-This section considers the environmental impact of the project using principles inspired by the butterfly diagram, a model that represents circular material flows [(ellenmacarthur_butterfly_diagram)]. The model distinguishes between biological processes, where materials safely integrate into natural systems, and technical processes, where products are maintained, reused, and recycled to extend their lifespan (See Figure {{ref>fig:Butterfly}}).+This section considers the environmental impact of the project using principles inspired by the butterfly diagram, a model that represents circular material flows [(ellenmacarthur_butterfly_diagram)].

-The MARIS HABITATS concept reflects these principles by combining long-term environmental integration with efficient use of technical components. From a biological perspective, the habitat is designed to support marine colonization over time. The use of non-toxic and durable materials allows algae, microorganisms, and small marine species to attach and grow on the structure, contributing to biodiversity enhancement [(DIPNDIVE)] .+The Maris Habitats concept reflects these principles by combining long-term environmental integration with efficient use of technical components.

-From a technical perspective, the system is designed with longevity and adaptability in mind. The modular concrete habitat structure is intended to remain underwater for long periods, while the electronic components are housed in a detachable waterproof enclosure attached to the habitat. This enclosure contains the battery, microcontroller, and data storage system. Sensor probes are mounted through the enclosure and remain exposed to seawater to measure environmental conditions such as pH, conductivity, pressure, and temperature. This modular design allows maintenance or replacement of electronic components without removing the entire habitat structure.+From a technical perspective, the system is designed with longevity and adaptability in mind.

 Maintenance requirements are reduced through the use of durable materials that can withstand harsh marine conditions. When maintenance is required, divers can retrieve stored data and replace batteries without disturbing the reef structure. This reduces unnecessary material replacement and extends the operational life of the system. Maintenance requirements are reduced through the use of durable materials that can withstand harsh marine conditions.

-For the prototype, conventional concrete may be used to reduce costs, while the final design uses basalt fiber-reinforced concrete to improve durability and corrosion resistance in marine environments. This approach reduces environmental impact while maintaining long-term functionality.+For the prototype, conventional concrete or 3D printing may be used to reduce costs, while the final design uses basalt fiber-reinforced concrete to improve durability and corrosion resistance in marine environments.

-The economic aspect of MARIS HABITATS is mainly related to the long-term benefits created through ecosystem restoration and its integration with existing marine infrastructure. By improving marine biodiversity and supporting fish population growth, the system may help increase fishery productivity over time. This can create economic benefits for coastal communities that depend on fishing as a source of income and food.+The economic aspect of Maris Habitats is mainly related to the long-term benefits created through ecosystem restoration and its integration with existing marine infrastructure.

 Previous studies have shown that artificial reefs can increase fish biomass and support the development of fisheries, which can lead to economic improvements in coastal areas [(Artificial reef preparation)]. In this project, this idea is applied through habitat structures that provide shelter and breeding areas for marine species. Previous studies have shown that artificial reefs can increase fish biomass and support the development of fisheries, which can lead to economic improvements in coastal areas [(Artificial reef preparation)].

 In addition, the project can benefit from collaboration with public institutions, research organizations, and environmental programs. Marine restoration and biodiversity protection are increasingly supported by sustainability policies and funding initiatives [(DEUTZ2020)]. This creates opportunities for financial support through grants and public-private partnerships. In addition, the project can benefit from collaboration with public institutions, research organizations, and environmental programs.

-Although the initial investment may be relatively high, the project can create long-term value through ecosystem restoration, fishery support, and improved coastal protection [(COSNTANZA2014)]. For this reason, MARIS HABITATS can be considered both environmentally sustainable and economically viable in the long term.+Although the initial investment may be relatively high, the project can create long-term value through ecosystem restoration, fishery support, and improved coastal protection [(COSNTANZA2014)].

-The project contributes to social sustainability by supporting marine ecosystems that are important for coastal communities and fisheries. Healthier fish populations can improve food security, support local fishing activities, and contribute to local economic stability. 
  
 The integration of environmental sensors also creates social value by generating data that can be used by research institutions and environmental organizations for marine monitoring and scientific research. This can improve understanding of marine ecosystems and support better environmental decision-making. The integration of environmental sensors also creates social value by generating data that can be used by research institutions and environmental organizations for marine monitoring and scientific research.

-In this project, the material phase focuses on choosing durable and environmentally responsible materials. The final design uses basalt fiber-reinforced concrete. Basalt fibers are made from natural volcanic rock and are known for their resistance to corrosion and chemical stability in seawater, which makes them suitable for marine environments [(FIORA2015)]. Electronic components, including the microcontroller, were also selected based on energy efficiency, reliability, and expected lifespan.+In this project, the material phase focuses on choosing durable and environmentally responsible materials.

 During the manufacturing phase, the reef structure is produced through concrete casting, while the monitoring system is assembled separately as a detachable smart block. This smart block contains the battery, microcontroller, SD card, and sensors. Keeping the electronic components separate helps avoid embedding electronics directly into the permanent structure and reduces unnecessary material waste. During the manufacturing phase, the reef structure is produced through concrete casting, while the monitoring system is assembled separately as a detachable smart block.

-To reduce environmental risks, the smart block can be removed for maintenance, battery replacement, data collection, or repairs without disturbing the main reef structure. Separating the electronic components from the permanent habitat also helps reduce the risk of long-term marine pollution.+To reduce environmental risks, the smartlogger is designed as a removable unit that is not cast into the main reef structure. It is mounted on a separate support frame and secured to the module block with a chain, which keeps the smart box connected to the reef structure and gives the diver a clear point to attach a hook or line. During maintenance, battery replacement, data collection, or repairs, only the smart box is lifted from the seabed, while the main reef structure stays in place. This also helps reduce the risk of long-term marine pollution from electronic components.
  
 At the end of its life cycle, the structure is intended to remain in the marine environment and continue functioning as an artificial reef that supports biodiversity [(SELLA2015)]. Electronic components can be removed and reused in future systems, which helps reduce waste. At the end of its life cycle, the structure is intended to remain in the marine environment and continue functioning as an artificial reef that supports biodiversity [(SELLA2015)].
