Mass Balance; A Way Towards a More Sustainable Future

Sustainability is the cornerstone of the Orthex Group strategy. One important way to increase sustainable business is to increase the use of renewable raw materials. Renewable, or bio-based, plastics often offer sustainability benefits over conventional plastics such as a reduced CO2 footprint.

Orthex will accelerate the transition towards a more sustainable use of global resources via the Mass Balance approach. Mass Balance means that renewable materials are mixed with fossil materials in the raw material production process. This reduces the amount of fossil-based plastic in the world.

The Mass Balance approach is a calculation-based principle. By keeping track of the quantities throughout the entire production chain, the renewable raw material can be allocated to specific products. Orthex is ISCC+ certified, which means that the mass balance accounting follows predefined and transparent rules, and each of our Mass Balance products carries the ISCC logo.


Which Products Will This Apply To?

We have started using Mass Balance raw material with our popular SmartStore™ Compact and SmartStore™ Compact Clear ranges. Each product will have at least 20 % of renewable content allocated to it, according to the mass balance approach. The CO2 footprint of the raw material used in the products will decrease by 37 % compared to conventional fossil-based plastic*.

The renewable content comes from production side streams, so it does not compete with food or land use.The renewable content consists mainly of kitchen waste (used cooking oil).
