ARRIVAL

Your sustainable journey with COMO The Treasury begins even before you arrive, as we have thoughtfully designed every touchpoint to minimise environmental impact. This commitment to sustainability continues throughout your stay, from your room and surrounding, to our eco-conscious dining offerings.

Local Sourcing – Floral Decorations

Flower arrangements within the hotel are crafted from West Australian flowers with a longer life, ensuring a longer display period before replacement. We partner with local florist Fox and Rabbit, who specialise in native arrangements. Native arrangements last much longer than the typical hotel standard of three to four days; given the flowers and foliage are already accustomed to West Australia’s climate, a seven-day display window is possible. Additionally, COMO The Treasury does not use floral foam in any of our floral arrangements.

Energy Efficiency – Electric Vehicle Charging Station

Australians are embracing the shift to electric cars. We offer six 11kW charging destination stations as part of our valet parking service to support the change to electric vehicles.

IN THE RESTAURANTS

We believe that delicious food starts with the best ingredients possible, which is why sustainable, seasonal and locally-sourced produce is at the core COMO The Treasury’s culinary ethos.

Wildflower – Locally Sourced Menu

Our destination dining experience, Wildflower, offers a 93 per cent Western Australian locally sourced menu – the only course not fully from Western Australia is the cheese course, however all cheeses are still Australian.

Wildflower also partners with Tucker Bush to incorporate tangy, crunchy and sweet herbs and plants from the West Australian bush into their seasonal menu. From lemon myrtle to saltbush, these native plants have been used by local Aboriginal people for many thousands of years. The Tucker Bush range aims to introduce a truly local flavour into suburban cooking, working with communities who have unique stories to share. All of the plants in the Tucker Bush range play a vital role in our ecosystem, with some species under threat.

Post – Locally Sourced Ingredients

At Post Osteria and Bar, all proteins and vegetables are sourced locally, with just prosciutto, pasta flour and cheeses sourced from Italy to ensure an authentic Italian dining experience. 83 per cent of the Post menu features local produce from Western Australia or within Australia.

Seafood

For scallops, we partner with Endeavour Foods, the leading Rottnest Scallops supplier, who deliver fresh scallops on the day of catch from just 19 kilometres off the coast of Perth. Rottnest Island scallops are only harvested during their peak season, traditionally from September to November. Sustainability of fishing is Endeavour Foods’ paramount concern, as so they work in partnership with the Department of Fisheries to survey the scallop population several times per season, and have fitted their nets with escape panels that allow non-target species to swim out.

Mushrooms

For mushrooms, our sustainable partners are the Mushroom Guys, who aim to grow produce in conditions as close to the natural environment as possible. Gourmet mushrooms grow naturally on hardwoods, and so the Mushroom Guys blend sustainably-sourced West Australian hardwood sawdust into every one of their mushroom blocks. This hardwood sawdust is a waste stream of the West Australian timber industry; by using locally sourced waste materials, the Mushroom Guys divert almost 30 tonnes of sawdust waste annually. As the farm is located within the Perth metro area, there is also very little energy expenditure associated with transport and deliveries.

Coffee and Tea

99 per cent of our arrival amenities and minibar selections are sourced from Australia – and where possible from Western Australia – with Nespresso being the only exception.

Our coffee roaster, Mano a Mano, is based in Perth and sources ethical in-season coffee from farms and producers that share COMO The Treasury’s dedication to authenticity, transparency and quality. For tea, we partner with local retailer Teassential, located within the historic State Buildings.

IN THE ROOMS

Our guests are part of our sustainability journey, whether that is through reusing towels and linens to conserve water, or making use of our all-natural COMO Shambhala products.

Energy Efficient

All COMO The Treasury guest rooms are fitted with motion sensors that control the lighting and air conditioning systems, ensuring optimum conservation of our precious resources. We have installed acoustic panels on all room windows which keep the room cool in summer and warm in winter, reducing the need for the air conditioning.

Rooms are also serviced twice a day and bed linens changed every other day. We invite guests to hang any towels to reuse, and appreciate your collaboration in minimising our environmental footprint.

Water Efficient

The hotel is also equipped with high-efficiency water heaters, kitchen equipment, refrigeration systems and air conditioners, as well as low-flow energy-efficient toilets, faucets and showerheads.

Reducing Single-Use Plastic 

To reduce our plastic waste, COMO The Treasury has an onsite filtration and bottling system, which produces high-quality, low-impact still water. We do not utilise plastic straws in the hotel, whilst all takeaway packaging is biodegradable, with only wooden utensils offered. We provide locally grown and in-season fruits in each room, with in-room beverages decanted and served in reusable glass jars and bottles.

The COMO Shambhala products and amenities used across our hotel rooms are crafted from high-grade essential oils and all-natural products. They are free from parabens, sodium laurel sulphate, petrochemicals and synthetics, making them environmentally-friendly and sustainable.

BACK OF HOUSE

From eco-conscious products to innovative waste management, our team work hard behind the scenes to ensure that our cleaning and recycling efforts meet the highest of sustainable standards.

Cleaning Products

We use cleaning products that are biodegradable and gentle on the environment, and have replaced single-use chemical cleaning products with reusable Fibre technology textiles wherever possible.

Recycling

For our guests’ convenience, COMO The Treasury practices single-stream recycling, with materials being sorted by our team before being sent for recycling. On average, we recycle 15,000 kilograms of waste every month.

We operate an on-site glass crusher to compact waste glass and recycle it into new glass bottles. This has significantly reduced the volume of our glass waste, resulting in fewer trips to landfill and cutting down on disposal costs. Glass collection has gone from daily to twice a week, whilst recycling crushed glass reduces the need for raw materials, conserving natural resources and lowering carbon emissions.

Compostable Waste

Our cardboard baler was installed in January 2024 and compacts large amounts of cardboard into manageable bales, saving valuable storage space. Reducing the volume of cardboard waste means fewer collections, cutting down on transportation and disposal expenses: we have cut cardboard collection to twice a week instead of daily.

Our bin compactor was also introduced in January 2024. This allows us to compact non-recyclable waste, reducing the number of waste collections and cutting our on-site bins from 20 to 12. Compacting waste keeps it contained, reducing overflow, odours and potential hazards in waste storage areas.

Containers for Change

From October 2024, we are partnering with Containers for Change (with donations to Lifeline) to divert glass water bottles to the West Australia recycling scheme. We aim to divert 1000 glass water bottles per week, to be increased over time as we roll this out to more venues.

EMPOWEING THE LOCAL COMMUNITY

We work with partners to sponsor local charity events, enabling local organisations to grow and to raise vital funds. We also organise yearly volunteering activities for our employees, supporting Western Australia’s conservation.

In-Kind Donations

We partner with local charities such as MSWA, Lifeline, Breast Cancer Care and Telethon, offering in-kind donations and support of their community efforts.

Our worn linen is donated to the Rotary Club of Hillary. Sheets, towels, bathmats and pillowcases are sent to countries in need, improving hygiene standards in low-income areas and poorly-equipped hospitals. So far in 2024, we have donated 85 pillowcases, 40 towels, 45 bathrobes, 60 facecloths and 20 handtowels. This effort has successfully prevented 155 kg of textile waste from ending up in landfills.

Volunteering

In 2024, we have partnered with local planting groups, supporting senior volunteers in planting 450 trees along the Swan River. This will be a yearly team activity to further assist conservation efforts in Western Australia.

We are also proudly supporting MSWA, working collaboratively to ensure that we are able to offer services, facilities and funding for those affected by neurological conditions in Western Australia.
