Plastic production heavily relies on finite natural resources such as petroleum, natural gas, and coal. By recycling plastic waste, we can significantly reduce the demand for these resources and conserve them for future generations. In fact, recycling discarded and old plastic waste can lead to a remarkable 40% reduction in petroleum consumption. Furthermore, manufacturing new plastic products from recycled materials requires substantially less energy compared to producing them from raw materials. According to a study from Stanford University, recycling one ton of plastic can save 7,200 kilowatt-hours of electricity, which is enough to power an average household for seven months.

Lowering Greenhouse Gas Emissions

The manufacturing of plastics is a significant contributor to greenhouse gas emissions, which are a leading cause of climate change. By recycling plastic, we can help reduce the emission of these hazardous gases and combat global warming. Recycling plastic not only decreases the need for new plastic production but also lowers the carbon footprint associated with the extraction, transportation, and processing of raw materials. In fact, GCC countries alone could cut CO2 emissions by about 2 to 2.5 percent of the expected emissions from the building materials sector by 2040 simply by substituting recycled plastics in construction.

Plastic recycling not only benefits the environment but also stimulates economic growth. By substituting recycled plastics, we can encourage innovation, create up to 13,000 jobs, and boost GDP by some US$2 billion to $3 billion by 2040.

Moreover, plastic recycling plays a crucial role in reducing pollution and protecting wildlife. Plastic litter is a major threat to animal species, particularly in marine ecosystems where it can be ingested or entangle marine life. By keeping plastic waste out of the environment through recycling, we can help preserve biodiversity and maintain the delicate balance of our ecosystems.

The Plastic Recycling Process

The plastic recycling process is a multi-step approach that transforms discarded plastic waste into new, usable materials. This process is crucial in reducing the environmental impact of plastic pollution, as it helps conserve natural resources, decrease greenhouse gas emissions, and minimize the amount of waste sent to landfills. With only 9% of the 6.3 billion metric tons of plastic waste produced over the past 70 years being recycled, it is essential to understand and optimize the plastic recycling process.

Collection and Sorting

The first stage of the plastic recycling process involves the collection of plastic waste from various sources, including homes, businesses, schools, and other collection sites. Once collected, the plastic waste undergoes sorting to separate different types of plastics based on their chemical composition and recycling potential. This sorting process is crucial as mixing non-recyclable plastics with recyclable ones or attempting to recycle soiled plastics can lead to contamination issues, compromising the quality of the recycled material.

Sorting techniques at Material Recovery Facilities (MRF) include:

• Manual picking
• OCC screening
• Ballistic separation
• Magnet separation
• Eddy currents
• Optic sorting
• Sink-float separation

Cleaning and Shredding

After sorting, the plastics undergo a thorough cleaning process to remove contaminants such as adhesives, residual waste, food waste, and labels. These contaminants can significantly impact the quality of the recycled material if not removed. Once cleaned, the plastics are shredded or ground into smaller pieces using machines like Hammer Mills and Shear Shredders. This step is critical as it increases the surface area of the plastic, making it easier to melt and reform into new products.

Melting and Reforming

The final stage of the plastic recycling process involves melting the shredded plastic and extruding it through a machine to form new pellets or flakes. These recycled materials can then be sold to manufacturers to create a wide range of products, including packaging materials, textiles, furniture, and even new plastic bottles. It is important to note that plastics are not infinitely recyclable; with each processing cycle, the material degrades in quality.

As recycling rates for plastics continue to increase and innovations such as chemical recycling emerge, the plastic recycling process is expected to improve further.
