CarpeJur cooperates with different organizations to create an integrated aquaculture system configuration where high water use efficiency is achieved by simultaneous farming of freshwater fish and microalgae. As a result, in our proposed system, negative externalities from the breeding of freshwater animals are replaced by value creation from wastewater and algae at least in three ways: extraction of oil from algae for biodiesel production, animal feed derived from algae leftovers, and natural fertilizer produced from fish sludge.
Additionally, algae will serve as a biofilter for fish wastewater treatment, leading to reclamation of clean water to be recirculated back into fish ponds, resulting into closed loop operation. As a result, we will achieve food, water, and energy security, economic and environmental sustainability.
CarpeJur team consists of undergraduate and graduate students with different specializations, allowing multidisciplinary approach and comprehensive solution to the problem.
Our team works with fish farmers and experts with experience in aquaculture, water and wastewater chemistry, and environmental engineering to develop a business model that can be adopted by different farms, whether it is large or small.
CarpeJur designs a business model that connects different economic systems such as fish farming, microalgae growth for biofuel, animal feed and fertilizer production into one self-sustainable circular economy that is based on such principles as circling longer and cascaded use across industries. The system consists of two main parts: fish farms and algal growth configuration.
The main beneficiaries of our circular model are fish farmers using traditional methods for fish production. Although the model is designed based on Armenian fish farmers’ example, the universal solution suggested by our project makes it applicable for any country and region. The cornerstone of our model is the efficient use of water resources in fish production, which saves limited water resources and also have valuable by products which are actually additional sources of revenues for fish farmers after running circular farming system. One of project’s biggest benefits is its small “water footprint,” which opens the door to commercial fish production in areas with limited water resources. Another environmental impact can be the encouragement of green energy production by creating a raw material for biofuel producers.
The project won a finalist award in Grand Rapids, US in Wege prize 2018 among 100 teams – further info.
CarpeJur was inspired by AEMS 2016, with the materials being very useful according to the project team.
