Abstract
Tea factories and tea plantations produce a number of by-products such as microfined tea dust, winnowings, floor sweepings, tea seeds and other waste materials. Approximately 2% of the total black tea production goes to waste, amounting to 10 000 t yr-1 under Indian conditions. This paper outlines the approaches to the utilization of by-products from the tea plant. Major uses are the extraction of caffeine, food colours, antioxidants and a plat growth regulator from tea waste. The important uses of saponins and oil derived from tea seeds are also described
