AeroChar Coated Gravel

The Problem: Landfills are a Major Source of Greenhouse Gases

• "Municipal solid waste (MSW) landfills are the third-largest source of human-related methane emissions in the United States, accounting for approximately 14.4 percent of these emissions in 2022." - EPA
• "Landfill gas (LFG) is composed of roughly 50 percent methane and 50 percent carbon dioxide, with methane being a potent greenhouse gas at least 28 times more effective than CO2 at trapping heat in the atmosphere over a 100-year period."
• Existing methane capture systems are inefficient, with "only an average of 34 percent of methane is recovered to produce electricity from landfills."
• EPA: Municipal Solid Waste Landfills: Reducing Methane Emissions

The AeroChar Solution: Enhanced Gas Capture with Coated Gravel

Introducing AeroChar, a revolutionary technology that dramatically improves the capture of landfill gas (LFG). Our innovative coated gravel system offers:

• Increased Surface Area: AeroChar coating dramatically increases the surface area of gravel, providing more points for gas adsorption.
• Enhanced Adsorption: The specialized coating is designed to attract and hold methane and CO2 molecules, maximizing capture efficiency.
• Improved Permeability: The gravel matrix maintains optimal permeability, allowing for efficient gas flow and extraction.
• Durable and Long-Lasting: AeroChar is designed to withstand the harsh landfill environment, ensuring long-term performance.
• Scalable and Cost-Effective: Our system can be easily integrated into existing landfill infrastructure, offering a cost-effective solution for gas capture.

Benefits of AeroChar:

• Significantly Reduced Greenhouse Gas Emissions: Capture more methane and CO2, contributing to a cleaner environment.
• Increased Energy Production: Maximize the recovery of methane for energy generation.
• Improved Compliance: Meet and exceed EPA regulations for landfill gas emissions.
• Enhanced Landfill Management: Optimize gas collection and improve overall landfill operations.
• Potential for CO2 Utilization: Captured CO2 can be used for various industrial applications, including carbon sequestration.

How AeroChar Works:

1. Gravel Coating: Gravel is coated with our proprietary AeroChar material.
2. Placement in Landfill: Coated gravel is strategically placed within the landfill to enhance gas collection.
3. Gas Adsorption: Methane and CO2 molecules are adsorbed onto the AeroChar coating.
4. Gas Extraction: Captured gas is extracted through a collection system.
5. Utilization: Extracted gas is processed for energy generation or other applications.

Our Commitment to Sustainability:

• We are dedicated to providing sustainable solutions for waste management and greenhouse gas reduction.
• Our technology is designed to minimize environmental impact and promote a circular economy.
• We work closely with landfill operators and regulatory agencies to ensure compliance and maximize benefits.

Our approach can fit into existing landfill processes of installing capture piping. Our reasonably priced AreoChar-graphene coated gravel can be a drop-in gravel replacement to installing existing pipes or we believe fully replace the piping w/ a more effective solution capturing over 90% of the gas. We have verified a small-scale experiment and are looking for a landfill partner to develop a pilot projects at scale. Landfills are one of the top producers of these Methane and they have attempted to reduce these outflows with various system of varying success and cost.
