1. A process for producing a solid biomass fuel, wherein the process comprises the following steps:
(i) pulverising one or more sources of biomass to provide a biomass powder with an average particle diameter (D50) of from 1000 μm to 6000 μm;
(ii) molding the biomass powder with a compression mold to provide a molded biomass product having a bulk density of from 1.1 kg/L to 1.25 kg/L; wherein the molding is adapted such that the density of the molded biomass product is controlled by using a compression ratio of the compression mold of from 3.8 to 6.5;
(iii) heating the molded biomass product to a temperature of from 160° C. to 420° C. for a time period of from 0.25 to 5 hours so as to provide a solid biomass fuel;
wherein the one or more sources of biomass comprise (i) Calliandra calothyrsusor (ii) a mixture of straw, rice husk, and coconut shell,
wherein the bulk density of the solid biomass fuel as determined according to DIN EN 15103 is from 0.6 kg/l to 0.8 kg/l, and wherein the mechanical durability of the solid biomass fuel as determined according to DIN EN 15210-1 is 95% or more.
