There has been recent debate about using human faeces for
fertilizer. Centuries before, using poop to fertilize crops was common
practice. However, after the introduction of synthetic fertilizers and the
growing knowledge of public health, the practice fell away. Today, some city
wastewater treatment plants are beginning to look at what constitutes real
waste – as does the flush really mean the end of the line?
The City of Newberg utilizes a filtration system that
cleans, separates, and sanitizes solid human waste. This left over ‘sludge’
ends up as the product that could potentially end up back on your plate.
Grossed out? Don’t be. It’s a circular system that allows the food on your
table to become processed by you, passed by you to the facility, processed by
the facility, and then passed back into the food system and on your plate.
Through several scientifically sound testing mechanisms that
involve layers of filtration, high heat, and sawdust Newberg’s solid waste ends
up as organic compost perfect for smoothing around the spring garden and flower
beds. It also sells at a fraction of the price of synthetic fertilizers and is
considered totally organic. Good for the environment and your wallet? What do
you think about that?
