Venture – CO2 Recovery System

About the Solution:

Venture Engineering & Construction, Inc. is proud to introduce the next evolution in biogas value creation: The Venture CO₂ Recovery System.

If you're operating a landfill gas (LFG) or other biogas to RNG upgrading facility, you're likely venting or flaring your CO₂ tail gas and missing out on a major revenue and tax credit opportunity. Venture Engineering & Construction, Inc. now offers a turnkey CO₂ recovery system that transforms your waste into profit.

The Untapped Revenue Stream in Your RNG Plant

Until now, the biogas upgrading industry has focused on one product: Renewable Natural Gas. The CO₂-rich tail gas, representing 40-50% of your raw biogas volume, has been treated as a waste stream - vented, flared, and considered a cost of doing business.

Recent federal legislation, the One Big Beautiful Bill Act (OBBBA) of 2025, has transformed the economics of carbon capture. Now, you can turn your largest waste stream into two new, high-value products.

At one of Venture’s flagship projects in Humacao, Puerto Rico, they have successfully integrated a state-of-the-art CO₂ recovery system that purifies and liquefies the CO₂ from the RNG tail gas. This proven process creates two distinct revenue streams from the same molecule of biogenic CO₂:

• New Product Sales: We can get you producing a food-grade Liquid Carbon Dioxide (LCO₂), a premium product in high demand by the beverage, food processing, and industrial markets. This stream can range in value from $175/MT to over $500/MT.
• Federal Tax Credits: The new Section 45Q tax credit now provides $85 per metric ton for captured biogenic CO₂ that is sold for commercial use. This credit can be taken as a direct cash payment from the IRS for the first five years, providing a powerful boost to your project's cash flow.
• Proven Performance: Venture doesn’t just engineer it; they build, integrate and operate it. Their first project site is a 25 MTPD (Metric Tons Per Day) system installed at the Humacao LFG to RNG plant. This RNG plant is scheduled to be fully commissioned and achieve COD by Christmas 2025.
• Purity Assurance: Through commissioning testing, the process has proven the ability to produce LCO₂ that meets or exceeds the stringent purity standards for the food and beverage industry.
• Oxidation Catalyst: The Key to Purity The critical step in producing food-grade CO₂ is the complete destruction of volatile organic compounds (VOCs), non-methane hydrocarbons (NMOCs), and any residual methane slip. Venture’s designs include their best-in-class Siloxane/NMOC removal system prior to CO₂ separation to remove 90%+ of unwanted VOCs from the biogas. The CO₂ tail gas stream is then directed to the LCO₂ process that starts with compression followed by a high-temperature oxidation catalyst, as the heart of the process, engineered specifically for the challenges of biogas, specifically landfill gas. It ensures that trace contaminants are catalytically destroyed, guaranteeing a final LCO₂ product that is pure, odorless, and free from hydrocarbons that could create off-flavors in consumer products.
