Did you know?

Water and sludge treatment plants are some of the biggest greenhouse gas emitters

Worldwide sludge volumes from sewage plants are increasing by around 5% annually

Up to half of the cost of sewage treatment can be attributed to sludge management and elimination

Sewage sludge management presents a major challenge economically and environmentally.

Orege supports its customers and partners with a global approach aimed at optimizing all stages from conditioning to sludge treatment, helping to make the sludge a product with high added value.

Orege patented solutions enable:

  • Reduction in the volume of sludge produced
  • Optimization of energy and agricultural recovery from sludge (anaerobic / biomethane digestion, production of pellets, spreading, composting).

The sludge conditioned by the SLG can very often become a “recoverable product” and no longer a waste.
