The aim of this research was to find and to evaluate energy crops with respect to their compactibility. Mechanical properties of seven crop species (Sorghum vulgare, Phalaroides arundinacea, Crambe abyssinica, Fectusa pragensia, Camelina sativa, Miscanthus sinensis, Carthamus tinctorius) were evaluated. Briquette densities and the forces required to break the briquettes as well as mechanical parameters influencing the compacting process were determined. The plants were disintegrated in a grinder before the compression. All crops had an unchanged moisture content during the measurement and a uniform output diameter of the briquette of about 65 mm. The moisture contents were as follows: Sorghum vulgare = 10.95%, Phalaroides arundinacea = 11.40%, Crambe abyssinica = 15.97%, Fectusa pragensia = 10.66%, Camelina sativa = 15.37%, Miscanthus sinensis = 9.97%, Carthamus tinctorius = 15.54%. Sorghum vulgare and Miscanthus sinensis were the best crops for briquette production.
