An Anaerobic Digestion Advocate in Australia



As the world’s population grows and fossil fuels run out, society will need to find alternatives to energy fuels. Thankfully, primary and secondary schools around the world are starting to integrate renewable energy into their science curriculum. Young children are learning about energy alternatives that can not only slow down global warming, but are also economical and feasible for implementation. It is common to learn about solar energy, wind energy and even geothermal energy, but what about anaerobic digestion? It seems like it’s often overlooked and left out of the discussion about environmentally-friendly energy sources! Thankfully, we have a new customer, David, who is making local efforts in NSW South Coast of Australia to put small-scale anaerobic digestion on the map.

When asked what his main motivation for buying HomeBiogas 2.0 was, David replied that his main motivation was for demonstration purposes. He wants to show family, friends and neighbors “what can be done to address environmental concerns in a practical way.” He views the HomeBiogas system, which turns food scraps from the kitchen into biogas that can then be used as renewable cooking fuel as “ more productive than just composting.”

David cooks on the biogas made from HomeBiogas every day for approximately 25 minutes. He makes yummy things like homemade soups and kombucha, and finds cooking them on the biogas stove to be extremely satisfying. Any leftovers from the cooking process are recycled back into HomeBiogas. David estimates that he throws away about 1.5 kg per day. And every time he feeds HomeBiogas 2.0, a wonderful nutrient-rich surprise flows out the system: liquid fertilizer.

“David remarked that he has an extensive food garden and the liquid fertilizer is highly valued”

The HomeBiogas team is extremely happy that David benefits from both the biogas and fertilizer and is also grateful that he takes the initiative to spread the word about biogas technology locally. He knows first-hand that the technology works, has a short ROI and is good for the environment and he cares enough to pass that knowledge on to others. Since he bought the HomeBiogas system for demonstration purposes, he says that all of his visitors are most impressed with it. Thank you David, for being a proud biogas advocate for your community. We hope that one day anaerobic digestion will be just as common as other renewable energies such as solar and wind energy.
