Tea Waste

Tea “waste” is essentially dust, bits and pieces of twigs, damaged fragments of leaf, floor sweepings, stalks, and leftover detritus that doesn’t meet the standards or processes that result in it becoming part of the packaged end product.

Why Tea Waste?

Tea waste has many properties that can be turned into a commercial asset. Waste isn’t necessarily inert. The innovations exploit the chemical and molecular richness of the tea bush and its leaf. Waste retains polythenols, antioxidants, catechins, flavanols, cellulose, amino acid, nonsoluble proteins, caffeine, fiber, sugars, lignin, zinc, and tannic acid that make tea so rich in flavors, textures, and nutrients. The waste is easily processed to extract, mix, and shape these to create value instead of burning or burying it.

Applications of Tea Waste

Caffeine Extraction

Caffeine is widely used in pharmaceuticals as free base and mixtures, such as citrated caffeine, and sodium benzoate. Tea waste are the starting raw materials for its manufacture. Tea waste contains 3-4 percent caffeine. The global caffeine market is predicted to expand at a steady CAGR of around 2.5% by 2022


Tea waste is packed with the compounds that make for a superior fertilizer: nitrogen, potassium and phosphorus. It can be used as a substrate for mushroom growing, vermicomposting — worm activation — compost for foliar (direct leaf) spraying and soil drenching that improve the plant’s access to nutrients and speed up toxin degradation, and specialty fertilizers with high levels of a particular ingredient, such as methane, ash, or potassium.

Energy Source

Tea dust, stalks and all the other little bits of waste can be easily processed and turned into liquids and bricks as biomass fuel, bio-char, and bio-oil. The waste is decomposed using fluidized bed pyrolysis, a thermal decomposition process that occurs in the absence of oxygen. Tea waste pyrolysizes at high temperatures of 500-700°C and through gasification to produce bio-oil and biochar. The char can be converted into briquettes or mixed with biomass.
