On Friday, April 24, 2026, the Mayor of Kupang, dr. Christian Widodo, visited WITS Group to discuss strategic solutions for sustainable waste management in Kupang City. During the presentation session, WITS Group outlined several major challenges currently faced by the city, including the increasing volume of municipal waste which has exceeded 200 tons per day, limited access to clean water, and the urgent need to develop green industries capable of creating long-term economic value for the region.
The discussion focused on the concept of transforming waste into energy through the processing of RDF (Refuse-Derived Fuel) and SRF (Solid Recovered Fuel) as sustainable alternative energy sources. WITS Group presented how the energy generated from waste processing could potentially support electricity needs, including powering clean water distribution pumps for the people of Kupang.
In addition, WITS Group introduced AI Sorting Technology to improve waste separation efficiency, as well as the Krigsmann Ventra Ultra Jet Turbine Dryer — an advanced drying technology designed to accelerate the SRF drying process with low energy consumption and without direct combustion.
During the visit, WITS Group also introduced the concept of KISS (Kawasan Industri Sampah Sirkular / Circular Waste Industrial Zone), a downstream waste management ecosystem integrating recycling, renewable energy, and green industries into a sustainable circular economy model. This concept is expected not only to address waste management challenges, but also to create new economic opportunities and support industrial growth across Eastern Indonesia.
This visit marks an important first step toward collaboration between WITS Group and the Government of Kupang City in developing a modern, measurable, and sustainable waste management system. Through this approach, waste challenges are not only addressed, but transformed into opportunities toward “A Cleaner, Energy-Independent, and More Valuable Kupang.”
