2. Processing (canning, drying, freezing, and preparation of
juices, jams, and jellies) increases the shelf life of fruits and
vegetables. Processing steps include preparation of the raw
material (cleaning, trimming, and peeling followed by
cooking, canning, or freezing. Plant operation is often
seasonal
3. The fruit and vegetable industry typically generates large volumes of
effluents and solid waste. The effluents contain high organic loads,
cleansing and blanching agents, salt, and suspended solids such as fibers
and soil particles. They may also contain pesticide residues washed from
the raw materials. The main solid wastes are organic materials,
including discarded fruits and vegetables. Odor problems can occur with
poor management of solid wastes and effluents; when onions are
processed; and when ready-to-serve meals are prepared.
Waste Characteristics
4. Reductions in wastewater volumes of up to 95% have been reported through implementation
of good practices. Where possible, measures such as the following should be adopted:
Procure clean raw fruit and vegetables, thus reducing the concentration of dirt and organics
(including pesticides) in the effluent.
Use dry methods such as vibration or air jets to clean raw fruit and vegetables. Dry peeling
methods reduce the effluent volume (by up to 35%) and pollutant concentration (organic
load reduced by up to 25%).
Separate and recirculate process wastewaters.
Use countercurrent systems where washing is necessary.
Use steam instead of hot water to reduce the quantity of wastewater going for treatment
(taking into consideration, however, the tradeoff with increased use of energy).
Minimize the use of water for cleaning floors and machines.
Remove solid wastes without the use of water.
Reuse concentrated wastewaters and solid wastes for production of by-products.
Pollution Prevention and Control
5. Preliminary treatment of wastewaters should include screening (or sieving to
recover pulp) and grit removal, if necessary. This is followed by pH adjustment and
biological treatment of the organic load. The flows are frequently seasonal, and
robust treatment systems are preferred for onsite treatment. Pond systems are used
successfully to treat fruit and vegetable wastes, but odor nuisance, soil
deterioration, and groundwater pollution are to be avoided. The quality of the
effluent is normally suitable for discharge to municipal systems, although peak
hydraulic loads may cause a problem. Odor problems can be avoided by using gas
scrubbers or biofilters.

Ample processing industries present.
Agro Food Parks developed at Kota, Jodhpur, Sriganganagar and Alwar.
Although surplus commodity but supply is limited Haryana, Uttarakhand, Punjab and South India.
Limited amount exported to Oman, Sri lanka, Malasia.
Drying of onion and essence can be practiced at large so that wastage is less and it can be used
when the prices of onion is at its peak.
