Presentation topics:


Moving on the up (the waste hierarchy)

How can we better enable reduction, reuse, and repair? We want to hear about initiatives that:

· Encourage reuse (from packaging, to buildings and everything in between)

· Tackle over-production and over-consumption

· Espouse the benefits of repair (for e-waste, mattresses, furniture or anything else)

· Apply a cultural perspective (such as Te Ao Māori, Pasifika, Chinese or Indian, to name a few) to normalise top of the waste hierarchy behaviour


Circular Economy

Are we there yet? So far there has been a lot of talk about a circular economy but not a lot of progress towards it, or is there? Maybe you want to talk about:

· The role of product stewardship in transitioning to a circular economy

· An indigenous circular economy model

· What a circular economy means in practise


Be a better ancestor

As a sector we want and need to reduce carbon emissions and waste. Tell us how you are:

· Innovating to tackle climate change and reduce waste

· Demonstrating that reducing emissions and waste go hand in hand

· Drawing on ancestral knowledge to provide solutions

· Developing onshore solutions for the waste we produce

Does the Ministry for the Environment’s focus go far enough? What sources of emissions are we missing?

Influencing behaviour through system change and vice versa

Which comes first – the system or the behaviour? Tell us how you are:

· Engineering a solution to waste

· Motivating people to change their behaviour

· Shaping a system to nudge a behaviour

· Designing out waste

He tangata, he tangata, he tangata - people are our greatest asset 

The well-known whakatauki He aha te mea nui o te ao? He tangata he tangata he tangata! translates as “What is the most important thing in the world? It is people, it is people, it is people”. This session reflects that sentiment, and we want your pitches on:

· Initiatives to enhance the mental and physical well-being of your workforce

· Recognising and celebrating the diversity of those working in the waste and resource recovery sector

· Initiatives or programmes to build capacity and develop the workforce within your sector


Kua hua te marama
This whakatauki refers to the completion of a full cycle and we are interested in hearing how this applies to organic materials. Tell us how you are:

· Reducing food waste in your organisation, or helping others to

· Turning residual food waste and other organic materials into products with beneficial use

· Applying a specific cultural lens to address this issue 

· Creating a demand for the output of organic materials processing

· Innovations across all sectors of the food chain to tackle food waste

Eutopia 2: moving from the RMA to the NBA

In November 2022 the Ministry for the Environment released drafts of the Natural and Built Environment Bill and the Spatial Planning Bill. Share your thoughts on:

· How the new regulatory framework will impact your industry

· What the new regional spatial strategies should look like

· Setting limits and targets for success



Following on from WasteMINZ’s Collaborative Workshop in November 2022, tell us how you are coming up with solutions to the challenges we are facing by collaborating with:

· Other sectors or sector groups within WasteMINZ

· Researchers and academics

· Central and local government

· the wider industry

Resource or rubbish? Managing surplus soils

Chief Executive and Secretary for the Environment Vicky Robertson said, “Land is central to our identity as people of Aotearoa New Zealand. It is our tūrangawaewae, our place to stand.”  Yet across the motu we dispose more than 800 kilo tonnes of soil to class 1 landfills every year. Are surplus soils a resource to be recirculated and reused or rubbish? Tell us how you are:

· Applying circular economy principles to soils
