Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Mitigation: long-term and short-
term carbon dioxide sequestration
Sustainability: carbon avoided, fossil
product avoidance
Energy Storage: renewable electrical
energy to chemical fuels and
materials for long-term seasonal
storage
Carbon Cycle: to manage emissions
from synthetic fuels emissions
(although remembering carbon
avoided)
5. CCS and CCU/CDU Capacity
“To date there have been occasional pilot scale demonstration plants but no
commercial examples of adsorption processes for CO2 from low pressure flue
gas streams”.
“The largest units in operation at the time of writing are at a 110 MW scale
(SaskPower 2013) and significant additional work is needed to scale the
technology to 500 MW and beyond”.
P.A. Webley, Adsorption, 2014, 20, 225-231
9. “CO2 is unreactive”
Reaction Kinetics
dCO2/dt = -k[CO2]
[CO2]0 = 4x102 ppm air
[CO2]0 = 10-15% flue
gas (ca. 105 ppm)
Mass transfer co-
efficient?
Diffusion co-efficient?
Adsorbent
MEA 30% aqueous (7
mol/kg)
Ionic Liquids 100%
Solids 100% but can
be functionalised.
Surface area a factor.
CO2 is reactive
The concentration is less of an
issue if the rate constant is
high and the reaction is first
order in CO2. Alternatively, the
flow rate could be increased.
Better to use high reactivity to
produce a product rather than
capture and add more energy
to release the CO2
12. Capture-Free CDU
• 1.00 kg polymer sequesters 1.01 kg CO2
• 65% atom sequestration from CO2
• Produced from simulated flue gas
(12.5% CO2 in nitrogen)
Poly(methyl acrylate)
13. Conclusions
• We need to look at the CO2 Trilemma, not just the individual aspects: Direct Air Capture is key
• Capture is the major economic burden: we need to look at “capture-free” processes from air
• We will continue to use hydrocarbon fuels in transport. To complete the carbon cycle and move
towards a circular economy Direct Air Capture will be a necessity.
• Products with added-value will aid the economic argument.
• Catalyst/co-reactant activity will need to be high to counteract low concentrations
14. Conclusions
CDU will provide much needed additional
capacity, with profit, in the move towards a
low carbon economy. Direct Air Capture will
play a major role.
