Organic Fertilizer


Organic Fertilizer

While many people think only of the clean, treated water we discharge, AlexRenew’s wastewater treatment processes produce another equally important product: biosolids.

What are Biosolids?

In addition to reducing pollutants, AlexRenew reuses all available resources in our processes to create a sustainable operation that saves money and reduces greenhouse gases including our biosolids.  Biosolids are a safe, beneficial and a nutrient-rich agricultural product – especially rich in nitrogen and phosphorus. This organic matter is the result of wastewater treatment and the solids we remove and treat through pasteurization and anaerobic digestion. These processes eliminate harmful pathogens and minimize odors.

Just like the clean water we produce, biosolids are regulated by the Commonwealth of Virginia. Thanks to our award-winning management system, AlexRenew’s biosolids are Class A Exceptional Quality biosolids – the highest level possible.

A Local and Renewable Resource

Through our treatment process, we create an environmentally friendly product that is nutrient-rich and more eco-friendly than chemical fertilizers. Biosolids add organic matter to enrich depleted soils, improve soil structure and add fibrous matter to improve the soil's ability to hold water.

We provide 6,000 tons, (the equivalent of the weight of 3000 cars) of nutrient-rich byproducts from our water cleaning process to 30 farms in 15 counties in Virginia as an inexpensive and safe alternative to chemical fertilizers. Our biosolids are pasteurized and pathogen-free so they are pure and safe when they are spread in the fields. 

Transforming a waste product into a valuable resource benefits the environment and our community, our city and our waterways
