Seeking the missing sugar feedstock for E20 initiative

Indonesia is preparing to introduce E20, a gasoline blend containing 20 percent fuel ethanol, even as it continues to import sugar to meet domestic food demand. The initiative seeks to replicate the success of the country's biodiesel mandate by reducing reliance on imported gasoline while creating new demand for domestic agricultural commodities.

Under the current roadmap, the government plans to introduce E10 by 2027 before increasing the blend to E20 as early as 2028. However, given Indonesia's limited bioethanol production capacity and the substantial upstream and downstream investments still required, the proposed timeline appears to reflect policy ambition more than industrial readiness.

Much of the government's confidence appears to draw on Indonesia's successful biodiesel experience. However, the comparison overlooks a fundamental difference in feedstock availability. The biodiesel mandate was built on an already mature palm oil industry that consistently generated production surpluses, allowing part of its output to be redirected to energy use without significantly disrupting existing markets.

Bioethanol, by contrast, would rely primarily on sugarcane and its derivatives, where Indonesia starts from a much weaker position. Domestic sugar production remains insufficient to satisfy national demand, forcing the country to rely heavily on imports each year. As a result, scaling up bioethanol production would require not only new ethanol plants and blending infrastructure but also a substantial expansion of sugarcane production.

The difference becomes even clearer when comparing how each feedstock is currently used. Although palm oil is also an important food commodity, Indonesia has historically produced far more than its domestic food market requires. Around 65 percent of the country's palm oil production is exported, while domestic food consumption accounts for only 8.95 million tonnes, or roughly 17.5 percent of total production of 51.3 million tonnes.

By contrast, sugar presents a very different picture. According to Statistics Indonesia (BPS), the country produced only 2.46 million tonnes of sugar in 2024 while importing around 5.3 million tonnes to meet domestic demand. This persistent supply deficit contrasts sharply with the structural surplus enjoyed by the palm oil industry. Consequently, Indonesia has little surplus sugar that can be diverted to fuel ethanol without first expanding agricultural production. Developing a bioethanol industry therefore depends not only on new processing facilities but also on significantly greater sugarcane cultivation.

Recognizing these constraints, the government has paired the E20 roadmap with an ambitious plan to expand both the sugar and bioethanol industries. During the announcement of the E20 program, President Prabowo Subianto said Indonesia would build at least 30 ethanol plants, with the possibility of expanding to as many as 50, to meet future blending requirements.

At the same time, the government has accelerated efforts to achieve sugar self-sufficiency by expanding sugarcane plantations, rejuvenating aging estates, modernizing sugar mills, and encouraging private investment in bioethanol production. These initiatives build on the roadmap established under Presidential Regulation No. 40/2023, which targets self-sufficiency in consumption sugar by 2028, followed by self-sufficiency in industrial sugar and higher bioethanol production by 2030.

However, the government's announcements have focused largely on expanding processing capacity rather than explaining how sufficient feedstock will be secured. While plans for new ethanol plants have been accompanied by broad commitments to increase sugarcane production, officials have yet to present a detailed strategy identifying where additional plantations will be developed, how much production is expected or how feedstock will be allocated between food sugar and fuel ethanol.

Ultimately, expanding ethanol production depends on progress across multiple fronts simultaneously. New processing facilities must be built alongside the rehabilitation and expansion of sugarcane plantations, improvements in agricultural productivity and investments in logistics and fuel distribution infrastructure. Many of these investments take years to deliver meaningful output, raising questions about whether the proposed E10 and E20 timelines are achievable.

As currently designed, the roadmap assumes that agricultural expansion and industrial development will advance in parallel with the fuel mandate, rather than being firmly established before it takes effect.
