Transcript of Biodiesel Life Cycel Assessment (LCA)
This presentation is on biodiesel Life Cycle
Assessment (LCA)
This presentation is presented at Aldrich Interdisciplinary conference at Memorial University of Newfoundland, Canada.
The presentation slides are made and presented by Zaman Sajid. For any research idea about biodiesel LCA please contact author at [email protected]
Resource Optimization of Biodiesel Production using Economical, Social,
and Environmental Life Cycle Assessment (LCA) and its comparison
with Petroleum-derived Diesel
“Break Down the Research Barriers”
- A theme of this conference
Biodiesel combustion reduces emissions of CO2 by 15.66% compared to petroleum diesel. (Sheehan et. al, 1998)
This is just one side of picture! We should look deep into their production systems

We should look deep into their production systems-
Means - we should look how much emissions is there at each stage of production

Life-cycle assessment is a technique to assess the environmental impacts associated with all the stages of a product's life from-cradle-to-grave (i.e., from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling).

Which production STAGE has the most emissions of CO2 and that stage need attention.
1. Environmental
2. Economical
3. Social
Sustainability
As an example:
Use of land to grow crops since we will use fertilizer to grow crops

CO2 This stage is Causing Highest Emissions
Performing Economic LCA on biodiesel life cycle would let us know which components are incurring more cost

Seeds’ Pressing
Seed Oil Transportation

Which stage is incurring the higest cost As an example: Buying of land has the highest cost

Industrial Production of Biodiesel
Biodiesel One kind of end-use

This stage has Highest Cost
Performing Social LCA on biodiesel life cycle would let us know how biodiesel cycle effects standard of living and community

As an example: Use of land effects human health the

Optimization To make as perfect, effective, or
functional as possible Or The process of making our resources
more efficient or optimal.
Environmental LCA How to reduce emissions from the highest
emission stage Economical LCA How to reduce cost from the most cost incurring
stage Social LCA How to minimize the impact of highest effecting
stage
We analyse what are the curial components and try to optimize those resources in all three pillars of sustainability.
STOP GLOBAL WARMING!
Hey earth! Who made you sad
It’s you!
If you have a car, instead of driving that, please walk to Bitters Restaurant for your lovely launch
THANK YOU!
