Our dissolving wood pulp mills

​Our dissolving wood pulp mills

Our production of dissolving wood pulp (DWP) is split between our mills at Saiccor (South Africa), Ngodwana (South Africa) and Cloquet (United States of America). Combined, these three mills can produce more than 1.3 million tons of DWP per annum, accounting for 17% of global demand.

Saiccor Mill
Saiccor Mill is situated 50km south of the port of Durban in Umkomaas, a small town in the province of KwaZulu-Natal. With a capacity of 800,000 tons per annum of sulphite DWP, it is the world’s single largest manufacturing site for DWP.

It also has a long history in DWP production, going back more than 60 years to 1955. Sappi hasn't owned the site for quite that long, but since acquiring the mill in 1989, Saiccor Mill has played a key role in establishing Sappi as the global market leader in DWP.

We achieve this high manufacturing throughput in sustainable style, too – the hardwood woodfibre (Eucalyptus and Acacia) we use in production comes from local, responsibly managed plantations.

Ngodwana Mill

Ngodwana Mill
Ngodwana Mill started producing DWP for global markets in 2013. Its current capacity is 210,000 tons per annum of prehydrolysed kraft DWP.

We produce our DWP at Ngodwana Mill from 100% eucalyptus hardwood, sustainably sourced from suppliers near the mill in the province of Mpumalanga.

A fully integrated kraft mill, in addition to DWP the mill produces paper grade pulp for its own consumption, newsprint and containerboard.

Cloquet Mill
Cloquet Mill started delivering DWP to the market in 2013 following the conversion of its kraft pulp facility – over a century after the original mill opened on the banks of the St Louis River in Minnesota in 1898.

It now has the capability to produce 330,000 tons of kraft DWP per annum, sourced from mixed northern hardwoods – mainly aspen and maple.

The mill employs around 730 people and, alongside DWP production, the mill also specialises in coated free sheet graphic paper and bleached chemical pulp.

Lignosulphonate is a highly soluble lignin derivative and a product of the sulphite pulping process.

Sappi’s patented process, developed with Edinburgh Napier University, reduces the energy required to process woodfibres into nanocellulose thus enhancing our product’s sustainability.
