Compost screening for high quality organic fertilizers

Quality separation and maximum yield in less space 

Ecostar has developed specific solutions for the biogas sector, which has been a rapidly growing sector in recent years. Ecostar’s technology is capable of guaranteeing maximum efficiency, flexibility, and compactness in the screening of organic material, green compost, and in the screening of high quality compost, even in the case of material that is wet or mixed with plastic parts.

Compost and the importance of the screening process

When screening compost, the difficulties are mainly due to the presence of plastics and the variability of the material: from high humidity to high volume, up to low density. This makes compost screening a more difficult task, as the material tends to stick and clog traditional screens. With Ecostar dynamic screens, thanks to the patented discs and the anti-clogging system, the material flows over the discs and the separation of the fractions is optimized. This results in an increase in screening quality and a net reduction in maintenance interventions.

The advantages of Ecostar solutions

Ecostar screens work best with both wet and dry material, guaranteeing productivity up to +300% compared to traditional screens.

The best technology for compost screening

DDS (Dynamic Disc Screening) is Ecostar’s patented technology particularly efficient for the processing of compost. The efficiency of DDS enables us the use of smaller electric motors, that is, just 7.5 kW up to 20 t/h, and savings up to 70% on energy consumption compared to traditional screens.
