The truth is, it’s very easy to get to know biosolids and understand what it can do for the environment and the humanity at large. In the interest of informing more people than ever before, here are a list of the frequently asked questions regarding biosolids.

What are biosolids?

Biosolids refers to the domestic waste that has been treated by being processed in a treatment facility. These are nutrient-rich materials that can be used as organic fertilizers, paving the way for the production of truly organic food products. Biosolids maintain the productiveness of the soil and also stimulate plant growth.

What is the purpose of biosolids?

The main purpose of biosolids is to provide the needed nutrients of plants. Biosolids, especially Class A biosolids, has nitrogen, potassium, and phosphorus in large doses. These three are the needed nutrients of every plant in the planet.

Why do we have biosolids?

Biosolids is the result of treating wastewater sludge, which came from domestic waste that has been treated and processed. Sludge is the material that cannot be processed in an ordinary wastewater treatment facility. The water treatment technology was created to make the water safer for consumption, and also for recreation and seafood harvesting. It was only three decades ago when Americans would dump their waste into lakes, rivers, bays, and other bodies of water. Thanks to the regulation of domestic waste, wastewater is now being treated and recycled. The end-product, biosolids, will either be used as fertilizers or be incinerated or dumped in a landfill.

How do we use biosolids?

After being treated and processed, biosolids is applied as organic fertilizer. The controlled application of biosolids on farmland completes the natural cycle in the environment. Instead of taking up space in a landfill and other disposal facility, biosolids is turned into a valuable fertilizer.

Are biosolids safe?

When practiced in accordance with existing federal guidelines and regulations, biosolids is safe for use in crop production and even as directly applied to the environment. The National Academy of Sciences reviewed current practices, public health concerns, and regular standards in concluding the safety of biosolids usage for food production in farms.
