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 a chemical dosing application in a water treatment plant. Product stage The production of the plastic raw material was modeled via 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 systems) A3 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 Valencia (Spain). Pipes are transported over a distance of 1 700 km by means of a truck. Fittings, valves and measuring instruments are first transported to storage: measuring instruments via air freight (ecoinvent data record: Transport, aircraft, freight, intercontinental, RER U) over 5 000 km; fittings via truck over 450 km and valves also via truck over 150 km. A4 Afterwards these components as well as bolts, nuts, washers and brackets are transported to the installation site by truck over 1 400 km. The pump is transported to the installation site by truck over 1 500 km. For all transportations via truck the ecoinvent data record “Transport, lorry > 16 t, fleet average/RER U) was used. Loading capacity is 60%. For the installation of the whole system special solvent cement (0.4 kg/FU) and specific cleaner (0.2 kg/FU) for the jointing are necessary. These input materials are transported over 2 000 km by truck to the installation site. Outputs of the complete installation of the system are PVC pipe cut-off (0.06 kg/FU) and packaging waste (3.6 kg/FU) A5 whereof 95% is cardboard. Wood and cardboard are recycled; PE film, nylon belts and PP straps are incinerated. Transport distance to recycling is assumed to be 600 km, transport to incineration is 150 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 lifetime 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 use of the system is an important stage mainly because of the long reference service life time of 25 B6 years. 19 710 kWh of energy (ecoinvent dataset: Electricity, low voltage, production RER, at grid/RER U) per functional unit is necessary to run the two pumps. B7 No operational water use is necessary for the system. This stage is considered as not relevant. End of life stage De-construction of the system is mainly manual work. A small energy input is needed to cut the pipes. The C1 environmental impact is negligible 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 are 600 km for recycling and C2 150 km for incineration. It is assumed that all metal parts are recycled and all other parts are incinerated with energy recovery. The exported energy is in the form of electricity and thermal energy. Approximately 11.5% of the net energy content of C3 the incinerated waste is converted to electricity and 23.4% is converted to heat. Both are sold to external consumers. These values reflect the situation in Swiss municipal waste incinerators about 10 years ago, as reported in ecoinvent documentation. It is assumed that all metal parts are recycled and all other parts are incinerated with energy recovery. Therefore C4 module C4 is not relevant. 5
