Fly ash is mainly utilized in making of bricks, construction of dams, road embankments, in making buildings, etc., but its utilization in agriculture is only 1% (Fig. 21.1 ). Fig. 21.1. Fly ash utilization in different sectors (2017–2018) Full size image. Fly ash is an inorganic waste produced after combustion from thermal power plant every year.

For example, fly ash conversion to zeolite-carbon composites may reduce the environmental cost of depositing fly ash, which is currently approximately 80 EUR/tonne. Unfortunately, current rate of recycling of fly ash is still low in comparison to its' global production at the level of million tonnes per year (Fig. 1).

The residues from coal combustion entering the flue gas stream are known as fly ash (FA). An energy sector of India accounts for nearly 13 million ton's of FA generation per year. Fly ash production in year 2005–2006 in India was 112 million tons and is expected to reach about 170 million tons year −1 by the end of 2012 (MOEF 2007) (Table …

For control of aphids, spider mites, and walnut aphid, use 1½ to 2 pints of MALATHION 5 per 100 gallons of water. For control of European red mite, use 1¼ pints per 100 gallons of water. For control of pecan phylloxera, pecan budmoth, and pecan leaf casebearer, use 1¼ pints per 100 gallons of water. Apply when buds begin to develop.
