Leather Wet Blue

Following are some of the best available techniques that can not only reduce your environmental footprint but can also contribute to increase your process efficiency leading to reduced overall costs.

  • Installation of water flow meters at all water supplies and maintain water consumption records on monthly basis
  • Insulate the surfaces above 50°C with optimum thickness
  • Remove redundant utility lines and optimize the routing of utilities
  • Plan evaluation of efficiencies of utilities (Boiler, Generator, Compressors, etc) generation, distribution and utilization on periodic basis
  • Inspect the steam, hot water, freshwater, compressed air lines and fittings for any leakages
  • Use desalting drums
  • Switch to new technology of tanning drums
  • Switch from continuous, “running water washes” to batch washes
  • Water used in washing hides before the Main Soaking process can be collected and reused in Pre-Soaking.
  • The water used in the liming process can be reused in next liming process batch after filtration. The pollution loads up to 70% of Sulfate [S2-] and 93% of Lime [Ca(OH)2] load can easily be reduced, which can contribute in reducing 7% load of BOD and 26% load of COD in overall wastewater at end of pipe.
  • Water used in Deliming washing can be collected and reused in Post Liming.
  • Water used in Post Deliming & Bating washing can be collected and reused in Pre-Soaking wash.
  • Carbon dioxide deliming can be used to neutralized lime it decreases pollution load of effluents if feasible
  • Wetback water can be collected and reused in next Wetback lot
  • Water from washing of Wetback can be collected and reused in wetback of successive lot
  • Reuse of pickling and tanning floats in successive cycles
  • Rechroming Water which is drained to waste after completing the process can be collected and recycled back for the rechroming of next lot or can be directed towards in house chrome recovery plant.
  • Post Neutralization Washing Water can be collected and reused as Neutralization Water for the next lot.
  • Recycle cooling water from Machines like Vacuum Press, Sammying, pumps, compressors etc.
  • Curing salt that is attached to the raw hides [Cow, Buffalo] and skins [goat] can be recovered and reused. It is estimated that 50 kg of salt can be obtained from desalting 1,000 kg of raw stock.
  • Decrease the amount of salt used to preserve hides by adding some environmentally acceptable antiseptics (boric acid, acetic acid and sodium suplhide) or commercial bactericides based mainly on ethyldithiocarbamate and isthiazolin. Pollution load in soaking wastewater is reduce to 50%.
  • Processing of green hides (unsalted fresh hides) is preferred if cooling and chilling is feasible.
  • Dyes containing hazardous heavy metals such as lead, cadmium, and chrome VI shall be avoided.
  • Fat liquoring agents based on chlorinated paraffins shall be avoided and other environmental friendly synthetic fat liquors should be used
  • Benzidine and other azo-dyes which may be reduced to carcinogenic amines should be avoided.
  • Avoid finishing operations with pigments containing environmentally hazardous heavy metals and other restricted products
  • Whenever possible use water-based finishes/solvents
  • Use of Solar water heating for process water heating
  • Use solar air drying for hides and skins wherever possible
  • Integration of photovoltaic in existing power supplies available
  • Build training routines for staff at all hierarchical levels

Climate change is a major environmental issue. The world is facing climate change level where there is no point of return. This article highlights few facts about climate change and few solutions.

Facts:

Few facts about climate change are as follows:

  • Two hundred & eighty six billion (286,000,000,000) tons of ice is being lost every year in the areas of Greenland and Antarctica
  • There have been a reduction in the snow cover in the northern hemisphere in last five decades
  • There has been an increase  of eight inches (8 in) in the global sea level
  • The frequency of extreme weather events i.e. flooding, hurricanes, tornadoes have been on increase.
  • There has been an increase of ocean acidity by thirty percent (30%)
  • The temperature of upper twenty three hundred (2300) feet of ocean have been raised by 0.4 degree Fahrenheit (°F)
  • There has been an increase of 1.6 degree increase in temperature of earth atmosphere due to the continuously increasing level of greenhouse gases.
  • Since 2010, there have been five (5) warmest years on record. 2019 as well have been the warmest year. Germany have faced historic high temperature.
  • The present-day warming trend on the earth is ten times greater than the past warming trends recorded at the end of an ice age.
  • In the Himalayan a glacial retreat mountains have been observed by the scientist
  • The intensity and frequency of wildfires have been on increase globally. Amazon rain forest have been burning since 3 weeks up-till now.
  • The Indonesian capital city is being moved because it was sinking due to the ever increasing sea levels.
  • In last forty year, sixty percent (60%) drop in wild life have been observed.
  • The carbon emissions have been increasing on our planet since 2011.
  • Tropical forest are facing destruction continuously due to anthropogenic activities
  • It is has been estimated by scientists that there are ninety-five percent (95%) chances that climate change is due to anthropogenic activities.

Solutions:

According to scientist climate change can be slowed down to it natural level. Level where everyone gets a chance to adopt to the changing environments. Few of the solutions that you as an individual can adopt to help control climate change are as follows:

  • Use public transport instead of using your own cars all the time
  • Switch your vehicle to environment friendly fuels e.g.  electric or hybrid vehicles
  • Invest in the renewable energy e.g wind , solar, biogas, geothermal etc.
  • Encourage legislation which discourages the use of fossil fuels.
  • Use energy efficient lights, fans, AC invertors and decrease energy losses in the house
  • Garments can be washed in cold water instead of hot water to save energy.
  • Basic food/vegetables can be grown in your own house (roof gardening)
  • Plant trees and also encourage other to plant more and more trees
  • Buy local items
  • Buy garments, which are more sustainable.

We as individuals needs to do more and change our pattern of life so that we can protect the planet for ourselves and our future generations.

Benefits of Becoming a Sustainable Business

Sustainability is not simply a trend, and therefore the international community has touched on the far side of the “going green” motto. Sustainability could be a universal, long-run approach to only solely manage environmental risks, however social and financial risks as well. A sustainable business consists of three sphere knows as triple bottom line (3Ps) i.e. People, plant and profits.

If you take sustainability approach, it means that your business has no significant negative impacts on the society and environment while your organization is flourishing financially. Sustainability approach encourages organizations to concentrate on long term objective, targets & strategies, and it can offer a wide range of benefits in return.

For organizations to accept the sustainability model and take it  as a serious business strategy, we must be able to define and quantify the business benefits that can be achieved from this strategy. Then it can become criteria to measure the success of the organization, because as with any other model, return on investment is ultimate measurement of success.

Improved brand image and competitive advantage

In one study conducted by Natural Marketing Institute from more than 53000  US consumers, it was revealed that 58% consumer consider the impact of an organization on environment before choosing to purchase any goods or services from  it and are more intended to purchase from organization with sustainability approaches incorporated in their system. This leads to approximately 68 million on American clients who favor those companies that have good track record in social and environmental values.

It was also found that these consumers were willing to spend even 20% more on products that are environment friendly. Brand awareness and image building is becoming increasingly important. Creating awareness campaigns like water or energy conservation or paper conservation not only conserve resources but also improves awareness about brand.

Productivity increase and cost reduction:

The people critical of sustainability approaches claim that these practices can reduce the corporate profits. But in reality if we develop sustainable business practices, it leads towards operational efficiency improvement due to streamlines efforts, resource conservation, which enhances employ productivity and reduces costs. Cost reduction can also achieved through energy conservation by few simple practices likes switching off un-neccessory lights and appliances and using energy efficient equipment. Sustainable practices might have huge initial investment but long terms results will justify the investment.

Compliance with regulations:

As with the increase of awareness about climate change, global warming, reduced energy resources and other environmental impacts, governments are increasingly trying to develop and enact different regulations to protect and conserve environment. If an organization integrates sustainability into its business, the organization will be in a position to meet the always changing regulations.

Attract employees and investors.

People, especially the young generation is attracted towards organizations who work on environmental conservation as they have been raised in an environment where there is continues message of environmental protection/activism and does not want to work with organization who have environmental disasters and social scandals. Presenting your organization as respectful to environment and employees/society will not only attract component people but will also attract investors.

Waste Reduction:

Waste reduction is the most common and simple way to encourage organization to be engage in sustainable practices. Utilization of 4Rs technique to reduce the solid wastes, replacement of energy efficient equipment’s to reduce energy waste.

Minimize Carbon Risk and Improve Energy Efficiency

It is expected from all companies to cut down 25% of their Carbon emission till 2020 and further cut down 50 to 80% till 2050, which will become mandatory by Law. This will also effect the cost and availability of electricity.
