As World Environment Day highlights the importance of working with nature, Rooibos is gaining attention not only for its health benefits, but also for its potential in promoting sustainable practices. Beyond its soothing flavour, Rooibos offers eco-friendly opportunities to repurpose used leaves, aligning with global efforts to reduce waste and support environmental conservation.
Globally, recycling rates have declined for the eighth consecutive year, with only 6.9% of the 106 billion tonnes of materials used annually coming from recycled sources. In South Africa, the situation is equally pressing. Approximately 90% of the country’s waste ends up in landfills, with only 10% being recycled. This linear approach to waste management underscores the urgent need for sustainable practices.
“The single-use model is no longer viable,” says Marthane Swart, secretariat of the SA Rooibos Council (SARC). “We must transition to a circular economy where waste is minimised and resources are reused and recycled. Consumers play a crucial role in this shift by adopting sustainable habits in their daily lives.”
Rooibos, endemic to the Cederberg region in the Western Cape, is not only a beloved beverage, but also a symbol of sustainable agriculture. The Rooibos industry provides income and employment to approximately 8 000 workers in primary production and related activities, such as processing, packaging and retailing.
Swart emphasises the industry’s dedication to sustainable practices.
“The Rooibos industry, deeply intertwined with the rich biodiversity of the Cederberg region, is committed to protecting this natural heritage for future generations. This commitment is reflected in its participation in sustainability initiatives, such as the Union for Ethical Biotrade (UEBT) and Rainforest Alliance certification. As part of these efforts, Rooibos farmers have collectively rehabilitated over 500 hectares of land, actively restoring ecosystems.
“Further bolstering conservation efforts, the Greater Cederberg Biodiversity Corridor (GCBC) has secured 70 406 hectares through formal stewardship agreements, alongside an additional 282 953 hectares under voluntary partnerships between biodiversity organisations and the agricultural sector. These initiatives demonstrate a growing synergy between farming and conservation, ensuring that agricultural growth supports – rather than compromises – biodiversity.
South Africans consume an estimated 3.5 billion cups of Rooibos every year. “That’s a staggering volume – and with every cup comes an opportunity to make a small, but meaningful difference,” says Swart. “By repurposing used Rooibos sachets or loose leaves instead of discarding them, we can collectively reduce waste and support a more sustainable way of living.”
This simple shift in mindset opens the door to creative and eco-friendly reuses. Here are a few easy ways to repurpose leftover Rooibos leaves:
- Natural fertiliser: Rich in nutrients, used Rooibos leaves can be added to compost or directly to soil, enhancing plant growth and soil health.
- Seedling mulch: Sprinkle used Rooibos around delicate seedlings as a light mulch – it helps retain moisture and can gently nourish young plants.
- Exfoliating scrub: The antioxidant properties of Rooibos extend to skincare. Used leaves can be incorporated into homemade exfoliating scrubs, offering a natural alternative to commercial products.
- Deodoriser: Dried Rooibos leaves can absorb odours in refrigerators or shoes, acting as a natural deodoriser.
- Natural dye: The leaves can be used to create natural dyes for fabrics or paper, showcasing the versatility of Rooibos in promoting a zero-waste lifestyle.
- Cleaning agent: The mild acidity of Rooibos makes it suitable for cleaning purposes, such as polishing wooden surfaces.
- Pet care rinse: Rooibos has natural anti-inflammatory and soothing properties, making it a gentle rinse for pets with itchy or sensitive skin.
- Eye compress: Cooled Rooibos sachets or leaves wrapped in gauze can be used as a calming eye compress to reduce puffiness and irritation.
- Moth repellent: Dried Rooibos leaves can be mixed with lavender or cloves and placed in fabric sachets to deter moths in cupboards or drawers.
- Fire starter: When thoroughly dried, Rooibos leaves can be used as a natural fire starter for fireplaces, braais or camping, giving it a second life.
“It’s encouraging to see how aware South African consumers have become of their environmental impact – more than 80% believe they can make a difference by recycling, cutting down on food waste and reducing plastic use.
According to global market research company, Euromonitor International, nearly half of South Africans identify as zero wasters, which shows a real shift in mindset. But, while the willingness is there, which is a vital first step, we urgently need to see more action. Real environmental change depends on turning that awareness into everyday habits.
“As World Environment Day calls attention to the escalating environmental challenges we face, it also serves as a reminder that meaningful change starts with the choices we make each day. From how we consume to how we reuse and recycle, individual actions, when multiplied, can have a significant impact. Embracing sustainable habits – even in simple ways like repurposing everyday items – is key to fostering a culture of responsibility that supports long-term environmental resilience,” she says.
