Should toilet paper be thrown into the toilet after using the toilet or where?

I think we should throw it directly into the toilet, firstly to reduce the generation of solid waste, and secondly to reduce the growth of bacteria in the toilet. I originally wanted to see if any experts in environmental protection could give a more scientifically based answer, but if I didn’t see it, I’ll tell you myself. As a girl who majored in environmental science and is now engaged in the environmental impact assessment industry, she has a certain say~ Toilet paper is generally soluble in water, especially toilet paper produced in Japan, which may be more easily degraded by water. It is not a worship of foreign countries. It’s foreign, but in terms of environmental protection, Japan is a pretty good country in the world. Since toilet paper can dissolve in water, why bother throwing it into a paper tube? If left in the bathroom, there will be odor, bacteria may spread into the air, and solid waste will be produced, increasing the cost of garbage removal. I would like to say a few more words. Putting toilet paper into water will increase the concentration of suspended matter in the original domestic sewage. Compared with feces, this concentration should be considered low enough. There is no need to worry about adding more sewage treatment plants. processing costs. Okay, so much nonsense, I just want to say, just put the toilet paper directly into the toilet and let it be flushed away with the feces and urine! Of course, sanitary napkins still have to be put into the wastebasket, otherwise they will get clogged!
