Understanding the challenge: The need for a circular economy

In the world of materials science, the structure of a material is key to its function. The growing demand for new products generates a growing demand for new materials with improved sustainable properties that can withstand everyday applications at a commercial scale.

Over the last 50 years, global mineral extraction and waste production have skyrocketed1, causing multiple environmental crises. “Circular economy” thinking can help alleviate these crises by replacing “take-make-waste” patterns with an approach that keeps resources in a closed loop of use and reuse.

Genuine sustainability, however, involves more than minimising material inputs and outputs. For example, imagine a technology that could endlessly recycle a piece of packaging without any material losses. One might think that this would be in accordance with circular economy principles, and thus be regarded as sustainable. This hypothetical method may, though, have high energy demands, or perhaps it would require packaging to be transported to a distant processing centre. As a result, there would be inputs (energy, and the material used to create that energy) and outputs (pollution from energy use and transport) that would undermine its sustainability.

With this in mind, there are three areas where attention is required to ensure that materials and design are sustainable and aligned with a circular economy for packaging.

Three areas where focus is needed

Minimise resource extraction

Reducing the impact of the resources used to create packaging pushes it towards circularity and sustainability. Different material inputs have substantially different impacts: Fossil-based plastics take millions of years to form; plant-based materials, perhaps only a few years.

Minimise waste

Keep material in the circular economy through recycling. Doing so alleviates the need to extract more resources and reduces the environmental and social consequences of waste and pollution.

Resource efficiency

It’s important that any resources used to keep material within the circular economy – energy and water, for example – are not excessive. Resource efficiency needs to be ensured in any work that’s done to keep materials in the system.

Questions that matter for a growing population

The world’s population is growing faster than ever, and to make sure we can continue to feed the planet – in a safer, more sustainable and more equitable way – it takes many voices and bright minds.

 

This short video highlights a few of the questions that our experts and those we collaborate with are asking to find tomorrow’s solutions.

The ultimate package

We are working towards the world’s most sustainable food package2. Find out exactly what that means in a conversation with Tetra Pak and paperboard manufacturer BillerudKorsnäs.

A better barrier for food and beverage packaging

Plastic has been a very effective barrier in food packaging, but it’s now time to start reducing fossil-based layers and, eventually, replacing them with fibre – while keeping food safe.

Responding to demands for less plastic

Consumers want less plastic in their packaging, and a greater percentage of fibre material is one answer.

Reducing waste

Keeping food waste to a minimum reduces the impacts of food production on our environment, makes more food available for everyone, and lowers costs for producers and consumers alike.

Food production

Enzymes, enrichment and even insects. These and many more innovative solutions will be needed to address global food production challenges that include an estimated 70% increase in the need for animal proteins by 2050.

This means creating cartons that are fully made of renewable or recycled materials, that are responsibly sourced, therefore helping protect and restore our planet's climate, resources and biodiversity; contributing towards carbon-neutral production and distribution; are convenient and safe, therefore helping to enable a resilient food system; are fully recyclable.
