Airports function as ecosystems, with numerous stakeholders—from airlines to aviation security, retailers, baggage handlers, border agencies, and even construction companies— all playing crucial roles in ensuring smooth operations and a positive customer experience.
They also all, inevitably, generate waste. To effectively manage waste across the airport, a targeted and co-ordinated approach tailored to each stakeholders’ waste profile is essential.With 18.5 million passengers travelling through Auckland Airport each year, enjoying the opportunity to eat, drink and shop, it is critical to engage all airport stakeholders in our waste minimisation efforts to achieve meaningful reductions in waste through avoidance, reduction, reuse, composting, and recycling.
Terminals
Food waste is one of the largest waste streams at airports. With over 40 food and beverage outlets and six premium lounges in the Auckland Airport terminals, a co-ordinated strategy is necessary to divert food waste from landfills.
This has involved providing separate bins in kitchens to help busy lounge and concessionaire staff easily sort food waste, as well as training food court cleaning staff to identify and remove contamination from public-facing food waste bins. In airside areas extra training was provided to kitchen and wait staff to ensure we keep within the biosecurity requirements and regulations.
As a result, we have doubled the amount of food waste sent to composting year-on-year, achieving a diversion rate of around 12% last year, with 225 tonnes composted in the 12 months to December 2024.
Preventing waste generation is the most effective way to reduce waste. Offering reusable serving ware in eateries is a key part of this effort, with our licensing rules increasingly mandating its use. Currently, 50% of terminal food and beverage outlets provide reusable crockery and cutlery. Where single-use items remain, they are predominantly commercially compostable and can be included in our food waste collections sent for composting.
This additionally eliminates the issues encountered with plastic food packaging often being rendered unsuitable for recycling due to contamination by food waste.
Biosecurity in NZ is regulated by the Ministry of Primary Industries (MPI) who impose strict controls on waste management in airside areas. In New Zealand it is sent for steam sterilisation and deep burial in landfill. However, we have developed processes in collaboration with MPI to recover recyclable materials from low-risk areas.
We have a purpose-built facility where we separate empty plastic bottles, newspapers, and menu cards from aircraft cabin waste for recycling. We also recover clean recyclables and kitchen food waste from premium lounges in the international terminal.
Our partnerships extend beyond waste diversion. We have collaborated with CAA/Aviation Security and our waste collection provider to repurpose prohibited items removed from traveller checked luggage. A common example is batteries, many of which are still in their original packaging. Since implementing a donation process six months ago, we have redirected over 1,000 kg of alkaline batteries to a local charity who donate them to schools and other charitable purposes.
We work with charitable organisations in other areas too, for instance, unclaimed lost property items such as clothing, prams, blankets, sporting goods, musical instruments and household goods are donated to a local organisation that supports people coming out of rehabilitation facilities, women’s refuge, refugees and families in need of support.
Over the eight years since this initiative began, it has expanded to include contributions from airport hotels and baggage service providers, leading to the donation of 9,000 kg of goods in the past year alone.
To further drive sustainability, we have established a Retailer Sustainability Working Group, where retail tenants attend quarterly workshops to share best practice and explore waste reduction strategies. These well-attended sessions promote collaboration and continuous improvement across terminal businesses.
