1 October 2026. Walther Faltbox Group and MBRC THE OCEAN are working together to use recycled MBRC PLASTIC in durable reusable products. For this, the material was tested in various tools and products – including variants with up to 100 percent recyclate.
The right material mix
For the folding boxes, a mix of 60 percent MBRC PLASTIC and 40 percent virgin material proved particularly suitable. In the tests, the boxes achieved the required stability and matched comparable boxes made from virgin material in quality and functionality. According to Walther, the mix also makes for an economically attractive material option.
What MBRC PLASTIC is
MBRC PLASTIC is based on plastic collected from coastal and "ocean-bound" collection streams – waste gathered near coasts before it reaches the sea. For the folding boxes, recycled polypropylene (PP) is used. The material is slightly darker than virgin plastic, so the teams also tested how well it can be coloured: in a direct comparison, there was hardly any visible difference.
"I find it particularly exciting to use our material in an industrial reusable application. The requirements for folding boxes are high, and the joint tests show us how our material can be used for this application."
– Jasper Nikulka, CEO Germany, MBRC THE OCEAN
Dominik Lemken, Managing Director of Walther Faltbox Group, pointed out that the company has used recycled materials for many years and continuously tests how further recyclates can be used without compromising product durability.
Available on request
The material option is available for all Walther folding boxes and is used on customer request. For both companies, the project also provides insights into how recycled plastic streams can be used in industrial reusable logistics.
