Southern Lakes Laundries has installed a high-efficiency heat exchange unit for their main industrial washing machine that is delivery savings of up to $45,000 a year.

Southern Lakes Laundries retrofited the heat exchanger into their existing equipment without any disruption to their 364 day a year operation.

The project payback period is approximately 2 years.

New technology is turning sludge from waste water into valuable bio-fuel with environmental and financial benefits for a Southland meat processing plant.

It's a bubbling fluidised bed boiler, well-proven overseas for its ability to handle low quality fuels. The 8.5MW unit was installed at Silver Fern Farms' Finegand plant by Energy For Industry under a build, own, operate agreement.

A thermal energy audit of South Island MDF producer Dongwha Patinna identified seven energy management opportunities, and a buyer for excess fuel produced onsite - which together could be worth up to $288,000 a year.

After a half-day visit from an energy engineer to test and re-tune the burners on its boilers, Taylors Laundry Christchurch has found itself using 21,643 fewer litres of Light Fuel Oil (LFO) and saving $17,532 annually.

This 5% energy saving is in line with the Energy Efficiency and Conservation Authority's (EECA)estimate of the saving that most businesses using process heat can expect when they improve the efficiency of existing plants.
