Clean
Technology Brochure
The raw hide or skin is a by-product
of the meat industry and from this raw material the leather
tanning industry converts approximately 25% by weight
into leather. The production of leather from the raw hides
and skins involves an intensive use of water as well as
many mechanical and chemical processing steps. Consequently
the tanning industry generates considerable amounts of
solid, liquid and gaseous wastes. Well planned clean technology
practices through the use of minimising, re-cycling, and
re-use of water and solids following the best available
technologies (BAT), can allow tanners to comply with tough
environmental pressures.

THE TFL WHITE LINE SYSTEM
Leather in the form of shoes, upholstery, clothing and
merchandise offer their wearers and users enormous advantages,
though these are scarcely still perceived as such. Against
the numerous undisputed benefits discussion has recently
focussed on the risk of unwanted chemical uptake by the
human body. Governments such as that of Germany and the
legislators of the European Union (EU) protect consumers
by legislation and directives, although in the past there
has been little evidence of harm caused by leather.

Disposal
of leather goods
In todays industrial society, more and more importance
is being attached to the tanners and consumers responsibility
for active environmental protection. Leather is used to
make consumer goods which sooner or later end up as household

Risk assessment of leather dyestuffs
The identification of human health and evnironmental hazards
are important prerequisites for risk and life cycle assessment.
Good quality information on exprosure is needed to address
the risk objectively, and possible options for risk reduction.
Risk management should indeed start with a careful selection
of colorants that exhibit the required performance with
regard to substrate affinity, fastness and other boundary
conditions.
