Waste biological drying

Waste drying before its mechanical treatment not only improves processing quality, but also significantly improves the calorific value and the percentage of final useful product output.

The scientific literature provides a clear substantiation of the impossibility of producing good quality alternative fuel from the municipal waste by only mechanical sorting and shredding due to the low percentage of useful product output and its unacceptably high humidity level.

For a long period of time biological waste recycling technologies were improved and applied for alternative RDF fuel production. It has become clear that waste drying before mechanical treatment not only allows to improve processing quality, but also significantly enhances the calorific capacity and the percentage of the final useful product output.

Dried waste can be used for SRF (solid recovered fuel) and PEF (processed engineered fuel) production.

CHARACTERISTICS

Biodrying is aerobic biological waste treatment for removal of the moisture from its mass. Biodrying is usually one of the stages in production of SRF (solid recovered fuel) and PEF (processed engineered fuel). It allows to dry the waste and enables its cleaner mechanical treatment.

Biodrying is based on the highly efficient and highly automated biological cleaning system, which has 20 years of successful industrial application and continuous research and development efforts.

We decided to present biological drying design solutions as a separate process as well, as earlier it was believed that obtaining SRF fuel of acceptable quality was only possible by mechanical sorting and grinding of waste, and a number of plants were designed and built based on this assumption. It has now become evident from the scientific literature that this assumption was wrong, and that moisture in the waste mass greatly deteriorates the final quality of the produced alternative fuel, its low calorific value being preserved.

We offer a complete set of solutions for modernization of existing SRF fuel plants, adding a biodrying section to them in order to significantly improve the final quality of the alternative fuels.

Proprietary technologies make recycling simple, fast and efficient.
