EKONO has conducted a series of studies targeted at specific segments
of the pulp & paper industry, and funded on a "multiclient"
For the past twenty-one years EKONO and Duoplan OY have issued this
publication annually. The objective is to provide information on
current environmental issues as well as on technologies available to
meet the current and expected future requirements. Graphs are
developed from EKONO's comprehensive emissions database which are
useful for benchmarking the performance of many different mill types.

The objective of this study was to analyze the impact of washer
performance and metal management on material and energy balances,
concentrations of metals and other non-process elements, and dry
solids concentrations of various fiberline streams. Several
different effluent recovery or reuse concepts were studied, including
both ECF and TCF sequences.
The objective was to explore the opportunities to reduce the
bleached kraft mill environmental discharges by recovering the bleach
plant effluent entirely or partially. Environmental performance
data were gathered, and the implications of both partially open and
completely closed water systems were determined for chemical balance
control, solid waste management, and recovery area loading.
The objective was to review and document the current low-effluent
technologies (proven or proposed), assess the implications of the
effluent-free technologies on several sample mills, assess the
economic implications and environmental impacts, and identify the
needs for further research and development.
