Saving energy during waste paper recycling
In the paper industry, some 10 to 20 percent of the waste paper that goes into the recycling
process is left over as residual material depending on the process used. Specifically for this
branch of industry with its high requirement for energy, Oschatz has developed a concept
that not only guarantees utilisation of these residual materials in line with current
environmental legislation, but also makes considerable savings in respect of primary energy.
This is achieved through thermal utilisation of the residual materials in a combined heat and
power (CHP) generation process, in which the residual materials are utilised thermally by
being combusted in a firing and boiler plant. This combination of thermal utilisation with a
CHP generation process significantly reduces emissions and their impact on the
environment. In addition, the amount of waste dumped in landfill sites is greatly reduced, as
too are the costs of disposing of such waste.
An overview of the process:
conditioning of the low calorific value residual materials,
use of gas turbine exhaust gases as combustion air for simultaneous predrying of
the residual materials,
conversion of the energy from the high-pressure steam to electric power in a
