An at least two layer rotomolded article can include a layer A and a layer B. Layer A can include an aliphatic polyester selected from polyhydroxyalkanoate, poly(lactic acid), polycaprolactone, copolyesters and polyesteramides. Layer A can include a polyolefin. Layer A can include a co- or ter-polymer that includes ethylene or styrene monomer, an unsaturated anhydride-containing monomer, epoxide-containing monomer, or carboxylic acid-containing monomer, and a (meth)acrylic ester monomer. Layer B can include a polyolefin and a polyester. Layer B can include a co- or ter-polymer that includes an ethylene or a styrene monomer, an unsaturated anhydride-containing monomer, epoxide-containing monomer, or carboxylic acid-containing monomer, and a (meth)acrylic ester monomer.
