Should certified and uncertified grades be scored separately?

Yes, certification scope can change availability, lead time, and substitution options.

What scale should I use?

Use your internal FMEA or supplier-risk scale consistently across all biomaterial inputs.

Does high detection score mean good visibility?

In typical FMEA scoring, a higher detection score means weaker detection. Match entries to your team's scoring method.

How can I use the result?

Use it to set safety stock, qualify alternates, negotiate supply agreements, and prioritize supplier development.

Bioplastics & Biomaterials Processing calculator

Biomaterial Supply Risk Calculator

Biomaterial supply risk can be driven by limited fermentation capacity, crop feedstocks, certification scope, compounding capacity, long lead times, regional availability, and single-source additives. Procurement and operations teams use this FMEA-style score to prioritize dual sourcing, safety stock, supplier audits, and formulation alternatives.

What this calculator does

Score supply risk for PLA, PHA, PBAT, PBS, starch blends, cellulose materials, fillers, additives, or certified bio-based compounds using severity, occurrence, and detection ratings.
a materials buyer or production manager needs to rank supply risk for critical biomaterial inputs before committing production or quotes
Returns a comparative supply risk score for one biomaterial input or supplier scenario.

Formula used

Biomaterial supply risk score = supply disruption severity score × supply disruption occurrence score × supply risk detection score
Use the same scoring scale across comparable biomaterial suppliers, grades, and additives.

Inputs explained

Supply disruption severity score: Score impact on production, customer commitments, certification claims, cost, sustainability targets, or product performance.
Supply disruption occurrence score: Score likelihood using supplier history, lead time, single-source status, feedstock volatility, allocation, or logistics risk.
Supply risk detection score: Score how likely forecasts, supplier portals, inventory reviews, audits, or market intelligence detect risk early enough.

How to use the result

Use it for supplier qualification, safety stock planning, quote risk review, alternate resin approval, and production ramp planning.
It is a qualitative ranking tool; critical safety, compliance, or customer risks may require action regardless of numeric score.
