Sustainability Drive : Mr. Subhasis Basu, Sr.General Manager, RSWM (LNJ Denim Unit)
"Sustainability is nowadays a way of life which creates a vibrant economy and a high quality of life while respecting the need to sustain natural resources and protect the environment based on the principle that future generation should live in a world that the present generation has enjoyed, but not diminished”.
The basic principles of Sustainable business are 3 Ps
i) Profit i.e. Economic
ii) People i.e. Social
iii) Planet i.e. Environment.
The purpose of the Sustainability drive is
i) Proper management of Sustainable aspects i.e. environment, social and economic.
ii) To find a coherent and long-lasting balance between these three aspects
iii) Respect the environment
iv) Prevention of exhaustion of natural resources.
v) To improve quality of life in both internal and external surroundings.
vi) Promotion and extensive use of Renewable energy sources i.e. Solar, Wind.
Activities under Sustainability can be in various forms as below.
i) Energy management which involves reduction of air, steam, and power consumption, use of energy-efficient latest technology, and introduction of renewable energy sources.
ii) Water management which necessarily means reducing, reusing, and recycling. An effluent treatment plant (ETP) is one of the major steps towards water management. And having ZLD (zero liquid discharge) facility in a plant fulfills this requirement.
iii) Chemical management which involves the use of RSL and MRSL-compliant chemical, registration on the Clean Chain portal, screened chemistry, proper segregation of hazardous and non-hazardous chemicals in the working area and storage area as well, and proper training to all concerned.
iv) Occupational Health and Safety compliances i.e. management system, emergency preparedness & fire safety, First aid, Aisles and Exits, Ventilation, and temperature, lighting, Personal protective equipment (PPE), Structural, mechanical and electrical integrity, Sanitation and Hygiene, Toilets, drinking water, kitchens.
v) Social accountability compliances i.e. working hours, overtime hours, different policies (anti-discrimination, sexual harassment, recruitment), no child labour, no forced labour, freedom of association & collective bargaining, non-discrimination, harassment & disciplinary practices, minimum wages, dormitories (If applicable)
vi) Waste management (reduce, reuse, and recycle) i.e. solid waste, e-waste
vii) Set up of different plants as below:
a. Effluent treatment plant (ETP) fitted with RO and MEE with a purpose of reduction in water consumption
b. Sewage treatment plant
c. Caustic recovery plant
d. Indigo recovery plant (for the Denim industry)
e. Sludge recovery plant
f. Green Building concept
g.Plantation in plant and surrounding areas.
h. Environmental protection measures
i. Awareness among all stakeholders via training and visual poster
j. Corporate Social Responsibility (CSR) activities
k.Customer satisfaction i.e. customer feedback form
l. Employee satisfaction i.e. employee satisfaction form, attrition ratio.
m. Innovation, development, and manufacturing of products with recycled materials, Post-consumer waste (PCW), and Pre Industrial waste (PIW).
n.Formation of special purpose cells as ESG (Environmental, Social, and Governance) which will look after exclusively these aspects.
There are several measures that can improve the Sustainability score of a factory.
i) Timely leak detention, preventive maintenance, and improved cleaning.
ii) Reuse of non-contact cooling water.
iii) It is high in quality and temperature and can easily be reused for other processes.
iv) Installing a heat exchanger system can help make use of this water.
v) Reuse of steam condensate, This water can serve as a water supply for washing or de-sizing. The reuse of condensate can help save a substantial amount of energy and water.
vi) Recover heat from hot rinse water and hot gases.The heat from rinse water can be captured and used to preheat the incoming water for the next rinse. A plate heat exchanger can transfer wastewater heat energy to incoming cold fresh water.
vii) Maintain steam traps that remove moisture, and prevent condensation thus reducing heat loss and overall fuel consumption. Poorly maintained steam traps will lead to unwanted steam loss into the condensate system and so increase heat loss and fuel consumption. Regular inspection, repair, and replacement of steam traps are required.
viii) Compressed air, Regular checking of threaded connection points, rubber hose connections, valves, regulators, seals and old pneumatic equipment. Use low-pressure air for cleaning purposes. Keep optimum air pressure. Discourage poor practices using compressed air. Use of Centrifugal compressor in place of screw compressor
ix) Insulation of pipes, valves, and flanges. Routine checking of insulation of pipe, valve, and flange throughout the year is a must.
x) Reduction of effluent loading. The cost of effluent treatment is directly related to the volume of effluent and the concentration of chemicals present in that effluent. Water reduction will help in reducing the volume of effluent.
xi) Reduction of chemical usage and increase of dye fixation will help in reducing total effluent loading.
xii) Use of AC drives can reduce electricity power consumption significantly compared to DC drives.
xiii) Use of biomass in the boiler as basic raw material in lieu of fossil fuel coal.
xiv) Installation of LED lighting arrangement.
xv) Use of Green sustainable fuel of high calorific value in place of fossil fuel wherever fuel is used.
The benefits of a Sustainability drive are
i) Enhancement of image, reputation, and brand recognition
ii) Increase in competitive advantage
iii) Increase in business ability to comply with regulation
iv) Attraction of employees and investors
v) Reduction of wasting
vi) Retain top talent and increase in employee satisfaction
vii) Reduction in operating and manufacturing costs leading to improved company’s bottom line.
