From aquaculture waste to commercial products in less than 24 hours
Biomass from land-based or closed aquaculture facilities has the potential to become valuable products. For example, land-based aquaculture facilities generate fish waste, feed residue and faecal matter, the total of which represents a significant volume of waste.
Our solution makes it possible to process the sludge into a high-value and commercial protein.
The explanation is simple: A Hyperthermics plant uses heat-friendly bacteria from the earth's interior. This permits a working temperature of 80°C – much higher than other solutions. Thus, the conversion time from sludge into protein powder is reduced to less than 24 hours.
Compact dimensions, large capacity
Because Hyperthermics plants are so effective, they also need less space than conventional plants. Compact design is part of the idea. The plants are tailored in accordance with the customer's requirements.
During the production of protein from fish sludge, a proportion of biogas is also generated. This can be harnessed as energy for operating the plant. Hyperthermics' solutions are excellent energy exchangers with, for example, a RAS facility.
Application of protein powder
The high-value protein powder is filtered, dried and packed in big bags on site. There is a demand for the powder as an ingredient in feed for pets, for example.
Hyperthermics' solution makes an important contribution to increased sustainability in aquaculture and provides a competitive edge in terms of reduced net production costs by up to NOK 1.50 per kg produced salmon.
Notice: Hyperthermics plants are also relevant for dairies, breweries and other industries generating organic waste.
Protein plant
In this setup, the primary product is high-value protein mass. It is possible to extract one tonne of protein mass from one tonne of biomass. In this context, the biogas is a by-product that can be used as an on-site energy source.
The biomass comprises faecal matter from fish and feed residue. The cultivation of bio-organisms (single-cell proteins) at the Hyperthermics facility increases the protein content of the biomass.
Biogas plant
The purpose of this setup is to convert waste into biogas and fertiliser. The entire biogas potential is harnessed and can be completely or partially included in the operation of the aquaculture facility. The hygienised and stabilised fertiliser may be sold on the open market.
This solution is particularly favourable if there are problems disposing of fish waste, in addition to faecal matter and feed residue. The method reduces bio-residue by up to 80%. This means reduced transportation and disposal costs.
Dual protein and biogas plant
A large, land-based aquaculture facility, for example, will have a sufficient volume of biomass for the profitable production of both high-value protein mass and biogas.
This setup is a fusion of the two setups described above. The upper part produces biogas and fertiliser from fish waste, for example. The lower part produces high-value protein mass from faecal matter from fish and feed residue. Residual products from the latter are then transferred to the biogas reactor and converted into biogas.
