One aspect of the industry in focus for transformation is the manufacturing process and use of materials sourced from forests. Forest-based products include: natural rubber for shoe soles, paper and packaging, garment tags, retail paper bags, fibre used to make clothes – Man-Made Cellulosic Fibres (MMCF) in particular. MMCF has the third largest share in global fibre production after polyester and cotton. In 2021, MMCFs accounted for 6.4 per cent of the total fibre market, produced primarily from wood transformed into dissolving wood pulp (DWP) before being processed into various types of MMCF, such as viscose, modal, lyocell, or acetate. 

MMCFs are considered a sustainable material due to their circularity and renewable feedstock derived from trees. But to understand MMCFs and how they could be made sustainable, it’s important to understand their source. 

Starting from the Source

Dissolving Wood Pulp (DWP) serves as a crucial raw material in the production of MMCFs and the five largest dissolving wood pulp (DWP) producers are China, the US, South Africa, Canada, and Indonesia. They contribute nearly 60 per cent of global DWP volume. 

Where exactly DWP is sourced from depends on the country. Plantation forests play a significant role in DWP sourcing in South Africa, Indonesia, and Brazil, comprising 7.4, 4.9, and 2.3 per cent respectively of their forests. In Europe, where semi-natural forests are prevalent, DWP primarily originates from these forests. In North America, naturally regenerated forests account for 94.8 per cent in Canada and 91.1 per cent in the US. In China, approximately 20 per cent of forests are plantations, while 61 per cent are naturally regenerating forests.

Risks to Forest Biodiversity

Since the sustainable production of MMCFs begins in the forest, it is crucial for brands to understand the potential risks to forests and take proactive measures to manage and mitigate these risks. 

Forests are home to more than 80 per cent of all terrestrial species of animals, plants, and insects, and are carbon sinks helping to mitigate climate change effects by removing CO2 from the atmosphere and sequestering carbon in trees and soil. They play a crucial role in climate-related risks like extreme weather, wildfire and pest outbreaks by regulating water flows, protecting local communities from extreme weather events, and offering resilient habitats to animal species, but only if they are managed responsibly.

Unsustainable forest management practices, overexploiting forests and timber harvesting at levels that exceed forests’ capacity to sequester carbon cause significant environmental degradation. This is why it is essential to initiate a sustainable forest management strategy aimed at maintaining or increasing forest carbon stocks while producing an annual sustained yield of timber, fibre or energy from the forest.

How Certification Requirements Help

PEFC provides valuable support in mitigating these risks through its rigorous requirements for sustainable forest management. These requirements, encompassed within global and many national standards, ensure that forest operators adhere to robust practices that promote environmental and social responsibility. By understanding and implementing these standards, organisations can effectively address potential risks and contribute to the overall sustainability of forest ecosystems.

The PEFC standard requires forest management to maintain or increase forests and their ecosystem services as well as economic, ecological, cultural, and social forest values. 

It requires degraded forest ecosystems to be rehabilitated as far as economically feasible and adequate genetic, species and structural diversity encouraged, and forest management planning shall aim to respect all socio-economic forest functions. It also obliges forests to maintain or enhance their potential role in erosion control, flood prevention, and other regulating or supporting ecosystem services.

Sustainable Forest Management by Plantation Owners

Asia Pacific Rayon

Asia Pacific Rayon (APR) is emerging as a dynamic player in the realm of viscose rayon production in Asia, sourcing material from Asia Pacific Resources International Limited (APRIL) in Indonesia. What sets them apart? All of APRIL's plantations fall under the canopy of PEFC SFM (sustainable forest management) certification, ensuring a commitment to traceable raw materials. As of December 2022, APRIL is managing a whopping 361,231 hectares of natural forest and wetland areas. Of this area, it restores and protects 150,693 hectares managed under the Restorasi Ekosistem Riau (RER) project, with the remainder being the conservation forest within the operational concession areas of APRIL.

“There is global awareness on the impacts of microplastic pollution, and consumers want sustainable fashion more than ever. Our sustainable, bio-based viscose fibre is one of the solutions to prevent further impacts of non-biodegradable material that leaks into our oceans,” says Basrie Kamba, President Director Asia Pacific Rayon.

“Our fibres are biodegradable, the microfibres that shed into the water system during washing will biodegrade and have no known negative impacts on marine life,” he added.

Sappi

A leading global distributor of both raw materials and a variety of textiles made from wood fibre-base, Sappi takes a strong stance on certified sustainability. Their emphasis on technological innovation is accompanied by a focus on certifications to ensure that their supply chain and operations meet global best practices for the environment.

Duane Roothman, Sappi Forests Vice President explains, “We practise and promote sustainable forestry because it ensures clean air and water, protects biodiversity, and defends against climate change, amongst many other critical benefits. Forest certification validates our forest management practices and those of our suppliers in the well-managed forests and plantations from which we source wood fibre. We strive to continually increase the share of certified wood fibre supplied to our mills.”   

While their own plantations have PEFC forest management certificate, Sappi is also actively advocating for a fully transparent supply chain. To encourage their partner suppliers, the company is developing a supplier sustainability awards program to recognize those who are leading the way.

Guide to Incorporating Sustainability into Sourcing

The PEFC positions itself as a strategic ally for progressive businesses looking for concrete steps to elevate their sustainability efforts into real-world impact. A recent white paper by PEFC on forest-positive MMCF sourcing looks into the potential risks that are impacting forests. The paper explores how sustainable forest management requirements address and mitigate these risks and provides detailed sourcing strategies for fashion retailers.

Suggestions for fashion brands range from ensuring certified materials sourcing as a policy to how they can support their suppliers to succeed in the mission.

“PEFC’s white paper is addressing the urgent need for responsible sourcing practices in the fashion industry," says Julia Kozlik, Textile Program Lead at PEFC International. "By leveraging the knowledge shared in this paper, fashion brands and retailers can make informed decisions, support sustainable forest management, and preserve biodiversity."
