High-quality co-product lignin

The process also produces natural, untarnished lignin of a quality not available on the market today and which is an enabler of entirely new products generations / applications.

applications | lx-process


The LX-Process cracks 2G biomass and can readily be adapted for large-scale 2G ethanol manufacturing but is also inversely scalable, enabling economic retrofit of smaller, decentralized biogas plants.


The LX-Process eliminates a principle hurdle faced in bio-processing, namely the presence / concentration of inhibitors, which are formed in all existing 2G pre-treatment methods.


The LX-Process produces an unparalleled quality of natural lignin as a co-product. This quality is not available today and promises to enable a host of new, disruptive technologies a variety of areas.

2G Biofuels

  • Biogas plants only metabolize the starchy portion of the feedstock. The leftover digestate commonly ends as fertilizer
  • The LX technology cracks the fibrous portion of the leftover digeste, resulting in complex sugars available for fermentation
  • Yields of commonly used feedstocks can be increased by up to 50%, depending on the feedstock
  • More importantly, 2G substrates such as agricultural residues (wheat/rice/raps straws, EFBs) can be used instead, with comparable yields and much lower costs
  • Economics are very compelling in industrial scale projects
  • Retrofit of existing biogas plants possible on a modular basis
  • Operates at low temperatures (~70°C), enabling use of residual waste heat
  • Additional value uplift achievable from high-quality lignin as co-product, see below
  • Highly favorable ecological impact (“food vs. fuel”)

2G Biochemicals

  • Bio-based manufacturing processes using 1G feedstocks are rapidly developing for chemical intermediates
  • Bio-based chemicals are “drop-in” replacements for their petrochemical counterparts (i.e. 1,4 butandiol, succinic acid, acrylic acid and adipic acid
  • Unique bio-based chemicals (i.e. without a petrochemical equivalent) are also developing, with polylactic acid (PLA) already finding widespread usage today
  • The LX Process is an enabler of 2G bio-based chemicals:
    • Virtually inhibitor-free and amorphous, LX cellulose eliminates the need for expensive, custom-tailored enzymes for hydrolysis
    • Ideal platform for 2G fermentation strategies, i.e. an enabler of CBP (“combined bio-processing”) environments
    • Every downstream value chain profits immensely from the ability to flexibly use 2G feedstocks
    • Economics highly compelling – the technology is even suitable for lower volume biogas environments
    • Value uplift from high-quality lignin as co-product, see below

Natural Lignin

  • Natural lignin is a non-toxic, extremely versatile and highly abundant raw material with excellent adhesive and dispersant characteristics
  • Lignin available in the market today is mostly tarnished and of a low quality, i.e. different pre-treatment processes chemically alter the lignin and leave impurities (sulfur, carbohydrates) and inhibitors (i.e. furfural, 5-HMF, formic acid) that cannot be economically removed
  • The LX process produces a virtually unparalleled grade of soluble, sulfur-free lignin with very little residual carbohydrates!
  • An abundant and economical supply of natural lignin will revolutionize industrial applications in areas such as phenolic resins, plastics and adhesives
  • Furthermore, it will enable entirely new generations of disruptive products. An example – 100% bio-based ink for 3D printing, a project LXP is already working on.

LX Pretreatment Process

  • Lignin is the complex polymer responsible for the woodiness of plants and typically accumulates over time, filling the space between the cellulose strands and imparting the plant the strength to grow larger (in many ways similar to the role that concrete fills in a steel-reinforced structure).
  • The patented the proprietary “LX-Process” essentially cracks the lignin strands, exposing the cellulose and hemicellulose, both of which are essentially complex sugars, and makes all three components available and separable for further processing.
  • Technically, the LX-Process involves a chemical pretreatment cycle at normal atmospheric pressure and low temperatures (ca. 70°C), followed by precipitation of the cellulose and lignin and separation / filtration of each component.
  • The low temperatures make the technology perfectly suitable to take advantage of residual waste heat.
  • Low temperature and pressure allow for a virtually unparalleled grade of soluble, sulfur-free lignin with very little residual carbohydrates.
  • In total, 26 patents have been issued and 17 more applied for globally.
