What are some problems we might encounter with producing biogas

2 reasons if you can?

Thanks guys!

The first is the growing amount of waste we produce – including also organic waste. When organic waste rots, it sets free CO2 and methane. Both gases are known to be greenhouse gases, which means, they make our earth warmer. And second, our modern society depends on the energy of fossil fuels such as oil, gas or coal. These fuels are limited and might be used up soon. Using them always means burning them, which again leads to a higher amount of CO2 in the atmosphere.
