On 20 December 2019 the finalists challenging for C-Prize 2019 were announced.

BioFab NZ, Auckland

BioFab NZ

Traditional packaging and building materials use toxic materials, releasing large amounts of carbon dioxide during manufacturing and making up over 30% of global landfill waste. BioFab is creating packaging and building materials out of New Zealand-grown mushroom mycelium and wood chip (with hemp hurd feedstock). The biomaterial can be as light as polystyrene or as rigid and strong as plywood.

Compost Made Smart, Auckland

Compost made smart

Over a third of waste going to landfill is compostable. This organic waste is not only unnecessarily transported and processed using energy but also creates land, air and water pollution including rotting organic matter releasing greenhouse gas (methane). Compost Made Smart makes it easier for people to responsibly dispose of their organic waste with a compost sensing device linked to an App with convenient, simple directions.

EcoTex, Christchurch


EcoTex - Georgie Northcoat
Georgie Northcoat - EcoTex

Worldwide only 3% of textile waste is recycled responsibly and 15% of all textile waste comes from textile offcuts produced and discarded during the manufacturing process. Similarly, construction and demolition waste is responsible for approximately 50% of landfill material in New Zealand. EcoTex’s LessCut innovation is looking to create a circular economy in the industry by turning textile off cut waste into warm homes. Its patentable process will repurpose synthetic fibres into insulation materials.

Ngā Kaitiaki, South Auckland

Nga Kaitiaki - Amber Taylor
Amber Taylor- Nga Kaitiaki

The new types of complex environmental problems we face require a deeper understanding and a new approach to education. Ngā Kaitiaki see an opportunity for local people to become citizen scientists, restoring local ecosystems and monitoring environmental changes within their community. Their mobile Ahi Kā Rangers game enables users to move through their natural environments and earn rewards for the actions they take in improving their ecosystems.

OneBin, Hamilton


New Zealand alone sends 2.5 million tonnes of waste to landfill every year but a quarter of this landfill is actually recyclable material. OneBin is a smart waste bin that uses artificial intelligence (AI) and sensor fusion technology to automatically separate all categories of recyclables from waste. It can be easily installed in various locations such as kerbsides, shopping malls, airports, and office spaces.

Bluetide Aquaculture, Tauranga

Pamu Moana

Bluetide Aquaculture is farming protein from the sea as an alternative to land farmed protein that is often putting strain on our constrained ecosystem. It aims to both replenish and farm native clam species exclusive to New Zealand shores through aquaculture. The team has developed a special form of farming tailored to the bivalve surf clams, with a farming platform that can be set up both at sea and inland.

SES, Auckland


There is significant potential to reduce our energy use and environmental impact when it comes to heating and cooling spaces. The building sector in particular is responsible for about half of the world’s energy consumption. Smart Energy Storage (SES) is a system that absorbs natural cool or warm energy from the environment, stores it, and releases it when needed.

Loop HQ, Auckland

Wired Energy

Changes in the way we consume energy at home on mass can have a material impact on the environment. Loop HQ is accelerating residential carbon reduction by designing a smart, hardware enabled system at a price-point that will ensure accelerated residential uptake. 

Zincovery, Christchurch


Zincovery is out to tackle the hundreds of thousands of tonnes of zinc and acid released into landfill and wastewater every year through the steel galvanising process. With its demonstration plant it aims to recycle the industry’s spent acid and zinc for reuse within the galvanizing industry. The aim is to offer the service at a cost less than what these businesses pay to dispose of it.
