“…3 In 1990, less than 2% of eight major commodity polymers were recycled, the rest being landÐlled or incinerated. 4 Recent Ðgures show that 80% of waste goes to landÐll, 10% is recycled and 10% is incinerated. 5 Many governments have identiÐed the plastic waste problem as an area to be carefully controlled.…”

“…Taking into account the markets available for recycled plastic materials it has been estimated that material recycling rates can increase no higher than between 15 and 20% of total waste generated. 4,8,9 Therefore if government targets are to be met, more mixed, and possibly contaminated, plastic will have to be dealt with. Current technology for secondary recycling would Ðnd it difficult to produce a product with enough added value for the materials market.…”

“…This is deÐned as the recovery of monomers or oil from waste plastic by a depolymerisation process. 4 Pyrolysis is such a tertiary recycling process. The polymer sample is heated in an inert atmosphere causing the carbonÈcarbon bonds to break along the polymer backbone.…”

: Six thermoplastics, which represent more than two-thirds of all polymer production in western Europe, were pyrolysed in a static batch reactor in a nitrogen atmosphere. These were high density polyethylene (HDPE), low density polyethylene (LDPE), polystyrene (PS), polypropylene (PP), polyethylene terephthalate (PET) and polyvinyl chloride (PVC). The heating rate used was 25¡C min~1 to a Ðnal temperature of 700¡C. These six plastics were then mixed together to simulate the plastic fraction of municipal solid waste found in Europe. The e †ect of mixing on the product yield and composition was examined. The results showed that the polymers studied did not react independently, but some interaction between samples was observed. The product yield for the mixture of plastics at 700¡C was 9É63% gas, 75É11% oil, 2É87% char and 2É31%

“…As such, there has been a steady increase in the collection and recycling of PET bottles into PCR. PET recycling technology has been widely implemented and advanced for more than five decades [13][14][15]. These advancements continue with improved methods of recovery and conversion into PCR pellets.…”

Polyethylene Terephthalate (PET) Bottle-to-Bottle Recycling for the Beverage Industry: A Review

et al. 2022

Disposal of plastic waste has become a widely discussed issue, due to the potential environmental impact of improper waste disposal. Polyethylene terephthalate (PET) packaging accounted for 44.7% of single-serve beverage packaging in the US in 2021, and 12% of global solid waste. A strategic solution is needed to manage plastic packaging solid waste. Major beverage manufacturers have pledged to reduce their environmental footprint by taking steps towards a sustainable future. The PET bottle has several properties that make it an environmentally friendly choice. The PET bottle has good barrier properties as its single-layer, mono-material composition allows it to be more easily recycled. Compared to glass, the PET bottle is lightweight and has a lower carbon footprint in production and transportation. With modern advancements to decontamination processes in the recycling of post-consumer recycled PET (rPET or PCR), it has become a safe material for reuse as beverage packaging. It has been 30 years since the FDA first began certifying PCR PET production processes as compliant for production of food contact PCR PET, for application within the United States. This article provides an overview of PET bottle-to-bottle recycling and guidance for beverage manufacturers looking to advance goals for sustainability.

Waste generation including plastics continues to increase, aided by the strong economic climate in the 1990s. In the United States, plastics contribute about 10 wt% of the total 230 million tons of waste generated. Most waste comes from municipal solid waste; other sources include autos, appliances, electrical and electronic components, and demolition and construction activities. Although millions of tons are landfilled annually, that is no longer considered a cheap or acceptable form of disposal. Plastic recycling issues are complex. Important aspects include the environmental impact of growing natural resource consumption, the need to revise collection and reprocessing infrastructures, the relatively new “eco‐design” approach to products, and life cycle analysis of “cradle‐to‐grave” use. This article reviews the state of worldwide plastics recycling, the challenges facing this industry in the new millennium, and emerging technologies for addressing these issues.
