The Case for Sustainable Packaging in Hazardous Material Transport

Why This Category Has Been So Slow to Move

The transport of dangerous goods is governed by a layered international framework. In the United States, the transport of hazardous materials is governed by the Department of Transportation (DOT) through its Pipeline and Hazardous Materials Safety Administration (PHMSA). The Hazardous Materials Regulations (HMR) establishes the requirements for classifying, packaging, labeling, and handling hazardous materials across all modes of domestic transport. Internationally, parallel frameworks govern cross-border shipments, including the European Agreement Concerning the International Carriage of Dangerous Goods by Road (ADR) and the International Maritime Dangerous Goods (IMDG) Code.

Under both U.S. and international standards, packaging used to transport hazardous materials must be independently tested and certified before it can carry a United Nations (UN) approval number authorizing its use with specific goods categories, from flammable liquids and corrosives to toxic substances and oxidizers. PHMSA maintains its own testing and certification requirements for UN-standard packaging manufactured in the United States, and regularly updates the HMR to maintain alignment with evolving international standards.

Introducing recycled content into a UN-approved format isn’t a simple material swap. It requires full re-testing against the same performance standards as virgin material packaging, validation of batch-to-batch consistency, and confidence that the change won’t compromise the properties that earned the certification in the first place. That’s a high barrier, considering the severity of the consequences when packaging fails.

The Demand for Change Is Building

Despite those historical barriers, interest in sustainable DG packaging is growing. A global study conducted by Labelmaster, the International Air Transport Association (IATA), and Hazardous Cargo Bulletin found that nearly half (47%) of DG professionals are very interested in sustainable packaging options over the next five years. Manufacturers are committing to sustainability, in part because it’s becoming a procurement criterion for large industrial customers with their own environmental, social, and governance (ESG) targets to meet.

On the regulatory side, pressure is building from multiple directions. Most U.S. extended producer responsibility (EPR) laws currently exempt hazardous materials packaging, but European legislation can be a sign of what’s coming. The EU's Packaging and Packaging Waste Regulation (PPWR) sets binding recyclability and recycled content requirements for industrial packaging categories, with standards becoming progressively more stringent toward 2030.

Real-world Innovations

Several new formats are demonstrating what’s possible when manufacturers commit to rethinking DG packaging.

FEURER, a German packaging specialist, has developed hazardous goods packaging made from expanded polystyrene (EPS), the lightweight white foam commonly used for protective packaging and often referred to as “Styrofoam,” although Styrofoam is technically a different type of polystyrene foam. Certified by Germany’s Federal Institute for Materials Research and Testing (BAM) and compliant with international dangerous goods regulations for packing groups I, II, and III, the system uses a modular design of base, intermediate rings, and lid that can be adapted to different transport requirements. It eliminates the need for an outer carton entirely, and is made from 100% recyclable EPS, reducing both disposal costs and packaging volume in transit.

PackGen takes a different approach with its line of UN-certified, collapsible composite hazmat containers made from recyclable materials. Its current range replaces conventional drums and Gaylord boxes (heavy-duty industrial containers) with containers that are lighter, stackable, and space-efficient. These large containers are used for a wide variety of applications, ranging from e-waste storage to hazmat transportation.

Lithium battery packaging has seen similar progress. Purpose-built containers engineered with thermal barriers now provide containment for pressure, fire, gases, and projectiles without requiring gel packs, heavy liners, or fillers. They replace conventional cardboard formats that can fuel fires, while making warehousing and transport safer and more cost-effective.

Some manufacturers have also begun replacing single-use shipping cartons with reusable crates made from recycled plastic designed to withstand dozens of cycles. The upfront investment is higher, but the lifecycle economics and emissions profile are significantly better.

ALPLA’s First UN-Approved PCR Canister

ALPLAindustrial has introduced its first canister made from up to 100% post-consumer recycled (PCR) high-density polyethylene (HDPE). These canisters are used for several applications, often in the construction, chemical industry, and agriculture sectors. It’s ALPLA’s first canister of its kind to receive UN approval for the transport of hazardous materials.

The achievement demonstrates that recycled content and UN certification can coexist in a single, commercially available product. The canister meets the same performance standards as its virgin-material equivalent, is designed for industries including chemicals and construction, and is available for immediate production. ALPLA’s customers now have a certified sustainable option without a waiting period.

“This is more than just a packaging solution. It’s a symbol of how industrial sectors can transition to greener practices without compromising on performance or regulatory compliance.”

Manfred Dolotow, ALPLAindustrial Plant Manager

For companies facing tightening EU requirements and customer ESG expectations, the timing makes a difference. ALPLAindustrial Sales Director Oliver Baumgärtel noted that the canister’s immediate availability “supports long-term planning and environmental responsibility.” In a compliance environment where certification timelines are measured in years, that’s a meaningful operational advantage.

The Strategic Case for Moving Now

This is a good moment to rethink DG packaging. Material science has caught up with the safety requirements that once made sustainable formats seem out of reach, and buyers with their own ESG targets are driving demand for packaging partners who can deliver certified, responsible solutions across the supply chain.

European regulatory frameworks have long served as a leading indicator for U.S. policy direction. The EU’s increasingly specific requirements around recycled content and recyclability in industrial packaging give American companies advance visibility into where domestic standards are likely to head, and time to prepare.

The caution that has defined this sector is understandable, and it hasn’t disappeared.

What has changed is that sustainable DG packaging is no longer theoretical. Proven options exist, and the path forward has never been clearer.
