Bloom Biorenewables converts sustainably sourced biomass into high‑purity lignin, hemicellulose, and cellulose derivatives using its aldehyde‑assisted fractionation technology. These biopolymers serve as functional additives—such as antioxidants, UV blockers, antimicrobial agents, white pigments, and low‑VOC solvents—that can replace petro‑derived inputs in cosmetics, homecare, paints, coatings, and polymer manufacturing while maintaining or improving performance.

Problem
Industries such as cosmetics, homecare, coatings, and polymer manufacturing rely heavily on petro‑derived chemicals and solvents, which contribute to high carbon emissions, volatile organic compound (VOC) emissions, and supply‑chain volatility. Transitioning to renewable, high‑performance alternatives is difficult because bio‑based materials often lack the required purity, functionality, or cost competitiveness.
Solution
Bloom Biorenewables converts sustainably sourced biomass into high‑purity lignin, hemicellulose, and cellulose derivatives using its aldehyde‑assisted fractionation (AAF) technology. The resulting biopolymers can be functionalized on demand to serve as antioxidants, SPF boosters, antimicrobial agents, or white pigments in cosmetics and homecare formulations. Highly crystalline microfibrillated cellulose and nanocellulose are offered as barrier‑enhancing, chemically recyclable additives for packaging, composites, and specialty papers. Bloom also supplies low‑VOC, aprotic solvents and bio‑based additives that match or exceed the performance of conventional petrochemical counterparts while reducing toxicity and emissions. By partnering with downstream manufacturers, Bloom enables the substitution of fossil‑based inputs with cost‑competitive, plant‑derived ingredients, supporting a circular material economy.
Target Audience
Primary customers are manufacturers of cosmetics, personal‑care, home‑care, paints and coatings, as well as producers of specialty cellulose, bioplastics, elastomers, resins, and adhesives seeking renewable, high‑performance material solutions.
Features
- Aldehyde‑assisted fractionation yields pure lignin polymers and hemicellulose sugars that can be deconstructed into phenolic monomers or functionalized derivatives.
- Highly crystalline, bleach‑free cellulose fibers with microfibrillated structures for superior mechanical strength and barrier properties.
- Bio‑based solvents with low VOC, aprotic, medium‑polarity characteristics and high flash points for safer chemical synthesis and formulation.
- Multifunctional additives offering antioxidant, UV‑blocking, antimicrobial, and antiviral activity, usable in polyesters, polyurethanes, adhesives, and coatings.
- White lignin pigment with 2 µm particle size, high dispersibility, and silky feel, enabling color‑sensitive applications.
- Sustainable feedstock sourcing from non‑food biomass (e.g., sawmill residues, agricultural side streams) ensuring no competition with food production.
- Compatibility with existing industrial processes, allowing direct replacement of petro‑derived inputs without equipment changes.
