OUR MAXI KILN
OUR STORY SO FAR
In December 2018, two Macclesfield residents, Kelvin Williams and Brian Lewis started discussing the merits of starting up a biochar centre in Macclesfield. There was mutual agreement that such a Centre, if run as a not-for-profit community enterprise, could have real benefits for the community and would demonstrate that individuals can do something about Climate Change.
Brian prepared an outline of a proposal for a Community Biochar Centre and circulated it to individuals, community groups and the Mt. Barker Council for comment.
A public meeting was held at the Macclesfield Institute on 22 January 2019 to discuss the proposal and to form a Steering Committee to take the project forward as a community effort. The meeting was well attended by local residents and landowners, and by representatives of Mt. Barker Council (Mayor Ann Ferguson), Federal Member for Mayo, Rebekha Sharkie, and Regional Development Australia (Fleurieu, KI and Adelaide Hills), Steve Shotton.
A Steering Committee was duly elected comprising: Brian Lewis (Chair), Kelvin Williams, Kath Thurmer, Stephen Heading, Tess Minett (Ward Councillor), Greg Marlu and Greg Sarre (a representative from Mt. Barker Council).
The Committee prepared a detailed proposal and submitted it to Council on 31 March 2019 asking for approval for the project and for assistance in locating a suitable site. A deputation to the Mount Barker Council meeting of 6 May by Brian Lewis and Kelvin Williams presented an overview of the proposal to Councillors.
On 20 May 2019 the Macclesfield Community Association Inc. agreed to auspice the maccy biochar group.
On 27 July 2019 we held our first public open day to demonstrate the making of biochar.
On 15 August 2019 we made our first batch of biochar on private property.
On 16 August 2019 we received our first delivery at our first collection point on Shady Grove Road.
By the end of our first season (mid-November 2019) we had made in excess of 1000 litres of biochar and (based on the analysis of our biochar by an accredited 3rd party in April 2020) we had avoided about 0.8 tonne of carbon dioxide.
By the end of our first full season in 2020 we had made in excess of 18000 litres of biochar and removed about 10 tonnes of carbon dioxide.
In May 2021 we became a Task Group of the Macclesfield Community Association Inc. and by the end of 2021 we had made overall 40,000 litres of biochar and removed over 20 tonnes of carbon dioxide since we started out in mid-2019.
