Abstract: A polyhydroxyalkanoate composition, having a an elongation at break (ASTM D648) greater than 3%, an impact resistance (IS0179 1 eA, 23° C., unnotched) greater than 18 KJ/m2 and a flexural modulus of at least 950 MPa, includes at least 25% wt of a polyhydroxyalkanoate component (I); from 5 to 40% wt of one or more thermoplastic polymers as a non-polyhydroxyalkanoate component (II); from 0 to 40% wt of one or more fillers (III); from 0 to 20% wt of one or more plasticizers (IV); and from 0 to 10% wt of one or more additives (V). The polyhydroxyalkanoate composition can be used for the preparation of durable goods that may be labelled as containing more than 20% non-fossil carbon, and for articles prepared therefrom.
