Recycling toxic waste for beneficial application
Recycling toxic waste for beneficial application
South African soils are known to have a relatively low natural carbon (organic) content. It is also a fact that through poor farming strategies, our agricultural soils have been depleted of organic material and natural nutrients. Plants growing in soil with insufficient organic material and nutrients are less healthy, produce poorer crops, and are less resistant to pests.

Waste Water Treatment Plants (WWTP) receive sewage wastewater from households, shopping centers, office complexes, industry, etc. This waste is treated, and potable water is returned to rivers or dams and the bio waste or sewage sludge, which has been removed from the water, is disposed of in many ways. Most of these disposal methods are environmentally unfriendly with many examples of toxic sewage sludge pollution.

The know-how and technology are available and mature to utilize waste organic material, such as sewage sludge, sterilize it and enrich it with essential plant nutrients. The resultant products contain organic material, primary nutrients as well as all the trace elements required for superior plant growth.

The uniqueness of this proposed process is that it produces a high-grade multifunctional fertilizer and at the same time it solves a major sewage pollution problem cost-effectively.

A high-grade multifunctional fertilizer is a product that contains:
A high-grade multifunctional fertilizer is a product that contains:
⦁ The macronutrients are Nitrogen (N), Phosphorus (P), and Potassium (K).
⦁ Micronutrients such as Zinc (Zn), Iron (Fe), Copper (Cu), Magnesium (Mg), Calcium (Ca), Silica (Si), and Manganese (Mn).
⦁ Organic material and other organic nutrients.

Most fertilizers available contain only macronutrients with some micronutrients added by chemical processing. Organic fertilizers that are currently available use composted animal and bio waste to which chemical fertilizers are added. These organic fertilizers are only available in limited quantities as animal and biowaste quantities are limited.
