Biodegradable copolyesters are processed primarily through extrusion and injection moulding. This paper presents preliminary investigations into the grinding and rotational moulding characteristics of commercially available biodegradable copolyester. Cryogenic grinding and subsequent rotational moulding experiments on the copolyester resin resulted in complete mouldings of uniform wall thickness being produced. It was observed that peak internal mould air temperatures of approximately 150 degC are required in order to produce acceptable mouldings.
