Circular business with the R-ladder

The R-ladder is a vital tool for circular entrepreneurs. It asks the question: how can you minimize your environmental impact? The higher you climb the ladder, the smarter you are using raw materials. In this blog, we walk through the steps using cardboard boxes as our case study, starting with the most sustainable option at step 1.

Step 1 - Refuse en Rethink

Do you use cardboard boxes for shipping? First, check where they might be unnecessary. The best way to save resources is simply not to use them. Ask yourself if certain products can be transported safely without any outer packaging at all.

Step 2 - Reduce

Use less cardboard. You can achieve this by switching to smaller boxes or, better yet, custom sizes made to the millimetre. Also, consider the material thickness: could you switch from double wall to single wall board? Looking for a perfect fit? Check out our Tailored boxes.

Step 3 - Re-use

Every business receives deliveries in boxes. Instead of ripping them open and binning them, save them. Use them for your own outbound shipments. Reuse is always more sustainable than recycling. Do you receive pallets of boxes you can’t reuse yourself? Visit our purchasing page. We buy surplus stock to ensure it gets a second life.

Step 4 - Repair, Refurbish, Remanufacture and Repurpose

If a box can’t be reused as a container, give it a new purpose. For example, shred old cardboard to create sustainable void fill for other shipments.

Step 5 - Recycling

If none of the steps above apply, choose recycling. Old boxes are turned into pulp, which forms the raw material for new packaging.

Step 6 - Recover

For cardboard boxes, step 6 should be the last resort. This involves recovering energy from materials that cannot be reused or recycled—for instance, incinerating waste to generate heat.

How to use the R-ladder

Your business relies on various raw materials, some with a heavier environmental footprint than others. Pick a specific product or material group and run it through the six steps of the ladder. Start at step one. For each step, brainstorm ways to limit the consumption of new resources.
