Installation of the SCS Multilevel Thermal Sludge Drying System by i+M Zizmann

Project : Miquel y Costas (Barcelona)

The paper company Miquel y Costas, located in Barcelona, has trusted the innovative technology developed by i+M Zizmann, a European leader in thermal drying systems, to implement the first plant in Spain using the SCS Multilevel Dryer system.

This project was managed by B2S Renewable Energies, the exclusive representative of i+M Zizmann in Spain, who coordinated the installation and commissioning, ensuring the success of this cutting-edge technological solution.

TECHNOLOGICAL INNOVATION by i+M Zizmann

The SCS Multilevel Dryer System, designed and manufactured by i+M Zizmann, combines decades of experience in thermal engineering with a focus on sustainability and operational efficiency. Its advanced design optimizes sludge treatment, providing tangible benefits in terms of performance and environmental impact.

KEY IMPROVEMENTS OF THE INSTALLATION

Reduction in Sludge Volume

• Capacity: 400 t/year of dewatered sludge (50% DS).
• Final dryness: 90% DS.
• Volume reduced to 222 t/year.

Sludge Revalorization

• Reusable product with high calorific value (LHV).
• Alternative fuel to fossil sources with neutral CO₂ emissions.

Energy Savings

• Use of residual thermal energy to heat water to 85 ºC.
• Elimination of energy costs associated with the process.

Uniformity and High Drying Efficiency

• Evaporation: 178 t of water/year.
• Thermal consumption: 258,000 kWh/year.
• Compact footprint of 12 m².

TECHNICAL DETAILS OF THE EQUIPMENT

• System with 4 drying levels and concrete platforms.
• Integration of underfloor heating collectors for hot water circulation.
• Continuous sludge transfer and turning by rakes with chains:
o Maximization of contact with hot air.
o Avoidance of anaerobic zones.
o Production of dry, homogeneous granules automatically
extracted to a container.

ADDITIONAL ADVANTATGES

Modular and Scalable Design

• Containerized configuration.
• Possibility to expand capacity as needed in the future.

Contribution to Sustainability

• Significant reduction in greenhouse gas emissions.
• Minimization of the carbon footprint.

PROJECT IMPACT

This project reflects the technological excellence of i+M Zizmann as an inventor and leader in thermal, hybrid, and solar drying solutions, and highlights the fundamental role of B2S Renewable Energies as a representative in Spain to coordinate its implementation.
Thanks to this collaboration, Miquel y Costas has transformed its waste management, setting a benchmark for circular economy and sustainability in the paper industry.

With this installation, the combination of innovation, operational efficiency and environmental commitment positions the company as a reference model for the industry.
