Due to its characteristics Hyst technology has the ability to maintain over time the quality and reproducibility of natural resources, this to preserve biodiversity and to ensure the integrity of ecosystems.

The Hyst process is perfectly sustainable for the environment, because:

• allows you to use profitably waste which is difficult to dispose of,
• requires a reduced amount of energy to operate,
• does not use chemicals,
• does not produce effluents polluting and does not emit greenhouse gases.

In particular , producing biomethane of second generation with agricultural residues, pretreated with Hyst technology, it gives a reduction of CO₂ in the atmosphere.
The inputs ensure a reduced greenhouse gas emissions more than 100%, creating a supply chain to negative emissions (GHG negative).
