Creating economic wealth from emissions reduction – a case study of recycling

The waste and recycling industry contributes close to 3% of Australia’s direct emissions. However, recycling abates much more by capturing the embodied energy of the recovered materials. We can create a more sustainable Australia by reducing emissions, increasing recycling and growing new green jobs.

Rebuild after COVID-19: All governments should ban organics to landfill

Organics to landfill make up more than half of all waste to landfill in Australia. They are also responsible for a fair amount of the waste sector's GHG emissions. How can we create environmental benefits and stimulate the economic growth sorely needed post COVID-19?

Where to with food waste

If global food waste was a country, it would be the third largest emitter of greenhouse gases in the world, behind the U.S. and China One thing we can do to combat climate change as individuals, households, local councils, state governments and federal governments is address food waste to landfill. So, what are our options?

Carbon abatement- the waste sector can do much more

Projections show Australia is very unlikely to meet its current 2030 carbon reduction targets, with recent reports of increasing greenhouse gas emissions (GHG) from all sectors other than the electricity and agriculture industries. Australia needs to do more and the waste and recycling sector can lead the charge in emissions reduction.

Actions for a circular economy

Following up on his earlier Circular Economy article, Mike Ritchie reviews the European Union Circular Economy Action Plan report of 54 actions and adjusts those actions to propose an equivalent action list for Australia.

Driving a circular economy

A circular economy is necessary to minimise landfill, increase resources recovery and protect our natural environment. A strong local reprocessing sector will also generate new jobs, support the economy and safeguard Australia from international developments such as China's National Sword. Mike Ritchie outlines the key drivers for a strong Circular Economy in Australia.

Commercial Organics Recycling- success is a long way away

FOGO diversion from landfill is one of the cheapest global warming abatement options. It is also relatively easy to do and should be prioritised by Government.

UN warns of possible 3°C temperature rise by 2100

After combining and analysing data from five distinct global meteorological and marine observation datasets, the UN warns that we might see temperature increases 3-5°C by 2100.

The science is in. Again.

The news on our climate is not good as the recently released CSIRO and BOM report confirm the continued warming of Australia’s climate and oceans: “Observations and climate modelling paint a consistent picture of ongoing, long‑term climate change interacting with underlying natural variability.”

Composting massively reduces greenhouse gas emissions compared to landfill

At a recent meeting with Local Government Mayors and CEO’s, a claim was made that transporting organics by truck to a distant compost facility (in this case 150km away) would emit more greenhouse gases than landfilling it locally. Thinking that the carbon forcing factor of methane from landfill (25 times CO2) would render that claim incorrect, I thought I should go back and check the maths.

Energy from Waste (EfW) can deliver 9% abatement of Australia’s emissions

There has been much said recently about the need to use nuclear energy as a bridging technology while renewable technologies and battery systems in particular, are improved. It seems to me that waste and recycling have again been overlooked as serious contributors to Australia’s emission abatement task. In 2006 Warnken ISE and SITA Australia published […]
