Indonesian forests pay price for growing global biomass energy demand

Indonesia, Oct. 28: Enormous swathes of pristine forest are being cut down across Indonesia to supply the rapidly rising international demand for biomass material seen as critical to many countries' transitions to cleaner forms of energy.

Nearly all of the biomass from forests destroyed for wood pellet production since 2021 has been shipped to South Korea and Japan, The Associated Press found in an examination of satellite images, company records and Indonesian export data. Both countries have provided millions of dollars to support the development of biomass production and use in Indonesia.

Indonesia's state-run utility also has plans to dramatically increase the amount of biomass it burns to make electricity.

Experts and environmentalists fear the rising international and domestic demand, coupled with weak domestic regulation, will accelerate deforestation at the same time it prolongs the use of highly polluting fossil fuels. Biomass is organic material like plants, wood and waste, and many coal-fired power plants can be easily modified to burn it alongside coal to make energy.

"Biomass production — which is only recently starting to be seen on an industrial scale in Indonesia — is a dire new threat to the country's forests," said Timer Manurung, director of Auriga Nusantara, an environmental and conservation organization in Indonesia.

As countries accelerate their energy transitions, demand for biomass is growing: The use of bioenergy has increased an average of about 3% per year between 2010 and 2022, the International Energy Agency said.

Experts including the IEA say it's important for that demand to happen in a sustainable way, such as using waste and crop residue rather than converting forest land to grow bioenergy crops. Deforestation contributes to erosion, damages biodiverse areas, threatens wildlife and humans who rely on the forest and intensifies disasters from extreme weather.

And many scientists and environmentalists have rejected the use of biomass altogether. They say burning wood-based biomass can emit more carbon than coal and tree-cutting greatly reduces forests' ability to remove carbon from the atmosphere. Critics also say that using biomass to co-fire, instead of transitioning directly to clean energy, simply prolongs the use of coal.

In Indonesia, biomass production is causing deforestation across the archipelago.

Auriga Nusantara reports that more than 9,740 hectares (24,070 acres) of forest have been cleared in areas where biomass production is permitted since 2020. Permits have been issued for over 1.4 million hectares (3,459,475 acres) of energy plantation forests in Indonesia, with over one-third of that land being undisturbed forest. Over half of these concession areas are the habitat of flagship species such as sumatran rhino, elephants, orangutans and tigers, said Manurung.

In the carbon-rich forests of Gorontalo, Sulawesi, the felling, shredding and shipping of old trees to make energy-dense wood pellets has been streamlined. Over 3,000 hectares (7,410 acres) of forest have been razed in a concession owned by Banyan Tumbuh Lestari, from 2021 to 2024, according to satellite analysis shared with AP by international environmental organization Mighty Earth. An additional 2,850 hectares (7,040 acres) were cleared for logging roads. (AP)
