The primary feedstocks for these Ethanol projects consist of corn and grain (sorghum), yielding an average of around 80 gallons per ton, which is comparable to other feedstocks such as barley, molasses, and wheat.  These Ethanol projects typically involve Greenfield developments and employ the latest technologies for various systems including feedstock preparation, wet milling, mash … Read more

The Biogas to Hydrogen projects closely resemble Anaerobic Digester to RNG projects with additional Hydrogen production equipment. These projects utilize RNG with low Carbon Intensity Scores as the primary feedstock to produce hydrogen.​ The additional technology deployed for these projects includes a Steam Methane Reformer (SMR) utilizing high-pressure and high-temperature steam, a Water-Gas Reactor, Waste … Read more

In areas where distances and proximities are advantageous, the Biogas to District Energy Projects are strategically situated near communities with residential, institutional, and commercial space heating demands. Similar to Biogas to Power and Biogas to Industrial Boiler projects, these initiatives utilize comparable organic feedstocks and technology, yielding similar biogas quantities and heating values from anaerobic … Read more

The Biogas to Industrial Boiler projects utilize similar organic feedstocks as Biogas to Power projects, yielding comparable biogas quantities and heating values from anaerobic digesters or lagoon digesters. The technology for conditioning the biogas are typically determined by the fuel quality and wobbe index requirement set by industrial boiler manufacturers.  These projects span a range … Read more

The Biogas to Power projects utilize a range of organic feedstocks similar to the RNG projects, including dairy manure, food waste, source-separated organics (SSO), Industrial, commercial, and institutional (IC&I) waste, yard waste, agricultural waste, vegetable biomass, and fats, oils, and grease (FOG).  The biogas yields from anaerobic digesters or lagoon digesters for these projects are … Read more

The Wastewater to Renewable Natural Gas projects are commonly situated alongside municipal wastewater treatment plants. These initiatives make use of primary sludge and waste activated sludge (WAS) as feedstock, sourced from various points such as the primary clarifier, secondary clarifiers, or Dissolved Air Flotation (DAF) system.  The Anaerobic Digester technology for these applications are in … Read more

These projects extract landfill gas under a high vacuum, typically ranging from -40” w.c. to -80” w.c. to the gas collection system. The gas is collected from multiple above-ground or below-ground wells through horizontal trenches. New landfills implement a gas collection and flare system that includes dehydration equipment, centrifugal blowers, and enclosed flares. The configuration … Read more

The Lagoon Digester to Renewable Natural Gas projects are specifically tailored for low total solids, typically ranging from 1% to 2%. These projects make use of either an existing lagoon equipped with liner and a cover or a newly constructed lagoon suitable for dairy manure from sand lanes, swine manure, and wastewater with substantial organic … Read more

The Anaerobic Digester to Renewable Natural Gas (RNG) projects make use of a variety of organic feedstocks, including dairy manure, food waste, source-separated organics (SSO), institutional, commercial, and industrial (IC&I) waste, yard waste, agricultural waste, vegetable biomass, and fats, oils, and grease (FOG), among others. The total solids content of the feedstocks we utilize ranges … Read more
