Officialdom’s eyebrow-raising answer to rising fertilizer prices in Japan

According to The Asahi Shimbun, Skyrocketing prices for chemical fertilizers have sent officials looking to other valuable, if unappetizing, resources that are readily available in Japan to help grow food.
While prices are climbing higher and higher, their search has taken them in the other direction--down. Way down.
It turns out that human waste from our sewers--the stinky stuff cities usually pay to get rid of--is an abundant natural resource, packed full of essential nutrients for plant growth, once it gets processed.
“Sewage sludge is a mine of treasures,” said an official with the land ministry.
And farmers are increasingly being priced out of getting those treasures from other sources because of geopolitics.
