Industrial water use has triggered off a host of problems
In developed and developing countries alike, competition among water users is increasing. Tensions are particularly high in water-scarce areas where domestic, agricultural and industrial water needs are pitted against each other. In developing countries like India, where every segment of the economy is growing rapidly, the conflict will become unmanageable if not addressed now. Even today most big cities in India are getting piped water from far-off places. This is putting tremendous
pressure on the local population whose water is being snatched to feed urban and industrial growth. Read More

TERI : Technology foresight for Asia: environmentally sound technological options (Source)
Sponsor(s) : Cornig Inc.
Completion date : April 2006
Technological development and the growth of a country are intertwined with each other. Technology assists in achieving the varied milestones set by a nation. Many technological innovations are expected to emerge from Asia in the coming decades as the region is progressing rapidly. Moving away from its erstwhile agrarian economy, the region is expanding its industrial base and services sector.

TERI : Developing PDD (project design document) under CDM for fuel switching, industrial co-generation and surplus power generation (Source)
Sponsor(s) : Indian Acrylics Limited
Completion date : October 2005
Till March 2000, the requirement of M/s Indian Acrylics Ltd, Sangarur (Punjab), of process steam was met by three on-site oil-fired process steam boilers. The oil-fired boilers have been converted subsequently to rice-husk-fired fluidized bed boilers, in phases during 2001?02. The specifications of the oil-fired boilers being used earlier and the converted boilers were given. Each of the boilers is capable of producing 16 tonnes of steam per hour at 18.75 kg/cm2 (kilogram per square metre) pressure and 350 C at the rated capacity. A part of the process steam is required at 425 C, which is being produced by passing the saturated steam, from the main header, through a separate oil-fired steam superheater (this was being done before the fuel was switched to rice husk). As replacement of existing steam pressure reduction and de-superheating system, one back pressure turbine-generator set of 1.025 MW (megawatt) capacity was also commissioned in July 2003 to run the process steam boilers in co-generation mode.

TERI : Safeguarding of oil pipelines by controlling microbial induced corrosion through biotechnological approach (Source)
Sponsor(s): Oil and Natural Gas Corporation Limited
Start Date: March 2006
One of the major economical losses faced by the oil corporates are due to corrosion in pipelines. The internal corrosion in pipelines is basically caused by the MIC (microbial-induced corrosion). It negatively impacts the integrity, safety, and reliability of oil pipeline operations throughout the world. This microbial-induced 'tuberculosis of the pipelines' as termed by the oil companies, is of prime concern regarding the huge economic loss. One of the major drawbacks associated with this problem is that the damage can be local and extremely hard to detect. With collaborative effort of Corporate Health Safety and Environment, Oil and Natural Gas Corporation Ltd, Mumbai, the project aims to develop rapid detection methods to address the problem of corrosion-causing microbes in the oil pipelines. Further, design of biocides for control of the MIC-causing microbes will also be attempted.

Atul : Change Of Technology - Replacement of Mercury by Membrane Cells

The Mercury Cells technology for manufacture of Caustic Soda leads to Mercury pollution of water brine sludge as well as the ambient air in the Cell House. To reduce this pollution and to save the energy, half the number of old Mercury Cells were replaced by Membrane Cells, which do not require the use of mercury and complete switching over to Membrane from Mercury Cell is under active consideration.

Atul : Use Of Reverse Osmosis System

Conventional method for separation of impurities from highly water-soluble dyes involved salting out and filtration. In spite of salting, fairly large percentage of dye (~ 5-10%) remained in the filtrate which was sent to the ETP. Now, we have installed and successfully commissioned 5 Reverse Osmosis (RO) units in our Colors Division to purify the water soluble dye by separation of low molecular weight water soluble impurities through membranes of selected pore size. Since the dye has a very high molecular weight, its molecules do not pass through the membrane. During the purification process, some amount of water also gets removed to concentrate the dye. The concentrated and purified (almost salt free) dye is taken directly for spray drying. Thus, the generation of effluent, containing higher percentage of dye and the use of salt giving additional TDS, is avoided.

Atul : Lime Stone Injection in Fluidised Bed Boiler

During burning of coal and lignite, some amount of SO2 is generated. To control this emission, we have started charging lime stone granules along with crushed coal. This ensures that the FBC Boiler Stack has SO2 content always within limits. Injected limestone is able to effectively scavenge the low concentration of SO2 because of excellent mixing available in Fluidized bed.

Atul : Catalystic Incineration and Heat Recovery (Formaldehyde Plant)

Formaldehyde is manufactured by partial catalytic oxidation of Methanol. After absorption of formaldehyde in water, a catalytic incineration system has been provided for the complete oxidation of vent gases including residual formaldehyde before release in the atmosphere. Platinum based catalyst is used for this purpose. When the vent gas enters the catalytic converter, it gets heated to 300oC. At this temperature in the presence of a catalyst, toxic gases are oxidized and the heat released is recovered in the form of steam.

Atul : Minimization of Emissions: DCDA system for H2SO4 plant

We have adopted Double Contact Double Absorption (DCDA) system for manufacture of Sulfuric acid on both of our plants apart from alkali scrubber system. This has ensured that the SO2 emissions are well below the recent prescribed limit.

Atul : Vapour Absorption Systems and Ammonia Compressors

For refrigeration system, earlier Chlorofluoro carbons (CFCs) were used. It is well known that CFCs causes depletion of the Ozone layer. Therefore in a phased manner, we have switched over to over to Vapor Absorption refrigeration system.

Atul : Sustainable Development

Atul Limited has been proactively adopting and promoting business practices that are eco-friendly apart from integrating “Sustainability” into work ethos since inception. It is evident from the fact that we are operating our facilities successfully in harmony with the community since 1947 without any adverse impact on the environment. The nature of our activities makes an efficient utilization of resources, environmental protection, operational safety and employee health.

Atul : Adoption Of Clean Development Mechanism

We have not limited ourselves to the statutory requirements but have gone beyond compliance. In the process, we have successfully installed a plant for brick manufacturing, having capacity of 100000 bricks per day. As a result we are now in a position to consume entire fly ash being generated from our captive power plant and gypsum sludge at Atul site.

Elimination of CFCs
In December 1995, J&J Ltd. became the first company in India to successfully eliminate CFCs from its manufacturing operations. This required the company to modify the sterilization processes at its Ethicon suture finishing plant at Aurangabad.

Thereafter, J&J Ltd. eliminated CFCs from all air conditioning and refrigeration equipment whose capacity was greater than 5 tons. This necessitated retrofitting three air conditioning/chilling plants of 180 ton capacity for conversion from CFC to HCFC 22 (R123) gas at a cost of USD 76000/- at the Ethicon suture finishing plant at Aurangabad.

The company's dedication to protecting the environment is evident, given that the Montreal Protocol does not require third world countries to phase out CFCs until the year 2010.

Northern Coalfields Limited :

Technical and biological reclamation of external OB dump in open case mines -
A case study of OB dump No. 2 of Jayant OCP
Summary of Case Study
Northern Coalfields Limited is subsidiary of Coal India Limited located in Sidhi district of Madhya Pradesh. Overburden dump consisting of soil and stones formed outside the open caste mine alter the surface topography, thus, making it prone to landslides if there are unstable slopes. The case study, funded by the World Bank involves various steps undertaken for technical and biological reclamation of OB dump No. 2 near Madwani reservoir.

Technical reclamation, i.e., construction of OB dumps with safe and stable slopes, has been adopted by preparing benches, including compacting, dressing, sealing of fissures, gullies and cracks, etc. The plan also involved constructing gabion retaining walls made of GI wires net cages filled with stone boulders and anchored with bamboo/ wooden ballies to provide vertical support to the bottom of slope. Drains on tip surface, periphery and along benches, thermally bonded non-woven geo-textiles wrapped under drain system, slit perforated PVC pipes laid in middle of the trench were other measures used to protect the slope surface against rain-cuts and seepage in rainy season.

Biological reclamation, i.e., operation and maintenance of OB dumps by vegetation has been facilitated through saplings planted at each bench as well as top of dump protecting against animals, pests, weather, etc. There are further provisions of jute mesh for facilitating grass growth, good soil mixed with manure and irrigation facilities for growth of grass for anchorage and control of soil erosion and dust emission. With the completion of technical and biological reclamation in Jan 2002, the total cost for the same was Rs. 2.19 Lacs for a slope surface area of 44,500 sqm. In addition to these, there is extensive afforestation program in and around mined area, which resulted in increase in forest cover from 40% to 80%.

Mecpro Heavy Engineering Limited:

Transforming edible oil refining into eco-friendly & efficient process
Summary of Case Study
MECPRO, with its refinery plant in Chattisgarh at Ganpati Solvex Pvt. Ltd., manufactures refined oils, gums, wax, and stearine. The case study focuses on introduction of the additional equipment/system in the existing Vegetable Oil Refining Plants, which helps eliminate Single Bleaching System besides using conventional Deodorisation System. In addition to land degradation concerns in disposal of bleaching earth, the existing deodorisation system also has environmental issues, like high steam consumption, low heat transfer co-efficient & deterioration in oil cum deodorisation technology.

The crude vegetable oil obtained by expression or Solvent Extraction from oil bearing materials contains a lot of unwanted components. Among these components most common are Free Fatty Acid content, phosphatides, colouring pigments, odoriferous material alongwith moisture and suspended solids. Most of these impurities are harmful for human consumption and hence need removal from the oil.

We have designed & developed process technologies for efficient twin bleaching system which reduces the bleaching earth consumption by 30%.

(I) TWIN BLEACHING TECHNOLOGY
In the existing process neutral oil is taken from intermediate tank and heated to raise temperature between 80oC - 100oC. Thereafter, the oil is transferred to bleacher where bleaching earth is added and then the bleached oil is pumped to filter from where the same is sent to final tank in such case 20 to 30% bleaching earth is consumed for removing the volatile material means inactivation's of 40% bleaching earth.

However, in our improved and modified twin bleaching system, initial four steps will be similar but after filtration, spend bleaching earth in the close loop pumped to 1st Bleacher where all volatile material will be removed, oil shall go to 2nd bleacher, where the fresh bleaching earth would be added and then the final bleached oil will be transferred to final oil tank. By adopting this modified process, the consumption of bleaching earth can be reduced by atleast 40%, resulting in significant cost saving.

(II) DEACIDIFICAITON CUM DEODORISATION TECHNOLOGY
The introduction of new technology will allow an alternative approach to the deodorization of oils. The major improvements in deodorization shall be in the areas of economy, quality, flexibility and ecology.

Refining of oils by conventional deodorization is generally made at 3mbar or even less and a stripping steam consumption of at least 20kg/ton of processed oil for deodorisation and 30 Kg for De-acidification. Application of counter current, thin film, new technology allows the stripping steam consumption to be reduced to one third and is accompanied by a dramatic reduction in operating costs with reduction of open steam sparging in turn the steam consumption in booster ejector also reduces

The efficient stripping process also involves a shorter residence time of the oil at elevated temperatures. As a consequence, there will be improvements in the organoleptic properties and quality parameters of the refined oil including low free fatty acid, colour reduction, bland flavour and taste, high levels of tocopherols and extended shelf life

The deacidification cum deodorization technology involves integrated pollution control and is associated with energy saving through high heat recovery and low sparging steam consumption. It is environmentally friendly and embraces the concept of a low emission deodorizer. There are certain disadvantages in the existing processes like in stripping, there is high steam consumption, low heat transfer coefficient, deterioration in oil quality etc.

However, by adopting thin film evaporation process, there would be less steam consumption and shall be highly mechanised and there will be less retention time required for deodorization, moreover, the limitation of stripping of FFA of less than 2% will also be eliminated. Presently, 2% of steam is consumed in deodorization process and 3 to 4% sparging steam is consumed in deacidification process. By introducing new system with bubble cap and structural column with seal less magnetic pump, the deacidification will be done with 1.5% steam consumption as compared to 3 to 4%.

Cost Benefit From Twin Bleaching System for a 100 TPD Edible Oil Refining Unit
Bleaching earth consumption = 70 Kg/MT
Saving due to twin bleaching 40% = 28 Kg/MT
Cost on bleaching earth (Average) = Rs. 25
Savings per day = 28 x 25 x 100 = Rs. 70,000
Savings per year = 70,000 x 300 = Rs. 2,10,00,000
Total oil processed in the country = 8000000 Tons
Total savings for the nation = 8000000 x 700 = Rs. 560 Crores

Cost Benefit from deacidification cum deodorisation system
Total heat energy required for Deacidification of 1 MT oil = 115000 KCAL
Heat recovered through economization = 57500 KCAL (50%)
Calorific value of LSD = 11000 KCAL/Ltrs.
LSD saved per MT of oil = 6 Ltrs.
Total oil processed = 8000000 MT
Total LSD saved = 48000000 Ltrs.
Cost of LSD = Rs. 26/Ltr.
Net savings for the nation = Rs. 124.8 crores

The majority of the nutritional components present in vegetable oils are being destroyed or removed during traditional alkali refining. Chemical refining of vegetable oil generally results in losses considerably higher. The reasons for the higher losses are attributed to the presence of larger amounts of free fatty acids and non-oily constituents. Refining losses can be considerably reduced using physical refining. The important prerequisite for successful physical refining is to keep the phosphorus content in the oil <10 ppm. The presence of phosphorus-containing components cause color fixation in the final oil during its exposure to the higher temperatures of physical refining. Water degumming is the simplest method for removing phospholipids (lecithin) from vegetable oils. However, only hydratable phospholipids can be removed during water degumming leaving 80 to 200 ppm of phosphorus in the oil, depending upon the type and the quality of the crude oil due to the presence of non-hydratable phospholipids. Presently, many refineries are pretreating vegetable oil with phosphoric acid or an organic acid (such as citric) for removing non-hydratable phospholipids. However, these methods failed to reduce the phosphorus content to <5 ppm and no method is known which can be reduce phosphorus level upto 5 ppm in industrial scale operations.

Enzymatic process is the answer for the entire problem as it catalyzes the conversion of non-hydratable phospholipids into water-soluble lyso-phospholipids, which are then removed by centrifugation, yielding degummed oil low in phosphorus. We have been able to upscale the lab scale technology developed by Indian Institute of Chemical Technology (IICT), Hyderabad to commercial scale successfully which has been implemented in several units across the country in association with IICT, a national laboratory of CSIR. An efficient enzymatic degumming technology for vegetable oil with commercially available enzyme, ensures a residual phosphorus level of 0 to 5 ppm after bleaching and dewaxing. This oil, if refined in a well-maintained physical refining unit, will produce good quality edible oil.

Advantages of Enzymatic Degumming process:
i. The enzymatic degumming process is very simple in operation. It can be adapted to the existing refineries with minor modifications in the pretreatment process. Adoption of this technology should give a big boost to proper utilization of this commodity and reduce the gap upto some extent in edible oil supply in the country.

ii. By adopting enzymatic degumming technology one can produce gums and waxes separately. Hence lecithin and lysolecithin from gums; and bleached wax and triacontanol from crude wax can be easily obtained.

iii. The oil loss during enzymatic degumming process is lower than in the conventional phosphoric acid degumming. The yield of the gums in enzymatic degumming is about 1.5% against 2-4% in the conventional degumming. The oil content of the enzymatic degumming gums is only 30-35% compared to 50-60% in the conventional gums. Thus there is a saving of about 0.6 to 1.4% of oil during the enzymatic degumming of the vegetable oil.

iv. The enzymatic degumming process does not alter the fatty acid composition of the vegetable oil.

v. The oryzanol present in crude rice bran oil remains almost intact during the enzymatic degumming.

vi. The enzymatic degumming is an eco-friendly process, as it does not generate effluent water. Effluent water is generated in the water wash step after conventional phosphoric acid degumming, whereas, water wash is not necessary after enzymatic degumming. Thus the possible oil loss in water washing step is also avoided in the process.

Asian Paints
Asian Paints approaches the environment issue from the perspective of waste minimisation and conservation of resources. Thus, the continued attempt is to reuse, recycle and eliminate waste, which results in less and less waste being generated. Accordingly material losses in manufacturing have been reduced substantially over the last few years. Further, the company's four paint plants and the two chemical plants in India have the ISO 14001 certification for environment management standards.
In 2002-03, Asian Paints instituted its own safety standards across all plants in India, which is based on the standards prescribed by the British Safety Council (BSC). This year, the four paint plants in India merited a Five-Star rating by the BSC. More significantly, three of our plants - Bhandup, Ankleshwar and Patancheru - were awarded the BSC's much sought after "Sword of Honour", which is considered as the pinnacle of achievement in safety across the world. The Sword of Honour is given to only 40 plants in the world each year and is designed to reward the best practices in this field. To have three of the company' s paint plants ranked among the top 40 in the first year of audit emphasises our steadfast commitment to safety.

Further due to various initiatives undertaken by the company at all its manufacturing facilities, Asian Paints was the recipient of the prestigious 'Golden Peacock National Quality award' for 2003. This is the most coveted quality award in the country.All our paint plants have achieved 'zero industrial discharge' capability. This has been achieved by the installation of upgraded effluent treatment facilities and installation of reverse osmosis plants in conjunction with appropriate recycling & reuse schemes. Our emulsion manufacturing facility has also achieved 'zero waste' status.

We have adapted the principles of "green productivity". Some of our innovative schemes, which enhance green productivity are

• Colour World dealer tinting system - allows for greater choice at the customer end thus reducing the number of shades produced in the factories. This has resulted in larger batch sizes and lesser number of changeovers leading to effluent reduction.
• Upgradation of material handling and storage facilities - such as the new bulk storage facility for monomers to reduce material losses and eliminate effluent generation arising out of barrel cleaning.
• Upgradation of process technology- has resulted in increased yield and therefore lesser pollution. For instance, the improved filtration process has resulted in higher filtration rates and lower losses.
• Use of natural gas as fuel - instead of furnace oil or diesel has not only improved fuel efficiency but also reduced sulphur dioxide emissions by 77%.
• Solvent recovery plants - set up with an investment of Rs.1.8 million, these plants have resulted in almost zero solvent disposal and have already yielded a direct benefit of Rs.10.4 million.
• Improved incinerating systems - have resulted in over 72 % reduction in waste after incineration. The remaining waste is also being re-used. For instance, we have eliminated the need for disposal of incinerator ash by manufacturing bricks. These bricks are used for internal construction purposes.
• Reverse osmosis - helps us re-use treated effluents in our cooling towers. This has reduced fresh water consumption by 50 kilolitres per day.
• Rainwater harvesting - scheme developed by us has become the benchmark for industries. Rainwater harvesting has resulted in around 14.5 million litres being harvested in 2003-04 and used at our plants.

As a result of implementing various water recycling, reuse and conservation measures in our plants, our average water consumption has reduced by 45 % inspite of production volumes of water based products doubling in the last five years. Asian Paints is committed to operate its plants and facilities in a manner to ensure continual improvement towards achieving 'CLEAN ENVIRONMENT'.
