Suntory Group has developed a new horticultural soil material made from manufacturing residues, positioning it as a sustainable alternative to peat moss.
The product, called Teamoss, has been created using used green tea leaves generated at Suntory Beverage and Food plants. The company said the material is designed to reduce environmental impact while supporting resource circulation across its supply chain.
Suntory Flowers, which led the development, has applied for a patent covering the process.
Peat moss remains widely used in horticulture due to its water retention and nutrient properties. However, its extraction is increasingly under scrutiny, particularly in Europe, where tightening regulation is driving demand for alternatives.
The new material combines tea residues with wood chips and other inputs. Suntory said internal trials showed plant growth comparable to, and in some cases better than, traditional peat-based growing media.
The company has been recycling all manufacturing residues into animal feed and fertiliser. This latest development expands that approach into higher-value applications.
Commercial production is planned to begin in Japan in 2027. Suntory Flowers is now working on scaling production and expanding trials across a wider range of crops.
The group also signalled potential international expansion, including into Europe, where regulatory pressure on peat use continues to increase.
The move forms part of Suntory’s wider focus on regenerative agriculture and emissions reduction across its supply chain.
Why it matters
Peat alternatives are becoming a priority across agriculture and horticulture as environmental regulation tightens.
For FMCG supply chains, materials like Teamoss could support more sustainable crop production while reducing reliance on carbon-intensive inputs.
Upcycling manufacturing waste into usable agricultural inputs also reflects a broader shift toward circular production models across the food and beverage sector.
