Changing the World in 20 Seconds

Economical, environmentally friendly biochemicals and biomaterials are now a reality thanks to Sweetwater’s Sunburst™

Nanofibrillated Cellulose

Lower cost and more scalable than anything else on the market

Microcrystalline Cellulose

Low-cost MCC from nearly any biomass

Purest Native Lignin

Non-sulfonated, with minimal carbohydrates, in various formats

Clean C5-Rich Sugar

Clean C5-rich sugar that gives comparable process yields to refined xylose

Clean C6-Rich Sugar

Clean, high-performing C6-rich sugar

Mixed C5/C6 Sugar

Clean, high-performing mixed C5/C6 sugars


A Breakthrough in Biorefining

From Feedstock to Fully Deconstructed Biomass in 20 SECONDS.

In 20 seconds, SUNBURST frees 97% of C5 sugars and 20% of C6 sugars in monomeric form, producing a pumpable slurry of sugars, clean lignin, and high-value micro-crystalline cellulose (MCC). The remaining cellulose is easily accessible for enzymatic hydrolysis, or processed into additional MCC.

Sweetwoods Project

Sweetwater’s SUNBURST Technology Provides the Platform for the Sweetwoods Project in the European Union.

The Sweetwoods Project, located in Estonia, brings together a consortium of 9 international partners committed to converting 90% of a hardwood feedstock into high-value biomaterials and bioproducts.

The €43.2 million flagship plant is demonstrating the full, commercial-scale biorefinery concept, turning sustainable hardwoods into flexible foam, isobutene, biodegradable composites, performance insulation boards, and fuels.

At the heart of the project is Sunburst pretreatment, deconstructing wood into its constituents more cleanly and efficiently than any other process today.
