The Environmental Cost of Plastic Packaging: Can the Industry Go Green by 2027?

In the United States alone, the costs of plastic manufacturing, consumption, and disposal are estimated to range from $436 billion to $1.1 trillion per year. Research from Duke University highlights alarming facts about the impact of plastic packaging on human health, greenhouse gas emissions, and waste management.

With growing awareness about plastic’s carbon footprint and its non-biodegradable nature, the packaging industry is undergoing massive changes. Traditional plastic boxes are gradually being replaced by modern, advanced, and recyclable alternatives, thanks to advances in materials science. 

What green options are now dominating the industry? Will they completely replace plastic, or are they still facing some limitations? In this guide, gain insight into modern packaging materials with minimal environmental impact.

Environmental Cost of Plastic Packaging

The environmental cost of plastic is not limited to its non-biodegradable disposal. You have to count in multiple aspects, as per Nicholas Institute for Energy, Environment & Sustainability, Duke University:  

• $410 billion to $930 billion per year for health concerns, including medical expenses.

• $6.4 billion to $15.9 billion for greenhouse gas emissions during fossil fuel extraction.

• $2.9 billion on clearing plastic from landfills by the local government.

• $9.8 billion to $13.3 billion for plastic removal from water, public areas, and roads.

• $3 billion in costs to marine tourism, including degradation of fisheries.

The Rise and Fall of Wood-based Packaging Fibers

Due to the limitations of plastic packaging, there was a shift toward wood-based packaging, with cellulose extracted from trees. This solution addressed several issues, such as biodegradability, renewability, and carbon footprints.

However, a new concern soon emerged in the form of deforestation, the climate crisis, and global warming. This necessitated exploring more advanced packaging materials to overcome the limitations of both plastic and wood-based packaging solutions.

Advancement of Packaging Materials Science

What are the possible choices as an alternative to petroleum-based plastics or wood-based cardstock?

Bio-based Green PE

In renewable energy sources, bio-based PE is serving as an alternative raw material for the packaging industry. Sugarcane is used to produce ethanol, which is then processed to extract ethylene, the main component of polyethylene. It comes with the following benefits:

• Growing sugarcane improves air quality by absorbing carbon dioxide during cultivation. 

• Bio-PE has reduced green gas emissions by 140% than petrochemical polyethylene.

• Bio-based green PE shares similar properties to conventional polyethylene, such as high durability, moisture resistance, and a lightweight structure.

• It is recyclable at conventional recycling facilities, saving cost in the long run.

Hemp-Based Bioplastics

Another advanced packaging material driving the packaging industry's shift toward greener solutions is industrial hemp.  In 2024, the global hemp-based packaging market was valued at around USD 237.3 million, with a production volume of approximately 79 kilotons. It is expected to grow at a compound annual growth rate (CAGR) of 12.4% through 2034. It comes with the following perks:

• Suitable for a wide range of product categories, including food, due to its UV-blocking properties.

• Hemp plants provide a high amount of cellulose, which is otherwise extracted from wood.

• Hemp-based packaging is biodegradable and takes less time to decompose, reducing its contribution to land pollution.

• With fast growth within just a few months, hemp provides access to pulp two or even three times a year.

• Hemp cultivation comes with the lower use of water resources as compared to wood, and grows well with minimal pesticides.

• Hemp fiber wears out slowly, offering longer protection even in moist conditions. 

• With its antibacterial and mold-resistant properties, hemp packaging helps keep food fresh.

Industrial Hemp and Its Potential Uses

Industrial hemp is a specific variety of Cannabis sativa L. that contains less than 0.3% delta-9-THC by dry weight. This industrial hemp has multiple uses, including:

• Fiber production

• Bioethanol and biodiesel fuel generation

• Hemp seed oil and hemp protein powder (considered safe under the U.S. Food and Drug Administration guidelines)

• Extraction of therapeutic compounds such as CBD, CBN, and others.

The Legal Status of Hemp-Based Packaging Material

The new federal legislation in 2025 will potentially ban the majority of hemp-derived edibles under stricter THC limits. This legal uncertainty raises concerns about other industrial uses, including Hemp-based bioplastics. Before shifting completely to green hemp packaging, stakeholders must understand the Industrial Hemp Act of 2023.

This bill provides a separate legal identity to industrial hemp, clearly distinguishing it from marijuana and supporting its cultivation. Its key provisions include:

• Hemp producers must officially designate their crop as industrial hemp.
  

• Certain testing requirements necessary for cannabis extracts are exempted for industrial hemp.
  

• Annual visual inspections are mandatory for every hemp producer.
  

• In the absence of a visual inspection, proper documentation or chemical testing is required.
  

• Individuals with a criminal record related to controlled substances are generally prohibited from cultivating hemp for ten years. However, this restriction does not apply to industrial hemp.
  

• An inconsistent designation of industrial hemp restricts production for five years as a penalty.

Possible Limitations of Hemp-Based Packaging

The benefits of hemp bioplastics are significantly greater than those of plastic packaging. Still, many stakeholders remain hesitant to adopt hemp packaging on a large scale due to several limitations. At present, there are limited extraction and processing facilities that are essential for producing sturdy packaging raw materials.

As compared to traditional packaging material, hemp fibers come with high initial costs. The advanced treatment methods and the underdeveloped supply chain add up to more financial constraints. Most importantly, hemp production yields vary, as does cellulose content, depending on plant, soil, and cultivation methods (inhomogeneity).

What is Inhomogeneity?

Hemp cultivation often results in inconsistent quality, which affects crop yield and fiber strength, and ultimately impacts the performance of final packaging products.  Different environmental factors have a direct influence on hemp chemical composition, causing variation according to different cultivators.

To address this issue, advanced extraction and filtration processes such as DES-based delignification and supercritical CO₂ extraction are helpful. Utilizing these advanced treatments maintains hemp fiber quality and improves the safety and durability of packaging materials.

In Conclusion

The high environmental cost of plastic packaging will soon outweigh its benefits, such as economies of scale, low cost, and easy processing. Issues such as the climate crisis, global warming, and alarming pollution levels are driving the shift toward greener solutions. Advanced packaging materials such as bio-based Green PE and hemp-based bioplastics are now in the spotlight.

In particular, industrial hemp is gaining attention due to its quick cultivation and low environmental impact. Whether this shift will completely transform the packaging industry toward sustainability depends largely on legislative frameworks, possible government incentives, and tax reductions to promote its use. The establishment of more processing and extraction facilities will lead to its mass adoption.

Only a responsible approach from both the production and consumer ends will eradicate plastic packaging completely for a brighter and safer future.
