Clive Scouring in Napier is capturing heat previously released as waste and turning it into energy savings worth more than $100,000 a year.

Clive Scouring captures energy from its chimney and uses it to pre-heat water for other processes at the plant.

The project has a one-year pay back and on top of the energy savings, the new system has also cut the company's annual CO2 emissions by 516 tonnes.

Good lighting design and control can save up to 75% of industrial buildings lighting costs.

This technical guide outlines two key ways that industrial lighting operating costs can be reduced. It includes a range of no cost/low cost actions that can be undertaken as well as several actions for reducing energy use associated with industrial lighting which have a longer payback period.

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.
