New Reactor Offers Breakthrough in Organic Waste Management
Imagine a special machine called the SAAnA reactor that helps clean up trash.
It takes all sorts of yucky organic waste like food scraps and turns it into useful things.
First, it gives the waste a quick oxygen bath, then it lets it sit without oxygen to make gas that can be used as energy.
Finally, it gives it another oxygen bath, turning it into good stuff for plants.
This whole process is much faster than before, making the air cleaner and providing helpful fertilizer for farmers.
The reactor can handle many types of waste, making cities cleaner and helping the planet.
The SAAnA reactor was developed by researchers at BITS Pilani, Hyderabad Campus.
It processes organic waste in 23 days, quicker than traditional systems.
The reactor produces biogas and high-quality biofertilizer.
It can treat various organic waste streams, individually or combined.
The design is energy-efficient and suitable for urban and rural settings.
