The simplest, easiest and most effective solution for the organic fraction treatment.

 Recyclable waste:

  • Organic waste
  • Wood waste
  • Wood chips
  • Compost oversize
  • Bark



  • Organic matter for anaerobic digesters
    Organic ground material,ready to be eaten and attacked by the anaerobic bacteria, during the anaerobic process.
  • Wood fiber
    Lignocelluloseous, fiber-opened material with density from 140 to 200 kg/m³, with chemical and physical parameters similar to peat allows an analogous utilization in agriculture, floriculture and growing media.
  • Compost


 Bioextruder C




Bioextruder C configuration



Treatment capacity

Compost and organic fraction for anaerobic digestion
25 - 40 m³/h, depending on the mixture composition, the structure and the end size of the product required

Wood fiber
20 - 40 m³/h according to the requirements of the product and to the characteristics of the feedstock

The output is a mix with characteristics of high reactivity compared to the raw material, due to:

  • Increased porosity
  • Higher oxygenation capacity.
  • Increase of the surface available for the aerobic bacteria.
  • Structural optimization of the composting material.
  • Reduced moisture content


Bioextrduer Spappolatore2



• Continuous process
• Increase of biogas yield +50%
• No water required
• Low maintenance cost
• Great shorting of the composting time.
• Less surface required for composting.
