“Reviewing the potential and perspectives for Algal Production
and applications and resulting effects with Life Cycle and sustainability
assessment”
Abstract:
In the recent years, Life Cycle Assessment (LCA) inventory
accounting for all processing inputs and outputs, evaluates the benefits
and risks occurred in the long term. It has become a helpful tool to
quantify larger scale of production of multiple biofuels products in terms
of energy efficiency and pollutants or reduction of Green House Gas
(GHG) emissions and, the direct impacts or indirect consequences. While
evaluations of resulting risks and uncertainty during the process of
production are compared through mathematic models, and legalized ISO
system, LCA are becoming an important sustainability measurement
means for Pilots projects, Industrial producers and Government decision
makers. In particular, third generation advanced biofuels production
from algae culture, and second generation land crop productions as well,
devoted to transport combustion, are sources of debate. Yet, due the
interdisciplinary boundaries, large variability of the results are
challenging and call to be analyzed and further refined by different fields
specialists (biology, physiology, biogeochemistry, ecology, oceanography,
economy,…) and determine more accurately the interactions and
ecosystems chains, themselves. It seems the scarce inventories satisfy
with net energy ratio or low carbon alternative fuel performance
characteristics and are not at all considering: ecological interactions and
existence of cycles, soil, water, microbiological chains and carbon
balance, nor, the components of the production at each stage of the
conversion and total biomass involved or environmental impact for the
long term. This calls to more scientists of different fields to involve in the
research and by working together manage to make up with missing
understanding of the chain reaction and ecosystems balance phenomena
and offer closer analyze of by products, resource and waste equilibrium
versus high productivity-low carbon and low price energy.
