The results represented below are based on the Life Cycle Assessment (LCA) study carried
out on the products Terbond ® , Terbond ® A, Terbond ® TH and Terbond ® R with the aim to
inform the public and the interested parties about the environmental performance of its
production process.
The methodology used follows the rules described in the standard ISO 14044:2006, in line with
the International EPD System.
The reasons of the LCA study arose from the need to have a precise processes accounting
and to highlight potential improvements that could be started in order to increase the
environmental, energetic and economic efficiency and effectiveness of the processes. In
addition the purpose was to quantify and to communicate the environmental advantages
deriving from the use of non virgin raw material.
2.1 The Evaluation Method
The assessment of environmental performance was carried out according to the PCR 2010:10
“Product Category Rules (PCR) for the assessment of the environmental performance of UN
CPC 27922, Nonwovens for different purposes other than clothing” and to the “General
Programme Instructions for Environmental Product Declaration”.
2.2 The Functional Unit
The functional unit is represented by 1 kg of Terbond ® family.
The environmental information is represented with surface unit 1 m 2 .
2.3 The System Boundaries
The life cycle of Terbond ® products includes Upstream, Core and Downstream processes (Fig.
1). The system boundary determines those unitary processes which have to be included in the
LCA study.
