Solid Waste Processing via Soil Biotechnology (SBT):
SBT harnesses the bioenergy in organic matter by integrating the elements of a productive soil ecosystem viz. Soil bacteria, select earthworm and plant species and mineral nutrients. Litter pests indicate over loaded process and warrant corrective measures. Biocarbon energy contained in the waste is tapped to unlock plant nutrients from minerals, fix atmospheric nitrogen and produce metabolites to be assimilated by plants and thus prevent wasteful dissipation of the carbon energy. Select aerobic bacteria and mineral additives prevent foul odor in the process. Two grades of product can be harvested from the process viz. Fertilizer grade and Culture grade depending on the end use application. The waste processing area is thus developed into a green belt or garden, which easily integrates into any existing landscape.

The end uses of the product include agriculture, horticulture, wasteland development and public sanitation.

Wastewater processing for Reuse via SBT:
In this technology organic waste water is processed in an ecosystem consisting of soil, bacterial culture and geophagus earthworm, mineral additives and select plants. Formulated natural additives are also included in the process in order to renovate the wastewater to the desired quality.

The process by design integrates with the natural bio-geochemical cycles of nature. The processed water can support fish life. Water quality up gradation for different end use applications can be achieved via suitable process design. SBT system consists of an impervious containment typically 1.0 – 1.5 m below ground and incorporates soil, formulated filter media, select species of earthworms and plants. Arrangement for external addition of formulated additive is provided in the design. Purification takes place by adsorption, filtration and biological reaction. The process operates in aerobic mode; thus eliminating possibility of foul odor.

The processed water can be reused in gardening, agriculture and support marine life.

Potential Applications :

* Waste water renovation for use in construction, soil application such as gardening.
* Polishing of industrial effluent treatment to meet discharge standard.
* Processing of organic solids of municipalities, food processing dairies, hospitals, waste from densely populated less privileged communities including excreta.
* Non chemical cleaning of swimming pools.
* Drinking water purification for small communities.

Advantages:

* Exceeds international environment norms.
* Costs effective compared to conventional technologies.
* 70% of capital costs
* 40% of operating costs.
* Produces Bio-mineral fertilizer and soil as by products.
* 10000 times more effective in bacterial removal.
* 100 times more effective in COD removal.
* Self sustaining revenue model.
