"CEO" Citrus reticulata Ecoenzyme: Renewable Energy Production from Ozone to Reach SDGs 2030
Explain your idea in details:
CEO made from citrus wastes which contain high organic acids, like tangerine rinds, molasses, and water, based on 3:1:10 ratio. Citrus wastes and molasses are fermented for 3 months by the microorganism. Microorganism as the fermentation agent will change substrates to be other products. In the beginning, fermentation in partial anaerobic condition will produce ozone gas enzymatically. The ozone will be detected by the cathode and reacts with the electrons from the anode to generate an electric voltage as energy. The cathode is made of aluminum (Al) which can be obtained from waste of cans, while the anode is made of carbon-based (C), due to its inert (unreacted) character, so the water will react in the anode to oxidize, also it is easy to use and affordable. 1 mole of ozone (O3) will give out 2.075 V for the voltage. The voltage is then passed through 3 resistances, arranged in series with total resistance, 3 , and the current will be as much as 0.692 Ampere. With the P = VxI equation and household voltage around 220 V, the energy conversion will yield 152.24 Watt/mol O3. It shows that every 1 mole of ozone can produce energy in 152.24 Watt. This power from CEOs ozone through the electrochemical cell connecting to the electrical circuits in series can generate household electricity without emitting greenhouse gasses. After one month, production of ozone will decrease, since it depends on organic acids and glucose. Glucose and organic acids will decrease because of its conversion to other substances like ethanol. After 3 months fermentation, the eco-enzyme solution will be separated as a solute and solid phase. The solute phase will become liquid cleaner since it has enzymatic activity and ethanol that act as removers. The solid phase will become compost, for fertilizing plants and soil.
Expected impact of your idea on sustainable development
This idea can be implemented in every house in the world, especially in Banyuwangi as the center of Citrus reticulata production. It will grow lots of potentials in Banyuwangi, not only introduce Banyuwangi to the world but also help Banyuwangi and other cities to reach Sustainable Development Goals 2030. CEO is made from citrus wastes as the substrate in eco-enzyme solution. The use of citrus wastes with molasses from the waste product of confectionery or sugar industry will become a step to achieve the sustainable management and efficient use of natural resources through reducing food and agriculture product losses along production and supply chains, including post-harvest losses. It also helps to integrate the ecosystem and biodiversity values through reducing waste generation. The formation of ozone gasses from the reaction in CEOs solution will be detected by the cathode and react with electrons from the anode to generate an electrical voltage. In conversion into electrical power, the CEO project will reach the SDGs no. 7. It will be an economical, easy-to-use, effective, and efficient alternative energy to replace fossil fuels by supplying modern and sustainable ozone energy and ensuring that ozone energy is affordable and reliable. The CEOs mechanism of energy conversion is also eco-friendly since it produces ozone to generate the household electricity without emitting greenhouse gasses. Therefore, the implementation of CEO will lead both developing and developed countries to reduce the climate pollution and manage the climate change effects. The renewable ozone energy for electricity can be used in a large-scale, and help the city which implements it, by improving the innovative sustainable infrastructure of community and industry. We can conclude, CEO focuses on achieving SDGs 2030: Clean and Affordable Energy and Climate Change, also related to SDGs Innovation and Infrastructure, Sustainable Consumption and Production, and Life on Land.
Plans for implementation and sustainability
The idea of CEO came from a question: how to utilize citrus wastes in Banyuwangi? Therefore, at the first implementation, CEO will focus on citrus wastes in Banyuwangi and be actualized there first. The CEO project requires some professionals and various parts of society. We aim to collaborate with researchers from multidisciplinary knowledge since the project based on biochemistry, chemistry, engineering, and physics. The researchers will help us to determine the amount of ozone from reactions, occur in CEOs solution with 3:1:10 ratio and find the optimal condition to produce optimal ozone. Then, the prototype of CEO can be studied more to generate the more power for electricity. Chemistry and physics research will help to know the efficacy of aluminum-carbon as cathode-anode materials for the electrochemical cell in CEOs system, also to identify the formulation of resistances, current, and voltage to optimize energy production. Engineering research can help in identifying the correct materials of electrical circuits in CEOs system to convert the voltage of ozone reaction from electrochemical cell to electrical power, and studying more how to connect the CEOs system to the household electricity and its power controls. Since CEO is made of the agriculture waste products, we need citrus farmers and citrus industries to make sure and maintain the sources of citrus wastes, then confectionery or sugar industries for maintaining the sources of molasses. Next, private sector and government are needed to support CEO on financial side through grants or collaborations. The CEO project also need youths, non-governmental organizations, and environmental activists to promote and collaborate with stakeholders in society and make real the CEO project. From those collaborations, this project will give the sustainability of energy source for household, manage the local wastes from industrial production, improve the economy and infrastructure of the cities that implement the CEO.
CEOs team consists of Salma Dienta Salsabila, Imelia Dewi, and Akhmad Amron Syahdani. They are undergraduate students of Bogor Agricultural University, Indonesia, concern in Biochemistry (Salma-Imel) and Agronomy-Horticulture (Amron) majors. They made a conceptual renewable energy idea that can be implemented in Indonesia as home country and then spreads all over the world. The idea itself is eco-friendly, easy-to-use, effective, and efficient to replace fossil fuels for electricity and also help the world to reach SDGs 2030. They also hope from this idea, they can inspire the young generations to focus on SDGs 2030. Salma as a leader was born in Bogor, 4th May 1999. She has been interested in natural science.
