Pharmaceutical packaging is currently undergoing a makeover, and it’s not just about aesthetics. With climate change at the forefront of global concerns, industries of all kinds, are stepping up their game. Packaging might not be the hero we talk about often, but it plays a vital role in both healthcare and protecting our planet.
Curious about how the pharmaceutical world is tackling sustainability challenges without compromising safety or functionality? Let’s break down the innovative ways this industry is going green while staying true to its purpose.
The Shift to Sustainable Pharmaceutical Packaging
1. From Plastics to Bioplastics
Traditional plastics have dominated pharmaceutical packaging for decades due to their durability and affordability. Enter bioplastics, made from renewable sources like cornstarch or sugarcane, these materials are biodegradable and significantly reduce reliance on fossil fuels.
Many companies are already rolling out bioplastic packaging for over-the-counter medicines and prescription drugs, ensuring the packaging still meets all safety and sterility requirements while being kinder to the planet.
2. Reducing Packaging Waste
Raise your hand if you’ve opened a box and found unnecessary layers of packaging—think stickers, inserts, multilayer boxes, and unnecessary wrappers. Fortunately, companies are catching on to the idea that less is more.
New designs focus on simplifying packaging without jeopardising product integrity. By removing redundant layers or shrinking box sizes, pharmaceutical giants are not only reducing material use but also improving transport efficiency (fewer materials = smaller loads = lesser emissions).
3. Recyclable Innovations
Not all pharmaceutical packaging can be composted or biodegraded. However, designing packaging that’s 100% recyclable is a practical step forward. For example:
- Mono-material Blisters: Traditional blister packs have a mix of materials like aluminium and PVC, making them non-recyclable. Innovators are now opting for blister packs made purely of one recyclable material, such as aluminium or PET.
- Recyclable Paper Labels and Boxes: From product instructions to outer cartons, switching to sustainably sourced and recyclable paper is another way to reduce impact.
4. Glass Makes a Comeback
Call it a comeback, or simply a sustainable classic. For years, glass has been eclipsed by lightweight plastics. But as an endlessly recyclable material, glass is being increasingly used for pharmaceutical packaging once again, especially for products that require airtight, sterile solutions such as vials, ampoules, and syringes.
Additionally, advancements ensure modern glass is lighter and shatter-resistant, answering concerns about transport and safety while keeping sustainability goals in check.
5. Closed-Loop Systems
One powerful concept gaining traction in pharmaceutical packaging is the closed-loop system. This means that packaging materials are retrieved, processed, and reused, over and over.
For instance, pharmaceutical bottles and containers can be collected from consumers or healthcare centres, cleaned, sterilised, and reused by manufacturers. Closed-loop systems dramatically cut waste generation and encourage a circular economy.
The Role of Regulations and Industry Policies
Many sustainability efforts in pharma packaging are driven by stringent policies and international regulations. The European Green Deal, for example, mandates that all packaging in the EU must be reusable or recyclable by 2030.
What does this mean for packaging? Companies at the forefront are treating regulations as an opportunity to improve business models while appealing to eco-conscious consumers.
What’s Next for Sustainable Medicine Packaging?
The path to sustainability is a process. More research, investment, and collaboration will be key to building a sustainable pharmaceutical packaging industry.
We can expect innovation in:
- Advanced biodegradable materials
- Fully circular supply chains
- More digital healthcare functionalities to reduce packaging usage
