Advanced analytical techniques for the extraction and characterization of plant-derived essential
oils by gas chromatography with mass spectrometry
Rabia Waseem
University of Malaya, Malaysia
In recent years, essential oils have a growing interest with positive health effects of their novel characteristics like antibacterial,
antifungal and antioxidant activities. For the extraction of plant-derived essential oils, there is the need of advanced analytical
techniques and innovative methodologies. An exhaustive study of hydro-distillation, supercritical fluid extraction, ultrasonic &
microwave assisted extractions, solid phase micro-extraction, pressurized liquid extraction, pressurized hot water extraction,
liquid-liquid extraction, liquid phase micro-extraction, matrix solid-phase dispersion and gas chromatography (one and two
dimensional) hyphenated with mass spectrometry for the extraction through various plant species and analysis of essential oils
have been provided. Essential oils are composed of mainly terpenes and terpenoids with lower molecular weight aromatic and
aliphatic constituents that are particularly important for public health.
Conversion of waste plastic into liquid hydrocarbon fuel

Waste Technologies LLC, USA
Waste Plastic is a huge problem in USA and around the world. This is global problem and because of various inventions
in the 20th century, plastics are everywhere. Society has found ample ways to use plastics. But users are less adept
at managing the material when they are finished with it—often after only one use. The volume of plastics being produced,
used, generated, and discarded is greater than ever before. Plastics therefore require increasing effort and ingenuity in its
management. Annually, of the 120 billion pounds of plastics produced in the United States, only about 6% or 4.8 billion pounds
are recycled. Inspite of all the news on plastic ban, plastic production is increasing. Waste Technologies LLC (WTL) has the
solution at its disposal. This technology can produce approximately 1.3 liter of “WTL fuel” from one kilogram of plastic waste.
The exact yield depends on the type of plastic, and the grade of WTL fuel desired. Typically, the process produces a residue of
less than 5% of the weight of the plastic waste. This residue is rich in carbon and may be an environmentally superior substitute
for coal with a higher BTU value. The WTL technology is able to cater to a wide range of diverse applications, including but
not limited to fuel, gas and electrical generation. NSR’s / WTL patented technology, in conjunction with WTL technology
and know-how, is a simple and economically viable process to decompose the hydrocarbon polymers of waste plastic into
the shorter chain hydrocarbons of liquid fuel. WTL believes that it can convert approximately one tonne of plastic into about
300 gallons of fuel at a cost of about $0.75-$1.00 per gallon and produces 4,205 ft3 (CFT) of light gas (C1-C4) byproduct
when developed to commercial size. WTL’s refining process is uncomplicated and promises to be very competitive with large
crude oil installations. In financial projections WTL uses $30/bbl. ($0.71 per gallon) for preprocessing and refining costs.
Other plastic recycling technologies generally have a very narrow band of plastics they can use. Nearly all recycling is done
with plastic designations 1 or 2 while designations 3 through 7 are virtually untapped (over 70% of all plastic fall within these
categories). A combination of economic and technological factors account for this situation. The advantage of WTL technology
is that it can produce a profitable product from material that society generally pays to throw away. It is this low cost feedstock
that is the key advantage.
