Bali’s Renowned Udayana University Houses EX Zero Carbon’s Commercial Pilot in the Region

3 min readApr 22, 2021

Udayana University, a renowned university in Bali, houses the regional commercial pilot of EX Zero Carbon’s portable waste treatment plants. The university, which is located near Bali’s prominent beach areas, has been working to resolve the island’s waste problems for years. The commercial pilot also marks a long, future partnership between the university and the clean technology startup. The machine is currently in the commissioning process.

The patented Zero Carbon system runs on blended, pelletized forms of organic and inorganic waste. EX Zero Carbon named the machines X5 and X50, as the system operates in two different sizes based on the quantity of waste treated. The Zero Carbon process converts these mixed waste streams into clean energy used for household necessities, including electricity, heating, cooling, other household necessities, and biochar. Biochar is an effective carbon sink, and it sequesters carbon dioxide from the atmosphere in the ground soil for generations. The local biodiversity has been seriously harmed in marine environments trying to cope with massive solid and liquid waste emissions.

“Udayana University and the Balinese government have been working for years to resolve the waste treatment problems in the island,” Professor I Nyoman Suprapta Winaya of Udayana University’s Mechanical Engineering Faculty said, “With this machine, Udayana University has become the epicenter of waste resolutions in Bali.”

Other than resolving the island’s waste problems, the Zero Carbon machines will further support the university’s research on waste management for the future. The systems combine mixed waste streams and convert them to generate power sustainably onsite through gasification. It also resolves the problem often occurred by waste management systems. The reactor uses a high temperature of more than 1,000 degrees Celsius, hot enough to destroy all the harmful pollutants. The system uses a patented clinker crushing system that automatically pulverizes clinkers to dust. Combining a low tar process with the innovative clinker crushing system means that the machine can solve ocean waste problems onsite without harmful emissions, a real breakthrough.

EX Zero Carbon’s CTO Michael Hofmeister and his team at Germany’s MFC have been working for the past decade to develop these portable machines. Before release, the innovative and patented systems have undergone more than 30 university tests in Germany’s Zittau Görlitz University of Applied Sciences. The study by the university concludes the viability and process stability of the two machines. EX Zero Carbon has a solid plan to commercialize the machines to the hospitality industry further, and then at the city-level eventually.

“This machine has significantly supported the study and research of Udayana University’s Faculty of Mechanical Engineering,” Professor I Nyoman Winaya said, “The machine also has the potential to build the foundation of sustainable tourism in time to come for Bali. For a self-sufficient community, and a sustainable future.”

EX Zero Carbon selected Bali as the location for the commercial project, as Bali has been negatively affected by a massive waste pandemic eroding the island’s reputation as a pristine vacation destination. The local biodiversity has been seriously harmed in marine environments trying to cope with massive solid and liquid waste emissions.

“We have waste to shape the future of energy generation,” EX Zero Carbon’s CEO Julien Uhlig said, “We have shaped the two machines to optimize the conversion of unutilized trash to be clean energy, with maximum efficiency and minimum cost.”

The EX Zero Carbon team has carefully built the two high technology machines to be easy to use while requiring low maintenance. It only requires around two or three bags of pelletized biofuels a day, and the automated clinker requires water for cleaning. The machine’s functionality can also be managed remotely by the EX Zero Carbon’s laboratory by connecting data and controlling operations. All these features will enable the devices to be used by almost anyone without extensive technical training.

“We aim to have self-sufficient communities who process their waste and use it like electricity or thermal energy,” Uhlig smiled, “Seeing waste as a valuable resource is going to revolutionize the way we live.”
