HOW SPENTWASH IS GENERATED

• Sulfur dioxide, chlorine, ammonium bisulfite or commercial FDA-approved biocides are sometimes used to disinfect cane juice.

• Milk of lime (a slurry of calcium hydroxide) and phosphoric acid is added to cane juice during the clarification step; however, lime is mostly removed by filtration during clarification.

• Several other chemicals are used in sugar manufacturing process at different stages. • Molasses are one of the final by-product of sugar manufacturing. • Fermentation followed by distillation is the most common naturally occurring biological process used to

manufacture ethanol. • Yeast strains are traditionally used to perform the alcoholic fermentation of diluted molasses. Other genetically

modified microorganisms or enzymes are also used sometimes in the process. • The pH of the fermentation broth may be lowered (pH = 4–5) using sulfuric acid to minimize the risk of bacterial

contamination. • In addition, antibiotics (e.g., penicillin) and bactericides (e.g., chlorine dioxide) are potentially added to control

bacteria present in the molasses feedstock. • Most of the above steps & process additives are involved in generation of spent wash from cane molasses. S

COMMON INCINERATION FACILITIES

• As the common incineration systems will be handling wastes having varying heat value, and while ensuring TOC and LOI requirements in the ash/slag, there are possibilities for sudden rise of temperatures in the kiln. Therefore, the facilities may like to have thermal refractory bricks and insulation capable of withstanding a minimum temperature of 1,300°C (typically, corundum / chromium bricks).

COMBUSTION CHAMBERS (Rotary Kiln and Secondary Combustion Chamber)

Rotary Kiln

• In the rotary kiln, the temperature shall be maintained at 800+°C in order to ensure complete burning of solid waste. Controlled flow of air shall be maintained for complete volatilization of solid waste.

Secondary Combustion Chamber

• Minimum temperature requirement in the secondary combustion chamber is 1100° C.

ANY EFFLUENT (SPENT WASH IN THIS CASE) CONTAINING HALOGEN COMPOUNDS & COPPER TRACES,

IF INCINERATED, PRODUCES DIOXIN. AND DIOXINS ARE PROVEN CANCEROUS COMPOUNDS.

• smokestacks of the incinerator. Dioxin particles are then carried by the wind until they drop onto land or

• water. We now know that dioxin can travel thousands of miles. Grazing animals and fish ingest the dioxin, but

• they cannot break it down, so it then travels up the food chain. Ninety percent of human exposure to dioxin

• occurs through our diets of meat, dairy products, eggs and fish.

• Dioxin builds up in fatty tissue. Because of the high fat content of breast milk, nursing infants are exposed to

• about 50 times the adult dose and may receive more than 10 percent of their total lifetime exposure during the

• nursing period, a time when they are most vulnerable to the toxic effects of dioxin.

• Every person has some amount of dioxin in their body. This is because dioxin, like DDT, does not readily break

• down in the environment. It also accumulates in the body. Continual low-level exposure leads to a "build up" in

• tissues.

WHAT IS DIOXIN• Dioxin is the common name for a class of 75+

chemicals. • Dioxins have no commercial use. • It is a toxic waste product formed when waste

containing chlorine is burned. • Dioxin particles emitted with smokestack of

incinerator does not readily break down in the environment and are carried by the wind.

• Grazing animals and fish ingesting dioxin, cannot break it down, so it travels up the food chain.

• Continual low-level exposure may leads to a "build up" in tissues resulting into several health problems.

EFFECT OF DIOXINE ON HUMAN HEALTH

CANCER: DIOXIN IS A PROVEN HUMAN CARCINOGEN ( INTERNATIONAL AGENCY FOR RESEARCH ON CANCER (IARC). DIOXIN CAUSES LIVER, LUNG, STOMACH, SOFT AND CONNECTIVE TISSUE CANCERS AS WELL AS NON-HODGKINS’S LYMPHOMA.

IMMUNE SYSTEM EFFECTS: LOW EXPOSURES TO DIOXIN RESULT IN INCREASED SUSCEPTIBILITY TO BACTERIAL, VIRAL AND PARASITIC DISEASES.

REPRODUCTIVE AND DEVELOPMENT EFFECTS : DIOXIN EXPOSURE CAUSES HUMAN STUDIES REPORT LOWERED TESTOSTERONE LEVELS IN HUMAN AND BIRTH DEFECTS IN THEIR CHILDREN. NURSING HUMAN INFANTS EXPOSED TO HIGH DIOXIN CONCENTRATIONS HAD SIGNIFICANTLY LOWER LEVELS OF THE THYROID HORMONE NECESSARY FOR DEVELOPMENT OF THE BRAIN.

HORMONE DISRUPTION: DIOXIN BEHAVES LIKE A HORMONE BY ATTACHING TO A RECEPTOR AND ALTERING THE GENETIC ACTIVITY IN CELLS. SINCE HUMAN HORMONES CAN EXERT EFFECTS AT LEVELS OF PARTS PER TRILLION, SMALL AMOUNTS OF DIOXIN COULD CAUSE A CHAIN REACTION IN THE BODY.

N YOU NEED TO ENLARGE ABSTRACT OF THIS WORK PASTED BELOW, WHICH SAYS CERTAIN VERY IMPORTANT THINGS OTHERWISE IGNORED WHILE ISSUEING DIRECTIVES FOR INCINERATION TO DISTILLERIES.

ADDITIONALLY, DIRECTIVE 2000/76/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 4 December 2000 on the incineration of waste from Official Journal of the European Communities need to be studied before such directives.

There has been great concern about dioxins-polychlorinated dibenzo dioxins (PCDDs), polychlorinated dibenzo furans (PCDFs), and polychlorinated biphenyls (PCBs)-causing contamination in the environment because the adverse effects of these chemicals on human health have been known for

many years. Possible dioxin-contamination has received much attention recently not only by environmental scientists but also by the public, because dioxins are known to be formed during the combustion of industrial and domestic wastes and to escape into the environment via exhaust gases from

incinerators. Consequently, there is a pressing need to investigate the formation mechanisms or reaction pathways of these chlorinated chemicals to be able to devise ways to reduce their environmental contamination. A well-controlled small-scale incinerator was used for the experiments in the core

references of this review. These articles report the investigation of dioxin formation from the combustion of various waste-simulated samples, including different kinds of paper, various kinds of wood, fallen leaves, food samples, polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC),

polyvinylidene chloride, polyethylene tetraphthalate (PET), and various kinds of plastic products. These samples were also incinerated with inorganic chlorides (NaCl, KCl, CuCI2, MgCl2, MnCl2, FeCl2, CoCl2, fly ash, and seawater) or organic chlorides (PVC, chlordane, and pentachlorophenol) to

investigate the role of chlorine content and/or the presence of different metals in dioxin formation. Some samples, such as newspapers, were burned after they were impregnated with NaCl or PVC, as well as being cocombusted with chlorides. The roles of incineration conditions, including chamber

temperatures, O2 concentrations, and CO concentrations, in dioxin formation were also investigated. Dioxins (PCDDs, PCDFs, and coplanar-PCBs) formed in the exhaust gases from a controlled small-scale incinerator, where experimental waste samples were burned, were analyzed by gas

chromatography/mass spectrometry. Formation of total PCDFs was much higher than that of PCDDs in all samples. The total PCDFs comprised 70%-90% of the total dioxin formed. The amount of total PCDFs formed ranged from 0.78 ng/g (newspaper) to 8,490ng/g (PVC burned in high CO

concentration). The amount of total PCDDs formed ranged from 0.02ng/g (newspaper) to 430ng/g (PVC). Coplanar PCBs were found at the lowest level of the dioxins formed. Their formation levels ranged from 0ng/g (newspaper) to 77.6ng/g (PVC). It is obvious that the samples with either inorganic or

organic chlorides produced much more dioxins than the sample without chlorides when incinerated under similar conditions. It is not clear how inorganic and organic chloride contribute differently to dioxin formation. Among the metals examined, copper seems to have higher activity toward dioxin

formation than other metals. It acted not only as a catalyst but also as a transmitter of heterogeneous chlorine. The toxicity equivalence quantity (TEQ) values generally correlated with the amount of chlorine content in the samples and the amount of dioxin formed in exhaust gases from an incinerator.

When the same sample was incinerated at different temperatures, however, the sample burned at low temperature yielded a higher TEQ value than did the sample burned at high temperature. The samples that did not contain chlorine or were not combusted with chlorides exhibited low TEQ values. In

contrast, samples with high chlorine content, such as PVC (51.3%), gave high TEQ values. Combustion temperatures may play an important role in dioxin formation in exhaust gases from the incineration of waste materials. However, no significant relationship between dioxin formation and chamber

temperatures was reported in the core articles. However, It is obvious that dioxin formation occurred at temperatures above 450'C and was reduced significantly at temperatures above 850 degrees C. The reaction occurring in an incinerator is extremely complex, and there are many factors in addition

to combustion temperature influencing dioxin formation. Even though it is possible to hypothesize reasonable formation mechanisms of dioxins produced in exhaust gases according to the results obtained from experiments in classical chemistry, the reactions involved in an incinerator are extremely

complex and heterogeneous. More detailed investigation of the many individual factors influencing dioxin formation is needed to find ways to reduce their formation in individual and municipal incinerators.

EUROPEAN COMMISSIONS COMMENT ON INCINERATION OF HALOGENOUS SUBSTRATES

Definitions• For the purposes of this Directive:• (1) ‘waste’ means any solid or liquid waste as defined in Article

1(a) of Directive 75/442/EEC;• (2) ‘hazardous waste’ means any solid or liquid waste as defined

in Article 1(4) of Council Directive 91/689/EEC of 12 December 1991 on hazardous waste (1).

• (3) ‘mixed waste’ means waste from households as well as commercial, industrial and institutional waste, which because of its nature and composition is similar to waste from households, but excluding fractions indicated in the Annex to Decision 94/3/EC (4) under heading 20 01 that are collected separately at source and excluding the other wastes indicated under heading 20 02 of that Annex;

• (4) ‘incineration plant’ means any stationary or mobile technical unit and equipment dedicated to the thermal treatment of wastes with or without recovery of the combustion heat generated. This includes the incineration by oxidation of waste as well as other thermal treatment processes such as pyrolysis, gasification or plasma processes in so far as the substances resulting from the treatment are subsequently incinerated.

This definition covers the site and the entire incineration plant including all incineration lines, waste reception, storage, on site pretreatment facilities, waste- fuel and air supply systems, boiler, facilities for the treatment of exhaust gases, on- site facilities for treatment or storage of residues and waste water, stack, devices and systems for controlling incineration operations, recording and monitoring incineration conditions;• (5) ‘co-incineration plant’ means any stationary or mobile plant

whose main purpose is the generation of energy or production of material products and:

— which uses wastes as a regular or additional fuel; or — in which waste is thermally treated for the purpose of disposal.

THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty establishing the European Community, and in particular Article 175(1) thereof,

(17) Member States should take into account Council Directive 1999/30/EC of 22 April 1999 relating to limit values for sulfur dioxide, nitrogen dioxide and oxides of nitrogen, particulate matter and lead in ambient air (4) when implementing this Directive.

(18) The incineration of hazardous waste with a content of more than 1 % of halogenated organic substances, expressed as chlorine, has to comply with certain operational conditions in order to destroy as many organic pollutants such as dioxins as possible.

(19) The incineration of waste which contains chlorine generates flue gas residues. Such residues should be managed in a way that minimizes their amount and harmfulness.

(27) The co-incineration of waste in plants not primarily intended to incinerate waste should not be allowed to cause higher emissions of polluting substances in that part of the exhaust gas volume resulting from such co-incineration than those permitted for dedicated incineration plants and should therefore be subject to appropriate limitations.

(28) High-standard measurement techniques are required to monitor emissions to ensure compliance with the emission limit values for the pollutants.

N • As per Shibamoto T1, Yasuhara A, & Katami T• The reaction occurring in an incinerator is extremely complex.

• Inorganic and organic chloride contribute differently to dioxin formation. Among the metals examined, copper seems to have higher activity toward dioxin formation than other metals. It acts not only as a catalyst but also as a transmitter of heterogeneous chlorine.

• Combustion temperatures may play an important role in dioxin formation in exhaust gases from the incineration of waste materials. Other key players in dioxin formation could be O2 concentrations, and CO concentrations.

FOR INCINERATION OR CO-PROCESSING :• MAXIMUM PCDD/F FORMATION OCCURS AT 300-400 °C, LITTLE CAN BE DETECTED BELOW 250

OR ABOVE 500 °C.• BOILER NEED TO BE SUITABLY OF HIGH TEMPERATURE IN CASE CHLORINE IS AVAILABLE IN THE

FUEL MEANT FOR INCINERATION.• BESIDES RESIDENCE TIME SHOULD BE 4 – 5 SECONDS IN AN OXYGEN–RICH ATMOSPHERE.• MOST OF THE INCINERATION BOILERS OFFERED TO OR INSTALLED IN INDIAN DISTILLERY DOES

NOT MEETS THE TEMPERATURE CRITERIA TO REDUCE DIOXINE FORMATION.
