Are Biosolids Safe?



Biosolids has been under intense scrutiny for decades. Numerous studies have been made about it, all pointing out to the inevitable conclusion that biosolids are safe for consumption—not directly, of course. In a nutshell, what we know is that biosolids, an organic matter from the treatment of domestic wastes in wastewater treatment plants, can be used for gardening and even crop production.

Let’s delve deeper into it.

If you know about sewage sludge, then this is it. Biosolids is a result of the treatment of the sludge material that came from the wastewater. Sewage sludge are materials that cannot be treated in the wastewater treatment facility. Instead, this sludge material needs very specific and specialized treatment processes to be viable for crop production and gardening and vegetation.

So, why is it being considered safe for crop production? Biosolids are actually nutrient-rich organic materials. They contain essential plant nutrients and organic matter that are important for the growth of crops. When used for gardening, biosolids also help in the blossoming of flowers and the growth of other kinds of plants and succulents. Moreover, biosolids are also often recycled as fertilizer and as soil amendment.

When your soil is weak and is lacking of nutrients, adding biosolids in the mix will boost the much-needed nutrient level of the soil. In turn, this will make the soil viable for crop production and gardening. The presence of biosolids, in fact, reduces the need for chemical fertilizers. For farmers, this is a much-needed savings because chemical fertilizers can cause hundreds, if not thousands, of dollars, depending on the size of the farm or garden.

As one of the most studied processes in the past decades, biosolids has proven again and again its viability in the crop production industry. In fact, it has been observed rather wildly that biosolids, when treated and applied correctly, encourages sustainability of the farm or the garden. The US Environment Protection Agency approved the application of biosolids even in food production because of the nutrients it releases into the soil once it is used as organic fertilizers.

Never has there been much interest about the state of the environment, not only about climate change but about crops and even home gardening, than the past decade when we are reduced to being victims of environmental degradation. The discovery that biosolids is safe to use for food-rearing is an astonishing feat only because it finally contributes to the cycle of production, disposal, and treatment.
