N2 - To further advance the development
and implementation of glycerol-based
biorefinery concepts, it is critical to analyze the glycerol conversion
into high value-added products in a holistic manner, considering both
production as well as the logistics aspects related to the supply
chain structure. To address the optimal design and planning of the
glycerol-based biorefinery supply chain, in this work, we propose
a multiperiod, multistage, and multiproduct Mixed Integer Linear Programming
optimization model, called GlyThink, based upon the
maximization of the net present value (NPV). The proposed model is
able to identify operational decisions, including locations, capacity
levels, technologies, and product portfolio, as well as strategic
decisions such as inventory levels, production amounts, and transportation
to the final markets. Several technologies are considered for the
glycerol valorization to high value-added products. Existing countries
with major production and consumption of biodiesel in Europe are considered
as candidates for the facility sites and demand markets, and their
spatial distribution is also carefully studied. The results showed
that (i) the optimal solution that provides the best NPV is obtained
by establishing a multiplant supply chain for the glycerol-based integrated
biorefinery, built upon four plant site locations (Germany, France,
The Netherlands, and Italy); (ii) if a single-plant alternative is
to be selected, Germany stands out as potentially the best location
for the integrated biorefinery; (iii) government incentives might
play a decisive role in the growth of a glycerol-based economy showing
improved economic feasibility; and, last, (iv) the optimal product
portfolio suggested is based on the production of succinic acid and
lactic acid, followed by epichlorohydrin and poly-3-hydroxybutyrate
(PHB).
