Mayor of Kupang Visits WITS Group to Explore Sustainable Waste-to-Energy Solutions

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.”

Wits Group, Together with the Jakarta Environmental Agency (DLH), Visits Biomagg to Develop Maggot-Based Organic Waste Processing

On April 23, 2026, the WITS Group, accompanied by the Jakarta Environmental Agency (DLH), visited the Biomagg facility with the primary objective of learning firsthand about the maggot-based organic waste processing process. This activity is part of WITS Group’s efforts to explore various more effective waste management approaches, particularly for addressing the organic fraction that currently dominates waste composition in many areas.

Biomagg is known as an industry player focused on utilizing Black Soldier Fly (BSF) larvae, or maggots, as a solution for organic waste processing. During this visit, the WITS Group team received a comprehensive explanation of the process, from organic waste receipt, initial sorting, and feeding the maggots. The organic waste used generally comes from food scraps and market waste, which are then processed by the maggots through a natural bioconversion process.

In practice, maggots are capable of decomposing organic waste very quickly, while significantly reducing waste volume. Furthermore, the results of this process also have economic value, as the grown maggots can be used as high-protein animal feed, while the remaining processing residue can be used as organic fertilizer.

During the visit, the WITS Group also directly observed the operational conditions of the Biomagg facility, including the environmental management system, odor control, and process efficiency. Interactive discussions between the two parties also explored the potential for developing this system on a larger scale, as well as opportunities for integration with other waste processing technologies to create a more comprehensive system.

This visit provided WITS Group with important insights into the application of biology-based technology in organic waste management. With a relatively simple yet effective approach, maggot cultivation is a promising alternative solution for reducing the burden on landfills while creating added value from waste.

Through this activity, the WITS Group and Biomagg are opening up opportunities for future collaboration in developing an integrated and sustainable waste processing system. The synergy between technological approaches and nature-based solutions is expected to be a concrete step in addressing the challenges of waste management in Indonesia.

DLH Tangerang City Conducts RDF Technology Trial at WITS Group

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.

WITS Group and Dinas PUPR East Kalimantan Formulate Holistic Waste Strategy: Smart City Source Sorting and Large-Scale MSW Management

On Friday, December 12, 2025, WITS Group held a highly productive and strategic discussion with the Cipta Karya team from the Dinas PUPR (Department of Public Works and Public Housing) of East Kalimantan Province.

The meeting served as a vital platform for exchanging ideas aimed at revolutionizing waste management across cities in East Kalimantan. A highlight of the exchange was the involvement of a dedicated group of young professionals within the Dinas PUPR, whose vision aligns with the need for a comprehensive, end-to-end solution.

The core of the discussion focused on a dual-pronged strategy addressing both the upstream and downstream levels of waste management:

1. Upstream: Smart City–Based Source Sorting

At the upstream level, the strategy emphasizes the implementation of Smart City solutions through the deployment of intelligent waste machines (Smart Bins) at strategic urban locations. These smart units are designed to encourage, monitor, and validate waste sorting directly at the source. By promoting proper segregation within communities, the system aims to significantly reduce mixed waste, improve operational efficiency, and ease the burden on downstream facilities.

2. Downstream: Large-Scale Urban MSW Management

The downstream component focuses on the management of Municipal Solid Waste (MSW) at a large-scale, urban level. Waste that cannot be reduced or fully separated upstream will be handled through integrated, high-capacity processing systems designed to treat large volumes of urban waste efficiently and responsibly. This downstream approach ensures that collected waste is managed in a controlled and environmentally sound manner, completing the waste management cycle from collection to final processing.

This collaboration marks a significant step toward implementing real, scalable solutions, ensuring a cleaner environment for cities across the province.

WITS Group Strategic Review: Organic Waste Challenges and Energy Opportunities at Pasar Induk Kramat Jati

On August 22, 2025, WITS Group revisited Pasar Induk Kramat Jati, the largest and busiest traditional market in Jakarta, to conduct a deeper assessment of its operational and environmental challenges.

The visit yielded a significant and troubling finding: a “mini landfill” operating directly within the market’s boundaries, overwhelmingly composed of organic waste.This discovery provides a stark, ground-level view of a much larger systemic issue. To put the situation in context:

  • Perumda Pasar Jaya manages approximately 154 traditional markets across Jakarta.
  • Collectively, these markets generate around 500 tons of waste every single day.
  • Pasar Induk Kramat Jati is the single largest contributor, producing between 150 to 200 tons of that daily waste.

The visit reinforces a key strategic opportunity that WITS Group is actively exploring. Imagine if this massive, consistent stream of organic waste could be diverted from landfills. Instead of being a problem, it could be processed and converted into a stable energy source, potentially serving as fuel for Indonesia’s power plants (PLTU).

This approach would transform a daily liability into a tangible, sustainable solution, directly supporting Indonesia’s energy and environmental goals. WITS Group is committed to exploring the technologies and partnerships required to turn this vision into a reality.

WITS Group Conducts Strategic Visit to Rorotan RDF Plant to Advance Urban Waste Solutions

On July 29, 2025, WITS Group, alongside our strategic partner PT Wijaya Karya Industri & Konstruksi (WIKA IKON), conducted a strategic site visit to the world’s largest Refuse-Derived Fuel (RDF) Facility located in Rorotan, Jakarta.

This visit was aimed at analyzing the on-ground operations of the state-of-the-art facility, which is designed to process up to 2,500 tons of waste per day. The visit underscores the urgency of the waste management challenge facing the capital. Data indicates that Jakarta produces more than 7,500 tons of waste every single day. The Rorotan RDF facility, which converts waste into a source of energy, represents a significant step forward.

However, the scale of the problem remains immense. Even with the additional capacity from Bantar Gebang processing approximately 2,000 tons per day, this combined output is still far from balancing the daily input. This does not account for the millions of tons already accumulated in existing landfills.

The visit to Rorotan reinforced the conclusion that Jakarta needs real, integrated solutions—not just machines. Success is not measured merely by tons processed, but by the right technology, implemented the right way, and executed sustainably.

WITS Group and PT WIKA Industri & Konstruksi remain committed to pioneering these comprehensive solutions, ensuring that advanced technology delivers a tangible impact on one of the region’s most pressing environmental challenges.
