We Need Sustainable Food Packaging Now.
Every day, hundreds of millions of single-use containers, cans, trays, and cutlery are thrown away around the world. While packaging is an essential component of the food sector and the only solution we have to facilitate food transportation, food packaging waste is also one of the most harmful aspects of this industry. We outline the advantages and disadvantages of the most popular materials used to wrap groceries and takeaway foods and explore innovative sustainable food packaging that could revolutionise the market and protect the environment.

In ancient history, humans used to consume food from where it was found. There were no grocery shops, takeaway and delivery services, and almost no imports and exports of food on a global scale. But things changed rapidly in the 20th century. Suddenly, countries began shipping produce from one end of the world to the other; supermarkets in the US started selling Southeast Asian tropical fruits; China depended on Brazil for its soybean supplies; and European countries were importing coffee from Africa. The emergence and subsequent surge in international shipping of food staples led to a revolution in the packaging sector.
Since food needed to travel long distances to keep up with global demand, it became crucial to find ways to ensure food remained fresh and undamaged at the time of consumption. Packaging turned out to be the best way to extend food shelf-life as it retarded product deterioration, retained the beneficial effects, and maintained the nutritional values, characteristics, and appearance of foods for longer times.
Materials that have been traditionally used in food packaging include glass, metals (aluminium, foils and laminates, tinplate, and tin-free steel), paper, and paperboards. Plastic, by far the most common material used in food packaging today, is also the newest option. Since the plastic boom in the early 1980s, new varieties of this material have been introduced in both rigid and flexible forms, slowly replacing traditional materials due to their versatility, easy manufacturing process, and cheap price. Of all plastics produced worldwide today, nearly 40% are used for food and drink packaging.
But food retailers are not the only industry that contributed to the rapid acceleration in plastic and packaging production. Consumer habits changed drastically within the restaurant industry too. The first takeaway options were already available in the 1920s, but it was not until after World War II that consumers started appreciating the convenience of drive-throughs and other take-home options. In America, fast food chains such as In-N-Out Burger and McDonald’s were responsible for the industry’s boom and with the expansion of the transportation industry, delivery options also began expanding around the world. This inevitably led to a massive influx of food packaging solutions that allowed consumers to pick up pre-cooked dishes and consume them elsewhere.
Most of the containers that we have today are single-use, non-compostable, and difficult to degrade because of food contamination. Both the restaurant and retail industries are major contributors of food packaging waste. Finding a balance between food protection and environmental consciousness undoubtedly requires huge efforts. Given the increasing consumer (and manufacturer) awareness of the environmental and health impacts of non-degradable packaging, in recent years the packaging industry has been seriously looking at alternative, more environmentally friendly materials as well as ways to reduce packaging where it is not absolutely necessary. Restaurants, in particular, have seen sustainable packaging options widely expanded to include compostable and recyclable packaging. According to Globe News Wire, the biodegradable packaging market will reach a value of USD$126.85 billion by 2026.
