Sustainable Materials
Sustainable materials derived from microalgae
A family of materials that turns microalgal biomass into high-performance organic fertilizer and feed, and puts bivalve shells to work as carbon storage. High environmental value, backed by LCA assessment.

Product lineup
Algal biomass fertilizer and feed
Algae Biomass Fertilizer & Feed
High-quality algal biomass harvested during the water treatment process is turned into organic fertilizer for agriculture and feed for aquaculture. High in protein and minerals, it substitutes for conventional chemical fertilizer and artificial feed.
Organic fertilizer for agriculture
A high-performance fertilizer rich in nitrogen, phosphorus and trace elements
Feed for aquaculture
A live-feed substitute high in protein and containing ω-3 fatty acids
LCA certified
Environmental load quantified from production through to use
Carbon credits
Fixed carbon tracked in a form that can support carbon credits in future
Bivalve shell carbon storage material
Bivalve Shell Carbon Material
A carbon-fixing material made from the bivalve shells generated by aquaculture. Calcium carbonate (CaCO₃), the main component of the shell, is known as a stable mineral whose crystal growth is controlled through biomineralisation[1][2], and under suitable storage conditions it may function as long-term carbon storage[3]. It can be used in construction materials and as an agricultural soil amendment, and is an asset that can support carbon credits in future[4].
Construction material and filler
Calcium carbonate used as a construction raw material and filler
Soil amendment
pH adjustment and mineral supply improve farmland productivity
Long-term carbon fixation
CaCO₃ crystals are stable long-term under suitable conditions; we are studying LCA/MRV methodology
Zero waste
A circular design that uses 100% of discarded shells as a resource
LCA-ready, and able to support carbon credits in future
LCA assessment
CO₂ emissions quantified across every step from raw material sourcing to disposal
Carbon neutral
Designed to reach net zero through CO₂ fixation and resource use
Credit-ready in future
Fixed carbon assessed by a third party in a form that can support carbon credits in future
Environmental reporting
Environmental-value disclosure reports for partners and investors
The evidence behind it
Note
The carbon-fixing capacity of shells (CaCO₃) is supported by peer-reviewed work on biomineralisation mechanisms. Assessment of shellfish aquaculture as a net carbon sink, however, differs with LCA methodology and assumptions (see Ray et al. 2018 among others), and we are developing our own LCA/MRV methodology. Quantification of long-term fixation — on the order of centuries, for instance — will be clarified through future demonstration.
