Decoupled saltwater shrimp - seaweed Aquaponics (AP), TRL 4-5 to 7: We will demonstrate the technical and commercial viability of Water to Fork & pharmaceutical biostream approach with proprietary technology for: a) hyper-intensive, indoor shrimp farming cultivation tanks using vertical substrates in Cornell-type dual-drain fish tanks, b) a biological pilot reactor to produce phosphorous-rich irrigation solution from aquaculture interfacing the shrimp rearing system, and c) the macroalgae production system where seaweed will grow in vertical airlift bioreactors, illuminated by strategically placed high-efficient LEDs, ensuring a highly productive, safe, predictable and continuous cultivation of seaweed. Saltwater taken in will be recirculated many times within the shrimp production itself. When nutrient levels become too high for the shrimp, the shrimp water will be sent to the seaweed production, which will purify the saltwater via nutrient uptake for growth before returning it to the river. The demonstration system and steps for upscaling of the seaweed production will follow a business plan supported by a pharmaceutical end-user. KPIs: Up to 1.25 - 2.4 t/year of shrimps and at least 0.5 t/year of seaweed for nutra-/pharma-/cosmeceutical applications from a 100 - 130 m2 IMTA. Partners: Landing Aquaculture, NL; Paul Rye Kledal IGFF, DK with contractor Pure Algae, DK Youtube Video: Seaweed cultivation (2')

Biophenol Extraction (BPE), TRL 3-4 to 6-7: Making the process viable to the olive oil sector, optimizing it for future use, while using renewable energy for water-based extraction (avoidance of organic solvents and related air emissions of volatile organic compounds) and simultaneously treating OMWW for reuse as irrigation water. KPIs: At least 6 kg/day of bio-polyphenols for nutra-/pharma-/cosmeceutical uses from 2’500 m3/year of OMW (pomace + OMWW) with up to 3.5 m3/day purified OMWW as a co-product. Partners: MORE CoLab, PT Dropbox Video: Biophenols extraction (1.3')

Agri-Photovoltaics (RE-APV), TRL 6 to 7: APV systems allow us to overcome space constraints and increase land productivity by up to 70%. They provide additional shading and improved water productivity rendering APV to a strong tool to combat water loss through evaporation by intelligently combining operation of panel canopies with organic permaculture farming incl. the most advanced irrigation techniques resulting in considerably improved water use (which can surpass a 50% depending on the irradiation and temperatures on the land), particularly in water-stressed arid environments. Further, shading by the PV panels provides multiple additive and synergistic benefits, including reduced plant drought stress, greater food production and reduced PV panel heat stress (Barron-Gafford et al., Nature Sustainability, 2019). KPIs: Up to 26.5 t/year of certified organic crops (vegetables & fruits) from 2 - 2.6 ha of land (of which 1 - 1.3 ha control w/o PV panels) with up to 1.6 GWh/year renewable electricity from a 1 MWp APV power station as a co-product.

Desalination (DS), TRL 6 to 7: We will validate a novel technology, which is robust and environmentally compatible. The proprietary system of our DS partner is particularly suitable for RE use and does not require any pre-treatment, resulting in an outstanding water quality. As in opposite to SWRO, the brine is free of added chemicals and shall be exploited for the innovative recovery of not only table salt (halite, NaCl) but also Magnesium salts (Epsomite, MgSO4*7H2O, Shark et al., Nature npj Clean Water, 2022) instead of being rejected back to the marine body with damaging impacts on its biology. Minimal post-treatment of distillate water produced by simple blending with pasteurised brine for taste adjusted drinking water respectively with liquid fertiliser from the RE-BG and Epsom salt for irrigation water enriched with macro- and micronutrients. KPIs: Up to 174 m3/d freshwater with up to 1’500 t/y table salt and up to 165 t/y Epsom salt as co-products from an average of 22’000 m3/year of brine processed in solar saltworks (saltern) with a footprint of about 3 ha (or less if intake feed water salinity is <3.5%).

Advanced Anaerobic Digestion (AD) / Biogas (RE-BG), TRL 4 to 6-7: Prior extraction of polyphenols by BPE facilitates anaerobic digestion of olive mill pomace, which elsewise is extremely difficult to digest anaerobically. The core of the advanced AD innovation lies in the integrated combination of BPE, ultrasonic cavitation, process monitoring and control with an optical VFA sensor, and co-digestion of agri-food waste for better management of pH and C:N ratio. KPIs: Up to 40 kWe and 80 kWth with up to 487 t/y of liquid and up to 97 t/y of solid fertiliser as co-products. Partners: AIMEN, ES; DARIACORDAR, PT with contractor SEaB Energy, UK Dropbox Video: Containerised biogas digesters (0.3')

Controlled Cavitation (CC), TRL 6 to 7: Using a novel ultrasound-based technology, a configuration will be selected based on systematic lab investigations and the design of a high-power ultrasound reactor as a plug-flow system. This reactor will reduce the necessary energy demand for sonication of liquids and biomass suspensions for advanced anaerobic digestion (CC4AD), biophenol extraction (CC4BPE), and mobile (waste)water treatment services (CC-MOB) for advanced oxidation processes (AOP) and disinfection. KPIs: 6 kW all-in one trailer mounted CC unit as CC-MOB, CC4AD and CC4BPE Partners: Ultrawaves, DE Dropbox Video: Ultrasonic cavitation for advanced anaerobic digestion - CC4AD (1')
