The Challenge of Plastic Waste in Food Packaging

Plastic pollution has emerged as a pressing environmental concern worldwide. According to a report from the United Nations, a staggering 46% of plastic waste ends up in landfills, while an additional 22% is improperly discarded, leading to litter in natural spaces. Unlike many other materials, plastic is not biodegradable and can persist in the environment for up to 1,000 years. This persistence results in significant adverse effects, including harm to marine life, soil degradation, groundwater contamination, and potential health risks to humans. A focused effort on eliminating unnecessary plastic packaging could be a crucial step in mitigating this issue.

A recent study by the paper packaging company DS Smith reveals that over half, approximately 51%, of grocery packaging in the UK could either be reduced or entirely replaced with alternative materials.

This conclusion stemmed from a comprehensive field analysis that evaluated plastic usage across 1,500 food and beverage items from the top five food retailers in six European nations: France, Germany, Italy, Spain, Poland, and the UK.

The methodology employed was a “basket analysis,” which assessed the percentage of items containing plastic packaging in a typical grocery shopping basket. Researchers selected 50 common household items frequently purchased across the surveyed markets. Additionally, they performed a “store inventory analysis” to analyze plastic packaging prevalence in various food and beverage categories within grocery stores. This extensive data collection allowed them to create a plastic packaging index, quantifying plastic usage in both the shopping baskets and product ranges offered in stores.

Upon analyzing the results, the researchers discovered that a significant portion of the plastic packaging within an average grocery basket originated from processed foods, including ready-to-eat meals (90%), bread, rice, and cereals (89%), dairy products (83%), and meat and fish (80%).

The findings also highlighted that the UK stands out as the country with the highest reliance on plastic packaging, with 70% of food and drink products on its shelves containing plastic. Following closely behind were Spain at 67%, and both Italy and Germany at 66%. Poland and France had slightly lower figures, at 62% and 59%, respectively.

In addition to the field study, the researchers conducted a survey in June 2024 with 300 senior professionals from the food and drink sector, focusing on packaging. Their responses indicated that an overwhelming 98% of companies are committed to decreasing their use of plastic packaging. However, many face hurdles, with 60% of respondents striving to meet voluntary targets within two years. Cost concerns for raw materials emerged as the primary challenge for 40% of those surveyed, alongside the worry that consumers may resist such changes. Notably, 72% of respondents expressed concern that consumers would be hesitant to pay more for sustainable packaging, and nearly two-thirds believed customers prefer convenience to sustainability.

These apprehensions regarding consumer sentiment may not fully reflect market trends. A 2023 study from the Harvard Business Review found that when younger consumers, particularly Gen Z and Millennials, perceive a brand’s commitment to social and environmental responsibility, they are 27% more likely to make a purchase compared to older consumers. This shift in purchasing power, projected to reach up to $68 trillion by 2030 as wealth transfers from Baby Boomers to younger generations, underscores the significance of sustainable marketing strategies aimed at these demographics.

As Miles Roberts, the CEO of DS Smith, emphasized in a conversation with Materials Recycling World, the push for reduced environmental impact is essential. He advocated for stronger governmental regulations on plastic usage to foster innovation and competition in developing sustainable packaging alternatives. “We think the Government can and should be more demanding of us all,” he stated, highlighting the need for collaborative efforts to transition away from plastic.
