Life Dime is an excellent opportunity for surface treatment industries to improve their profitability and make necessary and ambitious improvements in their environmental policies.

Hydrochloric acid and zinc recovery

Cost savings of 60 €/m3 in relation to HCl at 35% by recycling acids from spent baths, thus significantly reducing the consumption of this raw material.

Cost savings of 289 €/t associated with Zn recovery as ZnCl2 will be reused in the fluxing phase of the galvanizing process.

The recovery of marketable products

This process generates marketable by-products in the form of Fe2SO4·7H2O that can be sold to horticulture and viticulture sectors as fertilizers.

According to market research that we have carried out, the income derived from selling this by-product is approx. 40 € per metric ton.

Minimization of liquid waste

The liquid waste to be managed is reduced to a small portion of the initial amount. By the end of the process, it shrinks to around 10% of the input.

Furthermore, Life Dime reduces the consumption of natural resources and CO2 emissions.

LIFE DIME Solution

Life Dime has been conceived as a highly innovative solution for the recovery of hydrochloric acid (HCl) from the effluents of exhausted metal pickling baths. In the case of industries which also use hot galvanizing processes, the exhausted bath contains iron in addition to high levels of zinc (around 25 g/L).

Most of the hydrochloric acid recovered from the spent baths through the Life Dime process is re-used in the same surface treatment process. This significantly reduces the purchase of raw material. In addition, ferrous sulfate is produced in the process, which is a commercially valuable by-product (as a fertilizer in horticulture and winemaking), Zinc chloride is also produced. It, is used in the galvanizing process as one of the basic components of the fluxant (a mixture of ammonium chloride and zinc chloride).

In conclusion, an exhausted pickling bath enters the LIFE DIME process and is transformed into hydrochloric acid suitable for re-use. Ferrous sulfate heptahydrate crystals which can be sold as by-products are also produced in addition to zinc chloride which can be re-used as well.
