Usage of sewage waste to produce electricity

-
 AIM/OBJECTIVE  To produce local electricity from sewage waste.  ABSTRACT  Wastewater is the source of the growth of several anaerobic and facultative anaerobic bacteria. They have the ability to transfer electrons to an anode as a terminal electron acceptor and are thus classified as electrogenic bacteria. In this project, a microbial fuel cell MFC is used, that drives an electric current by using bacteria and a high energy oxidant such as Oxygen, mimicking chemical interactions found in nature.  HYPOTHESIS  Microbial Fuel Cell (MFC) has been described as bioreactors that convert the energy in the chemical bonds of the organic compound into electrical energy through the catalytic activity of microorganisms under anaerobic conditions. The microorganisms catalyze the anaerobic oxidation of diverse organic substance such as wastewater pollutant organic waste, organic matter in soils or sediments. The microorganisms oxidize organic compounds to CO2 with the ...

Surgical Masks (Waste Management)

 AIM/OBJECTIVE 🎯  To utilize waste surgical masks in laying eco-friendly roads. ABSTRACT � Plastic particles (polyblend) has recently been used in the making of roads. The polyblend is mixed with bitumen (used for road surfacing) to lay roads. The polyblend has the property of repelling water molecules and when it is mixed with the bitumen, this water-repelling property is increased by 3 times. COST INVOLVED � The cost involved is similar to that of laying normal roads. FUTURE SCOPE � These roads can be useful in preventing floods and unnecessary clogging of water on roads. on the other hand, one of the major concerns of the world i.e The Plastic can be recycled. After the corona virus outbreak, the usage of masks has been drastically increased and proportionately the trash has also been increased. The roads can reduce plastic waste thus reducing land pollution.  THE PROCESS ⚙ The used surgical mask is disposed of with the garbage.  It is then taken to the junkyard ...

Floating City

Introduction As the future arrives, people expect advanced technologies to live with. We (Harshit Khemani and Krish Jain of class 9-A, Birla Vidya Niketan) have come up with a concept of floating cities. How will we make these cities possible? How will they float in water? How will they be stable against waves? All your questions will be answered in this quick read. Thinking Process We will use a Hexagonal base as the base of the city. It is considered the most architectural shape because it occupies the most space compared to other polygons. Area and pressure are inversely proportional therefore, as the space occupied on the base increases, the pressure applied by the city on the water decreases. We will make a huge compartment at the bottom of the city with air-filled inside it. This compartment will be fully immersed in water. This will make the average density of the city less than that of the water. We will also heat the water of the water body to 4⁰C because at this tempera...
