飲茶文化是台灣生活中的一部分，每年瓶裝茶飲產生27萬噸的茶渣，過去茶渣都被用來作為堆肥，但茶渣中的茶多酚、多孔性結構以及茶香味都有很好的應用價值。唯一缺點是茶渣的水分含量高、易腐敗，因此博堯生技利用微生物發酵的方式延長茶渣的保存及穩定茶渣的品質，再製為貓咪家庭需要的“BIOYO益生菌茶葉貓砂”，以天然再生原料製作貓砂，降低環境負擔，延長茶葉使用週期，產品中更添加氨氣降解益生菌，增添貓砂除臭特性，在優化產品的同時更涵蓋了守護地球的理念。
The culture of drinking tea has become a part of Taiwanese life. Every year in Taiwan, bottled tea produces 270,000 tons of tea residue. In the past, these residues were used as compost. However, the tannins, porous structure, and aroma in tea residue have significant application value. The only downside is that the moisture content in tea residue is very high, which makes it prone to decay. Therefore, BIOYO Biotech has extended the preservation of tea residue and stabilized its quality through microbial fermentation, and then produced “BIOYO Probiotic Tea Leaf Cat Litter” as needed by households with cats. This cat litter is made from natural regenerated materials, reducing the environmental impact and prolonging the use cycle of tea leaves. Moreover, the product has added ammonia-degrading probiotics to enhance the odor-removal feature of the cat litter, optimizing the product while conserving our Earth.
