6. Environmental impact
6.1. Water
A great amount of water is consumed in nearly every stage of
the clay products manufacturing process. The preparation of the
clay follows the Atterberg standards (GRECO, 2012), as previously
described, whereas in the brush up phase water is exclusively
needed to even the surface of the pieces.
Additionally to the role water plays in the preparation of the clay,
it is also used to clean up tools and installments.
6.2. Electricity
On account of the baking stage, the clay preparation demands a
great deal of electricity, in particular during the dry up and backing
process. For the baking process an Etil electric oven was chosen,
considering its special refractory bricks cover, which keeps
the heat and optimizes the electricity consumption.
6.3. Toxic resources
Given that the prototypes are exclusively made with clay, with no
addition of enamel of any sort, the plates do not carry any toxic
substance in its structure.
7. Logistics
Considering that such projects are usually related to governmental
programs, its implementation depends much upon human
resources and materials available within the institution, or from
complex public bidding processes (ALVAREZ, 2003). In this context,
it is essential to make use of clay types which provide clear
product descriptions, for instance terracotta and chamote, making
the public bidding process and acquisition easier.
The plates’ storage strategy during the transportation is also
a huge concern, observing the limited alternatives of shipping
goods to the Antarctic continent: land transportation (trucks or
similar), ship or aircraft (or both combined), helicopter or boat
(or both combined) and eventually the human being. Within
this context, each piece has to be wrapped and stored into antibraking
packaging, capable to resist the correspondent mean of
transportation and temperature swings. The inside of the pack-
