• Usage: The consumer's interaction with the packaged beverage.
• End-of-Life: Disposal methods, including recycling, landfilling, or incineration.

Each stage contributes uniquely to the overall environmental impact, influenced by the material type and packaging design.

Coffee Cups: Disposable vs. Reusable Options

Disposable Coffee Cups

Single-use coffee cups, predominantly made of paper lined with plastic, are ubiquitous in cafes worldwide. Despite their convenience, they pose significant environmental challenges.

• Production: Manufacturing these cups involves substantial energy and water consumption. The plastic lining, typically polyethylene, complicates recycling efforts, leading to a low recycling rate.

• Carbon Footprint: A single-use paper cup's carbon footprint is approximately 16 grams of CO?. Considering the billions of cups discarded annually, the cumulative environmental impact is considerable.

Reusable Coffee Cups

Transitioning to reusable cups offers a sustainable alternative with long-term benefits.

• Materials: Common materials include stainless steel, ceramic, and durable plastics.
• Usage: The environmental advantage of reusable cups becomes evident after multiple uses. For instance, a reusable plastic cup may offset the impact of disposable cups after 10 uses, while a ceramic cup might require up to 50 uses due to the energy-intensive manufacturing process.

Key Takeaway: Consistently using a reusable cup can significantly reduce the environmental footprint of your daily coffee consumption.

Juice Packaging: Cartons vs. Glass and Plastic Bottles

Juice beverages are packaged in various materials, each with distinct environmental implications.

Cartons (e.g., Tetra Pak)

• Composition: Typically composed of paperboard, polyethylene, and aluminum layers.
• Carbon Footprint: Cartons generally exhibit a lower carbon footprint compared to glass and plastic bottles. Their lightweight nature reduces transportation emissions, and sourcing from renewable materials like paperboard further diminishes their environmental impact.

Glass Bottles

• Production: Glass manufacturing is energy-intensive, requiring high temperatures to melt raw materials.
• Carbon Footprint: Single-use glass bottles have a higher carbon footprint due to their weight and the energy consumed during production and transportation.

Plastic Bottles (PET)

• Production: Producing PET bottles involves extracting and processing fossil fuels, contributing to greenhouse gas emissions.
• Carbon Footprint: While lighter than glass, plastic bottles still have a significant carbon footprint. Effective recycling programs can mitigate their environmental impact.

Key Takeaway: Among single-use options, cartons often present a lower carbon footprint for juice packaging. However, the overall impact depends on regional recycling facilities and consumer disposal habits.

Energy Drink Packaging: Aluminium Cans vs. Plastic Bottles

Energy drinks are primarily packaged in aluminium cans, with some available in plastic bottles.

Aluminium Cans

• Production: Aluminium production is energy-intensive but yields a highly recyclable material.
• Carbon Footprint: Despite the energy required for production, aluminium cans often have a lower carbon footprint than plastic bottles, especially in regions with high recycling rates.

Plastic Bottles

• Production and Disposal: Similar to juice packaging, PET plastic bottles for energy drinks contribute to environmental degradation through fossil fuel use and potential pollution if not properly recycled.

Key Takeaway: In areas with robust recycling programs, aluminium cans may offer a more sustainable option for energy drinks compared to plastic bottles.

Milk Packaging: Glass Bottles, Plastic Jugs, and Cartons

Milk is available in various packaging formats, each with unique environmental considerations.

Glass Bottles

• Reusable Systems: In some regions, glass milk bottles are collected, sterilized, and reused multiple times.
• Carbon Footprint: The initial production of glass is energy-intensive, but reusing bottles can offset the environmental impact over time. However, transportation emissions can be higher due to the weight of glass.

Plastic Jugs (HDPE)

• Production: High-density polyethylene (HDPE) production is less energy-intensive than glass manufacturing.
• Carbon Footprint: Plastic jugs are lightweight, reducing transportation emissions. Their environmental impact is lower than single-use glass bottles but depends on effective recycling.

Cartons

• Composition: Similar to juice cartons, milk cartons combine paperboard with plastic and sometimes aluminium.
• Carbon Footprint: Cartons are lightweight and often have a lower carbon footprint than glass and plastic. However, their recyclability varies by region.
