Developing an efficient waste management system for tea factories in Kenya, A case study of Nyansiongo tea factory

Waste management is a great challenge in tea processing industries in Kenya. The raw materials, energy, labour and water are the major inputs in tea processing that generates solid wastes as dusts and stalks, liquid wastes as fermented liquor and gaseous waste like flue gas and exhaust off tea dryer.

Tea production in Kenya faces a great challenge of high cost of production due to the high cost of inputs. Poor handling and management of wastes can be detrimental to the environment which if managed well will help reduce the cost of tea production in Kenya and will contribute to a better environment. Little has been done on designs on waste management systems in food processing industries in Kenya ignoring vital wastes such as thermal waste.

The broad objective of this study is to develop an efficient waste management system for tea factories in Kenya, a case study of Nyansiongo Tea Factory. The specific objectives are to identify the types of wastes generated during tea production, determine the sources of solid, liquid and gaseous waste in tea production, evaluate existing waste management system and develop a waste management system for the factory.

Data will be collected by measurements, secondary data and interviews with key informants, by the help of semi-structured, observations. The data will be analysed to enable the suitable layout to be made for the factory. The waste management development will minimize the wastes generated and emitted to the environment and also reduce the cost of tea processing in terms of energy.
