Before using biosolids and Class A organic soil in your gardens, ranches, and farmlands, you need to understand anything and everything you can about biosolids, compost, sewage sludge, and the treatment process that is required to turn waste into fertilizers.
Here is more information about biosolids, which can help you better understand why this is being pushed by the United States Environmental Protection Agency (EPA):
- Sewage sludge is being used in EPA regulations, which was made and completed to regulate and manage the use and the disposal of sewage sludge. This framework is being used to protect humans from consuming products from untreated sewage sludge. The regulations allow for sewage sludge to go through a separate treatment process that could turn it into Class A organic soil.
- The terms biosolids and sewage sludge can be used interchangeably. Do not be confused if the EPA regulations use biosolids or sewage sludge sometimes. This is also true with other journals, blogs, and articles about biosolids.
- Biosolids are rich in nutrients needed by plants and crops to grow. Biosolids are not always used in home gardens, but they are proven safe for crop production. Biosolids is an organic matter that was derived from treating wastewater sludge in treatment facilities. It is important to note that a separate treatment facility handles wastewater sludge. Solids are treated in a much simpler facility.
- Biosolids is recyclable. This is the reason why the EPA recommends the use of treated wastewater sludge for the growth of crops. It contains important nutrients usually found in commercial-grade fertilizers. The use of biosolids eliminates the need for fertilizers and thus, makes it more cost efficient than buying and using chemical fertilizers.
- When biosolids is treated and managed properly, harmful materials are prevented from being released to bodies of water. Remember, our waste simply goes to the ocean through streams, rivers, and even lakes. The proper treatment of wastewater sludge allows for the passing of biosolids through these streams. Though they used to be waste, the treated form will not harm water bodies.
Biosolids is an important development in the developed world. There might come a time when chemical fertilizers are no longer viable because sewage sludge will now be treated as organic soil material capable of bringing the nutrients plants need from commercial fertilizers. That’s why when you see waste and other household garbage, do not think of them as nothing. These can possibly go back to you in another form—through fertilizers in your food.
