Use advice for data set The studied system boundary is Cradle to gate with options; module A5, modules C1–C4, module D
(A1–A3, A5, C1-C4 and D). The studied system covers the following steps of life cycle according to EN
15804: A1 Raw material supply, A2 Transport, A3 Manufacturing, A5 Installation to building, C1
Deconstruction, C2 Transportation of end-of-life C3 Waste processing, C4 Disposal and stage D the
benefits and loads beyond the system boundary, which consist of product reuse, recovery and
recycling. The life-cycle modules are listed in the following table.
The end of waste point of the production scraps is the point where it is processed to be ready to use
in following life cycles. For example for incinerated waste streams, it is the incineration of the
materials, which results as energy that is then available for consumption in the following life cycle.
For paper waste, it is ready to be used as secondary raw material after sorting. End of waste point of
the studied product is the step when material is used is crushed and/or landfilled and available to be
used to replace primary crushed gravel. EoW point of the packaging materials collected for recycling
in A5 module is the point when materials are collected and handled in the sorting plant. Due to the
insignificant amounts of packaging materials compared to the product mass, EoW treatments of
packaging materials were not modelled separately. |
