Abstract

With the establishment of increasing numbers of small breweries the disposal of wet brewery spent grains (WBSG) may pose difficulties in the future particularly for urban breweries and if transport costs make collection uneconomic. The aim of this study is to estimate the transportation cost of spent grains from beverage production. This aim is investigated using a survey addressed to UK breweries. In order to achieve the aim of this study, a model was applied; namely spent grain costing model (SGCM).The SGCM model revealed that the majority of vehicles used to transport WBSG from three different sizes of brewery (small, medium and large) to farms were between 1 to 6 tonne loading capacity and the average distance from these breweries to farms was 5 miles. Data analyses were conducted by three vehicles classes and they were categorized in terms of loading capacity 1 tonne, 3 tonnes and up to 6 tonnes. This analysis was conducted to determine the average cost of transporting WBSG from breweries to farms. The results indicated that the average transport cost per tonne of WBSG for vehicle with the sizes of 1 tonne, 3 tonne and 6 tonnes were £ 10.11, £5.20 and £3.27 respectively.
