be prepared for recycling and the manufacturer is obliged to have an
environmental policy which must be adhered to in each country where the
company implements its operational policy.
The energy requirements include a demand that the computer and/or
display, after a certain period of inactivity, shall reduce its power
consumption to a lower level in one or more stages. The length of time to
reactivate the computer shall be reasonable for the user.
Labelled products must meet strict environmental demands, for example,
in respect of the reduction of electric and magnetic fields, physical and
visual ergonomics and good usability.

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 bio-accumulative* processes. Flame retardants have
been found in human blood and researchers fear that disturbances in
foetus development may occur.
The relevant TCO’99 demand requires that plastic components weighing
more than 25 grams must not contain flame retardants with organically
bound bromine or chlorine. Flame retardants are allowed in the printed
circuit boards since no substitutes are available.
