For many Melburnians, the garage is more than just a place to park the car. It’s a workshop, a storage unit, and the designated home for all those “I’ll deal with that later” items. But lurking on those shelves, behind the lawnmower, are often a range of common products that are classified as household hazardous waste (HHW).

These aren’t just regular rubbish; they are materials that can pose a significant risk to your family, your pets, and the environment if not stored and disposed of correctly. This guide will help you identify the hidden dangers in your garage and understand the safe, compliant way to manage them in Victoria.

What Exactly is Household Hazardous Waste (HHW)?

Household hazardous waste refers to any product used in the home that is flammable, corrosive, toxic, or reactive. Essentially, if the label has warnings like “Danger,” “Poison,” or “Flammable,” it’s a good sign you’re dealing with HHW.   

When these items are thrown in your regular bin, they can cause fires in collection trucks, explode at recycling facilities, or leak harmful chemicals into our soil and waterways, posing a threat to public health and local ecosystems.   

A Checklist of Common Dangers in Your Garage

Take a walk through your garage and see if you can spot any of these common hazardous items. You might be surprised by how many you find.

• Automotive Products: That half-used bottle of brake fluid or the old container of antifreeze are hazardous. This category includes used motor oil, old fuel, car batteries, and solvents.   
• Paints and Solvents: Leftover paint is one of Australia’s most common forms of HHW. This includes oil-based paints, thinners, varnishes, and wood stains, all of which are flammable and contain harmful chemicals.  
• Garden and Pest Control: While essential for keeping the garden looking good, products like pesticides, herbicides, fungicides, and pool chemicals are toxic and must be handled with care.   
• Gas Cylinders: Old BBQ gas bottles, butane canisters from camping trips, and expired fire extinguishers are all pressurised and pose an explosion risk if damaged or heated.  

  Batteries: Car batteries contain corrosive acid, while the lithium-ion batteries in many power tools can cause intense fires if damaged or short-circuited.  

The Risks of Improper Storage and Disposal

Leaving these items sitting in the garage indefinitely isn’t a safe solution. The risks are real:

• Fire Hazard: Flammable liquids like old petrol or solvents can ignite, while pressurised cylinders can explode in a house fire, accelerating the danger for your family and emergency services.
• Health Risks: Leaking containers can release toxic fumes into your home. There’s also a significant poisoning risk for curious children and pets who might gain access to them.  
• Environmental Damage: Illegally dumping these items or putting them in your bin means they end up in landfill, where they can contaminate the environment for generations.  

The Safe and Compliant Way to Dispose of HHW in Victoria

The most important rule is that household hazardous waste cannot go in your kerbside bins. So, what are your options?  

• Council Drop-Off Sites: Many local councils have transfer stations or resource recovery centres that accept certain types of HHW, though fees and restrictions often apply.  
• “Detox Your Home” Events: Sustainability Victoria runs free “Detox Your Home” events across the state, providing a great way to dispose of a wide range of chemicals. However, these events are infrequent and require you to transport the materials yourself.
