Climate Tech Challenge Awards Rp15 Billion for Indonesia Pilots

Three winners, three tracks, one test market

The Climate Impact Innovations Challenge (CIIC) wrapped up its fourth edition with three winners. Each startup came out of a different part of the climate-tech pipeline, and each now has Rp5 billion to prove its technology works in Indonesia. CRecTech won the Energy Transition track, Blueyou took Food & Nature Solutions, and MacroCycle Technologies won Circular Economy. The total pool was Rp15 billion.12 The challenge was presented by East Ventures, Temasek Foundation and Tencent. Organizers say it drew more than 850 applications from about 60 countries.23 Nine finalists received mentoring before the Grand Finale on October 6, which ran as a thematic session of the Indonesia International Sustainability Forum 2026.1

The headline figure is modest by venture standards. What matters more is how the money is structured. The organizers call it "catalytic funding" for piloting, not equity. Eligibility rules required applicants to already have a pilot or minimum viable product built with commercialization in mind.1 CIIC is not trying to pick moonshots out of a lab. It is trying to get technologies that already exist to work under Indonesian conditions, with Indonesian partners.

What the winners are actually building

CRecTech takes biogas from palm oil mill effluent and turns it into bio-methanol. The organizers say the process cuts production costs by 50% and emissions by up to 93%.23 Co-founder and CEO Lim Kang Hui said the award would speed up pilot and commercial deployment with local partners, including state energy company Pertamina. He framed the effort as turning stranded waste resources into fuels for domestic and export markets.1 Indonesian coverage made the same point about Pertamina's involvement, which makes it the clearest named path to commercial scale among the three winners.46

Blueyou combines mangrove restoration on degraded land with blue-food production that uses no feed or chemicals. It claims the model can raise smallholder incomes by up to three times.2 The company's statement focused on restoring mangroves inside working aquaculture ponds. It described the award as a catalyst for scaling integrated mangrove aquaculture across thousands of hectares.13 This is the most socially complex of the three bets. Its success depends on smallholder adoption as much as on biology.

MacroCycle Technologies recycles polyester textiles back into textiles. It says the process uses 80% less energy and 99% less water and emits 80% less CO₂, all at price parity with conventional polyester.214 Co-founder and CEO Stwart Pena Feliz said the prize would launch the company's first project in Asia. He pointed out that more than 80% of textile manufacturing happens in the region, and said the company wants to show that circularity can make economic sense in Indonesia.12

These numbers need a clear caveat. They are self-reported performance claims repeated in the organizers' materials. At least one outlet said explicitly that it had not verified them independently, and that the pilots are what will show whether the benefits hold up locally.1 Indonesian business coverage used similarly careful wording, describing the cost and emissions figures as claimed ("diklaim").46 This seems like the right stance. Price parity in recycled polyester and a 50% cost cut in bio-methanol are big claims, and pilot-scale results often slip once a plant meets real feedstock, logistics and offtake contracts.

Where the coverage diverges: the dollar figure

The main reports agree on the basics: who won, the Rp5 billion per company, the three tracks and the finale date. They differ on what the money is worth in dollars. TNGlobal converted the Rp15 billion to about US$840,000, then rounded down to $800,000 in its headline.3 An Indonesian finance outlet used an exchange rate of about Rp17,880 per dollar, which puts the pool at roughly the same level.6 Dealroom's write-up is internally inconsistent. It gives each grant as US$325.7K, "roughly $280,000," and the total as US$977.1K.12 Those figures don't match each other or the other conversions. The rupiah amounts are the reliable ones. In dollars, each winner gets a little under $300,000, and the total is in the low $800,000s.

The gap is minor, but it shows a common problem when cross-border startup prizes are reported. Converted numbers spread faster than the original ones. Anyone tracking capital flows into Southeast Asian climate tech should anchor to the local-currency amount.

The money beyond the main prize

The most interesting commitment at the finale may not have gone to a track winner. Tencent awarded a US$1 million carbon-credit offtake to Yagasu.2 Yagasu, an Indonesian finalist in the Food & Nature track, says it improves coastal livelihoods by up to 40% across nearly 40,000 hectares of mangroves while generating carbon credits.9 Before the finale, organizers had said finalists could compete for a special award of pre-purchased carbon credits worth up to that amount. AsiaTechDaily noted that this is a forward purchase of credits, not a cash grant, and that it depends on the relevant requirements being met.11

That difference matters. For nature-based projects, a guaranteed buyer for future credits can be worth more than a one-off grant, because it gives the project something to finance against. Tencent joined CIIC this year as a new presenting partner and backed the Food & Nature track.115 Its willingness to commit offtake suggests it sees the challenge partly as a pipeline for high-quality credits, not only as philanthropy. This is an inference, but it fits with Tencent executive Xu Hao's comments about helping nature-based innovations build commercially sustainable models.11

Smaller cheques followed. Sinar Mas Agribusiness & Food gave CRecTech a US$50,000 grant. Vinerock Capital invested US$50,000 in CRecTech, and Mana Impact invested US$50,000 in Blueyou.24 CRecTech ended the night with the most support. Two separate backers came in on top of the main prize, one of them an arm of a major palm-oil group. That match is logical: a palm conglomerate has an obvious interest in technology that turns mill effluent into a sellable fuel.

Reading the applicant pool

The application data give a rough sense of where climate founders are focusing. Circular Economy drew 38.2% of applications, Food & Nature Solutions 34.3% and Energy Transition 27.5%.9 Indonesia sent the most applicants, followed by India, Singapore, the United States and South Korea.9 East Ventures partner Avina Sugiarto said the spread showed opportunities in waste management, resource efficiency, sustainable food, ecosystem restoration and cleaner energy. She also said she was encouraged by more solutions moving past the concept stage toward commercial viability.1

Energy Transition receiving the smallest share is notable for a country whose emissions are dominated by energy. It probably reflects the high capital needs of energy hardware compared with waste and nature-based models, which are easier to pilot at small scale. It also suggests that challenge-style funding fits best in segments where a few hundred thousand dollars can move a project forward.

Why it matters, and what the prize can't do

CIIC has grown steadily. The 2024 and 2025 editions each gave out Rp10 billion in total, with winners including SunGreenH2, Hydrogen Refinery and AC Biode in 2024, and Aslan Renewables, Arukah Capital and SXD AI in 2025.5 Moving to Rp15 billion and adding Tencent signals that the backers are committed and not winding the program down.

The scale of the problem is still very different. Citing the World Bank, AsiaTechDaily notes that Indonesia may need about US$267 billion to US$311 billion in additional climate-mitigation investment between 2022 and 2040, depending on its decarbonisation path.1 No prize closes that gap. What a prize like this can do is lower the risk of the first deployment, which is often the hardest stage to finance. Dealroom made a similar point, describing the grants as small by venture standards but aimed at de-risking early pilots.12

CIIC also isn't the only program of its kind. The Australia–Indonesia KINETIK partnership recently picked nine Indonesian climate businesses for investment-readiness coaching. Through its NEX program, it has also given smaller pilot grants from a pool of IDR 1.6 billion.10 The ecosystem is filling up with early-stage support. The bigger gap is the Series A and project-finance stage that comes after a successful pilot.

On that measure, CRecTech's link to Pertamina and Tencent's offtake for Yagasu are the most important results of the evening. They point to a buyer or an industrial partner, not just a prize. Over the next 12 to 18 months, the question is whether those relationships turn into contracts. If the bio-methanol, the mangrove aquaculture and the recycled polyester can each show their claimed economics in Indonesia, CIIC will have done its job. If not, Rp15 billion will have paid for useful lessons. That outcome isn't worthless, but it is a different result from the one the organizers are promoting.
