Industrial Tea Waste and Energy Potential

Abstract

Türkiye is ranked seventh in the world in tea cultivation and tea cultivation is carried out only in the cities of Rize, Trabzon, Artvin, Giresun and Ordu. The annual production amount of tea is 1.357 million tons and the highest cultivation rate is 67% in Rize City and the lowest is 2% in the Giresun-Ordu region. The tea plant harvested from the field is processed in state or private tea factories. The product obtained as a result of this process is defined as tea, and the remaining parts consisting of fiber, garbage and dust are defined as industrial tea waste (ITW). It is a big problem for both growers and tea operators due to the same harvest time of the tea plant in all cities, the high potential of tea cultivation in the region and the lack of suitable land structure for the disposal of ITW. Removing ITW from the factory environment during the production period and adding to the country's economy as an energy source is important in terms of sustainable energy. In the study prepared with 2023 statistical data, the energy potential that can be obtained by directly burning ITW formed after tea production in factories was examined. As a result, it was found that 1.06e9 MJ of electrical energy and 1.06e9 MJ of thermal energy would be obtained annually if ITW in Türkiye were burned directly in the cogeneration system.
