Recently, pellets (d =6–8mm, L =3.5–40 mm) were prepared from spent coffee grounds (SCGs)/pine sawdust blends according to the French agropellets standard. The performance of these pellets was tested in a domestic pellets combustor. Combustion tests have shown that the boiler performance was very close to the one obtained for wood pellets. Hence, the densification of SCG with pine sawdust may be an interesting valorization route for SCG coffee residues (Limousy,2012).
