Powering what matters
Transforming waste into renewable resources.
Creating a cleaner, smarter future in Southwest City, Missouri
ReGen harnesses the power of anaerobic digestion to transform byproducts into renewable natural gas, liquid CO₂, and nutrient-rich fertilizer that can be used in agriculture and manufacturing.
Launched in late 2023 and set to be fully operational in 2026, ReGen will significantly reduce waste across Simmons’ operations. But its impact goes far beyond waste reduction:
ReGen supports our long-term focus on efficiency and sustainability, enabling us to unlock shared value and power progress.
Our products
Soil Amendments
Producing concentrated, nutrient-rich solids and liquids targeted for use as soil amendments. These inputs help improve soil health and crop yields, contributing to more effective agricultural practices.
Liquid CO₂
Creating beverage-grade liquid CO₂ that can be used across our operations and beyond. This versatile resource can serve a range of industrial and commercial needs.
Renewable Natural Gas
Producing renewable natural gas and other beneficial products that can be used to generate alternative transportation fuel, energy products, or other advanced biochemicals and bioproducts.
Questions:
-
An anaerobic digester is a sealed system that uses naturally occurring microorganisms to break down organic material, like food byproducts, in the absence of oxygen. As the material breaks down, it produces renewable resources like renewable natural gas (RNG) for energy, liquid CO₂ (LCO₂), and nutrient-rich digestate that can be refined into soil amendment products.
-
We use byproducts from our operations that would otherwise need to be disposed of and considered waste. Throughout the production process, we derive materials that cannot be used to their fullest potential.
-
ReGen will convert low-value materials into renewable resources, including renewable natural gas, liquid CO₂, and soil amendment products that can be used in agriculture and manufacturing.
-
We expect to be fully operational by summer 2026.
