    Acknowledgements

    Words often fail to express one's inner feeling of gratitude and indebtedness to ones

    benefactor but then it is only readily available medium through which one can express his

    sincere thanks to all those who are associated with the work.

    I would also like to thank Mr Sanjay Arora, Owner of Sanjay Textiles Pvt. Ltd., without

    whose support it would have been impossible to do this project. His deep insights and

    knowledge really helped me in understanding the roes and duties of industries in conserving

    our environment and lead a sustainable life.

    I sincerely thank Dr. K. L .Chawla, Faculty of Economics, FORE School Of Management

    who provided us this wonderful opportunity to enhance our learning in Legal Aspects of

    Business. I am grateful towards him for his cooperation and his knowledge enhancing inputs.

    I also extend my heartfelt gratitude for his enlightening classes that helped me develop a keen

    interest in the subject.

    Introduction

    Sanjay Dyers Pvt. Ltd. is a dyeing factory that was started by Mr Sanjay Arora, a textile

    engineer, as a small factory in 1987 in the area of Chandni Chowk in Delhi. The raw materialfor the dyeing process is cotton yarn. The factory has 17 workers and operates 6 days a week.

    There are six sections in this factory that can classify as below:

    1) Spinning and warping section is located on second floor of the building. There are two

    spinning machines and one warping machine.

    2) Sizing section - There is one sizing machine. Small volume of wastewater from this

    section is directly discharged to drainage channel beside the plant.

    3) Weaving section - there is seven weaving machines. This section has an automatic

    controller controls temperature and humidity. Small amount of water is used.

    4) Dyeing section - includes desizing, scouring, bleaching, dyeing and finishing processes.

    Dyeing process is reactive dyes that it is used for cotton cloth.

    5) Drying section - is located on second floor and is separated into two steps; first the dye

    cloth is dried in big one of dryer machine. After that is dried in small dryer, these are two

    machines.

    6) Sewing, inspecting and packaging section - there are four sewing machines.

    The most significant environmental problems from production processes in the factory are

    following:

    Wastewater: Large amounts of wastewater contain high SS, TDS, BOD, pH and color is

    discarded which leads to water pollution.

    Noise: Weaving machines make produce a lot of noise leading to noise pollution

    Dust: Cotton dust is dispersed in all of plant area leading to air pollution.

    Pollution caused during each step

    1. Spinning and Warping - Processing of fibres prior to and during spinning andweaving generates dust, lint etc. which degrades working environment in the industry.

    Dust may cause respiratory diseases in workers. A chronic lung disease, byssinosis is

    commonly observed among workers exposed to cotton, flax and hemp dust. Besides

    this, there are a number of process operations including spinning weaving that

    produce noise to the tune of 90 dB (A).

    2. Si i Thi st i l s di i of fabri i aqueous starch suspensions tostrengthen the fibres which aid them in withstanding allthe friction and stretching and

    straining of weaving. Dust particles released during this process cause air pollution.

    3. Weavi This is the process of making of fabric by interweaving two threads. Thisprocesses releases dust particles of fabric and also causes noise pollution.

    4. Dyei

    y Desi ing: To remove the substance applied to the yarns to imparttensile strengthin the si ing operation. There are two methods; acid desi ing and enzyme

    desizing. After the size has been solubilized, the fabric is rinsed clean in hot

    water.

    y Scouring: To remove the natural and acquired impurities from fibers and fabric.Scouring agents include detergents, soaps, alkalis, wetting agents, foamers, and

    lubricants.

    y Bleaching: Bleaching is used to remove the natural yellowish coloring of thecotton fiber and renders it white. The three bleaching agents most commonly used

    are sodium hypochlorite, hydrogen peroxide and sodium chlorite. The final rinse

    may contain an antichlor, sodium bisulfite or sulfuric acid, to remove residual

    chlorine from the fabric.

    y Mercerizing: Mercerizing is used to increase the water absorbency of cotton, toimpart brightness, to increase dye affinity, and tensile strength.

    y Dyeing: The dyeing process is carried out in an aqueous bath with pH variationsof 6 to 12. Dyes used by the textile industry are classified according to

    application, e.g. acid dyes, direct dyes, basic dyes, disperse dyes, mordent dyes,

    pre-metallised dyes, reactive dyes, sulphur dyes, vat dyes.

    y Finishing: A final size or resin is applied to impart a smooth appearance andstiffness. Special treatments such as heat proofing, etc. are also done something.

    The entire dyeing process involves water pollution and noise pollution.

    5. Drying Involves drying of fabric using oven treatment

    6. Cutting and sewing Involves cutting of fabric in the required shape and sewing it.

    7. Inspecting and Packaging Involves checking for imperfections in the fabric andthen packaging for delivery.

    the person who has established or taken steps to establish any industry, operation or process,

    or any treatment and disposal system or any extension or addition thereto, or using the outlet,

    Critical Analysis of Efficacy of Law

    Air Pollution

    y Prior consent has been taken from the State Board with all the formalities anddocuments in place.

    y Dynamic separators are used as control equipment which is in running conditionand properly filters the particulate matter.

    y Chimneys are used to throw the contaminated air out after filtering.

    Water Pollution -

    y Prior consent has been taken from the State Board for disposing the waste waterwith all the formalities and documents in place.

    y Minimum usage of sulphide dyes

    Noise Pollu

    tion

    y No heavy noise creating equipments used during night time.

    Recommendations

    1. New dyes should be used with better properties and low toxicity. Although these dyesmay be a bit expensive, but considering the potential long term savings made from

    efficient dye use and a lower effluent cost. It is worth every penny.

    y Development of fibre-reactive dyes for fibres like cellulosics, that has stablefixation rates without regard to variations in dyeing conditions.

    y Metal-free reactive dyes that has high fixation rates along with minimum saltconsumption.

  • 8/8/2019 Assignment on Legal Aspects of Business

    15/21

    12

    y The gradual withdrawal and newer replacement for azo-dyestuffs that are threat asa potential carcinogenic.

    2. The dyeing units are also not left behind when it comes to addressing the problem ofcontrolling pollution. Some of these effective steps are highlighted below.

    y Air conditioning system water is recycled.y Disseminating knowledge to workers for proper utilization of water and power

    consumption.

    y Installation of screens in drain lines that reduces the solid particles in effluents.y Proper implementation of a maintenance plan for steam traps.y Digital monitoring systems for use in boilers.

    3. General control measures

    y Height of chimneys: Chimneys height should not be less than 30 meters andrelease the pollutants not in the vicinity of living organism.

    y Gravitational & inertial separator: Better suited gravitational and inertial conceptsof collecting, filtering etc of the particulate matter. Eg. settling chambers, wet

    cyclones & multiple cyclones.

    y Filters: Woven or sintered metal beds of fibres, metal turning, fibrous mats &aggregate bed filter, paper filters and fabric filters are used for the filtration of

    particulate matter like dust, lint and fumes.
