9 November – Ken Davey – Anaerobic Digestion and Biogas in the Circular Economy

CCL Australia Monthly National Meeting – Saturday 9 Nov 2PM AEDT

Ken Davey is a pioneering consultant on biogas and bioenergy project development, currently working on projects in Newcastle and Tonga. He says anaerobic digestion and biogas enables scalable, multi-element circular economy systems to form in support of a sustainable future.

We are still in the advent of the circular economy. Products from bio-based resources have a huge potential to grow in coming years. In the future ‘bio-economy’ wastes will be transformed to high-value products and chemical building blocks, fuels, power and heating. Biogas facilities will play a vital role in this development. They are sustainable factories where value is created for the local community from previously wasted materials. The anaerobic digestion system is able to digest a multitude of waste organic feedstocks, and produce a range of valuable renewable products while retaining and recycling vital nutrients, thereby providing an agricultural keystone for the circular economy.

One of the key outputs from a biogas facility is of course carbon dioxide, yet even this is a raw material to use wisely. It is an ideal input for seaweed/algae farming, along with other nutrients from the facility, and in turn can produce commodities ranging from human food to jet fuel, with an efficiency 10 times that of land based crops.

The biogas facility is not merely a concept of production of renewable energy and food, it also provides waste treatment, greenhouse gas reduction in agriculture and in energy, bio-fertiliser, and it serves to protect water quality in streams and aquifers. Sustainable biogas systems include processes for treatment of waste, for protection of environment, for conversion of low-value material to higher-value material, for the production of electricity, heat and biofuel. A key benefit is that biogas and anaerobic digestion systems are ‘dispatchable’ and can facilitate on-demand renewable electricity.

Please join us to learn more of this remarkable untapped technology.
