This simplified 'Cradle to Gate' tray carbon footprint model is based on externally validated figures by SGS UK Ltd.
By changing the tray weight you will get a graph with the carbon footprint of Holfeld rPET and Holfeld rPET/PE trays and also trays in several other common material types.
The figures for Holfeld Plastics Ltd. trays are based on a survey carried out by University College Dublin according to Publicly Available Specification (PAS) 2050 - the product carbon footprinting standard.
This survey has undergone independent third party verification by SGS United Kindom Ltd. Holfeld Plastics have a fully verified carbon footprint model for their packaging which can calculate the global warming potential of our full range of trays offered to customers. Please download a copy of the verification certificate for details, or contact Holfeld Plastics Ltd. directly for more information.
