PURAC lactic acid — Corbion

Fermentation-derived L-lactic acid for industrial applications

PURAC is Corbion’s lactic acid portfolio. Its fermentation ingredients are used in industrial formulations; lactic acid is also a chemical building block for producing PLA. Conditions of use: The appropriate industrial grade must be selected. Raw materials, purification and production energy affect its footprint. Related green chemistry principles: 7. Use of renewable feedstocks; 9. Catalysis. The sources are manufacturer or supplier information; they do not represent an independent audit of the product or its life cycle.

Detail of score

The data are calculated with improvements, evidence and connections currently published in EkoPulse.

Model used for this calculation: Impact 2.0 · Reliability 1.3.

Impact: 6 points

Cumulative score

Provisional model: each improvement is assessed by its reach for this profile type, from symbolic to transformative. The same work counts once. Contributions are combined with diminishing returns, and relevant relationships are added. Evidence adds 0 direct Impact points. This does not measure tonnes or net impact.

The highest reach levels require human confirmation; until then they receive a conservative rating. New or edited improvements use a provisional level until their current text is reviewed.

Profile’s own base6
Ecosystem influence+0
Total impact6

The own base combines practices and direct relationships. Direct relationships and ecosystem influence together add at most 4 points. Ecosystem influence can extend up to 3 steps away and depends on relationship trust and nearby profiles’ data. A disputed relationship transmits no influence through the graph, although it can retain direct credit if its category is eligible. Relationships do not generate negative points.

The advisory thresholds are 25 profiles with improvements, 5 with at least 25 points and at least one reaching 95 points. The current figures are 39, 5 and 63, respectively. Reaching these thresholds does not activate comparison: it requires a model decision.

Reliability: C

64 / 100

The model first places the information in a band according to its supporting evidence. It then calculates the score within that band.

Contributions are shown rounded; the total uses the original calculation before final rounding. Ecosystem support is already included and is not added again. Under the current model, the maximum attainable is B+ (84/100).

Evolution of the score

The public record has just begun: for now there is only Insufficient catches to show an evolution. The next captures will be drawing how this score changes over time.

EkoPulse scores are recalculated as the available information changes and the evaluation model evolves. Methodological improvements may result in changes in the score that do not necessarily reflect an equivalent change in profile performance.

Lactic acid via a fermentation route Added by EkoPulseCorbion applies its fermentation technology and lactic acid chemistry to industrial ingredients in the PURAC portfolio. This route makes it possible to introduce bio-based feedstocks into chemical formulations, without automatically considering all production energy renewable.
