What can we do with Sewage?
According to certain academics and businesses, wastewater and all the other stuff that goes down the drain is a true treasure trove of chosen raw materials. It's a compelling argument from a financial standpoint. Municipalities around the world spend billions of dollars purifying wastewater and animal waste and get very little in return. Additionally, waste releases gas and nitrogen into the environment, raising expenses.
Various things we can do with sewage
1: Produce Urea: Urea, which gets its name from its presence in urine, is one of the most widely used industrial compounds on the planet. It is used to minimise emissions in plastics and motors. But, oddly enough, it's man-made. It is made by breaking methane in chemical plants.
2:Dig out the Nutrients: Phosphorus and other nutrients are extracted from wastewater and recycled into fertiliser by a number of companies.
3: Make Fish Food: The nutrients in sewage are utilised to grow organisms that feed fish. Fish food is typically generated in fresh water, but according to a study conducted by scientists from Bhubaneswar and Kolkata, sewage can help save freshwater. According to scientists, the procedure is both cost-effective and profitable.
4:Produce Pipeline-Grade Methane: It can be used to construct, run, and maintain anaerobic manure digesters that convert manure to methane. Carbon credits can be sold, and the solids can be used as cow bedding or fodder for organic flooring or building materials in the future.
5: Sanitation and renewable energy generation: A holistic strategy at the micro level – sanitation and sewer – can help to create a healthy and hygienic community while also reducing our electricity usage.
At the community level, centralised collection and waste treatment from toilets, provides not only proper sanitation, but also renewable energy if treated scientifically. Waste can be effectively treated with bio-methanation, and the biogas produced can be used as a cooking gas or to power a biogas engine to generate electricity.
The biogas-to-power concept is being applied in numerous public toilets around India. Success stories have been written on producing electricity from trash collected in public restrooms. Many other countries are following suit. In the form of waste treatment and renewable energy production, Government’s requirement for energy generation from public toilets will be remarkable in meeting our demands and contributing to sustainability.
6: Coal like production: Even human sewage can be converted into solid bio-coal for energy generation, which, if scaled up, might help align industrial carbon demand with the need to eliminate organic waste and reduce greenhouse gas emissions.
The process of hydrothermal carbonisation (HTC), which employs superheated water under pressure to manufacture bio-coal in a matter of hours, is one way to make the coal alternative. Geologically, it takes millions of years for fossil coal to form. Because it functions as a catalyst for the natural creation of coal, it's a relatively simple and stable process.
