Preparation of ammonium bicarbonate from waste effluent of dyes/dyes intermediate industries containing ammonium carbonate

IPR Status & Details:

IN 301912

Application/Uses/Problem being addressed

The main uses of the product are: Nitrogenous fertilizer (India is still importing nitrogenous fertilizer), livening agent, blowing-agent for rubber foam products, ingredient for fire extinguisher, de-greasing of textiles, cooling baths, ceramic industry and light weight brick production, catalyst manufacture, smelling salt, pharmaceutical industry etc. It is used as a foaming agent in elaboration of plastics and rubber.

It is also used as a component in the manufacture of fungicides, and cleaning products

Salient Technical Features including Competing Features/ Impact

Cost effective and simple process to produce ammonium bicarbonate with purity greater than 99% that meets the specifications for various applications from the organic pigment effluent. The advantages are: Conservation of water, production of value-added product, elimination of polluting stream.

TRL Level & Scale of Development:- TRL 4 TRL Reference

Pilot scale

Business scope & opportunity (in terms of scale, cost, market etc.)

The ammonium bicarbonate industry is driven by the rising food industry, where it is employed as an active baking agent in the production of baked goods like biscuits, cookies, among others. Further, the growing population and urban development are strengthening the demand for food, which is likely to have a positive impact in the forecast period as well. In addition to this, the product is also finding extensive use in the end-use industries, such as rubber and leather industry, among others. The sustainable growth of these industries is predicted to aid the ammonium bicarbonate industry positively.

Environmental Considerations

Environmentally friendly and cost-effective process from the effluent generated in organic pigment industry

This effluent of pigment industry is either discharged in water bodies such as sea or sea creeks or used by magnesium carbonate manufacturers who dispose ammonium salt containing effluent resulting in death of birds and aquacultures. The process will be an important tool for generating wealth from the waste with simultaneously abating pollution problems to bring about benign environment.
