Hire Wash Against Waste Trailer

For small, medium or large scale events

WAW small

A locally designed and developed trailer powered by solar PV with solar hot water washing facilities that enables events to dramatically reduce the waste they produce. The trailer includes quality cutlery and crockery for up to 250 people.

It’s an ideal way to make your event more sustainable by greatly reducing the materials sent to landfill. It is a highly visible public education tool that raises awareness of sustainable catering practices and the wise use of water both on a commercial and individual level.

Wash against waste is saving the environment a total of 383 IMG_9352kgCO2e/day by replacing disposable cutlery and crockery (on the basis of 50% plastic and 50% paper products) with SS or melamine cutlery and crockery. That is equal to traveling a distance of ~1,277 km in an average car, and about the same distance traveling from Canberra to Brisbane.

Volunteers typically have a great time working on the trailer and contributing in a practical way to reducing waste.

Terms & Conditions

1. Applications for the use of the MASG Wash Against Waste Trailer and Stock and Equipment will only be confirmed once the application form is received by the WAW Co-ordinator.

2. Applicants must have completed (or have a member of their organisation who has completed) the WAWT operations training and are registered with MASG as an accredited WAWT operator, or MASG will provide a WAWT operator at a charge of $25 per hour.

3. Trailer to be collected from and returned to MASG in Castlemaine during office hours (unless a specific alternative arrangement is made with the WAW Co-ordinator).

4. Applicants arranging to collect the WAW Trailer should note that the unit weighs 1,900 kgs in operational form and requires a tow vehicle with a minimum 2,000 kgs towing rating.

5. Hired Trailer and Stock and Equipment becomes the responsibility of the hiring organisation after collection at MASG, and responsibility ceases following its return to MASG. Hirers must wash, count, and repack stock and equipment in its delivery containers before return. Dirty stock returned will be washed by MASG at the hirer’s expense, and such costs deducted from the security deposit.

6. Hirers agree to pay a $100 security bond payable to Mount Alexander Sustainability Group on or before collection. This bond is refundable following the correct return of the Trailer and Stock and Equipment.

7. The WAWT needs access to mains water and 240V mains power (just in case there is not enough sunshine for the trailer to operate on solar power) and access to a gully trap or toilet for disposal of water.

8. Four volunteers each hour are required to support the trained operator and operation of the trailer – if you do not have these volunteers, then you can apply to MASG to support you, at an additional charge.

9. MASG provides insurance cover on any trained operators and volunteers that we may provide to support your event.

10. Insurance for any trained operators or volunteers that you organise for the operation of the trailer is the hirer’s responsibility.

11. A replacement cost will be charged for any lost or damaged items or items that are returned dirty.


Sponsorship opportunities available if you fancy your business or organisation’s logo featuring at large. 

Did you know? That there is only one other wash against waste style trailer in the whole of Australia, which was modelled from this simple idea.

A simple idea that carries a whole lot of weight, in the challenge to encourage events to consider reusable cutlery and crockery, reducing landfill and waste, whilst creating a glorious social engagement.


Currently the trailer is sponsored by the Maldon and District Community Bank and has recently received funding from the Loddon Mallee Waste & Resource Recovery Group.

MASG would also like to thank Loddon Mallee Waste and Resource Recovery Group for their sponsorship of $750 enabling us to buy aprons and reusable latte cups for our Wash Against Waste Trailer program.

Our aprons have just been made locally by Heather Oliver of Deemu and screen printed with our logo by Fi and Tex at Big Tree T-Shirts in Guildford (all made within a 10k radius!).
