Continua após a publicidade..

Coffee is one of the most popular beverages in the world, with billions of cups consumed every day. However, coffee production and consumption also have a significant environmental impact, especially when it comes to packaging.

Traditional coffee packaging materials, such as aluminum and plastic, are not only derived from fossil fuels, but also generate a lot of waste and greenhouse gas emissions.

In this article, we will explore how bioplastics, a type of eco-friendly packaging material, can offer a more sustainable solution for coffee packaging. We will also discuss the innovations, benefits, challenges and future prospects of using bioplastics in coffee packaging.

Understanding Bioplastics: Eco-Friendly Coffee Packaging

Bioplastics are plastics that are either bio-based, biodegradable or both. Bio-based plastics are made from renewable sources, such as plants, algae or waste. Biodegradable plastics are plastics that can be broken down by microorganisms into natural substances, such as water, carbon dioxide and biomass. Some bioplastics are both bio-based and biodegradable, while others are only one or the other.

Bioplastics can be used for various applications, including food and beverage packaging. Bioplastics can offer several advantages over conventional plastics for coffee packaging, such as:

  • Reducing the dependency on fossil fuels and the associated greenhouse gas emissions.
  • Preserving the quality and freshness of coffee by providing adequate barrier properties against oxygen, moisture and light.
  • Enhancing the aesthetic appeal and brand image of coffee products by offering a variety of colors, shapes and designs.
  • Supporting the circular economy by enabling the recovery and reuse of valuable resources from waste streams.

The Environmental Impact of Traditional Coffee Packaging

Traditional coffee packaging materials, such as aluminum and plastic, have a high environmental impact throughout their life cycle. According to a study by the University of Manchester, aluminum capsules have the highest carbon footprint among different coffee packaging formats, followed by plastic capsules and plastic bags. The study estimated that in 2018, the global consumption of coffee capsules generated about 180,000 tonnes of aluminum waste and 40,000 tonnes of plastic waste.

Another study by the University of Bath found that aluminum capsules require up to 20 times more energy to produce than plastic ones, and emit up to 14 times more greenhouse gases. The study also found that only about 21% of aluminum capsules and 28% of plastic capsules are recycled globally. The rest end up in landfills or incinerators, where they release toxic substances and contribute to climate change.

Moreover, traditional coffee packaging materials do not account for the organic content of coffee, which makes up about 80% of the weight of a coffee capsule. The organic content of coffee is a valuable resource that can be used as a soil amendment or a source of energy.

However, when mixed with conventional plastics or aluminum, it becomes difficult to separate and recover the organic content from the packaging material. As a result, the organic content is lost or wasted in other end-of-life options.

Bioplastics in Coffee Packaging: Innovations and Benefits

Bioplastics can offer a more sustainable alternative to traditional coffee packaging materials by reducing the environmental impact and enhancing the value retention of coffee products.

Bioplastics can be used for different types of coffee packaging formats, such as capsules, pods, bags or sachets.

Some examples of bioplastics used for coffee packaging are:

Polylactic acid (PLA): PLA is a bio-based and biodegradable plastic that is made from fermented sugars derived from corn or sugarcane. PLA has good barrier properties against oxygen and moisture, which are essential for preserving the quality and flavor of coffee. PLA can also be processed into various shapes and colors to create attractive and functional coffee packaging designs.

Polyhydroxyalkanoates (PHA): PHA is a bio-based and biodegradable plastic that is produced by bacterial fermentation of organic waste or vegetable oils. PHA has excellent mechanical properties and biocompatibility, which make it suitable for food contact applications. PHA can also withstand high temperatures and pressures, which are required for brewing espresso coffee.

Cellulose: Cellulose is a bio-based and biodegradable polymer that is extracted from plant fibers or waste materials, such as wood pulp or coffee grounds. Cellulose has high tensile strength and transparency, which make it ideal for flexible film applications. Cellulose can also be modified to improve its barrier properties against oxygen and moisture.

Bioplastics can provide several benefits for coffee packaging, such as:

  • Reducing the carbon footprint and energy consumption of coffee packaging production by using renewable sources instead of fossil fuels.
  • Improving the recyclability and compostability of coffee packaging by facilitating the separation and recovery of the organic content from the packaging material.
  • Increasing the shelf life and quality of coffee products by providing adequate protection against external factors that can affect the taste and aroma of coffee.
  • Creating new market opportunities and competitive advantages for coffee producers and retailers by meeting the growing consumer demand for eco-friendly and innovative coffee packaging solutions.

Biodegradable and Compostable Coffee Bags

One of the most promising applications of bioplastics in coffee packaging is biodegradable and compostable coffee bags. Biodegradable and compostable coffee bags are coffee bags that can be disposed of in a composting facility or a home compost bin, where they will degrade into natural substances that can enrich the soil. Biodegradable and compostable coffee bags can offer several advantages over conventional coffee bags, such as:

Eliminating the need for additional packaging materials, such as valves, zippers or labels, which can reduce the material and cost efficiency of coffee packaging.

Simplifying the disposal and collection of coffee packaging waste by allowing consumers to dispose of the entire coffee bag, including the coffee grounds, in their organic waste bin.

Supporting the organic recycling of coffee packaging waste by ensuring that the coffee bag and its contents are compatible with the composting process and do not contaminate the compost with non-compostable plastics or metals.

Promoting the circular economy by enabling the reuse of valuable resources from coffee packaging waste, such as nutrients, organic matter and energy.

According to a report by European Bioplastics, more than 100 different types of coffee capsules are already certified as industrially compostable, in line with EN 13432, by independent certification schemes.

The report also states that compostable coffee capsules are a preferred option from a life-cycle assessment point of view, as they significantly increase the capture of biowaste, reduce the contamination of compost with non-compostable plastics, and do not lead to increased contamination of other waste streams.

Some examples of coffee companies that have switched to bioplastics for their coffee packaging are:

Lavazza: Lavazza is an Italian coffee company that has launched a range of compostable coffee capsules made from PLA. The capsules are compatible with Lavazza’s own machines and can be disposed of in the organic waste bin. Lavazza claims that its compostable capsules have a 60% lower carbon footprint than its conventional plastic ones.

Nespresso: Nespresso is a Swiss coffee company that has introduced a collection of bio-based and compostable coffee pods made from PHA. The pods are compatible with Nespresso’s original machines and can be composted at home or in an industrial facility. Nespresso states that its bio-based pods have a 40% lower environmental impact than its aluminum ones.

Taylors of Harrogate: Taylors of Harrogate is a British tea and coffee company that has developed a fully compostable coffee bag made from cellulose and PLA. The bag can be brewed like a tea bag and can be disposed of in a home compost bin or a food waste bin. Taylors of Harrogate says that its compostable bag is a world first and a breakthrough innovation for the coffee industry.
