Multiclient Studies

EKONO has conducted a series of studies targeted at specific segments of the pulp & paper industry, and funded on a "multiclient" basis.

Environmental Performance, Regulations and Technologies in the Pulp and Paper Industry (1995-2015)

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.

Optimization of Washing Processes and Metal management in a Low Effluent Bleached Kraft Mill (1996)

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.

Chemicals, Dry Solids and Solid Waste in a Low Effluent Bleached Kraft Mill (1994)

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.

Low Effluent Bleached Kraft Mill (1992)

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.
