If we’re going to compost human waste, it would be far better for the city to collect the sludge and do it, rather than expect every single individual to do it.

With the city, they can burn it and turn it to ash, and then use it for city purposes, like flowers.

Exactly. And rather than having dump trucks collecting the solid waste from every building, why not use the existing sewer system.
It uses water for transportation, a resource that can be recycled indefinitely.
I bet a sewer system is more energy efficient and less polluting than thousands of sewer dump trucks.

Leftist and environmentalists just don't care how much their solution COSTS, in money, resources and unintended consequences.
