Summary: The Brazilian Policy on Solid Waste highlights the importance of pickers
organizations in the integrated management of recyclable municipal solid waste,
establishing priority in involvement in the selective collection and reverse logistics
systems. However, only organizing in networks can achieve market efficiency to meet
the recycling industry selling large volumes of materials. Thus, this study aims to
define the location of transshipment and storage centrals of recyclable waste to a
network pickers organizations in the Espírito Santo through a mathematical model of
two-echelon Mixed Integer Linear Programming (MILP). To this end, the present
study aimed to evaluate the effect of estimating generation strategy of recyclable
solid waste, the effect of recyclable recovery goals proposed for the Brazilian Solid
Waste Plan, as well as the effect trucks carrying capacity in the financial result of a
reverse logistics network of recyclable waste. Thus, it was noted that the effect of
waste generation estimation strategy can impact on a financial results of the logistics
network in the order of 61%, which would result in a revenue gap of approximately
R$ 58,000 per week. A recovery goal of recyclable fraction of 30% for 2035 reflected
in a financial income of approximately R$ 467,000 per week. It was also noted that
as from projections targets above 40% recovery in 2035, begins the protagonism of
micro and small companies in the recyclable market (can reach 62% of companies
traded waste in the proposed network) due the verification of large surpluses
recycling companies. For cases analyzed, transport costs could reach 33% in relation
to total costs for homogeneous fleet of sixteen-ton trucks. With regard to occupant
load percentage, it was verified that ten-ton trucks and twenty one-ton trucks are
suitable for smaller and larger generation of municipalities, respectively. In all
scenarios, the financial result was positive, including scenarios which took into
account the current situation, from R$ 4.8 to 44.1 million annually.
