Ανάλυση των οικιακών απορριμάτων, τα οποία υπέστησαν ξήρανση, με σκοπό τον προσδιορισμό των φυσικοχημικών παραμέτρων τους όπως το PH και σακχάρων όπως άμυλο, κυτταρίνη, ελεύθερη γλυκόζη,τα οποία είναι απαραίτητα ώστε να εξαχθεί το συμπέρασμα αν το τελικό ξηρό υλικό είναι κατάλληλο για τη παραγωγή αιθανόλης. |

This thesis aims to present the qualitative characteristics of household biowaste in order to be
used for the
production of
second generation alcohol.
The first chapter describes the environmental issue, which led to the realization of this research.
Subsequently, referring to the European and international legal frameworks, which allows
the
biowaste management in
certain contexts.
The second chapter, r
efers to the main methods of biowaste management with particular
emphasis on their collection and treatment methods. Specifically, the methods of solid waste
collection and their treatment methods such as biological and thermal treatment methods
are
analyz
ed.
The third chapter, refers to the bioethanol production from lignocellulosic biomass. Specifically,
the main ch
aracteristics which
the biomass
should have in order to be able to be
use
d to
in
a
lcohol production are presented.
I
n addition the major pro
cesses of alcohol production at
international level are described.
In the fourth chapter, a detailed
description of the methodology used in this research is given. It
involves the installation of a prototype
system
for managing and processing household bi
owaste
in order to reduce drastically the mass and volume of the biomass and produce a suitable
dehydrated product for the production of second generation alcohol.
The fifth and sixth chapter
s, include the results and the characteristics of dried biomass
produced after processing in the prototype dryer system. The seasonal variation of sugars, which
contribute to the
alcohol production are presented initially.
The average of total soluble suga
rs,
glucose, starch and cellulose is estimated to 39,05%w/w, 2,05%w/w, 16,43%w/w and 18,1%w/w
respectively
for the year 2015.
Subsequently
,
t
he reduction of mass and volume is estimated
to
84,1% and
80,4%w/w respectively
. Finally
, the energy consumption of
system management is
specified
to
0
,9
4
kWhr/kg.
Finally in t
he seventh chapter,
it is concluded that the prototype biowaste management system
examined may be successfully used in biowaste processing for alcohol production. |
