The Wonder Man Converting Food Waste into Natural Gas

Meet Andrew Fisher, the wonder man who has a working plan to deal with food waste. What more? He can turn it into natural gas. Isn’t that just amazing? The former New Zealand army special air services officer seems to be on a mission and a successful one indeed. You will be amazed to know that his company known as EcoStock Supplies has collected about 35,000 tonnes of waste every year for more than 12 years from various places such as supermarkets and different manufacturers. The waste food his company collects includes breakfast cereals, bread, chips, scraps of vegetables and pasta to name a few and then works on turning it into animal feed.


It is really encouraging for people and organizations interested in Biogas production. Let’s get to know more about Andrew Fisher’s mission and how it works. You can put all of the food waste ranging from meats to pizza with scrapings of Hawaiian at the bottom.
Under the leadership of Fisher, EcoStock is all set to establishing a whole new process and take the mission to another level by collecting hundreds of thousands of food waste to turn it into a great alternative of natural gas. A joint venture company Ecogas which again is getting benefitted from Fisher’s guidance has started developing a humungous $10 million plus anaerobic digestion plant in Reporoa.

Let’s take a look at how the process works. The plant can be likened to a huge black compost bin in which you put food waste and let the micro-organisms do their bit for some time. You get carbon dioxide, fertilizer and methane. Anaerobic digestion is the absolute opposite of composting. Biogas upgradation companies say that biogas produced due to the presence of anaerobic digester rises into the dome which later on is captured and piped out for further use. When asked about the time-frame fisher said that each lot of food waste takes between thirty to seventy days to get through.

Fisher also says that by the end of the year 2020 the anaerobic digester will be able to collect about 20,000 tonnes of organic food waste from various manufacturers in the area of Rotorua and Taupo. It includes bakeries, milk sheds, cool stores, and fruit graders. Natural microorganisms break the food waste at 37-41 degrees and generate Biogas. Cleaning and conversion of the collected biogas  into biocng then serves as a good alternative to natural gas.
