Ask us anything: Energy from Waste

Energy from Waste (EfW), also known as ‘energy recovery,’ safely converts non-recyclable materials (think contaminated plastics, food-soiled packaging or textiles), into a source of energy such as electricity, fuel, or heat. 

It’s not an alternative for recycling. It’s what happens to waste after we’ve reduced, reused and recycled everything we can.

You can see where it sits in the waste hierarchy diagram below.

Why energy from waste matters

• Reduces landfill: Diverts non-recyclable materials that can't be composted or recycled, helping preserve our limited landfill capacity.
• Generates clean energy: Converts waste into reliable, locally-generated baseload electricity that powers our region.
• Supports recycling: Works alongside existing recycling and resource recovery systems - not in competition with them - by focusing only on residual waste.
• Improves environmental outcomes: Reduces greenhouse gas emissions from landfill using proven, advanced combustion and emission control technologies that meet strict environmental and health standards.
• Recovers valuable resources: Plays a vital role in the circular economy by extracting metals and other materials that would have otherwise been buried in landfill.

The goal is always to recycle first. Energy from Waste handles what's left — what would otherwise go to landfill.

Energy from Waste can safely process household waste (what we call municipal solid waste or MSW). But in Australia, we only want to receive materials that genuinely can't be recycled.

When households separate their waste properly, it means we're only processing what truly can't be recycled or composted.

So what actually goes to Energy from Waste? Things like:

• Soiled pizza boxes
• Greasy plastic wrap
• Raw meat trays from supermarkets
• Plastic lined cardboard coffee cups
• Laminated pouches
• Nappies and hygiene products
   

No — and the evidence proves it.

Countries with the highest recycling rates also use energy recovery as part of integrated waste management:

🇨🇭 Switzerland: 53% recycling + 47% energy recovery

🇩🇰 Denmark: 50% total recycling + 49% energy recovery + 1% landfill

🇪🇺 European nations where over 450 facilities operate maintain strong recycling programs

Why? Because energy recovery handles what can't be recycled, not what can be.

The goal is always to recover whatever we can through reuse and recycling first, followed by energy recovery—with landfill as the last resort.

Energy recovery from waste works like conventional coal or gas combustion where the steam powers a turbine to produce electricity. But instead of using fossil fuels, Energy from Waste technology is highly efficient and has been adapted for modern non-recyclable waste materials.

The process:

1️⃣ Residual waste arrives 
2️⃣ Combustion → Waste burns at 850°C+ in a controlled, oxygen-regulated environment
3️⃣ Energy generation → Heat creates steam that drives turbines, generating electricity
4️⃣ Cleaning → Advanced systems to remove 99.9% of pollutants from emissions
5️⃣ Metal recovery → Magnets extract metals from ash for recycling
6️⃣ Power export → Electricity goes to the grid; heat can warm local homes and be used by industry including agriculture

The result: 

• 3 tonnes of waste generates the same amount of electricity as 1 tonne of coal
• Produces a low-carbon energy alternative
• Provides reliable, 24/7 continuous power that complements intermittent renewables like solar and wind
• Generates both electricity and heat for nearby homes, businesses, and industries including agriculture
• Strengthens local energy security and grid stability
• Reduces landfill demand by over 90%
   

Energy from Waste is proven technology used safely worldwide. Over 450 facilities operate in Europe alone with many of them close to major cities near homes, schools, and farms.

Globally, Veolia operates more than 60 of these energy recovery facilities, bringing decades of expertise to Australia.

Paris heats its hospitals and museums (including the Louvre) using energy from these facilities. If they posed the risks some claim, would major European cities operate them in densely populated areas?
 

Let's clear this up — there's a world of difference.

Old-style incineration: Simply burning waste with little to no emission controls. No energy captured, no heat recovered. This outdated approach isn't used in modern facilities.

Modern Energy from Waste: State-of-the-art facilities that combust residual waste in highly controlled environments at 850°C+ with:

• ✅ Advanced flue gas cleaning systems (so near to zero emissions enter the atmosphere)

• ✅ Continuous emissions monitoring

• ✅ Energy recovery through steam turbines

• ✅ Strict regulatory compliance

• ✅ Minimal ash residue 

Here's what's changed: Environmental standards have become dramatically stricter over the past 30 years. For example, dioxin limits today are more than ten times tighter than they were in the 1990s.

The bottom line? Modern Energy from Waste is about control, technology, and purpose — turning waste into a resource, not just burning it. And it's clear - modern energy recovery facilities and ‘incineration’ are just not the same thing.
