Coated Gravel for Landfills

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 Synstec Solution: Enhanced Gas Capture with Coated Gravel

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

• Increased Surface Area: Synstec 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: Synstec 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:

• 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.

• Landfill Methane Capture and Energy Production: Landfill Methane Outreach Program (LMOP)

How it Works:

1. Gravel Coating: Gravel is coated with our proprietary 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 Synstec 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 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.
