The 1973 oil crisis — when OPEC oil embargo dramatically affected petroleum prices and availability globally — substantially affected plastic industry that depended entirely on petroleum feedstock. The crisis indirectly contributed to early bioplastic research interest as industries explored alternatives to petroleum-dependent plastic feedstock. Understanding the historical context provides B2B perspective for plastic industry economic vulnerability and bioplastic alternative development that continues evolving today.

This guide is the working B2B reference on the 1973 oil crisis impact on plastic industry.
Pre-1973 Plastic Industry Context
By 1973, plastic industry was substantial:
Decades of plastic industry development since 1907 Bakelite.
Petroleum-dependent feedstock for essentially all plastics.
Cheap petroleum supporting plastic cost competitiveness.
Industry growth assumed continued cheap petroleum.
Limited bio-based plastic commercial development.
The plastic industry was economically dependent on petroleum.
The 1973 Oil Crisis
In October 1973, OPEC implemented oil embargo:
Petroleum prices quadrupled rapidly.
Petroleum availability restricted.
Industrial impact substantial.
Plastic industry affected severely.
Manufacturing disruption widespread.
The crisis was transformative event for petroleum-dependent industries.
Plastic Industry Response
Plastic industry responded through:
Cost increases passed to customers.
Manufacturing efficiency improvements.
Material recycling initial development.
Various adaptation efforts.
Industry restructuring.
The crisis exposed plastic industry’s economic vulnerability to petroleum supply disruption.
Bioplastic Research Acceleration
The crisis indirectly supported bioplastic research:
Alternative feedstock interest developing.
Bio-based research funding increasing.
PLA research continuing through 1970s-1980s.
PHA research expanding.
Various alternative materials explored.
The 1970s research foundation supported subsequent commercial development through 1990s+.
Modern Bioplastic Industry Foundation
The modern bioplastic industry has roots in 1970s-era diversification interest:
1980s-1990s research building on 1970s foundation.
1997 NatureWorks commercial PLA development.
2000s-2020s bioplastic industry expansion.
Continued development.
What This Historical Context Means for B2B Procurement
Several insights:
Petroleum Supply Vulnerability
Plastic industry remains dependent on petroleum supply chains. Oil price/supply disruptions affect plastic costs.
Bioplastic Economic Diversification
Bio-based plastic provides alternative to petroleum dependence. Modern operations using compostable bioplastic reduce petroleum supply chain exposure.
Long-Term Trajectory
The 1970s → 2025+ trajectory illustrates how industries adapt over decades. Modern compostable industry reflects accumulated multi-decade development.
Future Risk Considerations
Future oil price/supply disruptions could similarly affect plastic industry. Bioplastic supply chains provide some diversification.
For B2B operators evaluating long-term compostable industry trajectory, the 1973 oil crisis history illustrates how external economic shocks can affect plastic industry. Modern compostable industry provides supply chain diversification reducing petroleum dependence — both as environmental benefit and as economic diversification advantage.
The supply chain across compostable food containers, compostable bowls, compostable cups and straws, compostable bags, and compostable cutlery and utensils provides bio-based feedstock alternative to petroleum-dependent conventional plastics. Beyond environmental considerations, the supply chain diversification has economic value protecting against future petroleum supply disruptions.
Compostability Standards Reference
If you are evaluating compostable packaging on a procurement spec, the three claims worth verifying on every SKU are: (1) a current third-party certificate (BPI or TÜV Austria); (2) the underlying standard reference (ASTM D6400 for North America, EN 13432 for the EU); and (3) a clear end-of-life qualifier in marketing copy that complies with the FTC Green Guides. Generic “eco-friendly” or “biodegradable” without certification is the most common compliance gap for U.S. brands.
Frequently Asked Questions
Is industrial composting accepted in my municipality?
Industrial composter access varies by zip code. Use the U.S. Composting Council facility locator and the EPA composting guidance page; if no industrial facility accepts compostable foodware in the customer’s area, the FTC Green Guides require a “compost where facilities exist” qualifier.
What is the difference between BPI-certified and “made with PLA”?
BPI certification is SKU-specific and requires testing of the finished product — including any inks, coatings, and adhesives. “Made with PLA” only describes a single component and is not a substitute. For procurement contracts, lock the certification number, not the material name.
How long does industrial composting actually take?
ASTM D6400 sets the bar at 90% biodegradation in 180 days under controlled industrial conditions (58 °C, controlled moisture). Real-world municipal facilities typically run 60–90 day cycles, faster than the standard worst case. Items still visible after one cycle are typically removed and re-fed, not landfilled.
