Method for processing a lactide feed

A method for processing a lactide feed, comprising the steps of

• (a) subjecting a feed comprising L-lactide, meso-lactide, water, lactic acid, and optional further components to a first separation step, the first separation step resulting in the formation of a stream comprising lactic acid and water and one or more crude lactide streams,
• (b) subjecting at least a portion of a crude lactide stream comprising L-lactide and meso-lactide resulting from the first separation step to a first crystallisation step, the first crystallisation step resulting in a purified L-lactide stream and a remnant stream comprising L-lactide and meso-lactide,
• (c) subjecting the remnant stream comprising L-lactide and meso-lactide resulting from the first crystallisation step to a second separation step, the second separation step resulting in at least a second L-lactide stream and a meso-lactide stream,
• (d) subjecting at least a portion of the meso-lactide stream resulting from the second separation step to a second crystallisation step, resulting in the formation of a purified meso-lactide stream and a further remnant stream.
