The process is used to stabilize wastewater solids prior to their use as a soil amendment or mulch in landscaping, horticulture, and agriculture. Stabilization of wastewater solids prior to use destroys pathogens (disease causing organisms), minimizes odors, and reduces vector (e.g., flies) attraction potential.

What are biosolids and what are they used for?
Biosolids are the nutrient-rich organic materials resulting from the treatment of domestic sewage in a wastewater treatment facility (i.e., treated sewage sludge). Biosolids are a beneficial resource, containing essential plant nutrients and organic matter and are recycled as a fertilizer and soil amendment.
What is biosolid waste?
Biosolids: mix human waste with toxic chemicals, then spread on crops. ... This â€śbiosolidâ€ť sludge is expensive to dispose of because it must be landfilled, but the waste management industry is increasingly using a money-making alternative â€“ repackaging the sludge as fertilizer and injecting it into the nation's food chain.
Are biosolids safe to use?
Because it is made from treated sewage, it's considered safe for use as fertilizer or land reclamation, and about 50% of all biosolids produced in the U.S. are being used as fertilizer, though only about 1% of cropland has biosolids applied. ...
What is the difference between biosolids and sludge?
â€śSewage Sludgeâ€ť refers to the solids separated during the treatment of municipal wastewater. â€śBiosolidsâ€ť refers to treated sewage sludge that meets the EPA pollutant and pathogen requirements for land application and surface disposal. ...
Are biosolids human waste?
Spreading biosolidsâ€”which include human and industrial wasteâ€”on farmland helps cut down on synthetic fertilizer. But it may also pollute water supplies and expose people to harmful chemicals.
Is human poop good for plants?
The use of unprocessed human feces as fertilizer is a risky practice as it may contain disease-causing pathogens. ... The safe reduction of human excreta into compost is possible. Some municipalities create compost from the sewage sludge, but then recommend that it only be used on flower beds, not vegetable gardens.
Do farmers use human waste?
For decades the waste recovered from water treatment works has been reprocessed and sold to farmers as agricultural fertiliser. ... However, regulations which exist throughout the UK mean that before sewage sludge is sent for use in agriculture it is tested for a series of heavy metals, including mercury, zinc and copper.
What is human waste sludge?
Terminology. The term "human waste" is used in the general media to mean several things, such as sewage, sewage sludge, blackwater - in fact anything that may contain some human feces. In the stricter sense of the term, human waste is in fact human excreta, i.e. urine and feces, with or without water being mixed in.
Is it safe to use compost made from treated human waste?
In the home garden, composted human waste is considered to be unsafe for use around vegetables, berries, fruit trees or other edible plants.
What are the advantages of using biosolids as a fertilizer?
Biosolids improve soil by enriching it with â€śslow releaseâ€ť organic matter â€” preferable to synthetic fertilizers. Biosolids increase plant growth by providing nitrogen, phosphorus, potassium, zinc, and other nutrients critical for healthy plant growth.
Is human waste hazardous?
Human and animal feces/urine are bio-hazardous waste, and sanitizing a home or business that has been exposed to these materials requires expert help. ... If not treated professionally, human and animal feces/urineâ€”and other body fluids like blood and vomit can cause diseases and spread viruses.
Do organic farms use biosolids?
And sewage sludge is already sprayed on conventional farm fields across the U.S. The only sector of agricultural land restricted from using biosolids is that of certified organic farms.
Do biosolids smell?
Most odors in biosolids are caused by sulfur compounds that only cause toxic effects in concentrations vastly greater than that which triggers a smell. Further, gases with a possible toxic effect are not present in biosolids in concentrations that would endanger nearby residents.
What happens to sewage sludge?
Sewage sludge is a product of wastewater treatment. ... Once treated, sewage sludge is then dried and added to a landfill, applied to agricultural cropland as fertilizer, or bagged with other materials and marketed as â€śbiosolid compostâ€ť for use in agriculture and landscaping.
Where do biosolids come from?
Biosolids are a product of the wastewater treatment process. During wastewater treatment the liquids are separated from the solids. Those solids are then treated physically and chemically to produce a semisolid, nutrient-rich product known as biosolids.
Is humanure legal?
And as long as your compost pile is neat and reasonably odor-free, you shouldn't be subject to any municipal nuisance laws, either. However, selling your humanure compost is definitely illegal, so don't do that.
Can you eat tomatoes grown in human waste?
We, who work in the wastewater sector, all know that the seeds of tomato are not digestible. They are resistant, so they pass through the human body first, and then pass through the screens, being small enough.
Does China use human feces as fertilizer?
Human waste is used as an agricultural fertilizer in China and elsewhere. Because the eggs of many helminth species can survive in environmental media, reuse of untreated or partially treated human waste, commonly called night soil, may promote transmission of human helminthiases.
Can I pee on my compost pile?
Urine, too, is a great compost stimulator. Obviously, the stiff shot of nitrogen and a bit of moisture both help, and the uric acid (urea) is also very beneficial. Uric acid levels are said to be the highest in the morning, so that's the best time to rain down on the compost pile.
Can human feces be composted?
Human waste is normally a â€śnoâ€ť for the general home compost bin. However, if properly managed, human waste can be properly composted. A composting toilet can turn your poop and other organic material into compost that is just about ready to use.
What animal poop is the best fertilizer?
Rabbit poop wins the prize as the most concentrated herbivore manure. Rabbits don't produce poop in the quantity of larger animals, so consider it a special commodity and use it sparingly on vegetable seedlings as a nitrogen boost. Soak rabbit poop in water for 48 hours and apply as a dilute liquid fertilizer.
