In my journey to operate a truly low-impact studio, I have had to confront some uncomfortable truths about sustainability. One of the most significant realisations involves the materials used to package our hair products. While many of us instinctively feel that glass or aluminium are the “greener” choices, the reality of their carbon footprint tells a much more complex story.
The Carbon Reality of Glass and Aluminium
Glass and aluminium are often celebrated because they are infinitely recyclable, which is a vital part of a circular economy. However, the process of recycling these materials is incredibly energy-intensive.
- The Weight Issue: Glass is heavy. Shipping heavy bottles from a factory to a studio requires significantly more fuel, which leads to higher CO2 emissions during transit.
- The Heat Issue: To recycle glass or aluminium, they must be melted down at extremely high temperatures. This process requires a vast amount of energy, often far more than is required to recycle or even produce high-quality plastic.
Why Plastic is Often the “Lesser Evil”
It is strange and frustrating to admit, but lightweight, high-grade plastic often has a lower carbon footprint than its glass counterparts.
- Efficiency: Because plastic is lightweight, more products can be transported in a single shipment, reducing carbon emissions per bottle.
- Energy Density: Processing plastic requires lower temperatures and less energy compared to the intense heat needed for metal or glass.
Why I Am Still Not Satisfied
Even though the data currently suggests that plastic is often the more carbon-efficient option, I am personally not happy with its presence in the industry. Plastic brings its own set of catastrophic environmental issues:
- The Microplastic Crisis: Plastic eventually breaks down into micro-particles that infiltrate our oceans and food chains.
- Poor Recycling Rates: Despite our best efforts, a huge percentage of plastic still ends up in landfill or the environment due to failings in global waste management.
- Oil Dependency: Most plastic is still a byproduct of the fossil fuel industry, which is something I aim to distance my business from.
Seeking a Third Way
Sustainability is not a destination; it is a constant process of evaluation. This is why I prioritise brands that are actively seeking better alternatives:
- Ocean Waste Plastic (OWP): Brands like KEVIN.MUPHY use plastic that has been recovered from the ocean, helping to clean up existing pollution while keeping carbon emissions low.
- Post-Consumer Recycled (PCR): Using plastic that has already lived a life as a milk bottle or food container, rather than creating “virgin” plastic from oil.
- Glass Refills: I am a strong advocate for refill systems, which allow us to reuse heavy glass bottles multiple times, eventually making the carbon cost worth it.
I promise to always be honest about the products I use. If a product comes in plastic, it is because I have weighed the carbon cost of shipping and recycling against the environmental impact of the material itself. I am constantly looking for the “third way”, packaging that is both low-carbon and truly biodegradable. Until then, I will continue to choose the most responsible options available today.
