human and animal waste#

•  human and animal waste is

   raw sewage.

  
• Sewage is treated which means the water is separated and cleaned,

  leaving lots of brown sludge.

  
• This is processed and gets turned into dried pellets which can

  be burned instead of coal or gas.

  
• By not burning non-renewable energy sources, such as coal or gas, we are 

   saving on carbon emissions
