The Solution to Sustainable Fuels
Transforming Non-Food Biomass into High-Value Fuels, Chemicals, and Materials
Patented, Low-Energy Biomass Conversion Technology
A patented, low-energy chemical platform that converts any lignocellulosic biomass into drop-in fuels and 2G fuel feedstocks, specialty chemicals, and advanced materials at ambient temperature and pressure.
SixRing™ has developed a suite of patented chemical compositions, methods, and low-energy processes to convert sustainable, non-food biomass into high-value intermediates, fine chemicals, biofuels, and advanced materials.
Unlike conventional biomass conversion technologies that rely on high temperatures, high pressures, or fermentation-dependent pathways, the SixRing™ process operates at ambient conditions. This enables lower capital costs, lower operating costs, and significantly reduced carbon intensity while preserving the intrinsic value of the biomass.
The SixRing™ process produces three primary product streams, high-purity cellulose, Lignin-Hemicellulose-Depolymerized-Organics™ (LHDO™), and sustainable chemicals. These products can be directly refined or upgraded using existing infrastructure into Sustainable Aviation Fuel (SAF), diesel, gasoline, renewable natural gas inputs, and a broad range of platform and specialty chemicals.
SixRing’s Range of Products Includes:
High purity cellulose and/or derivatives such as cellulosic ethanol
Liquid bio-crude product that is a mixture of organic molecules termed LHDO. A valuable hydrophobic bio-crude with a low viscosity, low molecular-weight liquid, high-value product, which consists of valuable fine chemicals and condensed aromatic structures with the majority in the C3 to C24 range and contains very low levels of inorganic impurities; and
High value sustainable biochemicals and other petrochemical feedstocks via the hemicellulose
AgTech Rooted in Plant Chemistry
Lignin-Derived Chemistry Designed to Integrate Seamlessly into Modern Crop Management Systems
SixRing™ products leverage naturally derived lignin, a structural biopolymer formed through photosynthesis and present in plant biomass. Developed using plant-based materials and patented ambient-condition processes, SixRing’s AgTech solutions are designed to work across seed, soil, fertilizer, and foliar applications within existing agricultural practices.

Our Mission: The Development and deployment of patented technology platforms that solve legacy technical, feedstock and economic challenges through the conversion of biomass into sustainable chemicals and fuels.
Why SixRing
Converts any non-food lignocellulosic biomass, including blended feedstocks
Operates at ambient temperature and pressure, reducing energy demand
Converts over 80% of organic matter into saleable products
Produces multiple high-value product streams from a single process
Enables drop-in integration with existing fuel and chemical infrastructure
Delivers 50–80% lower carbon intensity versus fossil equivalents
Proven at scale with a commercial-scale reactor in operation
The fine chemicals and molecules inherent in the biomass are intact and can be easily extracted from the output products – being cellulose and Lignin-Hemicellulose-Depolymerized-Organics™ (LHDO™). SixRing cellulose and LHDO can be easily upgraded to higher value biofuels such as Sustainable Aviation Fuel (“SAF”), diesel, gasoline, and platform chemicals.
