The effect of a composite material additive on the methane production from cheese whey was investigated. Two fractions 2-4 mm and 4-5.6 mm and two modifications by age of material were researched. Whey concentrations of 10 and 15 % were used with 0.6 g composite material addition per g of volatile solids. The additions of composite materials resulted in significant biomethane potential increasing more than two times with 10% whey addition.
