After it goes down, what happens next?
Shedding Some Light on Biosolids
Biosolids contain micro-nutrients such as: copper, phosphorus, iron, and zinc which are essential for healthy growth. Biosolids are very useful as a fertilizer because they: “reduce the need for regular fertilizers, reduce production costs, improve soil fertility, enhance soil structure, add organic matter that maintains good soil tilth and reduce soil erosion and runoff.”[1] As you can see, biosolids are very good for plant growth.
Now that recently we are very conscious about the environment, it’s a huge upside that recycling biosolids helps promote this. Human wastes dumped in the ocean causes the reduction of oxygen in water due to the presence of nitrogen and amino acids. This is bad for all marine life and algae are over-produced. Also, recycling biosolids reduces the amount of human wastes in landfills which is great because less land is being wasted for landfills.
If you’re worried about how healthy biosolids are, don’t, because they’ve been tested numerous times and are proven to be 100% safe and reliable. They undergo rigorous treatments and are made sure to meet standards of Ontario Ontario
Now don’t be afraid to ask the question you’ve to, the answer is, yes, they smell. However, odour is reduced because biosolids are treated in anaerobic conditions (conditions with no air), so there are slight traces of smells. Plus, odour is further reduced because of they are injected very deep into the field. Biosolids can contain pollutants, but that only depends on what the everyday citizen drops down the drain. When there’s less paint and biohazardous chemicals in the sewage, there are fewer pollutants in biosolids.
This also brings us to another bonus of biosolids, there’s less fertilizer being used. Fertilizer is good for plants, when used in moderation. Fertilizers contain harmful elements that cause excess plant growth, and can harm humans over time when washed down sewages on rainy days. Fertilizers also, like human wastes, minimize oxygen in the ocean therefore increasing algae growth and it can kill marine life.
Royal Flush
As you can see, biosolids are very good for plants and can be an effective replacement for fertilizer. So next time, don’t be afraid, BE PROUD! FLUSH IT DOWN, knowing that you’re doing a good thing, and you’ve just helped make the environment a little healthier, and a plant, a little greener. Resources:
