Waste management is nothing but all the activities and actions required to manage waste from its inception to its final disposal.
The raw materials in various combinations undergo different processes during production and are converted to finished goods.
The trash left out after each process during production remains waste. Waste Management is the human control of the collection, treatment, and disposal of different wastes.
This is in order to reduce the negative impacts on environment and society. Waste is directly linked to the human development, both technologically and socially.
The compositions of different wastes have varied over time and location, with industrial development and innovation being directly linked to waste materials.
Examples of this include plastics and nuclear technology. Some components of waste have economic value and can be recycled once correctly recovered.
Therefore, it is very important to minimize its impact on the environment by establishing a proper waste management system.
This review discusses cotton textile processing and methods of treating effluent in the textile industry.
Textile industry plays a vital role in the economy of the country like India and it accounts for around one-third of total export.
Traditionally produced fabric contains chemical residues, used during their manufacturing. These chemical residues may evaporate in the air or may absorb through our skin thus causing allergy.
According to a June 5, 2005, article in the business week, the population allergic to chemicals will grow to 60% by the year 2020.
The list contains frequently used terms in the waste industry or in a waste management system. Airspace, baler, boiler, brownfield development, capping, cell, close site, closure, construction and demolition, commercial customer, container, chemical waste management, daily cover, disposal fee, drop off box and dumpster.
“Unwanted or undesired material or substance is Waste.”
Maximum utility of Resource and Raw material, in order to bring maximum profit to an organization, is Management.
An essential consumer goods industry is Textile Industry and one of the most polluting industries. Higher the production is, the greater the amount of waste.
3R’s Recycling Reuse Reproduction The different types of wastes. Prevention of waste at source must be the way of the future.
Why Should We Manage Waste?
- Protects Environment.
- Recycling Makes Extra Money.
- Reduce Waste.
- Saving Resources And Energy.
- Reducing Pollution.
- Increasing The Efficiency Of Production.
Reasons For Waste Generation
- Worker’s Skills.
Effects On Human Health
- Mutagenic And Carcinogenic Diseases.
- Allergic Contact Dermatitis.
- Birth Defects.
- Contraction Of Blood Vessels.
- Mental Distress.
Human Hazards From Different Gases
|1||CO||Reacts with blood and forms carboxyhaemoglobin.|
|2||Oxides of nitrogen||Bronchitis, eye irritation.|
|3||Sulphates||Eye irritation, breathing problem.|
|5||CO2||Nausea, increase in global T|
Effects On Environment
- Aquatic saprophyte and Algae.
- Pollution of soil.
- Water pollution.
- Air pollution by the emission of gases.
Waste Generation During Processing
Types Of Waste In Textile And Garment Industry
- Hard Waste
- Cut Yarns
- Cut Fibres
- Cutting Waste
- Sewing Waste
How Do We Manage Waste?
Effluent Treatment Plants (ETPs)
Methods Of Treatment
- Primary Treatment.
- Secondary Treatment.
- Tertiary Treatment.
Advanced Methods For Treatment
- Ion Exchange.
- Membrane Filtration.
It can be done by three ways
- Reverse osmosis.
- Specific Treatments.
Filtration Spectrum Of Different Membranes
|Process||Pore Size (micron)||Molecular Weight||Examples|
|Microfiltration||0.007- 2.00||> 100000||Bacteria, pigments, oil etc.|
|Ultrafiltration||0.002- 0.10||1000 – 200000||Coloids, virus, protein, etc.|
|Nanofiltration||0.001- 0.07||180 – 15000||Dyes, pesticides, divalent ions etc.|
|Reverse Osmosis||< 0.001||< 200||Salts and ions.|
Combined Effluent Treatment
Importance Of ETPs
- The main function of this plant is to clean GCP effluent and recycle it for further use.
- Converts entire quantity of effluent to zero level.
- Treatment is based on the removal of entire BOD/COD.
- To reduce the possibility of pollution.
- To provide some degrees of wastewater before it can be used.
Benefits Of Waste Management
Improving waste management can benefit business and environment by
- Reducing the cost of purchasing materials.
- Increasing profitability.
- Minimising solid waste treatment and disposal costs.
- Improving wastewater quality and reducing treatment costs.
- Reducing environmental impacts by reducing the use of raw materials and producing less waste.
- Improving your public image and employee satisfaction through promoting an environmentally responsible image and providing a safer workplace.
