Environmental Requirements in Plastic Parts Manufacturing

Abstract

Plastic—a material that transformed modern life—has now become one of the world’s biggest environmental challenges. From food packaging to automotive parts, its presence is everywhere, but this widespread use comes with serious consequences for our planet. In response, governments and international organizations have developed environmental requirements to regulate the production, design, use, and recycling of plastic parts. These include safe raw material selection, design for recyclability, Extended Producer Responsibility (EPR), emission control, and proper labeling. These are no longer optional—they are the key to survival and competitiveness in the future market (OECD, 2024; UNEP, 2023).

Historical Path to Current Requirements

• 1970s–1980s (Initial Awareness): With the rise of environmental movements, concerns about plastic waste and landfill overuse emerged. The concept of “Reduce, Reuse, Recycle” was born.
• 1990s–2000s (Focus on Hazardous Chemicals): Scientific research revealed health risks of certain plastic additives. This led to the introduction of regulations like RoHS and REACH in Europe.
• 2010s (Single-Use Plastic Crisis & EPR): Shocking images of plastic islands in oceans and the microplastics crisis fueled public pressure. EPR policies were widely adopted, and bans on items like plastic bags and straws began.
• 2020s (Towards a Global Treaty): Realizing that national and regional efforts are not enough, the UN began developing a legally binding global treaty addressing the entire plastic lifecycle—from production to disposal.

Global Perspectives on These Requirements

• Progressive Group (EU, Japan, Canada, etc.): Support strict, binding regulations, focusing on reduced production, elimination of hazardous chemicals, and full EPR enforcement.
• Cautious Group (Oil-producing countries like USA, Russia, Saudi Arabia, Iran): Oppose virgin plastic caps, preferring waste management and recycling innovations. Emphasize national sovereignty in policymaking.
• Developing Countries: Heavily affected by plastic pollution but lacking resources. Advocate for financial aid and tech transfer, emphasizing the responsibility of high-consuming nations.

Sustainable Material Selection and Eco-Design

Modern regulations require producers to consider end-of-life scenarios during the design phase.

Phasing out hazardous substances: Additives like BPA, phthalates (used as plasticizers), and brominated flame retardants (BFRs) are now restricted or banned due to health and environmental concerns.

Eco-Design Principles: Standards like ISO 14006 guide manufacturers to:

• Use recyclable polymers
• Avoid complex multi-layer materials
• Ensure easy disassembly of components for recycling

Extended Producer Responsibility (EPR)

EPR makes producers legally responsible for collecting and recycling their products after use. In many countries, this has become mandatory with fines for non-compliance (OECD, 2024; Nash & Bosso, 2013).

Pollution Control in Manufacturing

Plastic manufacturing releases VOCs, greenhouse gases, and microplastics. Laws like the US Clean Air Act and the EU Industrial Emissions Directive set emission limits, although many experts argue these are insufficient given the rapid growth of the plastics industry (Adler & Wells, 2023).

Labeling and Traceability

To improve sorting and recyclability, many countries require clear labeling of polymer types (e.g., PET, HDPE, PP) on plastic components (RoHS Directive, EU, 2020).

The Future of Global Environmental Requirements

1. Production Caps: A key upcoming debate is limiting virgin plastic production. Many argue that waste management alone is ineffective without addressing upstream production.
2. True Circular Economy: A shift from “recycling” toward systems emphasizing repair and reuse, with multi-lifecycle design principles.
3. Digital Product Passport: Each plastic product will carry a digital identity including composition, recycled content, and recyclability info.
4. Alternative Material Innovation: Heavy investment is being directed toward truly biodegradable and compostable materials for specific applications.

Policy Recommendations for Iran

1. Adopt national EPR legislation: Focus on packaging, beverages, and electronics. Producers should financially contribute to collection and recycling systems.
2. Develop modern recycling infrastructure: Invest in sorting and recycling plants. Support and formalize the informal waste sector.
3. Establish clear labeling standards: A unified labeling system to identify plastic types for consumers and recyclers.
4. Offer tax incentives for green industries: Support companies using recycled materials, designing recyclable products, or reducing plastic use.
5. Phase out unnecessary single-use plastics: Begin with plastic bags, foam containers, and straws—support local sustainable alternatives.

Conclusion

Environmental regulations—from design to end-of-life—are being implemented globally to address the plastic crisis. Complying with these rules is not only essential for environmental preservation but will soon become mandatory for exporting and manufacturing plastic products.
