PRODUCT WISE WASTE MINIMIZATION OPTIONSPRODUCT WISE WASTE MINIMIZATION OPTIONSProduct Waste Minimisation OptionsMonocrotophos In the manufacturing process of Monocrotophos, chlorination efficiency
can be improved by providing multiple entries of chlorine in the reactor.Process conditions are to be optimized to minimize formation ofdichlorides of Monocrotophos Aceto Acetamide (MMA), which are,resulting in formation of other products going in the waste. PurerTrimethyl Phosphite (TMP) is to be used to minimize input of impuritiescoming along with TMP leading to waste.Improving distillation to minimize EDC and degradation product inresidue.
Profenophos In the manufacturing process of Profenophos, efficiency of brominationneeds to be improved by adopting stagewise bromination and optimizingthe process parameters. This will minimize formation of other bromidesand impurities which form waste. Recovery of Trimethyl Ethyl AmineBromide (TMEABr) from aqueous layer will reduce the load on ETP andpresence of organic impurities in ETP sludge.Optimisee the process to minimize dibromochlorophenol andsubsequent organinc intermediates

Acephate In the manufacturing process of Acephate, lower overall efficiency of theprocess and lower recovery efficiencies for solvent are leading to waste.There is a scope to optimize process efficiency and improve solventrecovery system and thereby reduce the waste.
Chloropyrophos In chloropyrophos, manufacturing process, lower extraction efficiency isresulting in loss of Chlorpyriphos in the waste. Use of centrifugalextractors with optimized process conditions will improve extraction ofChlorpyriphos and thereby reduce the waste. Contd…
Ethion In the manufacturing process of Ethion, direct controlled addition ofP2S5 in alcohol and elimination of solvent may result in total eliminationof process waste.
Zinc/Aluminiumphosphide
In the manufacturing process of phosphides of zinc and aluminium partof the phosphorous is burnt for generating high temperature. This inturn results in generation of waste. Developing an electric arc furnacewill solve this problem. Dusting of the product also needs to beminimized.
Endosulfan In the manufacturing process of Endosulfan, recovery of Endosulfanneeds to be improved by improving centrifugation and thereby reducingEndosulfan in the waste
Cypermetharin In Cypermetharin manufacturing process, there is a scope to reduce thequantity of sodium cyanide used and thereby reduce the load ondetoxification and generation of detoxification sludge.
In Cypermetharin manufacturing process, there is a scope to reduce thequantity of sodium cyanide used and thereby reduce the load ondetoxification and generation of detoxification sludge.
Fenvalerate In the manufacturing process of Fenvalerate, better heat transfer andtemperature control will the loss of alkyl in alkyl distillation inFenvalerate. Use of acidic ion exchange resin can minimizerequirement of acid and thereby generation of waste.
Malathion andDimethoate
In the manufacturing process of Malathion and Dimethoate, minimizingwater content of methanol, P2S5 and equipment will minimizegeneration of phosphoric acid, which results in formation of waste.Drying of Malathion and Dimethoate at lower temperature, using highervacuum will reduce thermal degradation of the product.

RECOMMENDATIONSRECOMMENDATIONS
1. For hazardous waste management followinghierarchy should be followed:-a) Prevention – Waste generation can be prevented
using clean technology
b) Minimization – waste generation can be Minimizedby using good practices
c) Reuse;d) Recycling;e) Recovery, utilisation including co-processing;f) Safe disposal.

2. For chemical industry (pharma, pesticides, dyeand dye intermediates etc.) the wasteminimization as prescribed by CPCB should befollowed.
3. Utilization of waste for making new products aselaborated in earlier slides should be followedas far as possible.
4. After following waste minimization scheme thehigh COD waste to be segregated and high CVwaste should be co-processed in cement kiln.
5. The spent solvent / mix solvent generated bychemical industry should be co-processed incement kiln.

6. Setting of pre-processing plant to beencouraged either at cement plant site or atTSDF site.
7. The last option for hazardous wastemanagement may be disposal of waste inTSDF. However, the leachate quality w.r.t. CODand TDS should be regularly monitored.
8. The MEE / drier salt should be encouraged tobe reused. Last option for disposal of the samemay be in landfill after packing in HDPE bags.
9. Recycling of waste such as used lead batteries,aluminum, copper, zinc waste, waste oil, usedoil, etc. to be promoted. Financial incentives forrecycling and recovery of metals like lead, zinc,aluminum, may be given in order to savenatural resources and reduce green houseemission.

10. RDF from MSW to be used as partial fuel incement kiln. This may be included as a part ofCSR programme to manage the MSW disposalproblem.
11. Fly ash (ESP ash) should be used to produce flyash pozzolona cement.
12. Blast furnace slag from steel industry should begranulated and used for cement making.
13. Coke oven sludge / distillation residue / mixedwaste solvent, spent carbon etc. should be usedas partial fuel in cement kiln
14. Oily sludge from oil refinery / petrochemicalindustry should be used for co-processing incement plant
