During digestion and during function of our cells our cells produce some toxic substances and which is very important to throw them out otherwise we face a lot of problems. The journey of our waste is very simple. It goes from our toilet to a very big tank where there are millions and billions of anaerobic bacteria which really eat our waste and convert them into very simpler compounds and the most helpful work they do is that during eatation of waste biogas is produced which is essential for electricity production and other industrial things.
