Optimizing the operating strategy of a pulp and paper mill using the mind method

The MIND method is used to optimize the operating costs of a pulp and paper mill. The optimization includes studies of the effects of material and energy flows, as well as non-linear relations between them. The results show that it is possible to achieve large savings in the pulp and paper mill simply by changing the operating strategy of the existing equipment units. It is also apparent that the percentage of recycled fibres strongly influences possible savings.
