Today, orientation towards alternative energy sources has gained great importance. Biomass resources are easily available, plentiful, inexpensive, environmentally friendly and sustainable renewable energy sources. Biomass resources have the potential to be used not only for energy production but also in many different fields. One of the sources of biomass is the tea factory wastes (TFW) released during black tea production. This resource, which has no economic value, can be used in many different fields and forms. In this study, these studies made with tea factory wastes were compiled and gathered under five main headings. These are agriculture and animal husbandry, building materials, environment, energy and chemistry. It is thought that examining the studies in this way will be a guide to fill the existing gaps in the literature and lead to development.
