A detailed discussion on the sources and impacts of waste materials is given below.
> Source of waste material:
The sources of waste materials in the environment are various – these sources are mainly as follows:
1. Settlement or residential area:
Food waste:
Leftovers after cooking, old food, discarded fruits and vegetables etc.
packaging materials: paper, plastic, glass and metal container residues.
household waste: old clothes, furniture, batteries, electronic components etc.
industry sector:
2. Processing waste:
Chemicals, dust, oil and other hazardous substances from industrial production processes.
Manufacturing waste: metal, glass, plastic etc. are wastes from various industries.
agricultural sector:
3. Agricultural residues:
Plants, leaves, and other wastes mixed with the soil left after harvesting.
4. Chemical waste:
Residues of fertilizers, pesticides and other chemicals.
5. Healthcare sector:
Medical waste:
Used equipment, injections, medical equipment, medicine-related waste from hospitals and clinics, such as cotton, gauze, bandages, various lethal parts in surgery
.> Commercial sector:
1.Commercial waste:
Plastic bags from shops, markets, packaging materials, leftover food.
2.Effects of waste materials:
Waste materials affect the environment, human health and the economy in a variety of ways. these effects are discussed in detail below:
>Environmental impact:
1. Soil pollution:
Waste materials, especially chemicals and hazardous wastes, mix with soil and degrade soil quality. this makes the soil less fertile and damages the agricultural production
2. Water pollution:
Water is polluted when waste materials enter water bodies, rivers or seas. it affects aquatic life and degrades water quality, which is also harmful to human health.
3. Air pollution:
Incineration of solid waste releases harmful gases and particulates into the air. this pollution causes global warming and other environmental problems. it results in various lung diseases.
> Health effects of various diseases increase:
1. Spread of disease:
Unused or neglected waste can become a breeding ground for mosquitoes, insects and other pathogens, which spread various diseases
2. Special health problems:
Harmful chemicals released from waste can enter the human body and cause various health problems, such as cancer, respiratory problems, etc.
economic impact:
3. Waste management cost:
A huge amount of money is spent on waste organization, transportation and disposal. this cost becomes a burden on the public and private sectors.
4. Waste of resources:
Waste that can be reused or recycled is a waste of valuable resources if not properly managed.
> There are various management and solutions to reduce the negative impact of waste materials
1. Waste reduction:
Efforts should be made to reduce waste at the production stage. for example, using recycled materials. to keep the environment free from pollution some products have to be completely rejected, like plastic, thermocol etc.
2. Reuse and recycling:
Minimize waste by reusing recyclable materials and collecting valuable materials by recycling, such as creating beautiful home decor items from a variety of essential items rather than throwing them away after one use
3. Composting:
Enhancing soil fertility by turning organic waste such as food waste and plant waste into compost. the composting method is similar to the filling method. in this method, a pit is filled with some amount of organic waste such as animal carcasses, household and market scraps and rotten vegetables, excrement, etc. and the mouth of the pit is closed with soil. the pellets are decomposed to form organic manure, which has high nutritional value.
4. Waste management technology:
Process and dispose of waste by developing improved waste management technologies and policies
5. Raising public awareness:
To create awareness among people about the importance of waste management and how to reduce waste.
In conclusion, waste materials are a serious environmental and health problem. its impact can be minimized with proper management and awareness. government policies, technology and people''s participation play important roles in this rega
