Plastic, or to be more precise, PET bottles are some of the most common waste materials that we see around us in our everyday life. Plastic is a non-degradable material that never decomposes, causing a serious threat to the serenity and safety of the environment. Reusing it remains the only possible solution to save the atmosphere.
The below subsections highlight stepwise procedures of PET bottle recycling –
PET Waste – Consumers buy beverages in PET bottles, which they discard after use. Those empty, discarded bottles, then become PET waste, or if we go by the industry terms, post-consumer waste. Government agencies and NGOs will collect the waste from the collection points, and supply it to recycling plants, where it will be taken through intense recycling procedures.
Categorization of the waste based on its condition – Not necessarily recycling plants or Materials Recovery Facilities (MRFs) receive same or good quality PET waste. In this leg, received waste materials are sorted and identified for further reprocessing. For the effective recycling of PET, it is important to send only the appropriate PET scrap into the recycling machines. Different materials are sorted, labeled, and stored separately in this stage.
Compaction and Baling – After sorting, plastic waste is compacted with PET bottle compactor, and turned into bales, which are sold and sent to hardcore recycling companies.
Additional Procedures – At a recycling plant, apart from being crushed, waste also has to be washed and dried, so that quality in the recycled products can be ensured. Sometimes, PET waste is melted with specific machines to remove impurities, if any. However, it is done only when the waste has to be used for the manufacturing of beverage bottles.
