We live in a consumer’s society. We buy more, use more, produce more and eventually – throw away and dispose of more. The unwanted stuff, the undesired byproduct of our daily consumption, needs to be disposed of, taken away from our eyesight, our immediate environment and our comfort zones.

But we want to be more “green," so we recycle, compost, buy sustainable, eco-friendly, local, organic, and all natural products, but at the end of the day, we are all producers of sludge, aka "biosolids."

Population Growth and Waste

And there are more and more of us. The growth of human population is unsustainable. Like a bacterial colony on the petri dish, we continue to multiply, eating through the finite amount of “stuff” available to us until we deplete all the available resources and produce enough waste that the whole colony will collapse. The question then of what to do with the waste becomes the question of survival.

What do we do with the waste produced by the population growing at the increasingly rapid pace, consuming more and more resources, and producing increasing amount of hazardous waste?
