Write a short note about biomass
And biogas
Answers
Biomass and biogas are growing in popularity – if you’ll excuse the pun – in today’s ever more focussed ‘green society’. So what is the difference between biomass and biogas?
To understand the difference between biomass and biogas, first you must understand biofuels. Both biomass and biogas are what’s known as biofuels. Put simply, a biofuel is a fuel that has been derived from living matter – it could come from wood, manure or even algae.
Biofuels are considered to be carbon neutral because the Co2 produced when burning the fuel has already been extracted from the environment during the organism’s lifecycle. For instance, tree’s take Co2 from the environment and, through the process of photosynthesis, use it (and other nutrients) to grow and expels oxygen as a by-product. When the tree is burnt, this Co2 is release back into the environment in exchange for oxygen to fuel the fire. Due to this process, there has been no net-gain in atmospheric Co2.
Biomass and biogas are both forms of carbon neutral biofuel, simply in different forms.
