Discuss briefly the following:
Catalytic converter

Explanation

(a) A catalytic converter is a device that converts toxic gases and pollutants into less toxic pollutants by catalyzing redox reaction.
(b) Gases that trap the heat within the atmosphere are called Green house gases. E.g: CO, and CO
(c) About 150 liters of wastewater at an average is generated by an Indian individual daily, and a large amount of it is generated from toilets. Ecological sanitation (EcoSan) is a sustainable system for handling human excreta by using dry composting toilets. Ecosan toilets not only reduce wastewater generation but also generate the natural fertiliser from recycled human excreta, which forms an excellent substitute for chemical fertilisers. This method is based on the principle of recovery and recycling of nutrients from excreta to create a valuable supply for agriculture.
