High emissions of GHG and pollutants

 

Low viscosity

High toxicity

  

Low biodegradation rate

  

Non-renewable fuel

  

Low flash point

Biodiesel

Low emissions of GHG and pollutants

Expensive feedstocks (first- and second-generation biodiesels)

 

Low toxicity

Requires land for feedstock cultivation (first- and second-generation biodiesels

 

High biodegradation rate

Some feedstocks have low crop yields (first- and second-generation biodiesels)
