Dissolving pulp: a growing threat to global forest

30 October 2014, Mongabay news - Dissolving pulp is not just a threat to the forests of Indonesia. It is a growing industry across the globe, and it's putting several of the world's endangered forests in jeopardy.

You might not have heard of dissolving pulp, but that doesn't mean you aren't connected to it.

The term "dissolving pulp" refers to wood pulp, bamboo pulp, or cotton pulp with cellulose content over 90 percent. It mostly gets used downstream in what's called viscose fiber, which is made into textiles like Rayon, viscose, modal, or tencel--textiles you might very well be wearing right now.

Industry explosion means bad things for endangered forests

Last year, 6.3 million tons of dissolving pulp were produced worldwide. Most of that, roughly five tons, ended up in clothing, with the rest going into a variety of disparate items, from cigarette filters, toothpaste, and Post-It notes to food (when a food product lists "cellulose" as an ingredient, it generally means dissolving pulp).

But "the lion's share ends up in clothing on sale in high-end boutiques and malls," according to Canopy executive director Nicole Rycroft. The global market for dissolving pulp is expected to double by 2050, Rycroft said, which is why groups like Canopy and the Rainforest Action Network have recently launched campaigns to make the connection between forests being destroyed for dissolving pulp production and the world of high-fashion.

"What we're seeing is this massive ramp-up in capacity," Rycroft said. "Which only means one thing for endangered forests around the world, and endangered species, and it's not a positive thing."

By Canopy's estimates, 100 million trees are cut down every year to make dissolving pulp that is destined for a second life as a piece of clothing, Rycroft said.

Adding insult to injury, dissolving pulp is an extremely inefficient use of trees. On average, the dry weight of dissolving pulp is just 35 percent of the dry weight of the wood fed into the pulping process.

"When you make newsprint, you put ten trees in and you end up with the equivalent of nine trees-worth on the other side," Rycroft said. "But chemical processing with dissolving pulp is so intense, you put ten trees in and you get 3.5 - 4 trees on the other side." The remaining 60 percent of the tree is treated as waste.

A concentrated industry

Because the yield is so low, there is a considerable advantage to companies having their mills producing dissolving pulp in close proximity to the wood source. That's why the biggest dissolving pulp producing countries are those that are "timber rich," in industry parlance.

The top five net exporters of dissolving pulp are South Africa (705,929 tons in 2012), Canada (678,861 tons), the U.S. (405,363 tons), Brazil (390,600 tons), and Sweden (375,987 tons). That's where the majority of the world's mills equipped to produce dissolving pulp are located, as well: There are seven in North America alone, situated close to the conifer forests of the U.S. Pacific Northwest and the Boreal forest in British Columbia and Alberta. There are at least two more in Brazil, in different parts of the Amazon, and one in Sweden.

While data on the exact forests being logged for dissolving pulp is difficult to come by—the companies doing the logging are, for obvious reasons, not forthcoming with these details—it is worth noting that South Africa, the world's chief exporter of dissolving pulp, has lost 17 percent of its forest cover since 2012—almost 860,000 of 5 million hectares—according to data from Global Forest Watch.

Although it is a net importer due to its domestic textile industry, Indonesia dissolving pulp production is on the rise as well. Palm plantations' impact on the forests of Indonesia gets more press, but fiber plantations are actually responsible for more deforestation in the country, with1.9 million hectares of forest loss versus palm plantations' one million hectares according to an article recently published inConservation Letters.

Indonesia currently has the world's highest annual rate deforestation. According to a study by researchers at the University of Maryland, 840,000 hectares of primary forest were lost in 2012 alone, despite high-level commitments by the Indonesian government to combat deforestation.

One of the only mills capable of producing dissolving pulp in Indonesia is owned by Toba Pulp Lestari, which has been singled out by activists at the Rainforest Action Network as "one of the worst actors in pulp and paper." TPL has been accused of human rights violations on its plantations in regards to its labor practices, in addition to contributing to deforestation and loss of habitat for endangered species like the Sumatran orangutan.

Like TPL, which owns the forest concessions being logged to feed its own mill, the dissolving pulp industry as a whole is vertically integrated and concentrated, with just five companies--Aditya Birla Group, Lenzing, Rayonier, Sappi, and Sateri--accounting for 54.5 percent of dissolving pulp production.

Growth driven by China

One of the main drivers of growth in the industry is cotton prices, which dramatically increased in 2010 and 2011 due to widespread cotton crop failures. Since dissolving pulp from wood is a good substitute for cotton, this led to increased demand and higher prices. Plus, with paper being a mature market, companies were already looking to diversify.

But perhaps the biggest factor driving growth in the dissolving pulp sector is China.

Demand for dissolving pulp is driven by demand for viscose fibre, and from 2004 to 2012, global production of viscose fibre grew by 84 percent. Meanwhile, China's share of global production increased from 38 percent to 61 percent. In 2012, China imported nearly 1.7 million tons of dissolving pulp, primarily to make viscose fiber--which makes sense in light of the country's massive textile manufacturing industry, the primary consumer of viscose fiber.

The demand for viscous fiber in China is expected to continue growing at a rate of 10 percent for the foreseeable future, which will of course lead to an increase in demand for dissolving pulp. Efforts are underway to ensure that industry growth doesn't come at the expense of the world's endangered forests, such as commitments by several clothing companies to eliminate fiber produced by their destruction. Here's hoping they're not too late.
