Recycling of plastic

Plastic is an important part of our everyday lives. We use it in many things like toys, bottles, bags, and even clothes. But have you ever wondered what happens to all these plastic items once we are done using them? This is where the concept of plastic recycling comes in. Plastic recycling is important because it helps us reduce waste, save energy, and protect the environment.

What is plastic?

Before we get into recycling, let's understand what plastic is. Plastic is a synthetic material made from a wide range of organic polymers such as polyethylene, PVC, nylon, etc. They are mainly derived from natural gas and crude oil. Plastics are known to be strong, lightweight, flexible and resistant to moisture. However, their durability is both an advantage and a problem. In nature they can take hundreds of years to decompose.

Types of plastic

There are many types of plastic, but some common types are:

• Polyethylene terephthalate (PET or PETE): Used for bottles and containers.
• High-density polyethylene (HDPE): Used for milk jugs and detergent bottles.
• Polyvinyl chloride (PVC): Used for pipe and cable insulation.
• Low Density Polyethylene (LDPE): Used for bags and wrapping.
• Polypropylene (PP): Used in packaging, textiles, and automotive components.
• Polystyrene (PS): Used for foam cups and insulation.

Why recycle plastic?

Recycling plastics is important for several reasons:

1. Environmental Protection: Reduces the amount of waste in landfills and oceans.
2. Conservation of resources: Raw materials and energy used to produce new plastic are saved.
3. Reduces pollution: Helps reduce harmful emissions caused by the manufacturing of plastic.

Recycling process

The plastic recycling process involves several steps. Here's how it typically works:

1. Collection

The first step is to collect plastic waste through recycling bins or recycling centers. This is the part where households and businesses should properly sort their plastic waste.

2. Pruning

Once the plastic is collected, it has to be sorted according to type. This is important because different types of plastic need to be handled differently in recycling. Sorting can be done manually or using machines.

3. Cleaning

The sorted plastic is then cleaned to remove impurities such as labels, adhesives or leftover product. This ensures that the plastic is ready to be melted.

4. Shredding

Clear plastic is cut into smaller pieces, making the next step easier. This way, large items are broken down into manageable pieces.

5. Melt and reshape

Small plastic pieces are melted and shaped into pellets. These pellets are the raw material used in the manufacture of new plastic products.

Real-life example

Consider how a plastic bottle changes after it is recycled. It starts out as part of a soda bottle. Once discarded, someone tosses it into a recycling bin. After collection, it is sorted, cleaned, cut into smaller pieces, melted, and finally turned into another useful product, such as a new bottle or even a plastic toy.

Challenges in plastic recycling

Recycling plastic is very beneficial, but it also has challenges:

• Contamination: Not all plastics that come in for recycling are clean. Food waste, labels and adhesives can cause problems.
• Cost: Recycling can be expensive, especially when compared to making new plastic from raw materials.
• Different plastic types: Each type requires a specific recycling method, which can complicate the process.

Impact on the environment

Successfully recycling plastic has a positive impact on the environment. It reduces landfill overflows, reduces the need for new plastic production, saves resources and energy, and reduces pollution and greenhouse gas emissions.

Everyday examples

To understand plastic recycling, let's look at some relevant examples:

• Laundry detergent bottles made from recycled HDPE can be recycled to make plastic lumber or new detergent bottles.
• Felt tip pens or plastic rulers can be produced from recycled plastic items such as yogurt containers.

How can you help?

Individually, we play an important role in recycling plastic. Here are some simple ways you can help:

• Always sort and clean your plastic waste before disposing of it.
• Reuse plastic items wherever possible instead of throwing them away.
• Support policies and companies that promote recycling and sustainability.

Conclusion

Recycling plastic is a vital part of managing our world's waste and protecting our environment. By understanding the process and contributing in small ways, each of us can make a significant impact. Remember, the Earth is our only home and it is everyone's responsibility to take care of it.
