sunliquid®: Converting agricultural residues to biofuel and biochemical intermediates

sunliquid® is the technology cornerstone of Business Line Biofuels & Derivatives. With sunliquid®, agricultural residues are converted into biofuels and biochemical intermediates. First, agricultural residues such as wheat straw, corn stover, or sugarcane bagasse are treated with steam and exposed to a sudden drop in pressure, causing the straw to break down. The straw remnants enter a series of reactors, where they are liquified through specific enzymes that are produced on-site. The enzymes break down the straw into simple sugars that are fermented, generating an ethanol-water mixture. Finally, the ethanol is purified and used as biofuel or a precursor for biochemicals. The sunliquid® process is energy self-sufficient as the insoluble part of the straw, lignin, is used for energy generation.

12. Streamlining supply chain management

Business Unit Catalysts finished implementing Clariant’s end-to-end supply chain management dashboard in 2020. The dashboard offers quick diagnostics, enables root cause analysis, and provides an overview of suppliers, along with price developments, response and delivery times, as well as supplier sustainability risks.

13. Setting up the sunliquid® supply chain

Over the past three years, Business Line Biofuels & Derivatives successfully set up its supply chain in Romania. A feedstock team established long-term contracts with almost 300 farmers, ensuring stable and reliable straw supply for the operational phase of the plant. With the partnerships established so far, Clariant already secured most of the raw material required for the plant in Podari. All feedstock is certified according to the International Sustainability & Carbon Certification (ISCC) system, which indicates that feedstock is from renewable sources. Since 2019, Business Line Biofuels & Derivatives has used a digital application to support the operation of the straw supply chain. The specially designed software allows Clariant to monitor the harvest in real time and provides the Business Line with an overview of total stocks of straw bales produced and collected, as well as transportation means used. The monitoring enables process control and efficient logistics.
