Tackling food waste will lead to triple wins: environmentally, economically, and socially.
Businesses can save money, through better food efficiency and planning. For every $1 a business invests in reducing food waste they can save $14. As landfill costs rise, diverting compostable and recyclable items is not only better for the environment but it is better for your wallet. And if you are in the habit of buying compost for your garden, creating your own is great for the environment and your wallet.
By creating a compost, Bokashi or worm farm or by sending your food scraps to an organic facility you can help create nutrient dense soil to help grow more food. By reducing the need for landfills we reduce land contamination. A healthy whenua (land) is fundamental to our Hauora; our physical, mental, spiritual, and social wellbeing.
When food is wasted it goes to landfill and emits methane which contributes to climate change and is at least 20 times the potency of carbon dioxide. Reducing food waste helps lowers greenhouse gas emissions in the food production process, and emissions from the decomposition of food waste in landfill. This is why reducing food waste is ranked as the third best global solution in addressing climate change.
A lot of the food we throw away is avoidable food waste – meaning it is food that could be eaten. Redistributing good quality, surplus food to those who need it can have a positive impact by reducing food poverty and increasing food security and community resilience. Check out the work of On The House, working with businesses including supermarkets, cafes, restaurants to recover food and serve it for free to people who need it.
The Government announced (2023) plans to get businesses ready to separate food scraps from general waste by 2030. This new legislation is being progressed alongside proposed new waste legislation that will affect most businesses and organisations that produce waste.
The average NZ café or restaurant generate approximately 2.8 tonnes (that is about 26 baby elephants) of food waste per year! Hospitality businesses have an important role to play in reducing food waste going to landfill.
Cafés and restaurants can reduce food waste by using seasonal produce, planning menus with reduced ingredient’s lists, rotating stock, using vegetable and fruit scraps in recipes, considering portion size, and offering doggy bags or allowing customers to BYO a takeaway container.
The University of Otago and WasteMINZ undertook research looking into the food waste generated by 20 restaurant and cafes, from six locations across Aotearoa. They did this through bin audits and an online survey. The following results provide an estimate of food waste in the New Zealand café and restaurant sector which include:
24,375 tonnes
61% avoidable
2.8 tonnes
