EcoPlasBrick panel general description

In particular, the LCA will be performed on a specific panel used for vertical indoor rooms division. In the following are provided brief descriptions for the LCA phases, and the results achieved up to now

The panel is made of a core of mixed recycled plastic waste (densified) roughly grinded, welded through temperature and pressure with one or two face-sheets (skins) of plasterboard. Metal profiles are inserted between the core layer and the skins as reinforcement of the panel.


LCA – PhasesThe LCA study is performed in accordance with internationally recognized guidelines (ILCD Handbook: General guide for Life Cycle Assessment - Detailed guidance) and standards (ISO 14044:2006 and ISO 14040:2006). It is structured in a series of steps, which are:

1. LCA goal & scope definition 2. Inventory analysis (LCI)

3. Impact assessment (LCIA) 4. InterpretationGoal and scope definition

LCA – Goal and scope

• Goal and Scope definition phase aims to define how big part of product life cycle will be taken in assessment and to what will assessment be serving. The criteria identified and specific time horizon are described in this step.

• In particular, the analysis of the energetic and environmental impacts of the innovative recycled plastic based panel has been performed, considering

“Cradle to grave” life cycle:

Production processUse phaseEnd of life


LCA – Goal and scope

In order to perform the LCA, a proper Functional Unit has been defined

• Functional unit is represented by 0,5 m2 of panel surface, with 0,1 m of thickness and 23 kg of weight.

• All data regarding materials and energy consumption will be referred directly or through a proportion, to this functional unit

• All calculated impacts (e.g. global warming potential, acidification potential, eutrophication potential, use of non renewable resources, etc.) will be referred to the selected functional unit


LCA – Inventory analysis (LCI)

• Inventory analysis is the description of material and energy flows within the product system and especially its interaction with environment, consumed raw materials and emissions to the environment. All important processes and subsidiary energy and material flows are described here.

• In the following all the collected information on the EcoPlasBrick panel are reported.


Main components of the panel:• Skin material constituted by 1 cm (thickness) of

plasterboard on both side of the panel. The plasterboard density is 800 kg/m3. It is provided by local producers.

• Core material made of 8 cm (thickness) of densified mixed plastic waste with a polyurethane foam. The core total density is 300 kg/m3.

• Metal profiles constituted by:Hollow structural section rectangular cold formed

according UNI 7813-83 (50x30x1.2): total weight 5.70 kg;2 steel plates (80x60x5)mm: total weight 0.37 kg;32 cm of weld;8 anchor screws.

Provided by local producers.



Core composition:• Densified material:

Aggregate density: 200 kg/m3 Transported from Treviso (Centro Riciclo Vedelago)Available LCA for other data

• Two-components Polyurethane foam:Polyurethane density: 100 kg/m3The two components-polyurethane foam has to be stored

at a temperature of -5°C than room temperatureTransported from Reggio Emilia (Knauf insulation, Turin)



Production process of the panel:• A first layer of skin (plasterboard) is placed in a mold.

• The densified material-polyurethane mix is put on the skin layer in the mold.

• The second layer of skin is placed on the mixture.

• The panel made of the three layers is pressed by using a press (1,5 CV) for 15 seconds, or using simple clamps.

• The cure phase takes around 30 minutes at room temperature.
