Biodiesel has several environmental benefits:
It is renewable: biodiesel is made from renewable resources
It is biodegradable: neat biodiesel (B100) degrades faster than petroleum diesel.
Potential for reusing waste products: certain waste products such as animal fats can be redirected away from our landfills.
GHG reductions: compared to diesel, biodiesel has the potential to reduce GHG emissions by over 80% on a lifecycle basis.
Reduces several tailpipe emissions: using biodiesel reduces several tailpipe emissions such as particulate matter, hydrocarbon, and carbon monoxide from most modern four-stroke CI or diesel engines. 1 Although, some studies measured a small increase in nitrous oxide (NOx) emission when using B100 instead of diesel.
Less toxic: a biodiesel blend would be less toxic than petroleum diesel.
Biodiesel can be produced locally in Canada and can provide local economies with a new market for their agricultural products and waste (reducing industry's disposal costs).
Agro-industry residues such as slaughterhouse waste, restaurant cooking oil, non-food-grade virgin oil or agricultural surplus once destined for a landfill is a commodity in the biodiesel business.
On a national level, biodiesel incorporated in the energy mix will encourage new business opportunities, greater investment, employment, and provide a new energy alternative.
