raw material and is suitable for sale and use for anti-icing roads. The waste from this process (wood, paper, dung, hair and other material) is reused by companies that produce ingredients for natural organic fertilisers to be used in farming.


The certification of our quality, environmental and safety management systems ensures that our services are provided in line with certain specifications to guarantee consistent quality with the utmost respect for the environment and for people’s safety.

The company has specifically been certified for the collection, transport, storage and mixing of hazardous and non-hazardous special waste intended for disposal and/or recovery. Brokerage of hazardous and non-hazardous special waste, without holding. Recovery of salt from the tanning and agri-food sectors, through a thermal sanitisation process and mechanical separation phases for the organic and inorganic parts, producing a raw material used for anti-icing roads.
