Wave and Tim open up the virtual mail bag and dig into your questions. We chat about Project Drawdown, Dr Paul Hawken and regenerative farming. Dr Hawken is on a mission to remove existing carbon in the air (rather than just reducing what we're putting out in the air now). Short answer: Have a listen to our soil episode! We cover a lot of ground (lol).

We also chat about the effect of dirty containers on your recycling and wonder how far we can move the waste behaviour needle. We explore why is NZ so far behind in banning single use plastics and learn what Wave's pet plastic peeve is.
Also in this ep; how to combat single use plastics in the supermarket and what comes after we win that battle; How businesses can do the right thing; And is government conducting effective public information/behaviour change campaigns?

Tim and Wav are joined by Auckland Councillor Richard Hills. Richard is the Chair of the newly formed Environment and Climate Change committee and is passionate about public transport, stopping urban sprawl and protecting our environment. We discuss what it's actually like to work in local government, if the council actually cares what we have to say, and how to effectively lobby for change in your region.

We also chat about how seriously the Council takes climate change, what declaring a climate emergency actually means and the anticipated effects of climate displacement on New Zealand, especially on our biggest city.

Tim's in the expert chair today as he shares his research into the impacts of the object we use more than any other, every single day; Our phone! We explore the three major life stages of a phone, 1) Mineral extraction for components 2) Assembly 3) Disposal.

The true cost of mineral extraction to get the rare Earth minerals needed to make all the different parts of a phone are hidden from us and there's a good reason. Child labour, dangerous conditions and underpaid workers in developing countries are all part of the smartphone production line. The (largely) Chinese-assembled smartphones are also produced in very dubious conditions. The disposal of these devices (and e-waste in general) needs to be considered because these toxic elements can leach into soil, groundwater and even start fires at dumb sites.

On the positive side of things; NZ's own MINT Innovation claims to have developed a revolutionary process for recapturing rare Earth elements from reclaimed electronics including phones, which reduces our need to harvest more from the Earth and could prevent huge amounts of e-waste going to landfill.

Then there's Fairphone, the Dutch smartphone maker who are mindfully producing devices using best worker practices and environmental sustainability at its core. Their phones also use a modular design so you won't have to throw away phone because the screen's cracked or battery barely holds a charge, you can just order that component from Fairphone and slot it in. This can extend the life of the device many times over and reduces the amount of devices purchased/produced by consumers.

Kate Hall is a 23-year-old Instagram inspirer (nee influencer), entrepreneur and sustainable fashion enthusiast. She lived in Mongolia at an early age which made an indelible mark on thinking about global supply chains and where our stuff comes from. In this chat with a leading green member of Gen Z, we discuss communicating online, the importance of slowing down and how to avoid the paralysis of perfectionism.

Kate has partnered and worked with many figures in the New Zealand fashion industry to try and figure out how NZ can lift its fashion game.
Kate is aiming to change people's life choices on buying and living ethically. Importantly, she stresses the importance of kindness.

The True Cost documentary (which was highly influential on Kate) is available here. 
Kate is on Instagram @EthicallyKate and at Facebook.com/EthicallyKate

This episode is focused on good news in sustainability. Waveney and Tim trade big stories on oil staying in the ground in Norway, battery breakthroughs, and how the flow of global capital is starting to move away from ecologically unsustainable business practices. We also celebrate the incredible work being done by NZ's Environment Centres.

Dr Niki Harré is a Psychology Professor from The University of Auckland who focuses on sustainability and social change (among other areas). She authored Psychology for a Better World (check out her video summary of the book here) and has contributed significantly to the academic world on thinking about sustainability and how we can change societal behaviours for the common good.

This fascinating conversation draws on Niki's ideas that challenge the status quo in several ways. She builds on the ideas put forward in the book Finite and Infinite Games (James Carse) – the framework of identifying that most pursuits can be split into finite games (played for the purpose of winning) and infinite games (played for the purpose of continuing the play).

We sit down and chat to the incredible Glen Herud, founder of Happy Cow Milk.
Glen started off as a dairy farmer then went to renting appliances, then invented a new way to get milk and keep cows happy. Then we went bankrupt. Then he created an all-in-one machine that can milk cows on the go (with their calves nearby to reduce their stress immensely), pastoralise, bottle and sell the milk. All in a machine that can fit on the back of an e-bike! He's been through financial ruin, a borderline emotional breakdown working 19 hour days and a lot of personal growth but the result is a potentially completely revolutionary system to democratise milk and keep cows happy in the process.

This episode is about how to ditch landfills. Landfills don't work. We all hate them. We don't want them in our backyards. They are getting further away from our cities – Dome Valley (between Warkworth and Wellsford).  They produce tonnes of methane and an eternal leachate problem which you don't want in waterways. So burning all this waste to generate energy is a great idea, right?!

Waveney's been researching expert opinion and data from both sides and presents a far more complex picture of waste to energy than you may know. This includes four different kinds of W2E: Incineration, Gasification, Pyrolysis and Anaerobic digestion (aka bio-digestion).

W2E is an attractive alternative to landfill: It creates energy; It could reduce the need for landfills; It reduces the volume of rubbish; It creates new jobs when plants are opened and it doesn't mean that all the rubbish has to be gobbled, we can still recycle or repurpose useful items. 

HOWEVER, that leads us to the five big issues with W2E. It isn't a very efficient way to make energy. The toxic ash and filters need to go somewhere (often landfills). It doesn't vanish waste, it creates a very dangerous concentrated end product. It's the lowest waste jobs creator (1 job for 10,000 tonnes vs landfill's 6 jobs, recycling's 36 jobs and waste recovery's 200-300 jobs). It's very expensive, which creates a dependency of waste generation long-term, making it incompatible with zero waste goals.

Have a listen and please share with your friends who are passionate or just curious about waste to energy solutions. Thank you to the following people who helped with this episode; Michael from Sierra Energy, Hannah and Liam from the Rubbish Trip, Val from the Zero Waste Network, Trish A for your winning question on our Facebook page.
