Case studies

Many piggeries have high energy needs - requiring hot water, lighting, food-preparation machinery and heating - seven days a week. Biogas is produced from the biological breakdown of organic matter and can be used
to generate energy.

A Taranaki piggery is harnessing biogas from its piggery feedstock to generate electricity, and hot water as well as reducing smells and CO2 emissions.

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.

At Mairehau High School, wellbeing comes first - and that includes providing a healthy and comfortable environment. With clean efficient wood energy delivering heat where it is needed, Mairehau High School students can learn at their best all year round.

Tachikawa Forest Products NZ Ltd in Rotorua committed to installing a 8MWth energy plant to be fired on waste-wood products to boost kiln drying capacity and clean up their waste disposal problem.
The majority of the biomass fuel required for the new 8MW th energy plant is created as a by-product of the manufacturing processes performed on the Tachikawa site.
