PTAR Drives Greener Operations at Martabe Gold Mine with Seven Energy Innovations

PT Agincourt Resources (PTAR) has demonstrated that large-scale mining operations can coexist with environmental sustainability.

The statement was provided by the company following a webinar titled "Clean Energy Goes Viral: Gen-Z in the Energy Transition" which was sponsored in part by PT Agincourt Resources, on Saturday (13/6/2026).

According to the company, PTAR has implemented various advanced technologies to significantly reduce carbon emissions and improve energy efficiency. The company has introduced seven key green initiatives aimed at supporting environmental sustainability.

First, since 2022, PTAR has utilized solar energy through the installation of a 2.0-megawatt-peak (MWp) solar photovoltaic (PV) system. Using an on-grid rooftop system, the solar panels are installed across 42 buildings covering the highland area, lowland area, and employee housing facilities.

Second, PTAR has adopted environmentally friendly heavy equipment in the form of the Komatsu HB365-1 excavator. Through the hybrid technology developed in collaboration between PT United Tractors Tbk and Komatsu, fuel consumption has been reduced by up to 17%, while carbon emissions have declined by 13 kilograms per hour.

Third, in support of Indonesia’s clean energy transition, PTAR has utilized 275,000 Renewable Energy Certificates (RECs) issued by PLN. The amount is equivalent to 275 megawatt-hours (MWh) of electricity generated from renewable energy sources.

Fourth, PTAR has reduced its dependence on fossil fuels by transitioning to B40 fuel, a blend of 40% biodiesel and 60% diesel. The initiative has helped lower greenhouse gas emissions from the mine’s operational vehicles.

Fifth, in its processing operations, PTAR has installed a Slip Energy Recovery (SER) system. The technology captures and regenerates electrical energy that would otherwise be lost, allowing it to be reused. The system has the potential to reduce energy consumption in processing activities by 6.49% per month.

Sixth, the company has significantly improved energy efficiency in its ore crushing operations through the use of Closed-Loop Energy Reclamation technology equipped with Intelligent Torque Control (ITC).

The technology adjusts grinding speed according to the hardness of the ore while simultaneously recovering wasted thermal energy. As a result, electricity consumption has been reduced by 4,931 gigajoules (GJ).

Seventh, PTAR recycles used lubricating oil through Hypobaric Fraction Separator technology. Through a process involving heating, filtration, low-pressure separation, and cooling, the used oil is converted into a substitute fuel for blasting operations.

The program has replaced diesel fuel consumption by utilizing 80% of the waste oil generated. Over the course of a year, PTAR processed 155.25 tons of used oil, equivalent to reducing potential global warming emissions by 441,975.09 tons of CO2 equivalent.

Through a combination of solar energy utilization, hybrid technology, machine intelligence, and used-oil recycling, PTAR says it has demonstrated that gold mining operations can evolve into a cleaner, more efficient, and more responsible industry for the future.
