Successfully producing high quality renewable fuel requires operational consistency, high conversion yields and strong operational controls.

With TWD’s experience partnering with ethanol and biodiesel producers, in addition to the petroleum and chemical industries, we can provide the best solutions: from start to finish, big or small. No matter the feedstock (corn, wheat, fats and oils or cellulose), TWD has helped their clients improve various conversion pathways to liquid fuels:

  • Ethanol

  • Biodiesel

  • Renewable Diesel

Biogas & Renewable Power

TWD carries significant experience in the production of syngas, converting to natural gas, electricity, chemicals or liquid fuels, with a particular focus on emerging technologies to convert low cost, abundant resources such as crop residues, waste wood and organic

by-product and waste streams.

  • Crop Residues:
    Rice hulls, stover, bagasse, potatoes, beets, grasses

  • Wood Waste:
    Sawdust, wood chips, forest waste

  • Organic By-Products and Waste:
    Municipal solid waste (MSW), food waste, grease, manure


  • Milling (wet and dry)

  • Starch conversion

  • Fermentation (batch and continuous)

  • Dehydration

  • Drying

  • Optimization of ethanol use (fuels, beverage, industrial)

  • Optimization of co-products (wet/dried distillers grains with or with out solubles, carbon dioxide)

  • Enzyme hydrolysis

  • Ethanol synthesis

  • Oil extraction
