Food packaging shakeup needed

Compostable and edible packaging could help remedy plastics crisis

Within a year, single-use plastics and excess packaging have become public enemy No. 1. Everyone is talking about how our lives are overrun by too much plastic.

Just recently, a Greenpeace-led audit looked at waterways waste and the companies involved. Much of the plastic trash cleaned up from Canadian shorelines this fall was traceable to five companies: Nestlé, Tim Hortons, PepsiCo, the Coca-Cola Company and McDonald’s. All these companies are part of the food industry, hardly surprising.

As consumers look for convenience, and more portable food solutions, this problem will not go away any time soon. In fact, it could get worse if nothing is done. The number of meals in Canada consumed outside the home is only increasing.

Canadian households spend roughly 35 per cent of their food budget outside a grocery store, and that percentage is increasing every year. People walking around with plastic containers and bags, wrappers and cups, will grossly increase, and the food service, retail and processing sectors are all fully aware of this environmental conundrum.

Demographics are also complicating things. As more people are living alone, single servings will become more popular. That, too, requires more packaging. What is brutally unclear for companies is how to deal with it. But making the issue of plastic use a political one is creating some movement, everywhere around the world.

In the food industry, the conversation on green supply chains focuses on compostable and even edible solutions. Plenty of technologies exist. On the compostable front, we’ve come a long way in just a few years. In 2010, PepsiCo Canada came out with the first compostable bag of chips for its SunChips product. It was just a disaster. The company pulled it from the market less than a year after its introduction.

Since then, cities, which play a key role in completing any food product’s entire life cycle, have been more reluctant to accept anything without proper due diligence. We are now seeing an increasing amount of compostable packaging on the market, surely a step in the right direction.

But edible packaging seems to also be gaining some currency. Imagine one day walking into a grocery store and everything you see on store shelves can be eaten.

Research has come a long way, but it has not been easy. The first generation of edible packaging was made from starch, which often failed to keep food fresh. But the United States Department of Agriculture (USDA) has been working on a new generation that may get the attention of food industry pundits.

Casein-based food packaging, made from milk proteins, isn’t just edible, it’s also more efficient than other types of packaging, as it keeps oxygen away from the food for an extended period. What is even more interesting is that the edible fabric itself can be infused with vitamins and probiotics to make the product more nutritious. This technology from the agency should be ready in 2019.

These are promising technologies, but no business model has yet been developed, and we still don’t know how the use of edible packaging will affect price points at retail. This is certainly of great concern to retailers

and restaurants. The concept of reducing plastic waste by eating more packaging is intriguing, but not every consumer would think of such a concept as appetizing.

A case has to be made for consumers to eat their garbage. Logistics are certainly an issue with edible packaging. Throughout the supply chain, temperatures tend to vary greatly, which makes it challenging for any edible packaging to preserve the integrity of products, which can travel thousands of kilometres around the world.

Startups looking at this issue are rampant though. According to Transparency Market Research (TMR), a global research firm, demand for edible packaging could increase on average by 6.9 per cent yearly until 2024 and could become a market worth almost $2 billion worldwide. As consumers, we will be given an opportunity to save the planet as we eat our food, and packaging.

In the meantime, Greenpeace can continue to blame companies for the rubbish we find in oceans and waterways, but we are all responsible for this mess. If we want more compostable or edible packages, we may be asked to pay more for our food, to pay a so-called “planet premium,” once these new technologies come around. Regardless, it may be worth it.
