It is estimated that nearly 60% of the total plastics manufactured globally are dedicated to food packaging. This statistic highlights a staggering figure: out of the 380 million metric tons of plastics produced in 2015, a significant 228 million metric tons were utilized solely for packaging food items. The alarming environmental and health repercussions associated with non-biodegradable plastic packaging have prompted a surge in advocacy for a substantial reduction in plastic production, alongside efforts to enhance recycling practices and promote more sustainable alternatives for food packaging.

This article delves into the critical necessity for eco-friendly food packaging, explores five innovative types to consider integrating into your lifestyle, and identifies several types of packaging that are best avoided.

Why is Sustainable Food Packaging Vital?

The growing concerns regarding plastics encompass their persistent accumulation in our oceans and landfills, the emergence of micro- and nanoplastics, and the potential for human exposure to harmful toxins when chemicals from food packaging leach into the food supply. This issue is critical as it not only affects marine life but also poses risks to human health. Moreover, food packaging often contains numerous substances that are not intentionally added (NIAS), presenting toxicity and endocrine-disrupting threats to humans. These hidden chemicals can have significant adverse effects, emphasizing the need for safer alternatives.

Fortunately, sustainable and environmentally friendly packaging options are becoming increasingly popular. These innovative solutions frequently utilize biodegradable bioplastics and plant-derived materials such as wheat, wood, and bamboo, which are designed to be reusable and devoid of hazardous chemicals.

Although studies indicate that these eco-friendly packages may still contain chemicals and NIAS, the research shows that the transfer of these substances into food and, subsequently, into our bodies is significantly lower compared to conventional plastics. This makes them a safer choice for both human health and the environment. While complete avoidance of chemical exposure from food packaging is nearly impossible, it is essential to minimize the transfer of these substances into our food items to safeguard human health. The dangers posed by plastic food packaging are extensive, including their contribution to ocean pollution and potential disruption of the endocrine system. Fortunately, the rise of eco-friendly alternatives offers hope for a safer future.

Sustainable Food Packaging Alternatives

Explore these 5 eco-conscious food packaging options that not only benefit the environment but also promote your health.

1. Glass Containers

Glass is an incredibly versatile material that offers numerous advantages for everyday use. Being reusable, recyclable, and incredibly durable, glass makes for an ideal choice in transportable food packaging. Common glass containers include water bottles and bento boxes. However, it's important to note that glass lids are not completely leak-proof, which can limit their suitability for carrying meals to work, school, or other outings. To address this, many portable glass food containers feature snap-lock plastic lids equipped with a silicone seal or bamboo lids that can double as handy cutting boards. Make sure to opt for lids free from bisphenol-A (BPA), as this chemical is a recognized endocrine disruptor linked to fertility issues and tumor growth. These glass containers can last approximately 3.5 times longer than their plastic counterparts and are recyclable, thereby diminishing the adverse environmental effects of plastic waste.

5. Gelatin Films

Gelatin films are gaining traction as a sustainable food packaging solution due to their nontoxic nature, affordability, and effective film-forming abilities. According to the Food and Drug Administration (FDA), gelatin is widely recognized as safe (GRAS) as a food additive. These films are infused with antimicrobial cellulose that helps prevent the proliferation of common foodborne pathogens, including Staphylococcus aureus and E. coli. This makes gelatin films a safer choice compared to traditional plastics. Microcrystalline cellulose (MCC) and rosin-grafted cellulose nanocrystals (r-CNCs) are two key additives used in gelatin food packaging. Ultimately, glass containers, food-grade stainless steel, bamboo, rice husk, and cellulose-based gelatin films represent some of the most environmentally friendly food packaging options available today.

Types of Plastics You Should Steer Clear Of

Conventional plastics are often laden with various additives including stabilizers, fillers, plasticizers, flame retardants, and increasingly, antimicrobials. These products, derived from petroleum, lack the ability to biodegrade, which means they do not break down into harmless natural substances. Instead, they disintegrate into smaller particles known as microplastics and nanoplastics, which pose a serious threat to our environment and endanger both natural ecosystems and human health. Although these additives might enhance the functionality of plastic for food storage and transportation, they also contribute to environmental pollution and elevate the risk of endocrine disruptors and various cancers among humans.

Let's examine three types of petroleum-based plastics that you should avoid at all costs.

1. Single-Use Plastics

Common examples of single-use plastics include straws, beverage bottles, bottle caps, polystyrene cups, and plastic bags, all of which are notoriously unsustainable and often disposed of irresponsibly. Oceans and coastal regions are particularly vulnerable to the adverse effects of single-use plastics, a situation highlighted by the Great Pacific Garbage Patch, an enormous collection of plastic debris located in the Pacific Ocean between Japan and Hawaii.

2. Plastics Containing BPA

Bisphenol-A (BPA) is a plasticizing agent commonly used in the production of polyvinyl chloride (PVC), which is found in numerous plastic items. Not only does BPA accumulate in the environment, but it also migrates from food packaging into the food itself. When consumed, BPA may heighten your risk of infertility, polycystic ovary syndrome (PCOS), and various metabolic disorders.

3. Disposable Takeout Containers

The prevalent use of single-use takeout containers significantly contributes to waste generation, leading to pollution and environmental toxins. It is advisable to actively avoid, and advocate for the reduction of, single-use plastics, BPA-laden packaging, and disposable containers due to their detrimental impacts on both the environment and public health.

Effective Strategies to Minimize Plastic Packaging Usage

• Consider replacing single-use plastic straws with durable options like reusable metal or bamboo straws. For optimal hygiene, don't forget to include cleaning brushes specifically designed for these straws. If you prefer a disposable option, paper straws are an excellent biodegradable alternative.
• When it comes to hydration, select nonplastic or BPA-free reusable water bottles. Investing in a bottle brush can also enhance cleanliness and longevity.
• Utilizing at-home water filtration systems, whether they are faucet filters or pitcher filters, significantly decreases the reliance on single-use plastic water bottles, promoting sustainability.
