Introduction

The algae biorefinery concept represents the most advanced and economically sustainable approach to microalgae and macroalgae industrial utilization, one in which a single algal biomass input is systematically fractionated and converted into multiple high-value product streams, including proteins, lipids, pigments, polysaccharides, and biomass residues, maximizing the total value extracted from each kilogram of biomass and creating diversified revenue streams that together justify the economics of large-scale algae production. Kerone’s Algae Biorefinery is a complete, integrated facility designed to receive and process algal biomass through a cascading series of extraction, fractionation, purification, and conversion operations to produce a portfolio of marketable products simultaneously from a single biomass input. Inspired by the petroleum refinery model but built on the principles of green chemistry and sustainable biotechnology, Kerone’s algae biorefineries are customized to each client’s specific biomass source, target product portfolio, available infrastructure, and commercial objectives.

Why Choose Kerone Algae Biorefinery

Kerone’s ability to design and deliver algae biorefineries stems from its integration of expertise across multiple engineering and scientific domains — bioprocess engineering, thermal processing, solvent extraction, biochemical purification, and industrial automation — making it one of the few engineering companies capable of delivering a truly integrated biorefinery as a single, coherent industrial system rather than a collection of separately procured pieces of equipment. Kerone’s biorefinery design philosophy prioritizes cascading extraction — ensuring that each product stream is extracted in sequence from highest to lowest value, with each step building on the preceding one without destroying downstream product potential. The company’s engineers work closely with clients to develop optimized extraction sequences, separation protocols, and product quality targets, supported by a strong network of analytical and biotechnology partners who contribute specific expertise in pigment characterization, protein fractionation, and lipid analysis.

Types and Features of Algae Biorefinery

Kerone’s Algae Biorefineries encompass complete processing systems including: biomass cultivation and harvesting integration; primary cell disruption (bead mill, high-pressure homogenizer, or enzymatic); aqueous two-phase or solvent extraction for lipid and pigment recovery; membrane filtration for protein and polysaccharide fractionation; spray drying or freeze drying for high-value product finishing; downstream purification by chromatography or crystallization for pharmaceutical-grade products; and anaerobic digestion or pelletization of extracted residues for energy or fertilizer use. Biorefinery configurations are customized for target product portfolios including: astaxanthin + protein + lipid (from Haematococcus); phycocyanin + protein + carbohydrate (from Spirulina); EPA/DHA oil + protein + carbohydrate (from Nannochloropsis); and beta-carotene + oil + protein (from Dunaliella salina).

Frequently Asked Questions (FAQ)

  • An algal biofuel plant is focused primarily on converting algal biomass into fuel. An algae biorefinery takes a broader approach, extracting multiple high-value products (pigments, proteins, lipids, polysaccharides) from the same biomass in a cascading series of extractions, significantly improving the overall economics of algae production.
