Vermi refers to small worms such as earthworms. Vermi-processing toilets are those toilets in which humans excreta is treated by earthworms. It has been found to be a novel, low water-use toilet for safe processing of human excreta without odour and fly problem. The operation of the toilet is very simple and hygienic. The human excreta is completely converted to vermi cakes - a resource much needed for enhancing the fertility of the soil.
We should not throw chemicals like paints, solvents, insecticides, motor oil, medicines down the drain as they may kill microbes that help purify water. It also leads to pollution of groundwater and may adversely affect the health of organisms.
