Waste DVD and CD disks were thermally degraded at 450 °C by a semi-batch process. 40 – 50 wt% of waste DVD and CD disks were converted into liquid product that consisted of phenol derivatives (~ 75 wt%), ...

Pyrolysis is a chemical decomposition process technique of biomass through heating without oxygen. The amount of biomass on earth is very abundant. The content of biomass such as cellulose and lignin makes biomass a material ...

The accessibility of clean water on the planet is extremely restricted. Therefore, the solution to obtain clean water is strongly required. Desalination using cacao pod husk activated carbon is one of method to obtain the ...

Functional endoscopic sinus surgery is a surgery to remove uncinate process in order to restore sufficient sinusventilation and drainagein nasal. However, there were a few cases withside effects ...

This paper reports the conceptual design of a household kitchen food waste composter. Several conceptual approaches, such as Quality Function Deployment (QFD), Concept Generation, and Concept of Evaluation using PUGH Method ...

As a lignocellulose source, banana peel has possibility to convert to be a solid biofuel. This current research applied Tanduk banana peels waste for main material of briquette. The aim of this research is to observe the ...

The development of polymer recycling is supported by research of degradation kinetics, pyrolysis products, and even reaction mechanisms. In this research, non-isothermal kinetic methods were used to estimate activation ...
