Meat and dairy plant operators have been targeted among
new energy-efficiency initiatives announced by the Government,
aimed at improving business productivity, saving money and
reducing carbon emissions.
The energy sector, specifically transport and industrial
heat, were two key areas where such initiatives had the
potential to save thousands of dollars for businesses and
reduce carbon emissions, Energy and Resources Minister Simon
Meat and dairy plants were the biggest users of industrial
heat and more than half of about 200 plants nationwide used
Under the initiative, the Energy Efficiency and Conservation
Authority (EECA) would work with plant operators to identify
energy savings, Mr Bridges said.
That could be through improvements to heat recovery processes
or boiler tuning, or, where economic, fuel switching, for
example from coal to wood.
The authority would then work with operators to develop
business cases or feasibility studies.
Overall, businesses were expected to see ongoing savings of
up to $700,000 in energy costs each year - about $70,000 per
site over the expected life of the improvements.

It would also save an estimated 7000 tonnes of carbon
each year, which was equivalent to taking up to 2000 cars off
the road, Mr Bridges said.
Southern-based co-operatives Silver Fern Farms and Alliance
Group have their own energy management initiatives.
Last year, Silver Fern Farms announced it was investing about
$1.4 million in an initiative to deliver cost savings of
$70,000 a year within two years.
The company was working with EECA to achieve annual energy
savings of more than 13GWh.
Since 2000, Alliance Group's energy-efficiency programme had
reduced fuel and electricity use, per unit of production, by
32% and 14% respectively, energy management co-ordinator
Aiann Cairns said.
The company had implemented a range of initiatives including
energy monitoring, re-using waste heat, improving lighting
efficiency and control, improving the refrigeration process
and boilers, and product process changes.
The most recent was consolidating and upgrading the company's
rendering operations in the southern region at its Lorneville
The $25 million plant, completed earlier this year, processed
raw products from Mataura, Makarewa and Lorneville.
The company expected that after a year of operation, it would
save 9000 tonnes of lignite and more than 1.5 million kWh of
electricity a year, enough to power 170 homes every year, Mr
The other energy-efficiency initiatives announced were
expansion of the heavy-vehicle fuel-efficiency programme and
a fuel-efficient tyres initiative.
The Government will spend $1.1 million to double EECA's
current heavy-vehicle fuel-efficiency programme to reach an
additional 150 small to medium-sized vehicle fleets over
The programme was expected to deliver about $1.2 million of
diesel savings a year and reduce carbon emissions by about
7500 tonnes a year.
EECA will work in partnership with industry to run an
information campaign to increase consumer awareness and
uptake of fuel-efficient tyres.
The Government will spend $2 million over two years and the
initiative was expected to save about 2.5 million litres of
fuel each year, and reduce carbon emissions by about 6000
tonnes a year.
