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

by with No Comment Transportation

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.

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.

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.
