In various embodiments, the present invention provides polymeric compositions that combine polylactic acid (PLA) (or heteropolymers of lactic acid) with additives (organic or inorganic), such as elastomeric additives and/or co-polymer additives. Such polymeric blends may exhibit improved mechanical properties and/or degradation rates compared to PLA homo-polymer (or a lactic acid heteropolymer).
