Product manufacturing
When modelling the manufacturing of your product you can choose between the typical processes for industrial production in all materials.
If we take one example of a wooden based product manufacturing like “Furniture production” modelling typically consists of cutting, gluing and assembly processes followed by surface treatments.
Energy demand is in this process primarily driven by ventilation and finishing activities.
The modelling of this manufacturing step includes:
- Process-level modelling of cutting, gluing, assembly and surface treatments results in a need for electricity and heat based on Ecoinvent’s “furniture production, wooden, 1kg, global”
- Explicit inclusion of material waste and manufacturing losses
- Separate modelling of high energy need surface treatments such as wet painting
- Variation across product types to reflect real manufacturing complexity
Manufacturing
We model manufacturing energy using Ecoinvent’s dataset “furniture production, wooden”.
The dataset is based on life cycle assessments of nine representative furniture products covering low- and medium-volume production.

Heat demand in the dataset is fossil-based.
Wet painting and plywood moulding is modelled as separate processes in the Målbar platform as they are not included in the above LCA.
Material waste varies significantly depending on product type.
Across the underlying studies, the average waste rate is approximately 22%. But Målbar LCA assigns average material specific waste rates based on our costumers statistical supplier data.
Electricity mixes and heat datasets are geographically specific.
