[su-re.co venture] CO2 reduction potential of our biogas digester


Hi This is Takeshi, CEO of su-re.co


I do not do social media much although I know I have to do as a business owner and a scientific researcher who is the most ego-centric profession fighting to be the first author (^^;). Besides posting my kids surfing, I am still checking my LinkedIn account as I got messages may become some earnest projects. Most times, my messages are head-hunters or suspicious online consulting opportunities, but I also have got multi-year projects ;-). So, even if you are not a selfie person, I recommend updating and checking your LinkedIn.


Today, I also received a message which is quite interesting and informative to understand our biogas digester, so I share the non-privacy part.





=====

I got a seed fund from a foundation to make carbon offsetting with our biogas digester via blockchain. Our technology has no problem to instal in a pandemic because we make the biogas bag at our office instead of on-site. The 40 units of digesters will be installed with the fund, and we will sell the offset via our website as a subscription. Are you interested in collaborating with this initiative (^^;)?



The project will start early next year, but we started two EC Horizon2020 projects this year which include biogas as well. These two projects are research projects, and we will study the social and political impacts as well as carbon offset capability not only reduction of CO2 emission but also decarbonisation effects.


Our biogas bag (2 m^3) will reduce 5 tons of CO2 every year if it replaces the usage of firewood. If our biogas is used as an alternative to LPG, it will reduce 240kg CO2 / year. It depends on the location, but the scenario to replace LPG by the biogas will be more likely in Bali. In other islands, the firewood replacement is more likely. In reality, it will be mixed. Assuming we replace firewood 100%, we need 30 biogas to reduce 150 ton CO2 / year. If replacing LPG, we need the digester 20 times more. This calculation does not include the methane reduction and decarbonisation into bio-slurry (organic fertiliser), so the "5 tons of CO2 / year" is still underestimated. We will study this in one of the EC projects.
