There are a few different ways to make fertilizer from sewerage and poop organic waste. One way is to anaerobically digest the waste, which means breaking it down in the absence of oxygen. This process produces biogas, which can be used for energy, and a solid residue called biosolids. Biosolids can be further processed to remove pathogens and other contaminants, and then used as fertilizer.
Another way to make fertilizer from sewerage and poop is to compost it. Composting is a natural process that breaks down organic matter into a nutrient-rich soil amendment. Sewage and poop can be composted with other organic materials, such as food scraps, yard waste, and manure.
Here are the steps on how to make fertilizer from sewerage and poop organic waste:
- Collect the waste. This can be done by manually collecting it, or by using a sewerage treatment plant.
- Anaerobically digest the waste. This can be done in a large tank or reactor.
- Separate the biogas from the biosolids. The biogas can be used for energy, and the biosolids can be further processed to make fertilizer.
- Process the biosolids to remove pathogens and other contaminants. This can be done by heat treatment, chemical treatment, or irradiation.
- Use the biosolids as fertilizer. Biosolids can be applied to soil directly, or they can be mixed with other organic materials to make compost.
It is important to note that there are some regulations around the use of sewage and poop as fertilizer. These regulations vary from country to country, so it is important to check with your local authorities before using this type of fertilizer.
Here are some of the benefits of using sewage and poop as fertilizer:
- It is a sustainable way to use waste.
- It provides nutrients that plants need to grow.
- It can improve soil quality.
- It can reduce the need for chemical fertilizers.
Here are some of the challenges of using sewage and poop as fertilizer:
- It can be a health hazard if not properly processed.
- It can have a strong odor.
- It can be difficult to transport and apply.
