As plastic consumption continues to increase around the world, plastic waste has become a major environmental concern. Plastic waste pollutes our oceans and harms marine life, disrupts ecosystems, and contributes to global climate change. One effective solution to this problem is plastic recycling. In this article, we will explore the importance of plastic recycling, its benefits, and the challenges it faces.

What is Plastic Recycling?

Plastic recycling is the process of converting used plastic products into new materials. This process involves collecting, sorting, cleaning, and processing plastic waste. Once processed, recycled plastic can be used to make various products such as furniture, clothing, and new packaging. Very few types of plastic waste which can not be recycled are sent to cement kilns, Road Construction & Pyrolysis.

Challenges in plastic recycling

• Lack of awareness leads to the mixing of all kinds of waste
• Due to plastic density, it occupies more space and costs double to transport
• Plastic requires manual segregation before recycling. Lack of infrastructure and government policies
• Myths and lack of recycled plastic products acceptance in-market lead to more plastic waste in landfills

Stages in plastic waste recycling

Recycling of plastic waste consists of the following stages:

• Collection: Plastic waste is collected from various collection sources like Rag Pickers, municipalities, Societies, Kabadiwalas, and Awareness Drives.
• Sorting: Collected plastic waste needs to be sorted accordingly so it can be processed further in the shredding machine
• Washing: Sorted plastic waste usually contains dust, adhesive, and more impurities that must be washed away. This is done in the washing line at the recycling facility.
• Shredding: Once segregated and washed now plastic is shredded into smaller pieces by the process of shredding.
• Identification and Classification of Plastic: After shredding, proper testing of the plastic pellets are conducted in order to ascertain their quality and class.
• Extruding: Running on the line next step is extrusion, In this process, shredded plastic waste is melted and extruded, and converted to plastic granules. Also In order to enhance the properties of the material, even some extra filling is added to the material

 

 

 

Advantages of Plastic Recycling

Knowing the process of recycling it does not only helps us manage waste but also contributes to a better and safer environment.

• The huge amount of plastic production: Plastic is used for manufacturing households and goods which are used on a daily basis, there is more plastic in our garbage than any other type of plastic. Recycling puts the same plastic waste in the circular economy.
• Conservation of Energy and Natural Resources: virgin plastic requires resources like chemicals and production energy recycled plastic granules can full fill the demand for plastic granules for plastic products manufacturing and helps conserve energy and natural resources.
• Clears Landfill Space:  Plastic waste accumulated makes huge piles of plastic waste on the landfill as the plastic takes ages to decompose fills up landfills which further causes the release of toxic air and pollution leading to diseases.

Plastic recycling not only promotes proper waste management of plastic waste but also helps conserve the environment.

Benefits of Plastic Recycling

Reducing Plastic Waste

Plastic waste is a significant problem around the world. By recycling plastic, we can reduce the amount of plastic that ends up in landfills, oceans, and other natural habitats.

Conserving Resources

Recycling plastic helps to conserve natural resources such as oil, gas, and water. These resources are used to produce new plastic products, and by recycling plastic, we can reduce the need for new materials.

Saving Energy

Recycling plastic also saves energy. It takes less energy to recycle plastic than it does to produce new plastic from raw materials. This is because recycled plastic has already been processed and can be melted down and reused.

Reducing Carbon Emissions

Plastic recycling can also help reduce greenhouse gas emissions. The production of new plastic products generates a significant amount of carbon emissions. By recycling plastic, we can reduce the demand for new plastic products and, in turn, reduce carbon emissions.

Processes of Recycling & Disposal Of Non-Recyclable

Very few types of plastic waste which can not be recycled are sent to cement kilns, Road Construction & Pyrolysis

• Pyrolisis: Pyrolysis generally consists of heating the material above its decomposition temperature, and breaking chemical bonds in its molecules.
• Cement Kilns: Plastic waste that can not be recycled anymore are sent to cement kilns.

Challenges of Plastic Recycling

Despite its benefits, plastic recycling faces several challenges. These challenges include:

Contamination

Contamination is a major issue in plastic recycling. Contaminated plastic is difficult to recycle and can negatively impact the quality of recycled plastic. This is why it is important to properly clean and sort plastic waste before recycling.

Low Market Demand for Recycled Plastic

Another challenge of plastic recycling is the low market demand for recycled plastic. Many companies prefer to use new plastic rather than recycled plastic, which can make it difficult for recycled plastic to compete.

High Costs of Recycling

Recycling plastic can be expensive. This is because it requires specialized equipment and facilities, as well as skilled workers. The cost of recycling can also vary depending on the type of plastic being recycled.

Types of Plastic Recycling

There are three main types of plastic recycling:

Mechanical Recycling

Mechanical recycling is the most common form of plastic recycling. This process involves grinding and melting down plastic waste to create new plastic products.

Chemical Recycling

Chemical recycling is a newer form of plastic recycling that involves breaking down plastic into its chemical components. These components can then be used to create new plastic products.

Biological Recycling

Biological recycling is a relatively new form of plastic recycling that involves using microorganisms to break down plastic waste. This process can produce biodegradable plastics that are better for the environment.

How to Recycle Plastic

Recycling plastic is easy. The first step is to properly sort your plastic waste. Once sorted, you can take your plastic waste to a recycling facility or use curbside recycling if it is available in your area. Make sure to follow the recycling guidelines provided by your local recycling program to ensure that your plastic waste is recycled properly.

Innovations in Plastic Recycling

In recent years, there have been several innovations in plastic recycling technology. These innovations include:

• Advanced Sorting Technologies: New technologies are being developed to improve the sorting of plastic waste. These technologies can help reduce contamination and improve the quality of recycled plastic.
• Chemical Recycling: Chemical recycling is a promising technology that can turn plastic waste into new materials with higher value. This technology can convert plastic waste into fuels, chemicals, and even new plastic products.
• Bioplastics: Bioplastics are a type of plastic that is made from renewable resources, such as plants. These plastics are biodegradable and can help reduce plastic waste.
• Recycling Robots: Recycling robots are being developed to automate the sorting and processing of plastic waste. These robots can improve the efficiency and reduce the cost of plastic recycling.

Conclusion

Plastic recycling is an essential solution to our planet’s plastic waste problem. By recycling plastic, we can reduce plastic waste, conserve resources, save energy, and reduce carbon emissions. However, plastic recycling also faces challenges such as contamination, low market demand, and high costs. Despite these challenges, innovations in plastic recycling technology are providing new opportunities to improve the efficiency and sustainability of plastic recycling.
