Declaration of general information sustainability.ps@georgfischer.com 1.1 Introduction GF Piping Systems is one of the three divisions within Georg Fischer Corporation and a leading provider of plastic and metal piping systems with global market presence. The product portfolio includes pipes, fittings, valves and the corresponding automation and jointing technology for industry, building technology as well as water and gas utilities. Georg Fischer Piping Systems proactively incorporates its environmental responsibility into its everyday business activities. Because we understand environmental awareness as one of the corporation‘s core values, internal structures and processes are geared towards sustainability. In this context, life cycle assessments are the correct tool to gain insight in the different life cycle phases of our systems. This EPD is based on a detailed background report written by the Flemish Institute for technological research (Vito). The report is in line with EN 15804 “Sustainability of construction works – environmental product declarations – Core rules for the product category of construction products”. The data of the study complies with the quality requirements set out in EN 15804 (EN 15804+A1:2013, Sustainability of construction works - Environmental product declarations - Core rules for the product category of construction products). Data regarding the production of the pipe system components is company specific and was provided by GF Piping Systems.

2.3 Scenarios and additional technical information The analyzed case represents an exemplary system for the transport of sea water to a power plant where it is used for process cooling. Product stage The production of the plastic raw material was modeled by generic European data (source: ecoinvent) and A1 complemented by specific data from GF Piping Systems to consider the company specific formulation of the raw material. Wherever possible, the specific transport distances were taken into account. Data from ecoinvent with the A2 respective parameters was used to model the transportation. The use of energy is the most important input for this process step. Pipes are extruded while fittings and valve parts are injection moulded. Each of GF Piping Systems’ worldwide production sites is certified according to ISO 14001 (Environmental management systems) and to OHSAS 18001 (Occupational health and safety management A3 systems) or is currently in the certification process. For the production of GF Piping Systems components, electricity mixes for the respective country/continent were used. The production of external products was modeled using generic ecoinvent data records for the process. Construction process The system is installed in Jiaxing (near Shanghai), China. Pipes, bends 90° and flange adapters, brackets as well as bolts, nuts and washers are transported over a distance of 127 km by means of a truck directly to the installation site. Measuring instruments are transported by air freight (10 885 km) and truck (127 km) to the installation site. The other components are first transported by truck to A4 storage: Installation fittings (150 km), backing flanges (560 km), bends 45° (130 km), butterfly valves (456 km), check valves (250 km), brackets (700 km). Afterwards they are transported by air (9 262 km) and truck (127 km) to the installation site. For all transportations by truck the ecoinvent data record “Transport, lorry > 16t, fleet average/RER U” was used. Loading capacity is 60%. For the installation of the whole system 72 kWh welding energy (Chinese electricity mix) is needed. Furthermore, specific cleaner (0.2 kg/FU) is necessary. The cleaner is transported by truck (1 027 km) and air freight (9 262 km) to the installation site. A5 Outputs of the complete installation of the system are PE pipe left over (5 kg/FU) and packaging waste (118 kg/FU) whereof 77% is cardboard. All waste is going to landfill. Transport distance to landfill is assumed to be 200 km. Transport is carried out by truck. Use stage There are no further environmental impacts arising from the use of the system. This stage is considered as not B1 relevant. The system is designed to be operated without repair, maintenance, replacement or refurbishment during the reference service life time. This is subject to the condition that the system is operated according to the specifications given by GF Piping Systems. B2-B5 The lifetime of a valve is mainly influenced by the actuation cycles. The number of actuation cycles the valves are tested for is not reached during the life time of the evaluated system. It is possible that in individual cases components of the valve (e.g. seals) must be replaced. In this case the environmental impact is negligible compared to the impact of the whole system and below the cut-off criteria defined in EN 15804. The operational energy use of the system is an important stage because of the long reference service life time of B6 25 years. 10 082 200 kWh of energy (ecoinvent dataset: Electricity, medium voltage, at grid/CN U) for the pump during the use stage is necessary per functional unit. B7 No operational water use is necessary for the system. This stage is considered as not relevant. End of life stage A small energy input is needed to cut the pipe into smaller pieces. The environmental impact is negligible C1 compared to the impact of the whole system and below the cut-off criteria defined in EN 15804. Transportation to the end of life treatment facilities is carried out by truck. Distances to recycling and landfill are C2 200 km. C3 All metal parts of the system – in total 2 419 kg - are recycled. C4 All other parts – in total 4 146 kg - are going to landfill. 5
