Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

ABSTRACT: Cotton is a wide known material since 6000 BC which now has its stock market. This material has a wide range of use and a huge annual production which explains why huge amounts of cotton waste and medical cotton waste exist. These amounts can be treated and become a considerable source of energy, instead of treated as common waste following the same procedures. The purpose of this study is to discover whether cotton is an efficient material for energy purposes and then to see in what conditions its gross heat of combustion can be maximized. More specifically we used a blast furnace in order to achieve torrefaction. The conditions applied were a non-isothermal heating up to 340o C for 20-50 minutes with 2.5 min step. The investigations of how pretreatment conditions, affected cottons gross heat of combustion happened in a calorimeter. The diagrams show analytically the dependence between time and temperature with gross heat of combustion.

KEYWORDS: cotton, torrefaction, medical waste, gross heat of combustion, recycling, severity factor.
