The environmental benefits of SIGNATURE PACK from SIG have been confirmed by a critically reviewed ISO-conformant lifecycle assessment (LCA) – the world’s first for a mass balance product.
The SIGNATURE PACK from SIG is the world’s first aseptic carton pack linked to 100% plant-based renewable materials. The LCA showed significant reductions in environmental impacts across all 10 categories as a result of the substitution of fossil-based polymers with mass balance plant-based polymers made from tall oil (a by-product of paper manufacturing).
The carbon footprint of SIGNATURE PACK is – on average across Europe – 66% lower than the carbon footprint of a standard SIG 1-litre carton pack of the same format across its lifecycle, based on the Europe-wide LCA.
Said Udo Felten, Manager Product Related Global Environmental Sustainability & Affairs at SIG: “The environmental impacts of every product innovation at SIG are evaluated through Europe-wide LCAs that conform with the rigorous requirements of recognised ISO standards. The results for SIGNATURE PACK show that SIG’s innovative mass balance approach has significant environmental benefits.”
The independent, critically reviewed LCA of SIGNATURE PACK was conducted in accordance with recognised international standards, ISO 14040 and ISO 14044 by the Institut für Energie und Umweltforschung (IFEU/Institute for Energy and Environmental Research) in Germany.
IFEU agreed to conduct the LCA when it became clear how valuable SIG’s mass balance approach could be in making mainstream polymer production more sustainable.
Commented Frank Wellenreuther, Project Manager at IFEU: “The application of the mass balance approach in the production of polymers is an important driver to facilitate an increasing substitution of fossil resources by biogenic resources for the production of polymers. To model the examined products strictly on their physical properties would fail to acknowledge this function of the mass balance approach.”
Driving more sustainable plastics
SIG chose a mass balance approach because it supports a wider transition from fossil to bio-based raw materials within the conventional and highly efficient polymer industry, instead of using niche small scale producers with a limited number of plastic grades.
Added Felten: “With the mass balance approach, SIG offers customers the environmental benefits of linking to 100% plant-based renewable materials, alongside the product quality and functionality which come from grades of polymer that are only available through mainstream production.”
