How Propane Helps Asphalt Producers Improve EPD Scores

How transitioning to propane improves the asphalt EPD

For asphalt producers, environmental product declarations (EPDs) are not merely a tool for evaluating and communicating one’s environmental footprint, but they are evolving into a component of business strategy, influencing project bids and stakeholder engagement. With this in mind, DCC Propane explored how transitioning from oil to propane in asphalt production can contribute to achieving essential EPD targets.

An EPD offers a transparent view of a product’s environmental footprint, from the extraction of raw materials to its end-of-life management. With these favorable metrics, asphalt mix producers can give themselves a competitive advantage. Asphalt producers with favorable EPDs are better positioned to secure contracts, especially for public infrastructure projects where sustainability is a key consideration. The U.S. Green Building Council’s 2022 report indicated that a significant majority of developers consider EPDs a critical factor in supplier selection. Demonstrating a commitment to reducing emissions and energy use can enhance a company’s reputation and establish it as a leader in environmentally responsible building practices.

Beyond the competitive strategy, producers can see a cost savings when optimizing energy consumption, lowering emissions and minimizing waste. The National Asphalt Pavement Association (NAPA) has reported that adopting energy-efficient technologies, such as cleaner fuels, can reduce energy costs by a notable percentage. That’s where DCC Propane comes in.

Switching From Oil to Propane for Asphalt Production: A Path to Better EPDs

One of the most effective strategies for asphalt producers to cut their environmental impact and enhance their EPDs is by transitioning from oil to propane for drying aggregates and heating asphalt. Here’s why:

1. Lower Greenhouse Gas Emissions: Propane burns more cleanly than oil, resulting in a notable reduction in CO2 emissions per unit of energy produced during the asphalt manufacturing process. By making this switch, asphalt producers can lower their overall GHG emissions, which directly contributes to a more favorable EPD score. According to the U.S. Department of Energy, propane combustion generates less CO2 compared to heating oil per equivalent energy unit.
2. Improved Efficiency: Propane-based systems often exhibit higher efficiency compared to oil-based systems. Propane burners can offer more precise temperature control, leading to reduced energy consumption and waste, further enhancing the environmental metrics captured in an EPD.
3. Fewer Pollutants: Oil-fired systems can release various pollutants, including sulfur oxides (SOx), nitrogen oxides (NOx) and particulate matter. In contrast, propane produces virtually no SOx and significantly lower NOx levels. This results in a cleaner production process and improved air quality, which is reflected positively in an EPD.
4. Cleaner Handling and Storage: Propane is a cleaner-burning fuel, which translates to reduced maintenance requirements and a lower risk of spills or contamination compared to oil. This minimizes both direct and indirect environmental impacts, another factor that can improve an EPD. Furthermore, propane storage often requires less stringent environmental monitoring, potentially leading to cost savings in compliance and safety measures for producers.

Transitioning to Propane

Transitioning to propane is a process that many asphalt producers have already undertaken. To begin the transition:

• Assess Your Current Operations: Conduct a thorough evaluation of your energy usage and emissions.
• Engage with a Propane Supplier: Select a propane supplier with experience in industrial applications, particularly within the asphalt production sector. They can provide guidance and support tailored to your specific needs.
• Develop Your EPD Strategy: Once you have transitioned to propane, collaborate with an environmental consultant or utilize lifecycle cost analysis (LCA) tools to update your EPDs. This will allow you to showcase the improved environmental performance of your asphalt production.

Propane’s Role in a More Sustainable Future

For asphalt producers, prioritizing sustainability and minimizing environmental impact is a fundamental aspect of business operations. EPDs are increasingly becoming an essential requirement for doing business, and producers who proactively take steps to improve their environmental metrics will gain a competitive advantage.

EPDs influence everything from regulatory compliance to competitive advantage. Transitioning from oil to propane offers a pathway to achieving more favorable EPDs by lowering GHG emissions, improving efficiency, reducing pollutants, and offering cleaner handling. By embracing propane, asphalt producers can not only meet growing sustainability demands but also position themselves for long-term success in a green industry.
