On Monday, April 6, 2026, the Environmental Agency (Dinas Lingkungan Hidup or DLH) of Tangerang City visited WITS Group to conduct a trial of Refuse Derived Fuel (RDF) processing technology. The primary focus of this trial was the utilization of the Krigsmann Ventra Ultra Jet Turbine Dryer, a system specifically designed to address one of the key challenges in RDF utilization—high moisture content, which typically remains around 40% and does not yet meet industry standards. The trial was carried out in a structured manner, beginning with the measurement of initial moisture content, followed by the drying process, and concluding with final measurements. The RDF material tested had an initial moisture content of 52.3% and was processed using the Krigsmann Ventra machine with an approximate cycle time of 30 minutes.
The results demonstrated a significant reduction in moisture content to 21.2%, successfully bringing it below the maximum threshold of 25% required by the cement industry. This achievement confirms that the RDF meets the necessary criteria for use as an alternative fuel. Furthermore, the outcome serves as strong evidence that Krigsmann Ventra’s turbine-based drying technology delivers proven performance, particularly in enhancing RDF quality to meet industrial application standards. In addition to the technical trial, the visit also included a brief discussion onintegrated waste management approaches, covering processes from source-level segregation to downstream processing. This exchange provided valuable insights into potential solutions tailored to the needs of Tangerang City. This visit marks an important first step in opening collaboration opportunities between WITS Group and DLH Tangerang City. Supported by measurable and industry-relevant trial results, both parties now have a solid foundation to further explore the implementation of more effective and sustainable waste management solutions.
