What is World Earth Day?

World Earth Day is a global event held on 22nd April each year, dedicated to raising awareness of environmental issues and driving action to protect our little planet. Launched in 1970, it now mobilises more than one billion people across 193 countries.

The 2026 theme, ‘Our Power, Our Planet’, is all about how environmental progress is built through the smaller decisions we make every day, not just big, sweeping policies. For businesses, packaging is one of those decisions, and it’s such a simple change to make. It affects material consumption, waste generation, transport weight and end-of-life recyclability. And with Extended Producer Responsibility (EPR) legislation now in full swing in the UK, sustainable packaging has a direct impact on your costs too.

If you acted on our Earth Day 2024 guide, this article takes things further with specific product swaps you can make today.

Five packaging changes to make for World Earth Day 2026

1. Switch to right-sized recyclable cardboard boxes

A box that fits your product reduces void fill, lowers transport weight and cuts material waste in a single move. Here at RAJAPACK, we offer more than 900 different box sizes, and over 1,500 of our products contain recycled materials. Right-sizing also reduces your PEPR-modulated fees, which are calculated partly by packaging weight.

Browse our recyclable cardboard box range to find the right-sized boxes for your business.

2. Replace plastic mailers with paper-based alternatives

Plastic mailing bags are among the most common sources of non-recyclable waste in e-commerce despatch. Our paper-padded mailers and cardboard envelopes are fully recyclable. And our bubble-lined mailer goes further as the bubble layer separates from the paper outer, so both materials can be recycled separately, which is something standard plastic mailers can’t do.

Explore our paper mailers and cardboard envelopes to find the right fit.

3. Move to reusable packaging with Movopack

Reuse removes the disposal problem entirely, rather than replacing one single-use material with another. Movopack pouches, exclusively available through RAJAPACK, are made from post-consumer PET (Polyethylene terephthalate) materials, including recycled plastic bottles. They’re designed for multiple use cycles before being fully recycled at end of life.

Research from City to Sea and Ecosurety found that 77% of UK consumers now expect all retailers to offer reusable or returnable packaging as a permanent alternative to single-use waste. Find out more about Movopack reusable packaging.

4. Swap polystyrene for recyclable cardboard protection

Polystyrene is widely rejected by kerbside collection schemes. We’ve replaced polystyrene corner protection in our range with 100% recyclable cardboard corner protectors that perform the same protective function. Our packaging specialists can help you find paper or cardboard alternatives for other polystyrene formats in your operation, and you can explore the options in our eco-responsible packaging selection.

5. Audit your packaging using the 5 Rs

Our 5-Rs framework (Reduce, Reuse, Replace, Renew, Recycle) gives you a structured way to assess each material in your packaging operation and prioritise improvements to create a circular economy. You don’t need to act on all five at once. Start with the area of highest volume or cost, and work through the others quarter by quarter. Our complete RAJAPACK 5-Rs guide walks you through each step in detail.

What to do next

The changes above aren’t seasonal. Every swap you make delivers measurable benefits in waste reduction, material cost and regulatory compliance throughout the year. World Earth Day 2026 is a good reminder of the impact we can all make, but the opportunity for real change is year-round.
