Explanation:

Statement 1: Some toilets use earthworms to decompose faecal matter and kitchen organic waste using earthworms.
• Vermi-processing toilets have been field tested for many years in India and found to be a novel low water-use toilet for safe processing of human excreta without odour and fly problem.
• The human excreta is completely converted to vermi cakes — a resource much needed for soil.
Statement 2: There is no heating element and the system is not intended to operate above 35 °C, to protect the worms. The process depends more on soil organisms and worms rather than on the thermophilic microorganisms for composting.
