Scania Annual Report 2011

SCANIA’S SUSTAINABILITY WORK
51
Continued work is under way to limit the quantity of industrial
run-off water that must be treated. The phosphating
unit in Oskarshamn (Sweden), for example, has reduced the
quantity of run-off water by 90 percent to the current 1 litre
per m 2 of treated sheet metal surface, which is low for a unit
of this type.
As for chemicals, improvement efforts focus on decreasing
their use and transitioning to alternatives with lower
environmental impact.
Better logistics systems
Process development in logistics is profitable, reducing
transport work and thus emissions. This work includes
increasing the load factor for goods shipments and developing
transport systems that support varied goods volume.
Increased use of intermodal shipments, which combine different
modes of transport, often also leads to lower carbon
dioxide emissions.
Carbon dioxide emissions during a
product life cycle
Most of the environmental impact of Scania products occurs
when vehicles and engines are in use. A large element of
environmental impact is carbon dioxide emissions.
The production of a Scania truck generates around one
tonne of carbon dioxide. Component haulage and vehicle
delivery create another tonne. A long-haulage truck that is
driven fuel-efficiently for 200,000 km per year emits approximately
170 tonnes of carbon dioxide during one year of use.
The big difference in emissions between production and
vehicle use is an important reason for Scania to support the
environment work of its customers.
Recycling
Recycling continues to increase, and during 2011, Scania
disposed of 83,200 tonnes of waste (excluding foundry
sand), of which nearly 85 percent was utilised for recycling
of materials and recovery of energy. Waste to be sent for
off-site disposal, and mainly classified as hazardous, totalled
8,100 tonnes in 2011.
In development work, Scania’s objective is to reduce the
quantity of waste that is not recyclable, as well as residual
products, so they can be treated and recycled. Scania
provides detailed dismantling and disposal protocols for
end-of-life treatment of vehicles. Many parts are designed
for recycling and are labelled for easy identification.

Emissions from goods shipments were calculated as specified by the Network for
Transport and Environment (NTM). An in-depth account of measures and results as
well as a summary of environmental performance by production unit are available at
