I was recently introduced to an sustainable packaging solution at work. Splosh provide refillable vessels for floor cleaner, laundry detergent, hand wash etc. Each product is provided in a concentrate capsule that is placed in the pack.
This is then filled with water that dissolves the capsule and mixes the formulation ready to use. Huge savings in the products supply chain are passed on to the consumer, who can re-fill the product using capsules ordered on the internet and sent directly to their door. This is a fantastic concept and a well executed marketing proposition. While it may not be the most innovative solution or one that focuses on the in-use consumer journey I think it is a fantastic product that has taken a bigger look at the picture and created an effective and most importantly sustainable solution.
