Vinasse recovery

The recovery of vinasse is one of the many biotechnology solutions offered by INTERIS. Vinasses are effluents with a high hard organic load that necessarily require treatment depending on the raw material fermented.

INTERIS units are equipped with high-performance concentration devices, reducing the volume of vinasse by more than 80% while generating a stable, easily storable residue. This approach results in significant savings on transport costs, particularly for spreading.

INTERIS offers an innovative alternative involving the anaerobic digestion of vinasse. The biogas produced in this way can be recycled by being burnt in a boiler to generate steam or to power a gas engine or turbine, thereby producing electricity.

What’s more, thanks to cutting-edge technology, sugarcane vinasse can be transformed into a solid product that can be used to produce powdered fertilisers, thereby contributing to a more sustainable circular economy.

Incinerating concentrated vinasse or drying methanised vinasse are alternative methods of producing ethanol without generating unwanted liquid effluents.

• 1. Reduced clogging: INTERIS’s cutting-edge technologies reduce equipment fouling, optimising the efficiency of the recovery process.
  2. High concentrations: Thanks to forced circulation and high-performance devices, high concentrations are achieved, making incineration even more efficient.
  3. Optimisation of production time: INTERIS’ advanced methods enable production to be rationalised, reducing stoppages for evaporator cleaning and improving workflow.
  4. Low steam consumption: INTERIS’ technological approach ensures efficient use of steam, contributing to a reduced environmental footprint.
  5. Thermal couplings: Vinasse recovery can be harmoniously integrated with distillation and dehydration, maximising energy synergies and optimising production processes.

  In conclusion, using INTERIS to recover vinasse opens up new prospects for sustainable, energy-efficient and environmentally-friendly production. The advanced biotechnological solutions proposed by INTERIS offer an innovative approach to making the most of these organic effluents while contributing to the transition towards a circular and responsible economy.
