One smartphone of 135 g, the average of 12 disassembled models from 2004 to 2015
This page shows what the product is made of and where each figure comes from. It shows no death toll. The toll is computed from this bill of materials from session 19, and published only once it has an uncertainty interval and has passed a backtest.
The average smartphone of a disassembly study of twelve models from 2004 to 2015: 135 g, of which 23.7% plastics, 22.6% lithium-ion battery, 14.0% circuit board, 9.9% aluminium, 8.7% other glass, 6.7% display glass, 6.3% steel and 1.2% copper. Phones have grown heavier since, so this is an older phone than the one in a reader's pocket. The battery is weighed but its cobalt, lithium and nickel are not yet traced, and that is the largest gap in this record.

What it is made of
Each line is one component of one smartphone of 135 g, the average of 12 disassembled models from 2004 to 2015: how much of it goes in, how much had to be produced for that, and where the figure comes from.
Down to raw materials
The whole chain multiplied out — everything one smartphone of 135 g, the average of 12 disassembled models from 2004 to 2015 needs, through every intermediate product, with every loss on the way included.

An input marked “not in the register” is counted by mass and reaches no supply chain yet. Industries appear as the euros or tonne-kilometres the bill of materials gives them.
How much of it is explicit
100% of this product’s mass is explicit in its own bill of materials.
Its whole chain draws on 188 g of materials, losses included. 42% of that is registered raw materials — the part the model can trace harm to — 58% is inputs not yet in the register, and 0% is a declared remainder.
The rest — 0.405 g — is a declared remainder: a published composition covered only part of the product, so the rest is carried as its industry’s average rather than invented.
In the input–output model it belongs to “Manufacture of computer, electronic and optical products” (FIGARO industry C26).
In the input–output model it belongs to “Manufacture of computer, electronic and optical products” (FIGARO industry C26).
The number this page does not show
The harm in this chain is not shown.
The model allocates the harm counted where each raw material is produced to the products that use it. That number is a count of people with a run behind it and no uncertainty interval yet, and nothing of that kind is published before the backtest of session 21. What this page can show without it is the structure: what the product is made of, and where each part of that knowledge comes from.
