Bleach plant effluents can contain a large amount of heat, which will be wasted if the effluents are discharged without heat recovery. Heat exchangers can be installed to recover some of this heat for other beneficial uses around the mill, including hot water heating (Kramer, et al., 2009. p.92)

In the same US based mill, corresponding annual cost savings are $2.4 million (2003 dollars). At the capital investment of $1.6 million, the payback period is estimated as 0.7 years (Kramer, et al., 2009. p.92). |
This Energy Guide discusses energy efficiency practices and energy-efficient technologies that can be implemented at the component, process, facility, and organizational levels.
In one US based plant, energy savings are estimated to be 939 000 GJ/year (Kramer, et al., 2009. p.92).
