Sludge Recycle – We have been trying through our Environmental Team since 2011 to minimize all types of waste generation & manage our waster as per law. Recently, we have an MOU (Memorandum of Understanding) with Lafarge Cement Factory regarding our sludge wastes. They have been through experiments if industrial ETP sludge could be used in cement manufacturing. Experiments showed light and they have successfully used the sludge in making cement. Now, we agree to come to a point of industrial symbiosis with sludge. We hope this negotiation will be fruitful very soon.
Development is a never-ending continuous process. We must keep pace with this process to bring about better changes. We are thinking and evaluating the chance of reduction, reuse & recycle of every waste material we generate. Salt recovery from used water is under active consideration. We would like to follow national rules & regulations and apply any contemporary changes to save water. We have a better Environmental Team, which is working relentlessly in this regard.
We took initiative if our ETP sludge could be used in making bricks. We ran this experiment with the help of a brick company. The brick company successfully made brick using the sludge. We sent this brick to BUET for compatibility test. Hopefully, the brick passed all the tests and it was no less than the ordinary bricks. Now, we need more accomplishment from brick factories & proper authorities like DOE so that an official approach is made to use such available waste, which may save resources, money & valuable time. Brick factories need huge amount of soil every day to make bricks. Use of sludge for brick making purpose from hundreds of factories may lessen impact on our natural soil & land.
Auto Textile has got state of the art facilities in terms of water management and disposal of sludge. The amount of water we use has got a control through the use of flow meter and the liquor ratio is also imposed by another set of water flow meter in the dyeing machines. As a part of our commitment to the environment and our next generation we use the highest quality of dyes and chemicals in our dyeing and printing factory. The dyeing section even uses software which is connected to the chemical store where the chemicals and dyes are disposed automatically through the use of automatic dispensing machine and auto sensor respective by. In case of the water, the company brings back the dyeing laboratory’s waste water; printing factory’s washing water and washing unit’s water to the ETP.
In ETP which AUTO TEXTILE runs 24 hours use state of the art laboratory material for the measurement of the Do, TDS and to keep them safe for the environment. ETP is maintained by a well-trained group of personnel in 3 shifts and chemical has been dozed as per the requirement of the coloration of water. Every shift these person take the measurement and keep those data in the register. If there is any problem in the measurement a standby resource, dyeing lab is nearby to solve it as it is also open for 24 hours.
As a last ETP Audit Report , AUTO TEXTILE also has a contact of a numerous experts to help online via mail or cell. Moreover the owner of this facility himself is a textile Engineer and a re-known person for his contribution to the Mother Nature in terms of recycling, innovation and conservation.
For the sludge disposal AUTO TEXTILE has a contract with four star bricks to use them to make bricks which is burnt more than 15000C. By doing this, we are saving our mother nature and for the next generation. Finally AUTO TEXTILE has decided to move along with the latest technology by contracting a company for the total automatic of the ETP. They are working on it and will be coming with a final quotation very soon. We hope that in near future we will use less energy to run ETP with zero discharge in the environment.
Sludge Recycle of Polythene & Cartons
We procure yarn, dyes, chemicals & other textiles auxiliaries from home and abroad, which are frequently procured & used. Materials, which we buy, are well covered with polythene & cartons. These polythene & cartons are left over after use & the daily-generated amount is not small. We recycle this polythene waste to reproduce polythene again. We also partially use the cartons to make cartons. It saves our money and the wastes are well disposed of.
Reuse of waste yarn
Yarn is the primary / direct raw materials of knitting fabric. Huge amount of yarn is used every day. Some yarn is always left over with the cones, which is not need after the completion of production. The amount is not small. We collect & accumulate these cones and sort them out to reuse.
Conclusion
Sludge Recycle – We use this scrap yarn to make fabric sack, which is always used within our factory premises to move raw fabric roll from one section to another. This Reuse initiative helps us to get rid of our waste-yarn and saves our money.
Methods of waste management – Fabric processing is a continuous process to run. One process is followed by another. Raw fabric is produced from yarn. Afterwards, this raw fabric is processed and finished to make complete garment fabric. Engagement of huge chemicals, dyes and water results complete fabric. Therefore, generation of waste follows every step of fabric production. We need ETP Audit Report
There are other sources of waste, which are not directly associated with fabric processing, but they help to run and control the production cycle. These sources are like Human Resource Development (HRD) Department, Maintenance Department, and Store Department etc. In the following tables, we have gathered the lists of almost all wastes generated from all sections or departments
Waste management is a big issue for any organization. No single department or section can handle this giant job all alone. Therefore, we have an Environment Management Team (EMT) to deal with environmental issues such as waste management. The main job of this team is to integrate all necessary people from all concerned departments in a single platform so that they can think alike regarding environmental management system. The existence of this team has made the job easier for Auto Textiles Ltd. to establish a better water management system.
Department of Environment (DOE) has formed some specific norms and regulations for industrial sectors regarding environmental pollution and control to keep the environment healthy. These rules & regulations are followed as general guidelines all over the country. We respect these rules and we are already following to comply with national rules, regulations and law. It is very difficult to run business in an environmental manner in a country like Bangladesh where lack of awareness and technological backwardness are never ending problems to deal with. Moreover, a better waste management system is only possible after combined integrated efforts from all concerned departments. Firstly, we have classified our wastes according to their nature & properties. Afterwards, we have enlisted all the wastes from all departments or sections we are dealing with. Then, we have decided the right disposal procedure for each waste. , we have already taken some research & development initiatives for the best wastewater management. However, we are putting all are combined efforts to manage our wastes. The followings are the procedural measures that we are following to materialize better waste management system:
Industrial Waste Management -Waste management is a big challenge for any organization.has developed some principles in relation to waste management so that things become systemic and easier. Those Methods of Waste Management are as follows-
Source Reduction / Prevention: Reduction or preventing waste generation from the very beginning of the production process is perfect better waste management. Reduction is using items or materials with care to reduce the amount of waste. Source reduction methods involve changes in manufacturing technology, raw material inputs, and product formulation.
Reuse: Reusing involves the repeated use of items or parts and materials which still have usable aspects. Checking, cleaning, repairing, and refurbishing whole items or spare parts minimizes waste and increases economic efficiency substantially.
Recycle: Recycling means using generated wastes as resources or secondary materials for making further products or materials. Recycling helps to save energy, resources using materials again, and turning wastes into new substance or products.
Resource Conservation: Resources, both natural and manmade, are limited though its demand is always increasing. Best Environmental Practices (BEP) should be encouraged & implemented for sustainable business activities. Therefore, better practices of waste management may help us to save our resources and energy largely.
Industrial Waste Management Segregation: Wastes may become resources if properly utilized. Wastes need to segregated or separated according to their types and property to reuse or recycle. Some wastes are hazardous and some are low or semi hazardous. Hazardous wastes require specific treatment or disposal procedure other than non-hazardous wastes. Hazardous wastes may contaminate or deteriorate the potential of reuse or recycle of other wastes. That is why proper waste segregation is necessary for better waste management.
The above-mentioned principles are followed and considered whenever any decision & action is taken regarding waste management.
After huge production, huge resonsibility falls upon our shoulder to manage it. However, ATL is committed to follow the guidelines of Environment Conservation Act, 1997 (ECR’97) and its own Enviroonment Management System (EMS) with a view to maximize the use of resources, minimize waste generation and manage various wastes properly in its own premises. Describe Methods of Waste Management
Development is continuous process and production of products & goods cannot be hampered drastically to minimize or stop waste generation. Waste generation cannot be ignored rather it has to be managed accordingly. As a Environment Concerned unit, is committed to engage all necessary efforts to manage wastes to keep the concerned stakeholders & environment clean and sound. We hope that we would be able to integrate our production activities and form an Environment Management System for the best waste management in the industrial neighbourhood. The main pillars of the waste management system are mentioned below–
Comparison with the best:
Evry concerned about environment, health & safety. We are doing our best to do our business in an environmentally friendly manner. There are other business concerns, which are burning examples of Best Environmental Practices (BEP). Our buyers and government authorities often show us the best ways to manage our wastes. We always compare ourselves with the best so that we can figure out our weakness and opportunity in order to develop environmentally friendly business manners and keep our environment cleaner & healthier than others.
Statement of the issue:
Various types of raw materials, chemicals, dyes are used to process raw fabric. The more materials are used, the more wastes are generated every day. We always try to figure out where and how waste can be minimized and what should be the proper disposal procedure. Accurate and complete information helps to take proper step regarding any management action let alone waste management. What is not measured cannot be managed. There are different properties and parameters to measure the concentration and pollution extent of waste. Therefore, proper record keeping of wastes and availability of necessary information are very crucial in better waste management.
Analysis of Waste Management Issue:
Nowadays almost all the organization around the world are more or less aware of environmental responsibilities. Various movements regarding different environmental issues are being carried out by different profit & non-profit organizations who work for the wellbeing of the environment- home and abroad. We always welcome recommendations coming from buyers and other organizations. We evaluate the recommendations and implement where it is possible to apply them. We have established a waste management system to manage all our wastes. We try our level best to deal with any waste related issue. Whenever we face obstacles or issue, we ( the Environmental Management Team) sit together and discuss about the present or upcoming issue. After brainstorming & analysis of the topic, we try to figure out the possible & viable solution from the several options.
Initiatives taken by other textile enterprises
This above-mentioned planning process is followed by our Environmental Management Team to form and run a better waste management system. Waste Management is a lengthy initiative, which cannot be established so quickly. There may be other organizations, which are very cautious about environment and exercise good waste management practices. We follow them to develop or improve our own management system.
Methods of Waste Management -Production of necessary products & goods is increasing everywhere around the world with a view to keep pace with increasing human demand. Our natural resources are limited. After utilizing resources, production processes give off various unwanted materials or wastes, which cannot stopped or ignored. Products and wastes are like the two opposite sides of a coin; one cannot leave other. Read about Principles of Industrial Waste Management
Complete and useful products are consumed very easily whereas left over unwanted materials or wastes need to be taken care of to keep the environment clean and sound. With the advancement of time, people are becoming more aware of environmental protection, conservation and sustainability. As an Environment concerned business unit of Auto Group, Auto Textiles Limited is committed to do business in an eco-friendly manner. We are ready to comply with all rules and legislation regarding environment, health & safety. The main objective of this Environment Management System or Waste Management System is to manage all our wastes according to Environment Conservation Act, 1997 (ECR’97) to do production/ business activities in a safer way and keep the surrounding environmentally friendly. Actually, waste management should go beyond pollution prevention and disease prevention for humans. Furthermore, it should benefit society by providing economic gain for organizations, communities and families. The preferred approach for dealing with waste is Integrated Waste management (IWM). ISWM means considering not only the appropriate disposal of wastes but integrating this with other management options such as minimizing waste production, recycling, composting and other waste recovery options. The advantages of IWM are that we can consider all options and aim to manage wastes in ways that are most effective in protecting human health and the environment. IWM can also have many economic and
Waste Classification:
Wastes may become resources if they are properly segregated and utilized. Different wastes have different properties. Waste treatment procedures follow those properties to manage that waste. We have classified all our wastes according to different points of view. Depending on the states of the wastes, wastes are classified as-
Solid Waste (solid in nature),
Liquid Waste (such as wastewater that is mixed with different dyes & chemicals),
Gaseous Waste (Smoke or gas emitted from combustion channels like generators, boilers, dryers etc.).
According to the potential degree of hazard, wastes have been classified as-
Hazardous Waste (H)
Low – hazardous Waste (L H)
Non – hazardous Waste (N H)
According to production point of view, wastes has also been classified as-
Production Waste (Generated directly from production process).
Non Production Waste (Not directly associated with production).
Conclusion
Methods of Waste Management is not a waste until it is properly disposed of. It can be either a resource or a hazard. That is why it has to be segregated as resource material or hazard substance as early as possible. Hazardous wastes should be separated from other wastes since hazardous waste may contaminate the potential of non-hazardous wastes.
