We reduce the environmental impact of salmon farming through the controlled extraction of accumulated organic matter, such as food waste and feces, without disturbing the marine ecosystem.
Our technology works with precision to prevent extracted sediments from dispersing back into the water, ensuring effective cleaning without environmental harm.
Each operation lasts between 2 to 4 weeks per site, allowing for deep cleaning in a short period of time without interrupting operations.
Rely on a validated solution that helps meet strict environmental regulations and supports regulatory audits.
Our innovative technology offers a sustainable solution for cleaning sediments without disturbing the marine ecosystem.
The unit is accurately positioned in critical areas using GPS and underwater cameras.
Sediments are removed with a balanced water flow that prevents resuspension.
Fine organic matter is extracted without affecting sand or gravel.
Water is returned to the sea and sediments are stored for reuse.

See the dramatic improvement in seabed conditions before and after SMC Cleaner treatment
After treatment with SMC Cleaner, the seabed reveals its natural state: clean sand, seashells, and signs of benthic life reappear. This visual transformation demonstrates the effectiveness of the technology in removing accumulated organic matter and restoring the ecological balance of the underwater ecosystem.
Our technology has been validated through various projects across Japan.
Collaboration on projects supported by Japan's Ministry of Land, Infrastructure, Transport and Tourism.
Implementation of SMC technology in initiatives supported by the Kagoshima Government.
Application of SMC Cleaner in projects developed with the Fukushima Government.
Participation in environmental programs in collaboration with the Nagasaki Government.
Joint efforts with the Okinawa Government for marine seabed cleaning interventions.
Projects developed in cooperation with the Tokyo Government.
The SMC Cleaner technology, validated in Japan, is in the process of being introduced in Chile with the support of Ohishi Construction and the Chilean team.
Support for the feasibility study in Chile.
Japan is the second-largest buyer of salmon from Chile.
Japan is not only a key trading partner but also aims to promote technological solutions that contribute to the sustainable development of Chile's salmon industry.
We transform sediments into valuable resources: the extracted sludge is transported to specialized plants for processing into fertilizer or biogas.
Utilizing processed sediments as nutrient rich fertilizers for agriculture, creating sustainable soil amedments.
