Introduction to Milorganite
Milorganite is a brand name for a type of fertilizer that has been in use since 1926. It is produced by the Milwaukee Metropolitan Sewerage District (MMSD) in Wisconsin, USA. The fertilizer is known for its slow-release properties, providing nutrients to plants over an extended period, which can lead to healthier growth and development. Milorganite is widely used by gardeners, landscapers, and farmers due to its effectiveness and environmentally friendly production process.
History and Production Process
To understand whether Milorganite is made from human waste, it’s essential to look at its production process. The fertilizer is produced from biosolids, which are the nutrient-rich byproducts of wastewater treatment. The process begins at the wastewater treatment plants in the Milwaukee area, where sewage and other wastewater are treated to remove harmful pathogens and other contaminants. The solids that remain after this treatment are then further processed into a safe and usable form.
The production of Milorganite involves several steps:
– The wastewater treatment process removes water and volatile substances from the biosolids, reducing their volume and creating a more stable product.
– The biosolids, now in a semi-solid state, are then subjected to high temperatures to kill any remaining pathogens, ensuring the final product is safe for use in gardening and agriculture.
– After heat treatment, the material is dried further and ground into a fine powder, which is the Milorganite fertilizer used by gardeners and farmers.
Composition of Milorganite
The composition of Milorganite fertilizer is primarily organic matter, with a significant portion being in the form of slow-release nitrogen, phosphorus, and iron. These nutrients are essential for plant growth and are released slowly as the plants need them, reducing the risk of over-fertilization and environmental pollution. While it’s true that Milorganite is derived from wastewater treatment byproducts, the extensive treatment and processing it undergoes ensures that the final product is free from harmful pathogens and contaminants.
The Human Waste Question
The concern that Milorganite is made from human waste stems from its origin as a byproduct of wastewater treatment. However, the treatment process is designed to remove and kill pathogens, making the final product safe for use. The process of creating Milorganite includes heating the biosolids to high temperatures, a step that is crucial for pathogen destruction. This means that by the time the biosolids are transformed into Milorganite fertilizer, they no longer contain harmful pathogens associated with human waste.
