Introduction
Overview of Global Packaging Waste
Packaging waste is a growing global concern, with increasing amounts of packaging material being generated every year. The rapid rise in e-commerce, food delivery services, and consumer goods packaging has contributed to a surge in packaging waste. In 2023 alone, the European Union (EU) generated a total of 79.7 million tonnes of packaging waste, while California faced a significant challenge with 8.5 million tonnes of single-use packaging waste going to landfills.
Importance of Plastic Recycling
Recycling is vital to managing the ever-growing volume of packaging waste. As plastic continues to dominate the packaging sector, its environmental impact has been widely scrutinized. The focus has been on developing recycling systems that can effectively process plastic packaging, especially materials like polyethylene terephthalate (PET) and recycled PET (RPET), which are central to the food packaging industry.
Focus on PET and RPET in Food Packaging
PET is one of the most commonly used materials in food packaging, known for its strength, transparency, and recyclability. RPET, which is made from post-consumer recycled PET, has gained attention for its role in the circular economy and as an eco-friendly alternative to virgin plastic. This blog will explore the current recycling rates for PET and RPET, the challenges faced in recycling these materials, and their role in sustainable food packaging.
Global Packaging Waste Data (EU and California)
EU Packaging Waste Data (2023)
The European Union’s packaging waste statistics for 2023, released by Eurostat, show that the EU generated 79.7 million tonnes of packaging waste in total, which equals 177.8 kg per person. This represents a slight decrease of 4.7% compared to 2022, which is promising, but there is still much work to be done in improving recycling rates.

PET and RPET’s role in food packaging is crucial, as these materials are transparent, lightweight, durable, and suitable for direct food contact, making them ideal for packaging liquids, ready-to-eat meals, and fresh produce. Despite their recyclability, the challenge lies in improving the collection, sorting, and processing of plastic packaging, especially when it is contaminated with food residues.
Plastic Packaging in California
In California, plastic packaging waste has also been a significant contributor to landfills. The state’s focus on recycling has seen some progress, but the figures show that much work remains to divert plastic packaging waste from landfills.
PET and RPET’s contribution to California’s packaging waste is significant, as many food and beverage products in the state are packaged in PET bottles, trays, and cups. However, California’s recycling rates for plastic have been slower than expected, and the state faces challenges in enhancing its infrastructure to process these materials.
Recycling Challenges for Plastic Packaging
Recycling plastic packaging, particularly PET, faces a variety of challenges, including contamination from food waste, lack of consumer participation in sorting, and insufficient infrastructure for processing recycled materials. A major issue is downcycling, where recycled plastics are often converted into lower-quality products, such as textiles or construction materials, instead of being reused for food-grade packaging.
PET and RPET in Food Packaging: Role and Impact
PET in Food Packaging
PET is a popular choice for food packaging due to its lightweight, strength, and clarity. It is commonly used for bottles, trays, containers, and cups. PET’s recyclability is one of its greatest advantages, but it faces challenges in being recycled back into the same high-quality material used in food packaging.
Recycling Rates in the EU and California
The EU has made progress in PET recycling, but still falls short of its 55% recycling target for plastic by 2030. PET recycling in California is similarly challenging, as the state’s recycling systems have struggled to keep up with the growing demand for recycled materials.
RPET in Food Packaging
RPET is made from recycled PET products and is increasingly used in the food industry as a sustainable alternative to virgin PET. RPET has the advantage of reducing the need for new plastic production, conserving resources, and lowering carbon emissions.
RPET’s Role in Circular Economy
The use of RPET in food packaging contributes to the circular economy by reusing materials that would otherwise end up in landfills. By recycling PET into RPET, the food packaging industry can reduce its environmental footprint and help meet sustainability targets.
Comparison of PET vs. RPET Recycling Rates
| Region | PET Recycling Rate (%) | RPET Recycling Rate (%) |
|---|---|---|
| EU | 43.7% | 37.1% |
| California | 41.0% | 35.0% |
Source: Eurostat, 2023 & CalRecycle, 2025
RPET has a slightly better recycling rate than PET due to its focus on post-consumer plastic. However, RPET still faces challenges in being recycled back into food-grade material. Overcoming these challenges is critical for improving the overall sustainability of plastic packaging in the food industry.
Recycling Challenges and Downcycling
Challenges in Plastic Packaging Recycling
Recycling plastic packaging faces significant challenges, including the following:
-
Contamination: Food residues and other contaminants make plastic harder to recycle.
-
Lack of Collection Infrastructure: Many regions still lack the necessary systems for collecting and sorting recyclable materials.
-
Technological Limitations: Not all plastic can be recycled into the same quality material due to limitations in sorting and processing technology.
Downcycling: The Fate of Non-PET Packaging
Downcycling occurs when plastic materials are recycled into lower-quality products, such as clothing or construction materials. This process limits the potential for closed-loop recycling and the use of plastic packaging in the same applications. As a result, materials like PLA, PP, and PS often face downcycling rather than being recycled into food-grade materials.
Current and Future Trends
Sustainability Trends in Food Packaging
As the demand for sustainable packaging grows, the food industry is increasingly turning to alternative materials, including biodegradable plastics, paper-based packaging, and compostable materials. However, PET and RPET continue to dominate due to their excellent properties and recyclability.
Global Recycling Regulations and Targets
Both the EU and California have set ambitious recycling targets. By 2030, the EU aims to recycle 70% of packaging waste, with specific targets for different materials. California has also introduced extended producer responsibility (EPR) laws, requiring manufacturers to take responsibility for the recycling of their packaging materials.
