DESCRIPTION

Biodiesel is an environmentally friendly fuel as compared to petroleum-derived diesel. This work aims to evaluate how much we are compromising with environment, society and investment returns by biodiesel production. Biodiesel is a long-chain alkyl ester, produced by the Chemical reaction of oil/fat with alcohol. The industrial production of biodiesel has various roots. The current study proposes to perform Life Cycle Assessment (LCA) on base-catalysed production method. The study has three steps 1) performing LCA on base catalysed production system. The LCA is performed using three pillars of sustainability: economic, social, and environmental prospects 2) analyze the results of LCA and assess the most sensitive components in the production 3) resource optimization: In this step, those critical components would be optimized to get the best utilization of resources. Concerning the economical LCA, this would be the best and attainable ways to lower the biodiesel production cost, concerning the social aspects, it would be the ways through which human health could be made less effective while producing biodiesel and concerning the environment, it would be the ways through which environmental impacts of biodiesel production could be minimized. The resource optimization study on those susceptible components would also yield how much possibly cost could be minimized, adverse social and environmental impacts could be reduced. These three steps would also be studied for petroleum-derived diesel and the results comparison would yield which fuel is really an environmentally friendly fuel, based on life cycle study rather than merely its combustion properties.

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]

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).

As an example:

Use of land to grow crops since we will use fertilizer to grow crops

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.
