A rubber compound comprising a conjugated diene polymer and a silica filler wherein the silica filler has a SiO2 content of at least 80% by weight based on the weight of the filler and is obtained from biomass ash comprising rice husk ash, and wherein the conjugated diene polymer is a homopolymer of conjugated dienes or at least one copolymer of conjugated dienes selected from the group consisting of butadiene, isoprene, 1, 3-pentadiene, 2, 3-dimethylbutadiene, 1-phenyl-1, 3-butadiene, 1, 3-hexadiene, and at least one of the conjugated dienes selected from the group consisting of butadiene, isoprene, 1, 3-pentadiene, 2, 3-dimethylbutadiene, 1-phenyl-1, 3-butadiene, and 1, 3-hexadiene, and wherein the polymer is functionalized and comprises at least one functional group. Also provided is a method of making a vulcanizable rubber compound comprising combining the conjugated diene polymer with the silica, and a method of making an article comprising subjecting a curable composition comprising the compound and a curing agent capable of curing the conjugated diene polymer to at least one curing reaction. Further provided are articles obtained from these compounds.
