Contaminants in organic waste

Komptech collaborates with Binder+Co in compost treatment


New limit values for the amounts of contaminants in organic waste represent a major challenge for plant operators. In order to increase the effectiveness of contaminant removal in compost treatment, Komptech and Binder+Co have entered into a technology partnership. The companies are currently working on their first joint project.

Organic waste and fertilizer legislation is requiring further reduction in the amount of contaminants in compost and fermentation residue. These materials are often contaminated with glass, metal, hard plastics and film. Removing these items is a challenge for processing machinery, as the damp organic material makes screening and separation difficult, especially precision separation. Fur-thermore, contaminants are occurring in ever smaller particle sizes.

The combined Komptech and Binder+Co solution brings together different separation steps for compost post-processing, using Komptech machines and a BIVITEC flip flow screen. This technology, developed by Binder+Co, works with flexible screening mats that alternately and very rapidly stretch and compress. The high acceleration of this movement efficiently separates even hard-to-screen materials, and keeps the screen mat openings unblocked.

For the optimum overall solution

Treatment of biogenic waste is one of Komptech’s core competences. The company has extensive process knowledge in this field, and offers suitable machines and systems technology for all treatment steps, from shredding/chipping to rotting to screening and separation. Heinz Leitner, Komptech CEO: “Binder+Co and Komptech are equal partners. Both companies work at a very high quality level, both are very innovative, and both are already collaborating in various R&D projects as technology drivers for the circular econ-omy.” Jörg Rosegger, Binder+Co Board of Directors, adds, “we both have many years of experience in compost treatment, as manifested by satisfied customers around the world.”

The first joint reference system will go into operation in Austria in the coming months. The two companies intend to deepen their technology partnership going forward, and are already working on further innovative solutions.
