The NDA government was pushing the initiative in a bigger way than the previous government, he said. "This time we want to go in a big way. The Prime Minister has already declared 'Swachh Bharat Abhiyaan'. He (PM) said by 2019 India should become Swachh Bharat. For that you need to provide toilet to each household both in rural and urban areas. This bio-toilet is something that is affordable and nature-friendly," said Naidu.
These affordable toilets would usher in revolutionary change in people's lives, he added. "The PM has also talked about building separate toilets for girls at schools. There also bio-toilet can be used."
DRDO had developed many innovative products such as high nutrition food packets, mosquito repellents, mobile water treatment plants, medical equipment, etc which were useful but government departments should promote them, he said.
"There is a need to take advantage of science and technology to better the lives of people," he said.
