Maguin-Interis units are conceived for the overall integration of energy resources and optimization of their use.

Several levels of energy production can be defined:

• level 1: production of electricity and High Pressure steam (HP)
• level 2: production of electricity and Low Pressure steam (LP), and process vapours
• level 3: process units for Ethanol production, with co-products valuation and possible generation of biogas or process vapour recovered in the units.
