Business model 1:
Selling feed production units

A high-density algal feed supply system that fattens weakened and immature bivalves

Bloomo answers the feed shortage and heat stress facing oyster and other bivalve producers with a steady, high-density supply of microalgae — improving yield and making seedling production sustainable.

Business Model

Context, product, outlook

Context

Export demand for oysters is rising sharply, yet bivalve production has fallen substantially through thinning caused by cleaner seas and feed shortage, and through mortality caused by rising temperatures. Keeping supply stable has become an urgent problem for the industry.

Product

Immature or weakened oysters are landed and fattened into fresh, marketable oysters on Bloomo’s high-density feed supply. The same unit also serves as a feed supply system for artificial seedling production.

Future

Better yield through Bloomo improves the operator’s margins. Seedling production that withstands climate change. Use within the cold chain optimises distribution.

Bloom Biomass Utilization

Putting the recovered algal biomass to work

Turning bloom into resource — Feed, Materials, Fertilizer

The algal biomass Bloomo recovers is not a by-product but a resource worth having. We provide the equipment and assessment methods to convert it, step by step, into aquaculture and livestock feed, biochar and carbon-fixing materials, and nitrogen and phosphorus fertilizer — turning wastewater treatment from a cost into a source of revenue.

As a feed ingredient

A high-nutrient material with 40–70 wt% protein, ω-3 fatty acids and carotenoids. Drawing attention as a fishmeal substitute.

Microalgal biomass is a high-nutrient material whose protein content reaches 40–70 wt%, and research into it as a sustainable substitute for fishmeal and fish oil is advancing[1][2]. Because it contains a favourable amino-acid profile, ω-3 polyunsaturated fatty acids, carotenoids and vitamins, it offers advantages in growth, immunity and pigmentation for bivalves, crustaceans and larval or juvenile fish[3][4].

Novelgen’s Algal Bloom Capture keeps a library of the optimal species for the characteristics of the water being treated (seawater or freshwater, temperature, pH), enabling continuous high-density supply through Bloomo. As an outcome of the SBIR Phase 3 programme it has led to test shipments of Bloom Oyster, and has entered the market-supply phase.

The biomass processing unit currently in development combines solid–liquid separation, drying and particle sizing in one, and is designed to make feed processing possible on site.

STREAM B Biomaterials

Oyster shell × biochar

A soil and water-treatment material that combines long-term carbon fixation with N₂O suppression.

Turning oyster shell calcium carbonate into a resource: we are developing LCA and MRV methodology to assess and trade oyster shells — a by-product of oyster farming — not as industrial waste but as a CO₂ resource fixed as calcium carbonate. Once a method is established to quantify the carbon fixed in the shell through biomineralisation when it is used as a concrete admixture or soil amendment, it becomes possible to realise its value as a carbon credit.

Biochar from algal biomass: pyrolytic conversion of the recovered biomass allows long-term carbon fixation. Beyond its function as a soil amendment, adding it to constructed wetlands and sewage treatment processes has been reported to suppress N₂O emissions[5][6].

STREAM C Resource recovery

Nitrogen and phosphorus fertilizer

A circular design that holds the resource in the biomass instead of losing it to the atmosphere.

Conventional biological treatment (nitrification and denitrification) reduces ammonium nitrogen to N₂ and releases it to the atmosphere. Microalgae instead assimilate NH₄⁺ directly into amino acids and protein, holding the nitrogen resource in the biomass rather than losing it to the air. Together with phosphorus, a resource at high risk of depletion, this offers the potential to turn sewage and industrial wastewater into a source of raw material for nitrogen and phosphorus fertilizer.

In continuous systems using a photobioreactor (PBR) with membrane separation (MPBR), nitrogen removal efficiency > 90% and phosphorus removal efficiency > 90% have been reported in several academic studies[7][8].
