Possibilities of Applying the Gasification Process in Coffee Grounds Treatment

Abstract

In recent years technological development towards more rational and effective usage of biomass for energy purposes has been observed. A similar tendency has been noted for waste biomass or organic waste from various industries, including agro-food. A good example of such organic waste is coffee grounds, which has been recently generated in increasing quantities and, due to market changes (new commercial networks of coffee-houses), collected separately in significant amounts. The energetic usage of this waste is feasible, yet because of high moisture content (reaching 60%) an appropriate technology has to be applied. One of the possibilities is coffee grounds gasification, which transforms the fuel from solid to gas. The obtained gas can subsequently be combusted in more effective and environmental friendly manner. The article presents an analysis of subjecting used coffee grounds to a gasification process as well as the results of physicochemical tests regarding energetic properties of the material (moisture content, heat of combustion, ash content). Moreover, the article shows the results of applying coffee grounds as an additive to gasification of willow chips, i.a. the influence of the coffee grounds additive on process duration time, temperatures in the reactor as well as energetic effects of the process.
