WASTE MANAGEMENT
South Africa
In South Africa key players in the cement industry are cur-
rently receiving waste tyres for use in cement kilns from
REDISA. Waste tyres can be utilised as a substitute (through
co-processing) for up to 20 % of current coal usage. At PPC,
indications are that waste tyres will replace 20 % of coal
usage at its De Hoek plant alone, where Management has
stated that “the co-processing of waste in cement kilns
not only reduces cost, but also reduces carbon emissions
from cement manufacture and reduces the need for non-
renewable energy.”
There are other cement producers who are also investi-
gating the burning of waste tyres to reduce the cost of fuel,
eg, Natal Portland Cement (NPC-InterCement), AfriSam and
La Farge. The users have benefited from the lower cost of
the substitution of a portion of their traditional fuels and find
that the tyre delivery system is well coordinated and know
in advance when their delivery will be made and how many
tonnes they will receive, therefore making planning easier.
REDISA supports sound waste management recycling
technologies through the conversion of waste tyres into
social, economic and environmental benefits.

Hefty fees and penalties
await consignors of cargo
who do not adhere to the
new Container Packing
Code of Practice and the
verification of Container
Weight Regulations for
transport. Consignors will
be liable for all costs as-
sociated to any damage
incurred to property and
the environment due to
non-compliance of the
new regulations. Local
and International industry leaders and regulators from the South Afri-
can Maritime Safety Authority (SAMSA) and the National Department
of Transport, gathered in Durban recently for the third International
Cargo Transport Units (CTU) Packing Roadshow, where the importance
of complying with the new CTU codes and weight verification Regula-
tions were addressed and discussed. The new IMO/ILO/UNECE Code
of Practice for CTU Packing is available and can be downloaded from
the UNECE website.
