On sanitation, I applaud every effort, also yours! However, it would be good to realize that our poo has useful nutrients in it as well. So why not go for safe ways to promote health ánd give back to nature her so desperately needed nutrients? Indonesia has lots of degraded soil to regenerate before it can unleash the abundance of nature again. And water can be used for better things than to be polluted with septic tank chemicals.
So, my suggestion? Compost toilets are very safe. Helofyte filters are very safe. We need solutions that keep us within the boundaries of our planet. And I hope all our efforts will go to humans ánd the planet or there will be no place to live for us anymore…
