The facility will provide the Municipal Government of the City of Tangerang with an environmentallyfriendly waste management infrastructureAccording to Tangerang Mayor Arief R. Wismansyah, the waste-to-energy plant marks a major breakthrough in the city’s urban waste management.

This Waste-to-Energy facility will consist of two major facilities: a mechanical and biological treatment facility (MBT) located at the Rawa Kucing landfill close to the Soekarno-Hatta International Airport, and an RDF power plant located at an industrial zone location, 14 kilometers away from Rawa Kucing. The facility will be a significant step in building sustainable waste management for the region of Tangerang and serve as a benchmark for modern waste treatment in Indonesia. The waste diverted from landfills will then be reused, recycled, and utilized for energy. It is predicted to save and avoid 12 million tonnes of carbon dioxide emissions across the lifespan of this project – equivalent of more than two years of carbon emissions of the total population of Tangerang, where the project will be located.

Ramboll will be engaged as Oligo’s owners engineer and technical advisor until the financial closure of the project. Its key responsibilities will include procurement and contracting of process equipment – divided into three main packages – the provision of general management and technical advisory services. 

Carsten Schneider, Project Development Director at Ramboll, commented: "We kick-started this engagement with Oligo nearly three years ago in 2019, and we are extremely pleased and honored to come aboard as their trusted partner in the coming phases of this iconic project. This project plays well to our strength as the leading Waste-to-Energy global sustainability consultant, and will no doubt add to our extensive portfolio of Waste-to-Energy projects across the world.” 

"This is also an extremely intriguing project for Ramboll, as we will be mobilizing a team of experts across multiple technical disciplines from our Singapore and Europe offices, in supporting the development of several contracts. We look forward to supporting Oligo in this sustainable endeavor, and in making a real impact towards sustainably managing waste in Indonesia ", added Haoxin Xu, Senior Consultant and Project Manager at Ramboll

The project’s construction phase will start in March 2023 while the commercial operation is expected to commence in June 2025

Ramboll has successfully delivered several Waste-to-Energy facilities around the world. Some of the projects that are under construction include the world’s largest Integrated Waste Management Facility located in Singapore, Dubai WMC, the largest facility in the Middle East, and Australia’s first Waste-to-Energy facility in Kwinana
