Plastic is found in bottles, containers, packaging materials, and other daily necessities. Plastic is flexible and versatile because it is reusable and recyclable. Plastic recycling can help in reducing destructive impacts on the environment and help businesses cut costs.
Each plastic container contains a number inside the recycling symbol, called the SPI code, which gives information about the safety and biodegradability of the plastic type. Knowing these codes will help you understand the sorting of recycling materials.
The Importance Of Plastic Recycling
The government organizations or waste management providers have zero waste for landfill policy and regulatory environmentally-friendly disposal methods.
Recycling any material is crucial to the environment, although plastic recycling has unique advantages. Plastics take several years to biodegrade to many varieties, which means it causes landfills to pollute the setting for a long. In addition, recycling plastics can save limited natural resources and energy. The plastic material made from oil and hence conservation of plastic by recycling will help in oil conservation.
Plastics are not suitable for all environmentally friendly disposal solutions.
For example, not all plastics are widely recyclable, and energy release from combustion is not possible because flammable plastics emit harmful gases.
How is Plastic Recycled?
Firstly plastics are classified based on the resin type they have. classification can be performed by machines or manually. After sorting, we follow two prominent plastic recycling roles: mechanical recycling and chemical recycling, wherein the plastic is washed and melted. Then the plastic is broken down into monomers to grow as a new polymer that gets reused.
The type of plastic that is often recycled are:
● Polyethylene Terephthalate (PET )
● Polyvinyl chloride
● High-Density Poly Ethylene
● Low-Density Poly Ethylene
● PE (polyethylene)
● ABS (Acrylonitrile butadiene styrene)
● PS (Poly Styrene)
- Polyethylene Terephthalate – It is a Recyclable plastic (PET)
PET plastic is a common reusable plastic material. It is usually used in single-use water bottles.
PET can be reused for fillings of polyester fabrics and wool, carpets, and cushions.
2. High-Density Polyethylene – It is a Recyclable plastic (HDPE)
HDPE is often found in stiff-colored bottles and can be recycled.
HDPE can be recycled as detergent bottles and pens.
3. Polyvinyl Chloride – It is a Recyclable Plastic (PVC)
PVC has a long history of recycling and has an advanced recycling system
You can find this plastic in Platic pipes, blister packaging, hoses, table protectors, cling film, plastic outdoor furniture
4. Low-Density Polyethylene – It is a Recyclable plastic (LDPE)
LDPE is a complex and flexible material that tends to have a feature of recyclability.
LDPE material can get recycled into dustbin covers/bags or liners.
The most common is the landfill. However, plastic waste can usually be reused, which means that plastic will transfer it from the landfill within a period. That is, plastic bags can be reused many times before disposal.
Alternatives to landfills must be explored, and plastic waste should not be immediately regarded as useless but as valuable.
