Methods and systems for pretreatment of organic waste prior to large-scale production of lactic acid from the organic waste are provided, which employ dried or partially-dried compositions of Bacillus coagulans spores. The methods and systems advantageously provide partial conversion of the organic waste to L-lactic acid already at the pretreatment stage, thereby producing an improved feedstock material for large-scale production of L-lactic acid.
The present invention relates to processes for producing highly pure magnesium L-lactate salt from decomposed organic waste and enriching the enantiomeric purity of recycled lactate salt.
A process for the formation of high-purity magnesium L-lactate crystals from homogenous and heterogenous decomposed organic waste is provided. The process provides magnesium L-lactate crystals with improved enantiomeric purity and overall purity which are particularly suitable for reuse in the production of new polylactic acid.

Systems and methods for processing organic waste, particularly mixed food waste, using a D-lactate oxidase are provided. The D-lactate oxidase eliminates D-lactic acid that is present in the organic waste. The processed organic waste can be used as a substrate in industrial fermentation processes, such as production of optically-pure L-lactic acid. Further provided are systems and methods for producing L-lactic acid from organic waste, in which D-lactic acid that is endogenously found in the organic waste is eliminated using a D-lactate oxidase.
A process for efficient purification of magnesium lactate from fermentation broths derived from non-homogeneous feedstocks that contain soluble and insoluble impurities is provided. The fermentation broth, having high amounts of impurities and containing magnesium lactate in a soluble form, is separated from insoluble impurities, concentrated to particularly high concentrations of the magnesium lactate at elevated temperatures, and subsequently cooled by gradual and controlled cooling such that magnesium lactate crystals of high purity are formed.
