The environmental demands impose restrictions on the presence and
use of heavy metals, brominated and chlorinated flame retardants,
CFCs (freons) and chlorinated solvents, among other things. The
product must be prepared for recycling and the manufacturer is obliged

country where the company implements its operational policy.
The energy requirements include a directive that the computer and/or

Environmental requirements
Flame retardants
Flame retardants are present in printed circuit boards, cables, wires,
casings and housings. Their purpose is to prevent, or at least to delay
the spread of fire. Up to 30% of the plastic in a computer casing can
consist of flame retardant substances. Most flame retardants contain
bromine or chloride, and those flame retardants are chemically related
to another group of environmental toxins, PCBs. Both the flame
retardants containing bromine or chloride and the PCBs are suspected
of giving rise to severe health effects, including reproductive damage in
fish-eating birds and mammals, due to the bioaccumulative* processes.
Flame retardants have been found in human blood and researchers fear
that disturbances in foetus development may occur.
