ENDING PUBLIC NATIVE FOREST LOGGING IN NSW - Petition to be discussed by Legislative Assembly

An ePetition to the NSW Legislative Assembly calling for the ending of public native forest logging will be discussed by the Assembly on September 15 at 4 p.m.  (To be eligible the petition required 20,000 signatures by the end of the petition period.  21,046 NSW residents signed this online petition.)

The Petition Text in Full:

To the Speaker and Members of the Legislative Assembly,

Public native forest logging is pushing iconic species like the koala, swift parrot and greater glider towards extinction.

The 2019/20 Black Summer bushfires burnt over 5 million hectares of forest and have left them more vulnerable to the impacts of logging. The Natural Resources Commission (NRC) and the Environmental Protection Agency have recommended that in bushfire affected areas logging should cease entirely or face tighter restrictions, as current logging practices may cause irreversible damage to ecosystems and wildlife.

Logging of public native forests is tax-payer subsidised. Forestry Corporation’s Hardwood Division has been operating at a significant loss for the past decade. In 2020/21 it ran at a loss of $20 million, with predictions that it will face losses of $15 million until 2024.

Reports also show our state forests can generate far more income through their protection than from logging, through recreation, tourism and carbon abatement.

The Western Australian and Victorian Governments have already committed to ending this industry and have developed transition plans to support affected workers and businesses.

The petitioners ask the Legislative Assembly to:

1. Develop a plan to transition the native forestry industry to 100% sustainable plantations by 2024.

2. In the interim, place a moratorium on public native forest logging until the regulatory framework reflects the recommendations of the leaked NRC report.

3. Immediately protect high-conservation value forests through gazettal in the National Parks estate.

4. Ban use of native forest materials as biomass fuel.

AN ALTERNATIVE TO WARMING HOMES IN WINTER

While we move away from fossil fuels, it does not make sense to turn to lithium-ion batteries and another mined resource. It is exciting that a simpler method is keeping people comfortable in our high-tech age.

With the gas and electricity disruption to Europe, Finland has designed a heat storage unit that warms peoples’ homes by little more than a steel container filled with sand.

That 'little more' includes solar energy. The sand battery is connected to the grid, turned on in summer and hot air piped through the sand heats it to 500o-600oC, which keeps people warm through the long European winter. This way people in Kankaanpää, a town near Helsinki, warmed their homes, office buildings and public swimming pool by a 7 metre insulated silo and 100 tonnes of  sand.

Finland’s Polar Night thermal energy also delivers high temperature heat for industries, and is a useful replacement for gas, removing up to 16% of emissions. Chief executive officer Markku Ylönen says a bigger battery 20 metres in diameter and 10 metres high can be quickly built in any steel workshop, and on the economics scale 100 times bigger equates to only a 20 to 30 times in cost.

Thermal energy is not new, but until recently burning gas has been cheaper to generate the higher temperatures needed for industry. Australia's ANU Sustainable Energy Systems (SES) Centre is focused on replacing old gas heat pumps with thermal, to deliver greater than 1,000ºC temperatures to factories.

"Stored thermal can be used in food processing, the aluminium industry, cement manufacture, iron and steel, ceramics and plastics," says ANU director Professor Andrew Blakers.

"A few thousand cubic metres of storage will keep a factory running but as thermal storage can't be piped in like gas, factories will need to install their own rooftop systems and build their own storage silos, for heat using cheap daytime solar electricity.”

SES has already patented thermal storage similar to Finland’s using molten silicon instead of sand, and is looking to trial crushed rock and molten salt.
