Olympia Yarger, founder of agritech start-up Goterra which uses maggots to process food waste, is one of four inspiring residents to take out awards in the capital.

The four winners will join other state and territory recipients as finalists for the national awards announcement on January 25, 2023 in Canberra.

The winners were announced during a ceremony at the National Gallery of Australia on Wednesday.

Olympia Yarger is a climate action warrior, a maggot farmer and founder of the Insect Protein Association of Australia. She even had a fly named after her by the CSIRO (Hermetia Olympea, a soldier fly species from the Daintree rainforest).

The founder of agritech start-up Goterra, Ms Yarger is an insect farming pioneer and has developed an innovative waste management system that uses maggots to process food waste and reduce greenhouse gases.

Her "Maggot Robot" system houses larvae of the black soldier fly inside portable units. Food waste is fed to the maggots and, similar to a worm farm, the larvae's excretions become fertiliser. The maggots themselves become protein-rich feed for livestock and aquaculture.

It's already being used by Woolworths and in Sydney's Barangaroo precinct. So far, the 47 year old's system has processed more than 35,000 tonnes of waste and saved more than 66,000 tonnes of carbon emissions.

Kofi Owusu-Ansah is a Ghanaian-Australian poet, songwriter and rapper who uses hip-hop music to highlight issues such as racism and depression.

Mr Owusu-Ansah was born in Ghana in 1998. By the time he was two years old, his family had relocated to Canberra, where they continue to reside.

As a shy kid, he was attracted to poetry as a means of self-expression and self-exploration. Now, at 24 and on the cusp of an Australian tour with the Black Dog Band under the name of Genesis Owusu, he gets a similar kind of illumination from making music.

Dr Shamaruh Mirza is a medical scientist, but she knows that feeling connected and having someone to talk to is as important as any medicine for good health.

Originally from Bangladesh, Dr Mirza was seeing a lot of women dealing with depression as she did volunteer work among culturally and linguistically diverse groups in Canberra.

Wanting to give women of diverse backgrounds a safe space in which to discuss their challenges and gain confidence, she co-founded SiTara's Story in 2017. It would be somewhere women could discuss stigmatised topics without fear, form support networks and empower themselves.
