Smart Biogas plant
The “smart” part is not bio-gas, but the bio-gas-plant.
Because it can produce much more than just bio-gas!
A bio-gas plant produce bio-methane gas, CO2 gas, H2O gas and around 80% of the used biomass is available after as fertilizer. There is practically no waste and the basic products produced can be used in many different ways. Imagine such a gold mine in a country that has to import practically everything because it has no significant production capacity of its own! Even the electricity Unfortunately has to be imported from Thailand and is highly susceptible to disruption.
A bio-gas plant makes you self-sufficient and produces renewable resources locally, for which there is a large and long-term market in the country. Cambodia is a subtropical agricultural country and has everything that a bio-gas plant needs in abundance.
